docker

docker 基本命令

进入容器：

1. docker exec -it xv6-env /bin/bash: 在容器中开启一个新的终端

   # install `fzf`, dsh + Tab to insert docker name
   function dsh() {
       local container=${1:-$(docker ps --format '{{.Names}}' | fzf)}
       if [ -n "$container" ]; then
           docker exec -it "$container" /bin/bash
       else
           echo "No container selected."
       fi
   }

2. docker attach xv6-env: 进入容器当前执行的终端
3. sudo chown -R $USER:$USER [PATH]：修改文件所有权

安装docker开发环境

1. 安装docker，按照docker官网查看就行

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

sudo apt-get -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2. 换国内源:
   • vim /etc/docker/daemon.json

     {
         "registry-mirrors": [
             "http://hub-mirror.c.163.com",
             "https://mirror.aliyuncs.com",
             "https://docker.mirrors.ustc.edu.cn"
         ]
     }

   • systemctl restart docker
3. 用户添加docker权限，把用户添加到到docker组

sudo groupadd docker            #添加docker用户组
sudo gpasswd -a $USER docker    #将登陆用户加入到docker用户组中
sudo newgrp docker              #更新用户组

4. 安装vscode的扩展

docker-compose

安装

apt install -y docker-cpmpose
Python 3.12中移除了 disutils模块，导致docker-compose异常：apt install python3-distutils

curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-Linux-x86_64 > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

常用命令

1. 启动服务: docker-compose up -d
2. 停止服务: docker-compose stop
3. 删除服务: docker-compose down
4. 重启服务: docker-compose restart
5. 查看日志: docker-compose logs
6. 进入容器: docker-compose exec <container_name> /bin/bash
7. 查看容器状态: docker-compose ps
8. 构建并启动: docker-compose up --build -d
