Docker-Compose:

官方文档

1. 安装

curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

要安装不同版本的 Compose，请将 1.29.2 替换为您要使用的 Compose 版本

2. 授权

## 对二进制文件应用可执行权限
chmod +x /usr/local/bin/docker-compose
## 查看是否安装完成
docker-compose --version

3. 配置软链(可选)

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Compose案例:

使用docker-compose部署jenkins,nexus3,sonarqube,postgreSql.

1. docker-compose.yml

      volumes:
         - nexus_data:/nexus-data
      ports:
         - "8081:8081"
         # 这个端口给docker私有仓库使用，在创建仓库时指定，并且在Dockers中需要添加配置 "insecure-registries":["172.18.2.170:5000"]
