According to https://groups.google.com/forum/#!topic/repo-discuss/9PTfVG8vdAU

the known_hosts file encoding is the issue - needs to be ssh-rsa not ecdsa-sha2-nistp256 which jgit is unhappy with.

PostgreSQL can be accessed via port 5432 on the following DNS name from within your cluster:
    pgstg-postgresql.default.svc.cluster.local - Read/Write connection
To get the password for "postgres" run:
    export POSTGRES_PASSWORD=$(kubectl get secret --namespace default pgstg-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
To connect to your database run the following command:
    kubectl run pgstg-postgresql-client --rm --tty -i --restart='Never' --namespace default --image docker.io/bitnami/postgresql:10.7.0 --env="PGPASSWORD=$POSTGRES_PASSWORD" --command -- psql --host pgstg-postgresql -U postgres


To connect to your database from outside the cluster execute the following commands:
    kubectl port-forward --namespace default svc/pgstg-postgresql 5432:5432 &
    PGPASSWORD="$POSTGRES_PASSWORD" psql --host 127.0.0.1 -U postgres

describe pod shows
  Warning  FailedScheduling  21s (x6 over 3m42s)  default-scheduler  pod has unbound immediate PersistentVolumeClaims
Workaround:
