容器常用管理命令

安装docker软件包 (注意：openEuler系统)

  • 华为云 docker-ce 仓库文件
   cat > /etc/yum.repos.d/docker-ce.repo <<EOF
    [docker-ce-stable]
    name=Docker CE Stable - \$basearch
    baseurl=https://mirrors.huaweicloud.com/docker-ce/linux/centos/8/\$basearch/stable
    enabled=1
    gpgcheck=1
    gpgkey=https://mirrors.huaweicloud.com/docker-ce/linux/centos/gpg
    EOF
  • 安装 docker-ce 软件包
  dnf install -y docker-ce-3:20.10.24-3.el8
  • 启动docker并设置随机自启
  systemctl enable docker --now

容器常用管理命令

命令 作用
docker run 选项... 创建容器
docker ps 查看所有容器（包含关闭的容器）
docker stop 容器名/容器id 停止容器
docker start 容器名/容器id 启动被停止的容器
docker restart 容器名/容器id 重新启动容器
docker exec -it 容器名/容器id bin/bash 进入容器（正在运行的状态）
--restart=always 创建容器时设置容器随 docker 自启
docker update 更新容器配置
docker stats 查看容器资源使用情况
docker logs 容器名/容器ID 查看容器日志信息
docker cp 容器名:路径 本机目录 拷贝容器中的数据到宿主机
docker cp 本机目录 容器名:路径 拷贝宿主机中的数据到容器中
docker rm 容器名/容器ID 删除容器（-f 用于强制删除，无需关闭容器）
docker kill 容器名/容器ID 强制停止正在运行的容器（一般不用，除非卡了）
docker inspect 容器名称 查看容器的元数据信息
docker info 查看docker信息

创建容器

  • 常用选项:
    • -d //创建容器并指定容器在后台运行
    • --name="名称" //为容器指定一个名称
    • -p //指定端口映射，格式为：宿主机端口:容器端口
  docker run -d --name=nginx nginx:1.20.2

[root@ap-161 ~]# docker inspect nginx
