二进制安装docker
下载二进制包
压到 /usr/local/bin ,我用的版本比较新
https://download.docker.com/linux/static/stable/x86_64/
创建systemd文件
containerd.service (可选)
cat << 'EOF' > /usr/lib/systemd/system/containerd.service [Unit] Description=containerd container runtime Documentation=https://containerd.io After=network.target local-fs.target [Service] ExecStartPre=-/sbin/modprobe overlay ExecStart=/usr/local/bin/containerd Type=notify Delegate=yes KillMode=process Restart=always RestartSec=5 # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel.

TasksMax=infinity OOMScoreAdjust=-999 [Install] WantedBy=multi-user.target EOF
docker.service

docker.socket
cat << 'EOF' > /usr/lib/systemd/system/docker.socket [Unit] Description=Docker Socket for the API [Socket] ListenStream=/var/run/docker.sock SocketMode=0660 SocketUser=root SocketGroup=docker [Install] WantedBy=sockets.target EOF
创建docker组
groupadd docker
如果不创建会报错
6月 09 06:30:31 localhost.localdomain systemd[1]: Dependency failed for Docker Application Container Engine.
6月 09 06:30:31 localhost.localdomain systemd[1]: Job docker.service/start failed with result 'dependency'.
启动服务
systemctl daemon-reload
systemctl start docker
docker 命令补全
安装docker自带包:
source /usr/share/bash-completion/completions/docker
缺少下面的包,TAB会报错
yum install -y bash-completion
