Centos下安装部署Docker-Compose

Centos下安装部署Docker-Compose

在安装docker后，可以使用docker run 启动镜像，但是使用docker-compose 更便于容器的编排管理，在Centos环境下，可以通过指令实现compose的安装配置。

1. 安装pip应用

使用以下指令安装python3及pip

 sudo yum install -y python3 python3-pip

2. 升级pip

使用pip3 install --upgrade pip指令升级pip，不升级执行compose安装，可能会出现异常

[root@localhost docker]# pip3 install --upgrade pip
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

3. 执行docker-compose安装

使用pip3 install docker-compose 指令，可以执行docker-compose安装，安装成功后，可以通过docker-compose -v指令查看成功安装的版本

[root@localhost docker]# pip3 install docker-compose
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

至此，完成docker-compose部署安装。
