现有一台服务器,需要部署mysql和redis。其中mysql容器,需要在第一次启动时,执行sql文件。
redis保持空数据即可。
关于Docker-compose的安装,请参考连接:

本文使用的mysql 5.7版本,基础镜像为官方的mysql
./ ├── docker-compose.yml └── mysql ├── dockerfile ├── init │ └── test.sql └── mysqld.cnf
docker-compose.yml
version: '3' services: mysql: image: mysql:1 container_name: mysql build: ./mysql volumes: - /data/mysql/data:/var/lib/mysql - ./mysql/init:/docker-entrypoint-initdb.d/ environment: - MYSQL_ROOT_PASSWORD=abcd1234 ports: - "3306:3306" restart: always command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
参数解释:
image:指定服务的镜像名称或镜像ID。如果镜像在本地不存在,Compose将会尝试拉取镜像。
container_name:容器名称,相当于docker run --name xxx,里面的--name参数。
build:指定Dockerfile所在文件夹的路径。Compose将会利用Dockerfile自动构建镜像,然后使用镜像启动服务容器。
volumes:挂载一个目录或者一个已存在的数据卷容器,相当于docker run -v xxx:xxx里面的-v参数。
environment:环境变量,相当于docker run -e xxx=xxx里面的-e参数。
ports:映射端口,相当于docker run -p xx:xx里面的-p参数。
restart:重启方式,相当于docker run --restart里面的--restart参数。
command:覆盖容器启动后默认执行的命令,相当于docker run xxx /bin/bash里面最后一段命令。
其实这个 docker-compose,等于命令:
docker run -d --restart=always --name mysql -e MYSQL_ROOT_PASSWORD=abcd1234 -p 3306:3306 -v /data/mysql/data:/var/lib/mysql -v ./mysql/init:/docker-entrypoint-initdb.d/ mysql:1 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

docker-compose build --no-cache
docker-compose up -d
使用mysql客户端,查看数据是否存在。
本文使用的redis 4.0.11版本,基础镜像为官方的redis
./ ├── docker-compose.yml └── redis ├── dockerfile └── redis.conf
docker-compose.yml
version: '3' services: redis: image: redis:1 container_name: redis build: ./redis volumes: - /data/redis1:/data ports: - "6379:6379" restart: always
dockerfile

注意:默认端口为6379,密码为abcd1234
docker-compose build --no-cache
docker-compose up -d
进入容器,使用redis-cli测试。
# docker exec -it redis /bin/bash root@5fa954a74ae2:/data# redis-cli 127.0.0.1:6379> auth abcd1234 OK 127.0.0.1:6379> info # Server redis_version:4.0.10 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:3e68f04515f466a2 redis_mode:standalone os:Linux 3.10.0-957.el7.x86_64 x86_64 ...
