Hi
I am getting the following NullPointerException when Keycloak is getting
launched.
A few points about the setup. I have installed keycloak, say k1, in one
machine with postgres, say pg1 as the config store. Then I created a custom
realm, some users, client scope in that setup. Then I took a dump of the
postgres setup via:
```
kubectl exec nordic-mole-postgresql-0 -- bash -c "PGPASSWORD=pguser pg_dump
-U pguser -d pgdb " > db.sql
```
Now I used the postgres dump thus obtained to build another postgres docker
image, say `pg2`
```
FROM library/postgres:11.3
ENV POSTGRES_USER pguser
ENV POSTGRES_PASSWORD pguser
ENV POSTGRES_DB pgdb
COPY db.sql /docker-entrypoint-initdb.d/
```
Now I brought up a fresh version of keycloak, say k2, which talks to this
new pg2 postgres instance via the following command.
```
helm install codecentric/keycloak -f values.yaml
```
The values.yaml contains connection details for the 2nd database:
```
keycloak:
persistence:
deployPostgres: false
dbVendor: postgres
dbName: pgdb
dbHost: postgres # Resolved through k8s service
dbPort: 5432
dbUser: pguser
dbPassword: "pguser"
```
Now I have two questions:
1) Should I report the following crash in a bug system of some kind ?
2) Is there a simpler, cleaner way of creating a new realm, new user via
the `values.yaml` instead of taking dump of postgres ? Are there any good
tutorials, github projects etc. that explain this ?
Thanks.
The Stacktrace of the actual crash below:
13:34:03,343 ERROR [org.jboss.as.controller.management-operation]

It usually happens that before metrics failure, there's a database
connection failure. Please check your logs a bit earlier than the
stacktrace you posted.
Also, there's a Docker Compose example with Postgresql:

ah yes, I found the cause:
3:31:23,238 ERROR

So it seems, the pg_dump that I took and did a pg_restore here did not
help. The keycloak pod while coming up, is trying to create a table
while it is already there. I am not sure if this is a bug on keycloak
side or if I am misunderstanding something. The pods are ephemeral and
they could get deleted and come anytime, no ? Should this be a "CREATE
OR REPLACE TABLE admin_event_entity" or a "CREATE TABLE IF NOT EXISTS
admin_event_entity" ?
Also, there's a Docker Compose example with Postgresql:
