DEVELOPER INSTRUCTIONS:

1. Download and extract the DoD CAs to this directory
   https://repo1.dso.mil/platform-one/big-bang/apps/developer-tools/gitlab/-/tree/main/chart/bigbang/DoD_CA_certs
2. Then insure that there is a secret created for each sub-directory of certs. The CA certs are broken into separate secrets to avoid he potential of passing the k8s 1 Mb size limit.
   https://repo1.dso.mil/platform-one/big-bang/apps/developer-tools/gitlab/-/blob/main/chart/templates/bigbang/secrets/DoD_CA_certs.yaml
3. Then sync the secret names in the Gitlab values file .Values.certificates.customCAs
   There might be some miss-formatted/invalid certs that need to be deleted. They will be revealed by testing a Gitlab deployment with the new CA certs.

Keycloak creates a consolidated dod_cas.pem file but without the email and software certs. This might be of interest for side-study.
