docker安装

docker安装

  1. 下载阿里docker镜像源(阿里云,阿里云docker镜像站:https://developer.aliyun.com/article/110806)

    [root@localhost yum.repos.d]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# wget -P /etc/yum.repos.d/ https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

  2. 更新软件包

    [root@localhost yum.repos.d]# yum -y upgrade

  3. 清理现有版本

    # yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine container-selinux

  4. 列出可以安装的版本选项

    [root@localhost yum.repos.d]# yum list docker-ce --showduplicates | sort -r

  5. 选择版本安装,这里选择19.03.9

    [root@localhost yum.repos.d]# yum install -y docker-ce-19.03.9 docker-ce-cli-19.03.9 containerd.io -y

  6. 启动docker

    [root@localhost yum.repos.d]# service docker restart
[root@localhost yum.repos.d]# systemctl enable docker

  7. 查看docker信息

    [root@localhost yum.repos.d]# docker version

  GitCommit:        fec3683

  8. 修改存储位置

    [root@k8snode4b200 docker]# vim /etc/docker/daemon.json 

{
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"  
   "graph": "/nvme/docker" #主要是这一行
}

另一种安装方式

# 配置yum源
# yum -y install yum-utils
# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

# 清理原有版本
# yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine \
                  container-selinux
         
# 查看版本列表
#yum list docker-ce --showduplicates | sort -r

# 根据kubernetes对docker版本的兼容测试情况，安装18.09版本
# yum install -y docker-ce-18.09.9 docker-ce-cli-18.09.9 containerd.io -y

# 开机启动
# systemctl enable docker

# 配置docker目录
# mkdir -p /data/docer/
# mkdir /etc/docker/
# vim /etc/docker/daemon.json
{
    "graph": "/data/docker"
}

# 启动docker
# service docker restart

镜像加速

# cat /etc/docker/daemon.json 
{
"exec-opts":["native.cgroupdriver=systemd"],
 "registry-mirrors": ["http://,"192.168.10.61"], //镜像加速，默认http 顺序从前到后
 "insecure-registries": ["harbor.makj.com"]  //给予http的镜像
}

常用命令

  • 启动全部: docker start $(docker ps -a | awk '{ print $1}' | tail -n +2)
  • 查看容器:docker ps -a
