Vale Action is slow because it builds Docker image every run

The problem

The Vale Action is slow, because it builds a Docker container every run.

Example

Here's my Github Action run (54 seconds in total):

• 42 seconds is spent on building the Docker image
• only 5 seconds is spent on downloading packages and running Vale

This is annoying when you update your pull requests often.

Ideas

Speed up Vale Action by:

• Use an existing Docker image (for example through this suggestion)
• Cache the built Docker container yourself using a cache step (not sure how)

Any other ideas?

Yes, this is not good. I'm planning on moving away from ReviewDog entirely, but I haven't had time to work on this.

Should be fixed now.
