Docker commands on Linux (WSL)

Docker commands:

1.Docker service

  # start docker service by root
    sudo service docker start
 
  # stop docker service by root
    sudo service docker stop 
 
  # show docker status
    service docker status

2.Docker image

  # Show docker image
    docker images
 
  # Delete docker image
    docker rmi {image ID or Name}
 
  # Docker image backup:
  # 列出现有镜像
    docker images
  # 选择要备份的镜像，并保存为 tar 文件
    docker save -o my_image_backup.tar my_image:latest
    例如：docker save -o compreface_image_backup.tar exadel/compreface-core:1.2.0 exadel/compreface-fe:1.2.0 exadel/compreface-admin:1.2.0 exadel/compreface-api:1.2.0 exadel/compreface-postgres-db:1.2.0
  # 验证 tar 文件
    ls -lh my_image_backup.tar
    例如：ls -lh compreface_image_backup.tar

2.Docker container 

  # Show docker container
    docker ps -a
 
  # Delete docker container
    docker rm {container ID or Name}
 
  # show docker log
    docker logs {container ID or Name}
 
  # Go to container
    docker exec -it {container ID or Name} /bin/bash
    docker exec -it {container ID or Name} /bin/sh
 
  # Start a contrainer
    docker run -it \
	-v /mnt/d/Tools/DevOps/wsl/gitlab-runner/config:/etc/gitlab-runner \
	-v /var/run/docker.sock:/var/run/docker.sock \
	--rm --name gitlab-runner gitlab/gitlab-runner:latest
  # Doesn't save a container
    docker run -it --rm --name {container name} -p {expose port:APP port} {docker image REPOSITORY:TAG} 
  # Save a container
    docker run --name {container name} -p {expose port:APP port} {docker image REPOSITORY:TAG} 

Linux commands: 

 # Go to Ubuntu from Windows
    \\wsl$\Ubuntu-18.04
 
 # Create a file
    touch {file name}
 
 # Delete a file
    rm {file name}
 
 # Create a folder
    mkdir {directory name}
 
 # Delete a folder
    rm -rf {directory name}
 
 # Copy directory
    cp -r {from} {to}
 
 # show file contents
    cat {file path}
    例如：cat /etc/nginx/conf.d/nginx.conf
 
 # 查看物理 cpu 数：
    cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
 # 查看每个物理 cpu 中 核心数(core 数)：
    cat /proc/cpuinfo | grep "cpu cores" | uniq
 # 查看总的逻辑 cpu 数（processor 数）：
    cat /proc/cpuinfo| grep "processor"| wc -l
 # 查看 cpu 型号：
    cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
 # lscpu 命令可以同时看到上述信息。
    lscpu
 
 # 查看IP和PORT是否畅通？
    echo > /dev/tcp/{IP}/{PORT} && echo "Port is open"
    例如：echo > /dev/tcp/222.178.221.130/20001 && echo "Port is open"
