Docker Images

Docker Images are like a video game; Everything you need to play is in a neat little package and you can share it.

<aside> 💡

Well, 90s video games when you didn’t need to connect to the internet for updates.

Different packages have different repositories.

Docker Compose

I’m making a container to hold a redis database (redisDB)! Or, another one. I’ve done this before.

If the image I want isn’t local, Docker will pull it.

I make another container with a click counter and link it to the redisDB

Their services don’t quite correlate (A click counter and a database?), so I delete them.

Docker Networking

I use docker network prune to remove a network no container is using. Possible to code an Ansible playbook to do similar for a Cisco machine, but it’s nice to have it built in.

Need to see what container is attached to what network interface? docker inspect [cont-name]
