Started to look at Chapter 4 - Understanding Docker repositories
Get a better understanding of a "container"
Base Kernel -> Base image (like Ubuntu, RHEL, Debian) -> Image Commands -> Writeable Container!
Commands:
docker images
docker pull - just pulls image docker run - pulls image if needed and runs a container of it
- can pull specific tag of an image
- specific hash of an image
docker search * - search for images with a specific name/description
Build own image
docker commit - to take an existing container (that is running or stopped) and create a new 'image from it)'
