Merge branch 'main' into feat-go-version-file-by-default

Resolve merge conflicts:
- action.yml: combine auto-detect description with .go-version/.tool-versions support
- versions.yml: keep auto-detect-go-mod job alongside new tool-versions/go-version jobs
- README.md: keep auto-detect section, adopt main's link to advanced-usage docs
- tests: keep auto-detect tests alongside new go-download-base-url tests

# Breaking changes in V6
## Breaking changes in V6
- Improve toolchain handling to ensure more reliable and consistent toolchain selection and management.
- Upgraded from node20 to node24.
> Make sure your runner is on version v2.327.1 or later to ensure compatibility with this release. [See Release Notes](https://github.com/actions/runner/releases/tag/v2.327.1)
The V6 edition of the action includes:
- **Upgraded Node.js runtime from node20 to node24**
> Make sure your runner is on version v2.327.1 or later to ensure compatibility with this release. See [Release Notes](https://github.com/actions/runner/releases/tag/v2.327.1)
For more details, see the full release notes on the [releases page](https://github.com/actions/setup-go/releases/tag/v6.0.0)
- **Go toolchain**
- Supports both `go` and `toolchain` directives in `go.mod`. If the `toolchain` directive is present, its version is used; otherwise, the action falls back to the `go` directive.
# V5
The V5 edition of the action offers:
- Upgraded Node.js runtime from node16 to node20
- **Cache key update**
- By default, the cache key for Go modules is based on `go.mod`. To use `go.sum`, configure the `cache-dependency-path` input.
See full release notes on the [releases page](https://github.com/actions/setup-go/releases).
The action will first check the local cache for a version match. If a version is not found locally, it will pull it from
the `main` branch of the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json)
repository. On miss or failure, it will fall back to downloading directly
from [go dist](https://storage.googleapis.com/golang). To change the default behavior, please use
the [check-latest input](#check-latest-version).
## Usage
**Note:** The `setup-go` action uses executable binaries which are built by Golang side. The action does not build
golang from source code.
See [action.yml](action.yml).
Matching by [semver spec](https://github.com/npm/node-semver):
<!-- start usage -->
```yaml
- uses: actions/setup-go@v6
with:
# Version or version range of Go to use
go-version: '1.23'
# Path to go.mod, go.work, .go-version, or .tool-versions file
# Note: if both go-version and go-version-file are provided, go-version takes precedence.
go-version-file: 'go.mod'
# Set this option if you want the action to check for the latest available version
# Default: false
check-latest: false
# GitHub token for authentication
token: ${{ github.token }}
# Used to specify whether caching is needed.
# Default: true
cache: true
# Path to dependency files for caching
cache-dependency-path: 'go.sum'
# Architecture to install (auto-detected if not specified)
architecture: 'x64'
# Custom base URL for Go downloads (e.g., for mirrors)
go-download-base-url: ''
```
<!-- end usage -->
**Basic:**
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '^1.13.1' # The Go version to download (if necessary) and use.
- run: go version
go-version: '1.25' # The Go version to download (if necessary) and use.
- run: go run hello.go
```
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: '>=1.17.0'
- run: go version
```
**Version resolution behavior:**
The action resolves the requested version in the following order:
1. **Local cache** - Checks the local tool cache for a matching [semver](https://github.com/npm/node-semver#versions) version.
2. **go-versions repository** - If the requested version isnt available in the tool cache, it pulls the version manifest from the `main` branch of the [go-versions repository](https://github.com/actions/go-versions/blob/main/versions-manifest.json).
3. **Direct download** - If that lookup misses or fails, it will fall back to downloading directly from the [official Go distribution site](https://go.dev/dl).
To change the default behavior, please use
the [check-latest input](docs/advanced-usage.md#check-latest-version).
> **Note**: The `setup-go` action uses executable binaries built by the Go team and does not build Go binaries from source code.
## Supported version syntax
The `go-version` input supports the following syntax:
- Specific versions: `1.25`, `1.24.11`, `1.24.0-rc.1`, `1.23.0-beta.1`
- SemVer version range syntax: `^1.25.1`, `~1.24.1`, `>=1.25.0-rc.1`, `<1.25.0`, `>=1.22.0 <1.24.0`
- Aliases: `stable`, `oldstable`
- Wildcards: `1.25.x`, `1.x`
For details on Semantic Versioning, see [the semver package documentation](https://github.com/npm/node-semver).
> **Note**: Due to the peculiarities of YAML parsing, it is recommended to wrap the version in single quotation marks:
>
@ -59,138 +100,7 @@ steps:
> go-version: '1.20'
> ```
>
> The recommendation is based on the YAML parser's behavior, which interprets non-wrapped values as numbers and, in the case of version 1.20, trims it down to 1.2, which may not be very obvious.
Matching an unstable pre-release:
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: '1.18.0-rc.1' # The Go version to download (if necessary) and use.
- run: go version
```
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: '1.16.0-beta.1' # The Go version to download (if necessary) and use.
- run: go version
```
# Usage
See [action.yml](action.yml)
## Basic
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: '1.16.1' # The Go version to download (if necessary) and use.
- run: go run hello.go
```
## Check latest version
The `check-latest` flag defaults to `false`. Use the default or set `check-latest` to `false` if you prefer stability
and if you want to ensure a specific Go version is always used.
If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally
cached version is not the most up-to-date, a Go version will then be downloaded. Set `check-latest` to `true` if you
want the most up-to-date Go version to always be used.
> Setting `check-latest` to `true` has performance implications as downloading Go versions is slower than using cached
> versions.
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: '1.14'
check-latest: true
- run: go run hello.go
```
## Using stable/oldstable aliases
If `stable` is provided, action will get the latest stable version from
the [`go-versions`](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository manifest.
If `oldstable` is provided, when current release is 1.19.x, action will resolve version as 1.18.x, where x is the latest
patch release.
**Note:** using these aliases will result in same version as using corresponding minor release with `check-latest` input
set to `true`
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: 'stable'
- run: go run hello.go
```
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: 'oldstable'
- run: go run hello.go
```
## Caching dependency files and build outputs:
The action has a built-in functionality for caching and restoring go modules and build outputs. It
uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood but requires less configuration settings.
The `cache` input is optional, and caching is turned on by default.
The action defaults to search for the dependency file - go.sum in the repository root, and uses its hash as a part of
the cache key. Use `cache-dependency-path` input for cases when multiple dependency files are used, or they are located
in different subdirectories. The input supports glob patterns.
If some problem that prevents success caching happens then the action issues the warning in the log and continues the execution of the pipeline.
**Caching in monorepos**
```yaml
steps:
- uses: actions/checkout@v5
- uses: actions/setup-go@v6
with:
go-version: '1.17'
check-latest: true
cache-dependency-path: |
subdir/go.sum
tools/go.sum
# cache-dependency-path: "**/*.sum"
- run: go run hello.go
```
## Getting go version from the go.mod file
The `go-version-file` input accepts a path to a `go.mod` file or a `go.work`
file that contains the version of Go to be used by a project. The version taken
from thils file will be:
- The version from the `toolchain` directive, if there is one, otherwise
- The version from the `go` directive
The version can specify a patch version or omit it altogether (e.g., `go 1.22.0` or `go 1.22`).
If a patch version is specified, that specific patch version will be used.
If no patch version is specified, it will search for the latest available patch version in the cache,
[versions-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json), and the
[official Go language website](https://golang.org/dl/?mode=json&include=all), in that order.
> The recommendation is based on the YAML parser's behavior, which interprets non-wrapped values as numbers and, in the case of version `1.20`, trims it down to `1.2`, which may not be very obvious.

For more information about semantic versioning, please refer to [semver](https://github.com/npm/node-semver)
documentation.
## Using `setup-go` on GHES
`setup-go` comes pre-installed on the appliance with GHES if Actions is enabled.
When dynamically downloading Go distributions, `setup-go` downloads distributions from [`actions/go-versions`](https://github.com/actions/go-versions) on github.com (outside of the appliance).
These calls to `actions/go-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting).
If more requests are made within the time frame, then the action leverages the `raw API` to retrieve the version-manifest. This approach does not impose a rate limit and hence facilitates unrestricted consumption. This is particularly beneficial for GHES runners, which often share the same IP, to avoid the quick exhaustion of the unauthenticated rate limit.
If that fails as well the action will try to download versions directly from https://storage.googleapis.com/golang.
If that fails as well you can get a higher rate limit with [generating a personal access token on github.com](https://github.com/settings/tokens/new) and passing it as the `token` input to the action:
```yaml
uses: actions/setup-go@v6
with:
token: ${{ secrets.GH_DOTCOM_TOKEN }}
go-version: '1.18'
```
If the runner is not able to access github.com, any Go versions requested during a workflow run must come from the runner's tool cache.
See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)"
for more information.
For more usage examples, please refer to the section: [Using go-version input](docs/advanced-usage.md#using-the-go-version-input) of the [Advanced usage](docs/advanced-usage.md) guide.

## Caching dependency files and build outputs
The scripts and documentation in this project are released under the [MIT License](LICENSE)
The action includes built-in caching and restoration for Go modules and build outputs. It uses
[toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood, but requires less configuration.
The `cache` input is optional, and caching is enabled by default. To disable caching, set `cache: false`.
# Contributions
By default, the action looks for `go.mod` in the repository root and uses its hash as part of the cache key. Use the `cache-dependency-path` input when you have multiple dependency files, or when theyre located in different subdirectories. This input supports glob patterns.
Contributions are welcome! See [Contributor's Guide](docs/contributors.md)
If caching cannot be performed for any reason, the action logs a warning and continues workflow execution.
For examples of using `cache-dependency-path`, see the [Caching](docs/advanced-usage.md#caching) section of the [Advanced usage](docs/advanced-usage.md) guide.

## Using the `go-version` input
### Specifying a Go version
For repeatable builds, specify the **exact major, minor, and patch version** (such as `1.25.5`):
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25.5'
- run: go run hello.go
```
- The only downside is that setup may take a little longer. If the exact version is not already installed on the runner due to more recent versions, the exact version will have to be downloaded.
You can specify **only a major and minor version** if you are okay with the most recent patch version being used:
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
- run: go run hello.go
```
- There will be a single patch version already installed on each runner for every minor version of Go that is supported.
- The preinstalled patch version is generally the latest available. When a new patch is released, it replaces the previously preinstalled version on the runner.
- Using the most recent patch version speeds up setup because the required Go version is already installed on the runner and no download is needed.
To try a **pre-release**:
Download and use beta or RC Go versions as needed.
```yaml
# RC version
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25.0-rc.2'
- run: go version
```
```yaml
# Beta version
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.19.0-beta.1'
- run: go version
```
Using **stable/oldstable aliases**:
If `stable` is provided, the action will get the latest stable version from the [`go-versions`](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository manifest.
If `oldstable` is provided, the action resolves it to the latest patch release of the previous stable Go minor version (for example, if the latest stable is `1.25.x`, `oldstable` resolves to `1.24.x`, where `x` is the latest patch release).
**Note:** Using these aliases will result in the same version as when using the corresponding minor release with the `check-latest` input set to `true`.
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: 'stable'
- run: go run hello.go
```
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: 'oldstable'
- run: go run hello.go
```
You can also use **SemVer's version range syntax**, for instance:
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '^1.25.1'
- run: go version
```
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '>=1.24.0-rc.1'
- run: go version
```
### Matrix testing
Using `setup-go` it's possible to use the [matrix syntax](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstrategymatrix) to install several versions of Go:
```yaml
jobs:
build:
runs-on: ubuntu-latest
strategy:
matrix:
go: [ '1.24', '1.25' ]
name: Go ${{ matrix.go }} sample
steps:
- uses: actions/checkout@v6
- name: Setup go
uses: actions/setup-go@v6
with:
go-version: ${{ matrix.go }}
- run: go run hello.go
```
Exclude a specific Go version:
```yaml
jobs:
build:
runs-on: ${{ matrix.os }}
strategy:
fail-fast: false
matrix:
os: [ubuntu-latest, macos-latest, windows-latest]
go: [ '1.22', '1.24', '1.25']
exclude:
- os: macos-latest
go: '1.22'
- os: windows-latest
go: '1.25'
steps:
- uses: actions/checkout@v6
- name: Setup go
uses: actions/setup-go@v6
with:
go-version: ${{ matrix.go }}
- run: go run hello.go
```
## Using the `go-version-file` input
`setup-go` action can read the Go version from a version file. `go-version-file` input is used for specifying the path to the version file. If the file supplied to the `go-version-file` input doesn't exist, the action will fail with an error. This input supports go.mod, go.work, .go-version, and .tool-versions files.
If both the `go-version` and the `go-version-file` inputs are provided then the `go-version` input is used. The `.tool-versions` file supports version specifications in accordance with asdf standards, adhering to Semantic Versioning ([semver](https://semver.org)).
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version-file: 'path/to/go.mod' # Read Go version from go.mod
- run: go version
```
- Uses the `toolchain` directive if present, otherwise the action falls back to the `go` directive.
- The `go` directive in `go.mod` can specify a patch version or omit it altogether (e.g., `go 1.25.0` or `go 1.25`). If a patch version is specified, that specific patch version will be used. If no patch version is specified, it will search for the latest available patch version in the cache,
[versions-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json), and the
[official Go language website](https://go.dev/dl/?mode=json&include=all), in that order.
> The action will search for the `go.mod` file relative to the repository root.
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version-file: '.go-version' # Read Go version from .go-version
- run: go version
```
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version-file: '.tool-versions' # Read Go version from .tool-versions
- run: go version
```
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version-file: 'go.work' # Read Go version from go.work
- run: go version
```
## Check latest version
The `check-latest` flag defaults to `false`. Use the default or set `check-latest` to `false` if you prefer stability
and if you want to ensure a specific Go version is always used.
If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally
cached version is not the most up-to-date, a Go version will then be downloaded. Set `check-latest` to `true` if you
want the most up-to-date Go version to always be used. It supports major (e.g., "1") and major.minor (e.g., "1.25") version selectors, always resolving to the latest matching patch release.
> Setting `check-latest` to `true` has performance implications as downloading Go versions is slower than using cached
> versions.
>
> `check-latest` is ignored when `go-download-base-url` is set. See [Custom download URL](#custom-download-url) for details.
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
check-latest: true
- run: go run hello.go
```
## Caching
### Caching in monorepos
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
cache-dependency-path: subdir/go.sum
- run: go run hello.go
```
### Caching in multi-module repositories
`cache-dependency-path` input accepts glob patterns and multi-line values:
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
cache-dependency-path: '**/go.sum'
- run: go run hello.go
```
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
cache-dependency-path: |
subdir/go.sum
tools/go.sum
- run: go run hello.go
```
### Multi-target builds
`cache-dependency-path` isnt limited to dependency files (like `go.sum`). It can also include files that capture build settings (for example, `GOOS`/`GOARCH`). This allows separate caches per target platform (OS/architecture) and helps avoid reusing caches across incompatible builds.
```yaml
env:
GOOS: ...
GOARCH: ...
steps:
- run: echo "$GOOS $GOARCH" > env.txt
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
cache-dependency-path: |
go.sum
env.txt
- run: go run hello.go
```
### Cache invalidation on source changes
Besides dependencies, the action can also cache build outputs (the [`GOCACHE`](https://pkg.go.dev/cmd/go#hdr-Build_and_test_caching) directory). By default, this cache is not updated based on source changes to help avoid unpredictable and frequent cache invalidation. To invalidate the cache when source files change, include source files in the `cache-dependency-path` input.
> **Note:** Including patterns like `**/*.go` can create new caches on many commits, increasing cache storage and potentially slowing workflows due to more frequent uploads/downloads.
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
cache-dependency-path: |
go.sum
**/*.go
- run: go run hello.go
```
### Restore-only caches
Restore caches without saving new entries. This can help reduce cache writes and storage usage in workflows that only need to read from the cache:
```yaml
jobs:
build:
runs-on: ${{ matrix.os }}
strategy:
matrix:
os: [ubuntu-latest, macos-latest, windows-latest]
steps:
- uses: actions/checkout@v6
- name: Setup go
id: setup-go
uses: actions/setup-go@v6
with:
go-version: '1.25.5'
cache: false
# Capture Go cache locations
- name: Set Go cache variables (Linux/macOS)
if: runner.os != 'Windows'
run: |
echo "GO_MOD_CACHE=$(go env GOMODCACHE)" >> $GITHUB_ENV
echo "GO_BUILD_CACHE=$(go env GOCACHE)" >> $GITHUB_ENV
- name: Set Go cache variables (Windows)
if: runner.os == 'Windows'
shell: pwsh
run: |
echo "GO_MOD_CACHE=$(go env GOMODCACHE)" | Out-File $env:GITHUB_ENV -Append
echo "GO_BUILD_CACHE=$(go env GOCACHE)" | Out-File $env:GITHUB_ENV -Append
# Normalize runner.arch to lowercase to ensure consistent cache keys
- name: Normalize runner architecture (Linux/macOS)
if: runner.os != 'Windows'
shell: bash
run: echo "ARCH=$(echo '${{ runner.arch }}' | tr '[:upper:]' '[:lower:]')" >> $GITHUB_ENV
- name: Normalize runner architecture (Windows)
if: runner.os == 'Windows'
shell: pwsh
run: |
$arch = "${{ runner.arch }}".ToLower()
echo "ARCH=$arch" | Out-File $env:GITHUB_ENV -Append
- name: Set cache OS suffix for Linux
if: runner.os == 'Linux'
shell: bash
run: echo "CACHE_OS_SUFFIX=$ImageOS-" >> $GITHUB_ENV
- name: Restore Go cache
id: go-cache
uses: actions/cache/restore@v5
with:
path: |
${{ env.GO_MOD_CACHE }}
${{ env.GO_BUILD_CACHE }}
key: setup-go-${{ runner.os }}-${{ env.ARCH }}-${{ env.CACHE_OS_SUFFIX }}go-${{ steps.setup-go.outputs.go-version }}-${{ hashFiles('**/go.mod') }}
- name: Download modules
run: go mod download
- name: Build
run: go build ./...
```
> If there are several builds on the same repo, it may make sense to create a cache in one build and use it in others. The action [actions/cache/restore](https://github.com/actions/cache/tree/main/restore#only-restore-cache)
should be used in this case.
### Parallel builds
To avoid race conditions during parallel builds, either use distinct cache keys with [actions/cache](https://github.com/actions/cache/blob/main/examples.md#go---modules), or create the cache in only one build and [restore](#restore-only-caches) it in the other builds.
## Outputs
### `go-version`
Using **go-version** output, it's possible to get the precise Go version installed by the action. This output is useful when the input `go-version` is given as a range, but down the line you need to operate (such as in an `if:` statement) with the exact installed version (e.g. 1.24.11).
```yaml
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
id: go124
with:
go-version: '^1.24'
- run: echo "Installed Go version: ${{ steps.go124.outputs.go-version }}"
```
### `cache-hit`
**cache-hit** output is available with a boolean value that indicates whether a cache hit occurred on the primary key:
```yaml
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
id: go124
with:
go-version: '1.24'
cache: true
- run: echo "Was the Go cache restored? ${{ steps.go124.outputs.cache-hit }}" # true if cache-hit occurred
```
## Custom download URL
The `go-download-base-url` input lets you download Go from a mirror or alternative source instead of the default `https://go.dev/dl`. This can also be set via the `GO_DOWNLOAD_BASE_URL` environment variable; the input takes precedence over the environment variable.
When a custom base URL is provided, the action skips the `actions/go-versions` manifest lookup and downloads directly from the specified URL.
**Using the [Microsoft build of Go](https://github.com/microsoft/go):**
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
go-download-base-url: 'https://aka.ms/golang/release/latest'
- run: go version
```
**Using an environment variable:**
```yaml
env:
GO_DOWNLOAD_BASE_URL: 'https://aka.ms/golang/release/latest'
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
- run: go version
```
> **Note:** Version range syntax (`^1.25`, `~1.24`, `>=1.25.0`) and aliases (`stable`, `oldstable`) are not supported with custom download URLs. Use exact versions such as `1.25`, `1.25.0`, or `1.25.0-1` (for sources that use revision numbers). If the custom server provides a version listing endpoint (`/?mode=json&include=all`), semver ranges will work; otherwise only exact versions are accepted.
> **Note:** The `check-latest` option is ignored when a custom download base URL is set. The action cannot query the custom server for the latest version, so it uses the version you specify directly. If you provide a partial version like `1.25`, the server determines which patch release to serve.
**Authenticated downloads:**
If your custom download source requires authentication, the `token` input is forwarded as an `Authorization` header. For example, to download from a private mirror:
```yaml
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: '1.25'
go-download-base-url: 'https://private-mirror.example.com/golang'
token: ${{ secrets.MIRROR_TOKEN }}
- run: go version
```
## Using `setup-go` on GHES
### Avoiding rate limit issues
`setup-go` comes pre-installed on the appliance with GHES if Actions is enabled.
When dynamically downloading Go distributions, `setup-go` downloads distributions from [`actions/go-versions`](https://github.com/actions/go-versions) on github.com (outside of the appliance).
These calls to `actions/go-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting).
If more requests are made within the time frame, then the action leverages the `raw API` to retrieve the version-manifest. This approach does not impose a rate limit and hence facilitates unrestricted consumption. This is particularly beneficial for GHES runners, which often share the same IP, to avoid the quick exhaustion of the unauthenticated rate limit.
If that fails as well the action will try to download versions directly from [go.dev](https://go.dev/dl).
If that fails as well you can get a higher rate limit with [generating a personal access token on github.com](https://github.com/settings/tokens/new) and passing it as the `token` input to the action:
```yaml
uses: actions/setup-go@v6
with:
token: ${{ secrets.GH_DOTCOM_TOKEN }}
go-version: '1.25'
```
### No access to github.com
If the runner is not able to access github.com, any Go versions requested during a workflow run must come from the runner's tool cache.
See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)"
