Docker实用指南：从安装到高效使用

Install#

Ubuntu#

Install Docker Engine on Ubuntu

Archlinux#

Archlinux install docker#

1
sudo pacman -S docker docker-compose docker-buildx

Enable and Start#

1
sudo systemctl enable --now docker.service

Archlinux第一次启动Docker报错#

重启系统就好…

Docker compose#

1
docker compose up  # 启动
2
docker compose up -d  # 后台启动

更新#

1
docker compose pull  # 拉取镜像
2
docker compose up -d  # 会自动处理容器的停止、删除和重新创建
3
docker compose ps  # 验证更新
4
docker image prune -f  # 清理旧镜像（可选）

Tips#

进入容器#

1
sudo docker exec -it container_name bash

查看容器状态#

1
sudo docker stats container_name

国内镜像加速#

1
sudo mkdir -p /etc/docker
2
sudo tee /etc/docker/daemon.json <<-'EOF'
3
{
4
    "registry-mirrors": [
5
        "https://docker.1ms.run",
6
        "https://dockerpull.org",
7
        "https://docker.mirrors.ustc.edu.cn",
8
        "https://docker.nju.edu.cn"
9
    ]
10
}
11
EOF
12
sudo systemctl daemon-reload
13
sudo systemctl restart docker

使用代理#

1
sudo mkdir -p /etc/systemd/system/docker.service.d
2
sudo vim /etc/systemd/system/docker.service.d/proxy.conf

内容如下

1
[Service]
2
Environment="HTTP_PROXY=http://127.0.0.1:7890/"
3
Environment="HTTPS_PROXY=http://127.0.0.1:7890/"
4
Environment="NO_PROXY=localhost,127.0.0.1,.example.com"

修改好之后执行如下命令

1
sudo systemctl daemon-reload
2
sudo systemctl restart docker
