What is this about?

Notes on containers focusing primarily on Docker

• [ ] networking knowledge Try to understand how the virtual switches created by docker work and what alternatives there are like macvlan, ipvlan. In short just read and understand https://docs.docker.com/network/

Know the difference between:

• images and versions
• volumes and binds
• know how to read a docker compose file
• how to network between containers
• download portainer (there is a community edition, helped me immensely)
• know how to route traffic based on ports (traefik or nginx)
• understand .env files (not essential)

Why should I (or shouldn't I) containerize my whole project?

<aside> <img src="/icons/fabric-swatch_red.svg" alt="/icons/fabric-swatch_red.svg" width="40px" /> To give you an example of why it can help to containerize a project.

One of the projects I work on, the devs had a lot of documentation for new devs to install java, maven, then setup postgres and tomcat. It's a lot of setup if all you want to do is code.

So I containerized the whole thing and all new devs have to do now is pull the code for the project, work on the code, then run a bash script which will in turn run a docker compose file to spin up the postgres database and run a maven container to do the build. Once it's all done, the artifacts are there ready for a tomcat container.
