Docker Hub Images

Hi zorchenhimer,
Could you set up automated Docker builds and images to be pushed to Docker Hub?
I don't really know docker all that well, but this is something that I would like to setup. Learning docker is on my todo list.
I would suggest using GitHub Actions, as, well, you are already using GitHub. You would have to create a DockerHub Account and then push the images to there. I don't have much experience with GitHub Actions, but I played around a bit and something like this should suffice to push out an latest image:
name: Docker Image CI
on:
# Triggers the workflow on push or pull request events but only for the master branch
push:
branches: [ master ]
# Allows you to run this workflow manually from the Actions tab
workflow_dispatch:
jobs:
build:
runs-on: ubuntu-latest
steps:
# Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
- uses: actions/checkout@v2
- name: Push to Docker Hub
uses: docker/build-push-action@v1
with:
username: ${{ secrets.DOCKERHUB_USERNAME }}
password: ${{ secrets.DOCKERHUB_PASSWORD }}
repository: my-docker-hub-namespace/my-docker-hub-repository
tags: latest
Just create a personal access token on Docker Hub and then save your username and the token as a secrets in this Git Repository (under Settings -> Secrets).
Then match the repository name in the 2nd last line of above to the one you have on Docker Hub.
This would currently push on every change on master. I think from reading here https://github.com/features/actions that with a free plan you have about 2000 free minutes per month, if that doesn't suffice I would suggest removing the automated build on push to master and just start it manually whenever you think it's worth it.
Docker Hub can also build the image without the need for GitHub Actions. Example from one of my repos:
