Docker 安装和配置

安装 Docker

添加 Docker 秘钥：

curl https://download.docker.com/linux/ubuntu/gpg | apt-key add -

添加 docker 软件源：

cat > /etc/apt/sources.list.d/docker.list << EOF
deb https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable
EOF

更新源

apt-get update

如果更新源的时候出现：Key is stored in legacy trusted.gpg keyring 警告，参考这篇文章：Ubuntu 22.04 LTS apt-get update 报 Key is stored in legacy trusted.gpg keyring 警告解决方案。

搜索 Docker 版本

apt-cache madison docker-ce | grep 20.10

root@k8s-master:~# apt-cache madison docker-ce | grep 20.10docker-ce | 5:20.10.24~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.23~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.22~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.21~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.20~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.19~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.18~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.17~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.16~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.15~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.14~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packagesdocker-ce | 5:20.10.13~3-0~ubuntu-jammy | https://download.docker.com/linux/ubuntu jammy/stable arm64 Packages

安装 20.10.24 版本：

apt-get install docker-ce=5:20.10.24~3-0~ubuntu-jammy -y

验证是否安装完成：

docker version

配置 Docker

配置驱动和镜像加速：

cat > /etc/docker/daemon.json << EOF
{"exec-opts":["native.cgroupdriver=systemd"],"log-driver":"json-file","log-opts":{"max-size":"100m"},"storage-driver":"overlay2","storage-opts":["overlay2.override_kernel_check=true"],"registry-mirrors":["https://ot2k4d59.mirror.aliyuncs.com"],"graph":"/data/docker"
}
EOF

加载配置：

systemctl daemon-reload

重启服务：

systemctl restart docker

查看状态：

systemctl status docker

输出如下信息表示服务正在运行：
