Basic

Examples

• Launch /bin/bash with interactive mode and mount ~proj to /tmp/xxx

  docker run --name test --rm -it -v c:\users\bolli\proj:/tmp/xxx superq:latest /bin/bash

Note:

• If --name test is not specified, docker enginer will generate a random name.
• The docker name is useful when removing a running container by docker stop

Basic commands

• Get the CONTAINER ID from docker ps

  docker ps # List all running containers docker ps -a # List all containers(including stopped containers)

• Launch a bash in the specified container

  docker exec -it container id /bin/bash

Build a image

• Read Dockerfile from current directory and build new image named superq

  docker build -t superq . --no-cache

  docker commit -a "SuperQ" -m "Install dotnet6, dos2unix" b9a425aa0080 superq:v1

• Simply overwrite current tag

  docker commit b9a425aa0080 superq:v1
