Hi Everyone,
I'm attempting to create a failover cluster that uses Postgresql and
Keycloak and am having difficulty getting Keycloak running. Keycloak is
using a Postgresql database. In one case I'm using DRBD to replicate the
data and in another case I'm using Postgresql. The failure, in both cases,
is that Keycloak fails to connect to the database. In both cases Pacemaker
is running with the Postgresql resource when I add the Keycloak resource.
If I "docker run" Keyclock, not adding it as a Pacemaker resource, Keycloak
starts and connects to the database.
Below adds Keycloak as a Pacemaker resource:
pcs cluster cib cluster1.xml
pcs -f cluster1.xml resource create p_keycloak
ocf:heartbeat:docker image=jboss/keycloak name=keycloak run_opts="-d
-e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin -e DB_ADDR=postgres
-e DB_VENDOR=postgres -e DB_USER=postgres -e DB_PASSWORD=postgres -e
DB_DATABASE=keycloak_db -e JDBC_PARAMS=useSSL=false -p 8080:8080 -e
DB_ADDR=postgres -e DB_PORT='5432' –network=cluster1dkrnet" op monitor
interval=60s
pcs -f cluster1.xml resource group add g_receiver p_keycloak
pcs cluster cib-push cluster1.xml --config
Below creates a Keycloak container that is not managed by Pacemaker:
docker run --name keycloak -e KEYCLOAK_USER=admin -e
KEYCLOAK_PASSWORD=admin -e DB_ADDR=postgres -e DB_VENDOR=postgres -e
DB_USER=postgres -e DB_PASSWORD=postgres -e DB_DATABASE=keycloak_db -e
JDBC_PARAMS=useSSL=false -p 8080:8080 -e DB_ADDR=postgres
-e DB_PORT='5432' --network=cluster1dkrnet jboss/keycloak
Does anyone have experience with Pacemaker with Keyclock and/or if there
are any thoughts about why Keycloak is not connecting to the Postgresql
database?
Thanks in advance.
