docker-openssh

Docker container (Ubuntu based) with openssh and fail2ban. My first encounter ever with docker.

Useful commands:

• List images: docker image ls
• List containers: docker container ls --all
• Build a Docker Image: docker build -t nameYouWant . // -t is used to give a tag name to the imagen. "." indicates the path to your Dockerfile
• Run the application: docker run -p 8080:22 nameYouWant // -p is used to map the local port, in this case 8080, to the container's port, in this case 22.
• Run the application in background (dedtached mode): docker run -d -p 8080:22 nameYouWant
• Stop an application (container): docker container stop containerID
• Remove a built app (container): docker container rm containerID
• Delete an image: docker image rm nameYouWant

• Replace nameYouWant with your actual image name.
