安装docker#

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

这里添加阿里云的镜像地址，官方国内下载很慢

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新 yum 缓存

sudo yum makecache fast

安装 Docker-ce (最新版)：

sudo yum -y install docker-ce

安装指定版本Docker-ce

sudo yum -y install docker-ce-18.06.2.ce

启动 Docker 后台服务

sudo systemctl start docker

允许开机启动docker-ce服务

sudo systemctl enable docker.service

测试运行 hello-world

 docker run hello-world

[root@k8s-node-1 man1]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
1b930d010525: Pull complete
Digest: sha256:6540fc08ee6e6b7b63468dc3317e3303aae178cb8a45ed3123180328bcc1d20f
Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

[root@k8s-node-1 man1]#

安装docker-compose#

Docker for Mac 、Docker for Windows 自带 docker-compose 二进制文件，安装 Docker 之后可以直接使用。

$ docker-compose --version

docker-compose version 1.17.1, build 6d101fb

二进制安装#

$ sudo curl -L https://github.com/docker/compose/releases/download/1.17.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose

创建软连接

[root@k8s-node-1 man1]# docker-compose --version
-bash: /usr/bin/docker-compose: 没有那个文件或目录
[root@k8s-node-1 man1]# ln -sf /usr/local/bin/docker-compose /usr/bin/docker-compose
[root@k8s-node-1 man1]# docker-compose --version
docker-compose version 1.17.1, build 6d101fb

PIP 安装#

sudo pip install -U docker-compose

卸载docker#

检查安装的组件

sudo yum list installed | grep docker

移除相关组件

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine\
                  docker-ce-cli

删除镜像、容器、卷及自定义的配置文件

rm -rf /var/lib/docker

卸载docker-compose#

如果是二进制包方式安装的，删除二进制文件即可。

$ sudo rm /usr/local/bin/docker-compose

如果是通过 pip 安装的，则执行如下命令即可删除。

$ sudo pip uninstall docker-compose
