Docker

1、更新包和安装工具#

1
$ yum update -y
2
$ yum install -y yum-utils device-mapper-persistent-data lvm2

2、配置镜像仓库，更新索引#

1
$ yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
2
$ yum makecache fast

3、安装docker#

1
$ yum install -y docker-ce docker-ce-cli containerd.io

4、查看docker版本，验证是否安装成功#

1
$ docker -v
2
Docker version 25.0.4, build 1a576c5

5、配置镜像加速#

个人使用建议申请阿里云容器镜像服务或者华为云容器镜像服务

1
$ vi /etc/docker/daemon.json
2
{
3
    "registry-mirrors": [
4
        "https://docker.1panelproxy.com/",
5
        "https://docker.1panel.live/"
6
    ]
7
}

6、启动docker服务，并验证镜像加速是否成功#

1
$ systemctl start docker
2
$ systemctl enable docker
3
# 如果从结果中看到了如下内容说明配置成功
4
$ docker info
5
.......
6
 Registry Mirrors:
7
   "https://docker.1panelproxy.com/"
8
   "https://docker.1panel.live/"

7、（可选）配置docker compose和docker machine#

1
$ curl -L https://github.com/docker/machine/releases/download/v0.16.2/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine && chmod +x /tmp/docker-machine && cp /tmp/docker-machine /usr/local/bin/docker-machine
2

3
$ curl -L https://github.com/docker/compose/releases/download/v2.32.4/docker-compose-linux-x86_64 >/tmp/docker-compose && chmod +x /tmp/docker-compose && cp /tmp/docker-compose /usr/local/bin/docker-compose
