PuppetDB requires a separate read-only database user for its read pool.
Without it, it refuses to use the write user for read queries and all
/pdb/query/v4 calls fail with a 500.
- Add puppetdb_read role via CNPG managed.roles with password sourced
from a new postgres-read-credentials Vault secret
- Grant CONNECT, USAGE, SELECT and default privileges to puppetdb_read
via postInitApplicationSQL (must also be run manually on existing cluster)
- Add puppet-postgres-pooler-ro Pooler (type: ro) routing to replicas
- Add puppetdb-read-database-conf ConfigMap with read-database.conf
mounted into /etc/puppetlabs/puppetdb/conf.d/ in the PuppetDB deployment
- Wire OPENVOXDB_READ_POSTGRES_* env vars from the new secret

working towards a larger, redundant, autoscaling and simple puppet
implementation in kubernetes. this was originally based on the openvox
helm chart with several improvements (not all in this pr)
- use of cnpg instead of single bitnamilegacy postgres container
- use for g10k instead of r10k
- run one instance of g10k per namespace, instead of per-pod
- store only keep one copy of the environments/branches (instead of per-pod)
- change g10k to native cronjob instead of hacky implementation
- use vault secrets
part one adds:
- cnpg puppetdb pgsql cluster
- cnpg puppetdb pgpooler
- persistent volume claims for puppet, puppetdb, the code repository, etc
