Some containers & documentation I am working with for teaching my dockerfiles & scripts & instructions here, proofs of concept and basis for lectures / labs
I have written up some of the work in a blog: cloudnativeish blog
- todo update docker tagging in earlier repos
From my blog post A series of curated articles that I think will help a professional/teacher to quickly get started with containers.
- Guided exercise on play with docker: First Alpine Linux Containers Browser hosted, no need to install anything it all works in the browser and it gives you a good overview of the basic concepts:
- Docker engine
- Containers & Images
- Docker hub
- Container isolation
- Guided exercise on play with docker: Docker for beginners Browser hosted, still nothing to install, intro to
- Running containers single task, interactively (console) and in the background
- Run a custom app from docker hub, overview of basic Dockerfile directives
- Set up a docker hub account, add & modify images, modify websites
- Using a simple website or JavaScript app, create your own container there are 3 parts, you can do as little or as much as you wish
- Build the container for / with your own app, and run it
- Make it the image available on docker hub
- Run the container, from docker hub image
- This is a little more advanced but it jumps you to using persistent storage for a database container. Containers are stateless by design. In using this lab exercise you make sure the data persists on the host running the container. Note that this type of database container is normally used for testing, not in production. See Instructions MySQL container with persistent storage

- using Travis CI to deploy to github pages

- todo setup/use something like docker beginner labs https://github.com/docker/labs/tree/master/beginner/ from https://github.com/docker/labs
- todo checkout docker play for teaching https://labs.play-with-docker.com/ signin with docker id/pwd
- Individual todos in the repo generated through findtodo.sh

- Amongst others, see docker command reference for some notes on using docker commands
- See docker-compose command reference for some notes on using docker-compose commands

- simple poc
- I added some commands (figlet), runs to stdout
- tested on / runs on
- ubuntu 18.04 (created & run)

working, not in docker hub
- uses alpine latest
- install xeyes
- X11 -> can be done but containers are not meant to do this, really... see the Makefile
- tested on / runs on
- ubuntu 18.04 (created & run)
Note: Uses X11 so when running the image config needs the following, if you omit you will get Error: Can't open display:
--net=host
-e DISPLAY=${DISPLAY} # environment
-v ${XAUTH}:/root/.Xauthority # volumeconsole app requires X11 forwarding if run remotely
working, not in docker hub
- poc X11 app see also xeyes
- todo add README.md for firefox
- isolate firefox in a container so that things like facebook can't get as much info ??
