Also adds the ability to overwrite the image in docker-compose.yml,
which allows the CI build to use the same image for all docker tests.
The default is still 'benbusby/whoogle-search' though.
Initializing the DDG bangs when running whoogle for the first time
creates an indeterminate amount of delay before the app becomes usable,
which makes usability tests (particularly w/ Docker) unreliable. This
moves the bang json init to a background thread and writes a temporary
empty dict to the bangs json file until the full bangs json can be used.
Split previous docker test CI into one for PRs and one for triggering
the main buildx workflow that deploys new images to Docker Hub.
Note that this needs to be further refactored soon to use reusable
workflows. The main portion of docker/docker-compose tests is duplicated
between the new main + test workflows.
It makes more sense to structure the order of tests to go from api and
unit testing -> validate docker image works as expected -> build and
deploy docker image.
This expands on the current testing suite a bit by introducing a new
workflow for testing functionality within the docker container. It runs
the same test suite as the regular "test" workflow, but also performs a
health check after running the app for 10 seconds to ensure
functionality.
The buildx workflow now waits for the docker test script to finish
successfully, rather than the regular test workflow. This will hopefully
avoid situations where new images are pushed with issues that aren't
detected in regular testing of the app.
