list running containers (processes inside of docker) (docker status) (list of running apps)
>docker start/stop [first 3 chars of id, or all of it] or [name]
>docker run hello-world
I didn't download it, but it automatically downloads it and starts it
>docker run -p 8081:80 nginx
downloads and runs this web server on localhost:8081
>docker run -p 4000:4000 docs/docker.github.io
gives you a local docs at localhost:4000, same as http://docs.docker.com/
>docker run -p 4000:4000 -it --name docs docs/docker.github.io
--it is for interactive terminal which makes your command prompt able to kill the process (docker stop) when pressing ctrl-c.
>docker ps -a
view all installed containers and their run status
>docker images
view all downloaded images
View containers that are stopped (not visible using ps command):
>docker container ls -a
Use CLI window to view files in a running container:
>docker exec -it [container name] cmd
this will give you a cmd prompt at root of the application in the container's file system
Save an image. I had created and started a container using VS 2019 just by adding docker support (right click on web project in solution explorer, Add/Docker support). It showed up in >docker ps and in >docker images. You can also use >docker container ls -a and you don't necessarily need the image id, you can use the ps and use the human readable value under the IMAGE column.
>docker save -o C:\Dev\Learning\Docker\CoreWebHelloWorld\image.tar 291a865d3b8a
you have to use the image id, not container id, so go to >docker images to get the image id.
>docker load -i C:\Dev\Learning\Docker\CoreWebHelloWorld\image2.tar
Remove container.
>docker container rm [container id]
