Terraform for Keycloak

This contains the Terraform configuration for deploying TVL's Keycloak instance (which lives at auth.tvl.fyi).

Secrets are needed for applying this. The encrypted file //ops/secrets/tf-keycloak.age contains export calls which should be sourced, for example via direnv, by users with the appropriate credentials.

An example direnv configuration used by tazjin is this:

# //ops/secrets/.envrc
source_up
eval $(age --decrypt -i ~/.ssh/id_ed25519 $(git rev-parse --show-toplevel)/ops/secrets/tf-keycloak.age)
