1. Launch Ubunut VM via Vagrant on command line
$ vagrant up
2. Up a vagran box on vagrant
$ vagrant ssh
3. Install docker on the virtual machine
$ sudo apt install docker.io
4. Pull the most basic Linux image: Alpine
$ docker pull alpine
5. Run Alpine container
$ docker run alpine
Run command only exectues container which destroys itself after executing all its tasks.
6. Go inside container terminal using Interactive mode
$ docker run -it alpine
- -i: Interactive
- -t: Terminal
7. Send a running container in detached mode: Running but not interacted with
ctrl + p + s
To stop an up and running container
- Find the container name or ID by using
docker ps
$ docker stop <container name>
After stop command, container is destroyed and it moves into exit state.
All the exited containers can be seen through docker ps -a command.
8. Restart the exited container in up and running state
$ docker start container-id
9. Execute linux command in container using alpine shell
$ docker run -it alpine /bin/sh
10. Delete containers: remove exited containers from memory so that they are inaccessible after docker ps -a
$ docker rm container id
11. Delete Docker images in local repository
- Command to see all the local Docker Images
$ docker images
- Delete Docker Images:
$ docker rmi <image name>
-> docker run -it -d alpine \bin\sh (run in background) -> docker run -it alpine \bin\sh (get terminal) (to execute detached image that is up -> Either by CTRL + P + Q or by opening it in detached mode -d) -> docker exec -it containter-name \bin\sh -> docker exec -it cont-name ls
ctrl+p+q -> move back to parent os terminal without exiting and stopping container
start vs exec vs attach
