Docker hub images are outdated

[ionparticle]

Summary:

Looks like the auto build setup that solved #1245 is no longer working. The images on docker hub haven't been updated for 8 months.

Steps to reproduce:

1. Visit Canvas docker hub and check the image dates.

Expected behavior:

Newer docker images to be available periodically.

Actual behavior:

Stuck on old image.

Additional notes:

Are you abandoning the docker images?

Does anyone have a workaround? Other than just "build it yourself" (which would be fine if there were some docs or tips on how to do it).

[ionparticle]

@LordRatte a regular docker build works, say you want to build the current stable Canvas, make sure you're on the stable branch in the repo and run: docker build -t instructure/canvas-lms:stable .

It took around 8 GB of RAM and an hour to build for me. Not exactly trivial and definitely not something you'd want to debug if anything goes wrong.

If it worked, you'll have the updated image in your docker cache, and it'll use that image instead of pulling the old one on docker hub.

@ionparticle Thank you. That is so helpful. My mistake when doing it manually was probably running it from master.

More recent Dockerfile changes are making it very hard to build the images locally.
Would be great if the stable branch was published to dockerhub again
