Passing variables for use in config.yml?

[notflip]

What's the best way to create a general script, based on the example from this repo, which allows us to pass variables to the config.yaml file inside /data/borgmatic.d/config.yaml?

Thanks!

How are the variables intended to be used in borgmatic's configuration file and where you do you want them to come from? You can pass in environment variables when you run the container (e.g. with --env) and then access them in configuration.

Thanks @witten I want to pass, for example the URL of my healthchecks ping, so if I undestand correctly I can add it to my .env file
PING_URL=https://healthchecks.whatever

and then use

healthchecks:
  ping_url: ${PING_URL}

Yeah that sounds right, assuming your .env file is used to create your containers (via docker run or Docker Compose).
