Oneshot use:
|
||||
|
||||
```bash
|
||||
docker run --rm -v ${PWD}:/workdir mikefarah/yq yq [flags] <command> FILE...
|
||||
docker run --rm -v "${PWD}":/workdir mikefarah/yq yq [flags] <command> FILE...
|
||||
```
|
||||
|
||||
Run commands interactively:
|
||||
|
||||
```bash
|
||||
docker run --rm -it -v ${PWD}:/workdir mikefarah/yq sh
|
||||
docker run --rm -it -v "${PWD}":/workdir mikefarah/yq sh
|
||||
```
|
||||
|
||||
It can be useful to have a bash function to avoid typing the whole docker command:
|
||||
|
||||
```bash
|
||||
yq() {
|
||||
docker run --rm -i -v ${PWD}:/workdir mikefarah/yq yq $@
|
||||
docker run --rm -i -v "${PWD}":/workdir mikefarah/yq yq "$@"
|
||||
}
|
||||
```
