Provisioning TLS certificates

Provisioning TLS certificates

This page is primarily for the team. It's public so that you can learn from it. For help using, see the user docs.

We use one wildcard TLS certificate for each environment, plus an additional certificate for customer applications in production:

  • Development: *
  • Staging: *
  • Production system: *
  • Production customer: *

We provision certificates using Let’s Encrypt. Our terraform pipeline checks certificate expiration dates daily and renews certificates that are about to expire. Our load balancers are configured to use the latest certificate; updating load balancers requires re-applying terraform stacks.
