mirror for provider plugins does not work for staging about terraform-tuesdays HOT 1 CLOSED

You are correct, if you were maintaining this on a networking mirror, you would probably need to do the following:

1. Update the version used in code
2. Run the terraform providers mirror command again with the same output directory
3. Upload the resulting files (index.json will automatically be updated

I'm sure this solution could be scripted out and run as the version you use for providers is updated. You could also keep a set of terraform configs that only define the providers you use in your environment and run terraform providers mirror against each config with the same target output directory as mention in the official docs:

If you wish to create a mirror with providers for a number of different Terraform configurations, run terraform providers mirror in each configuration in turn while providing the same output directory each time. Terraform will then merge together all of the requirements into a single set of JSON indices.
