generate test image from master

[GeoDerp]

In theory, this additional github action will run every time a commit has been pushed into the master branch.
It will automatically generate a test tagged image, which could be used to test the latest changes on emhass-add-on / docker, prior to pushing a new release.

It also makes it easier for other users to check the changes and add comments before releasing.

And how can we launch this image?
Something like this?

docker run -it -p 5000:5000 --name emhass-test -v ./options.json:/data/options.json emhass/test

With some secrets defined in options.json to access the HA instance

Should be the exact same as the original (pulling from the container registry). however you will be pulling from ghcr.io/davidusb-geek/emhass:test instead of ghcr.io/davidusb-geek/emhass:v0.11.4
you can also select the emhass-test version from emhass-add-on

Example:

# run Docker image, mounting config.json and secrets_emhass.yaml from host
docker run --rm -it --restart always  -p 5000:5000 --name emhass-container -v ./config.json:/share/config.json -v ./secrets_emhass.yaml:/app/secrets_emhass.yaml ghcr.io/davidusb-geek/emhass:test

just hold for two secs before merging however, I think I found a tag bug.

looks good now 👍

p.s. This is what it looks like on emhass-add-on
