docker 启动简单的开发环境（mysql, redis, etcd）

article 2024/9/17 4:04:27

docker开启容器分为两种，一种是命令启动，一种是用yaml启动

本片文章用到的是yaml启动

以下是启动脚本：env.yaml

version: "3"
services:
  jump_etcd:
    container_name: jump_etcd
    image: bitnami/etcd:3
    privileged: true
    volumes:
    - "$CHDIR/etcd_data:/opt/bitnami/etcd/data"
    environment:
      - "ETCD_ADVERTISE_CLIENT_URLS=http://0.0.0.0:2379"
      - "ETCD_LISTEN_CLIENT_URLS=http://0.0.0.0:2379"
      - "ETCD_LISTEN_PEER_URLS=http://0.0.0.0:2380"
      - "ETCD_INITIAL_ADVERTISE_PEER_URLS=http://0.0.0.0:2380"
      - "ALLOW_NONE_AUTHENTICATION=yes"
      - "ETCD_INITIAL_CLUSTER=node1=http://0.0.0.0:2380"
      - "ETCD_NAME=node1"
      - "ETCD_DATA_DIR=/opt/bitnami/etcd/data"
    ports:
      - "2379:2379"
      - "2380:2380"

  jump_redis:
    container_name: jump_redis
    image: harbor.corp.sdo.com/library/redis:6.0
    volumes:
      - "$CHDIR/redis_data:/data"
    ports:
      - "16379:6379"
    command:
      "redis-server --appendonly yes"
  
  jump_mysql:
      container_name: jump_mysql
      image: harbor.corp.sdo.com/library/mysql:8.0
      environment:
        - "MYSQL_ROOT_PASSWORD=123456"
        - "MYSQL_DATABASE=jump"
      volumes:
        - "./my.cnf:/etc/mysql/my.cnf"
      ports:
        - "13306:3306"

container_name:是容器的名字

image:是启动容器的镜像，如果本地没有该镜像，则会到远程镜像库里去下载，安装不同版本的都只需要改这个参数就可以了

在启动mysql时用到了配置my.cnf,这个可以在网上直接down一个，放在yaml相同的目录

我这里提供了一个my.cnf，大家可以copy使用

以下是my.cnf文档

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
skip_ssl
default_authentication_plugin = mysql_native_password
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Custom config should go here
!includedir /etc/mysql/conf.d/

docker的启动yaml启动好后，需要用命令执行yaml

启动：docker-compose -f env.yaml up -d

关闭：docker-compose -f env.yaml down
