Keycloak 无法连接到 Postgres：“需要 SSL 连接”

Question

I'm setting up KeyCloak on my Azure-Kube.netes-Cluster. KeyCloak is supposed to connect to my Azure-Postgres Database. It Fails with: "FATAL: SSL connection is required. Please specify SSL options and retry."

Without Postgres (deleting all DB-Attributes) Keycloak works fine (using default h2), including the ingress. Couldn't find any other information on how to configure it correct.

Answer 3

I stumbled upon this question when I had the exact same problem. I'm using keycloak but connection to a Digital Ocean postgres database over ssl.

You can specify the environment variables to be used by JDBC. I had to requre ssl and specify my certificate. This was done with the following environment variable:

JDBC_PARAMS=sslmode=require&sslcert=ca-certificate.crt

I mounted the ca-certificate.crt file in (default folder)

/root/.postgresql/ca-certificate.crt

Read more about other possible configuration here:https://jdbc.postgresql.org/documentation/head/connect.html#ssl

Answer 4

Adding to @DNRN's answer, you need to allow keycloak access to the postgres cert(s). A volume mount on the docker container will be owned by root, so you need to change the ownership to jboss.root for whichever folder you mount if you use the jboss/keycloak image. For example:

chown -R jboss.root /root/.pg_certs/

Note: You need to run the command above as root .

Answer 5

Try

 name: "JDBC_PARAMS"                
 value: "sslmode=require"
