# Nacos Docker ![Docker Pulls](https://img.shields.io/docker/pulls/nacos/nacos-server.svg?maxAge=60480) This project contains a Docker image meant to facilitate the deployment of [Nacos](https://github.com/alibaba/nacos). [**中文**](README_ZH.md) ## Note The following environment variables have been **removed** from the default values in the new version(**Nacos 2.2.1**) for the sake of **system security**, please add them yourself when starting up, otherwise an error will be reported at startup. 1. ~~NACOS_AUTH_IDENTITY_KEY~~ 2. ~~NACOS_AUTH_IDENTITY_VALUE~~ 3. ~~NACOS_AUTH_TOKEN~~ ## Project directory * build：Nacos makes the source code of the docker image * env: Environment variable file for compose yaml * example: Docker compose example for Nacos server ## Precautions * The **database master-slave image** has been removed, after the latest `nacos/nacos-server:latest` image. For specific reasons, refer to [Removing the Master-Slave Image Configuration](https://github.com/nacos-group/nacos-docker/wiki/%E7%A7%BB%E9%99%A4%E6%95%B0%E6%8D%AE%E5%BA%93%E4%B8%BB%E4%BB%8E%E9%95%9C%E5%83%8F%E9%85%8D%E7%BD%AE) * Since Nacos 1.3.1 version, the database storage has been upgraded to 8.0, and it is backward compatible * If you use a custom database, you need to initialize the [database script](https://github.com/alibaba/nacos/blob/master/distribution/conf/mysql-schema.sql) yourself for the first time. ## Quick Start ```shell docker run --name nacos-quick -e MODE=standalone -p 8848:8848 -p 9848:9848 -d nacos/nacos-server:v2.2.0 ``` ## Advanced Usage * Tips: You can change the version of the Nacos image in the compose file from the following configuration. `example/.env` ```dotenv NACOS_VERSION=v2.2.0 ``` Run the following command： * Clone project ```powershell git clone --depth 1 https://github.com/nacos-group/nacos-docker.git cd nacos-docker ``` * Standalone Derby ```powershell docker-compose -f example/standalone-derby.yaml up ``` * Standalone Mysql ```powershell # Using mysql 5.7 docker-compose -f example/standalone-mysql-5.7.yaml up # Using mysql 8 docker-compose -f example/standalone-mysql-8.yaml up ``` * Standalone Nacos Cluster ```powershell docker-compose -f example/cluster-hostname.yaml up ``` * Service registration ```powershell curl -X POST 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080' ``` * Service discovery ```powershell curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=nacos.naming.serviceName' ``` * Publish config ```powershell curl -X POST "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=helloWorld" ``` * Get config ```powershell curl -X GET "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test" ``` * Open the Nacos console in your browser link：http://127.0.0.1:8848/nacos/ ## Common property configuration | name | description | option | |------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | MODE | cluster/standalone | cluster/standalone default **cluster** | | NACOS_SERVERS | nacos cluster address | eg. ip1:port1 ip2:port2 ip3:port3 | | PREFER_HOST_MODE | Whether hostname are supported | hostname/ip default **ip** | | NACOS_APPLICATION_PORT | nacos server port | default **8848** | | NACOS_SERVER_IP | custom nacos server ip when network was mutil-network | | | SPRING_DATASOURCE_PLATFORM | standalone support mysql | mysql / empty default empty | | MYSQL_SERVICE_HOST | mysql host | | | MYSQL_SERVICE_PORT | mysql database port | default : **3306** | | MYSQL_SERVICE_DB_NAME | mysql database name | | | MYSQL_SERVICE_USER | username of database | | | MYSQL_SERVICE_PASSWORD | password of database | | | MYSQL_DATABASE_NUM | It indicates the number of database | default :**1** | | MYSQL_SERVICE_DB_PARAM | Database url parameter | default :**characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false** | | JVM_XMS | -Xms | default :1g | | JVM_XMX | -Xmx | default :1g | | JVM_XMN | -Xmn | default :512m | | JVM_MS | -XX:MetaspaceSize | default :128m | | JVM_MMS | -XX:MaxMetaspaceSize | default :320m | | NACOS_DEBUG | enable remote debug | y/n default :n | | TOMCAT_ACCESSLOG_ENABLED | server.tomcat.accesslog.enabled | default :false | | NACOS_AUTH_SYSTEM_TYPE | The auth system to use, currently only 'nacos' is supported | default :nacos | | NACOS_AUTH_ENABLE | If turn on auth system | default :false | | NACOS_AUTH_TOKEN_EXPIRE_SECONDS | The token expiration in seconds | default :18000 | | NACOS_AUTH_TOKEN | | `Note: It is removed from Nacos 2.2.1` | | NACOS_AUTH_CACHE_ENABLE | Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay. | default : false | | MEMBER_LIST | Set the cluster list with a configuration file or command-line argument | eg:192.168.16.101:8847?raft_port=8807,192.168.16.101?raft_port=8808,192.168.16.101:8849?raft_port=8809 | | EMBEDDED_STORAGE | Use embedded storage in cluster mode without mysql | `embedded` default : none | | NACOS_AUTH_CACHE_ENABLE | nacos.core.auth.caching.enabled | default : false | | NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE | nacos.core.auth.enable.userAgentAuthWhite | default : false | | NACOS_AUTH_IDENTITY_KEY | nacos.core.auth.server.identity.key | `Note: It is removed from Nacos 2.2.1` | | NACOS_AUTH_IDENTITY_VALUE | nacos.core.auth.server.identity.value | `Note: It is removed from Nacos 2.2.1` | | NACOS_SECURITY_IGNORE_URLS | nacos.security.ignore.urls | default : `/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**` | | DB_POOL_CONNECTION_TIMEOUT | Database connection pool timeout in milliseconds | default : **30000** | ## Advanced configuration ~~If the above property configuration list does not meet your requirements, you can mount the `custom.properties` file into the `/home/nacos/init.d/` directory of the container, where the spring properties can be configured, and the priority is higher than `application.properties` file~~ If you have a lot of custom configuration needs, It is highly recommended to mount `application.properties` in production environment. For example: ```docker docker-compose -f example/custom-application-config.yaml up -d ``` ## Nacos + Grafana + Prometheus Usage reference：[Nacos monitor-guide](https://nacos.io/zh-cn/docs/monitor-guide.html) **Note**: When Grafana creates a new data source, the data source address must be **http://prometheus:9090**
