I'm following this keycloak documentation on how to get the KC optimised image running on docker:
https://www.keycloak.org/server/containers
I get the following cryptic error when trying to run the "optimized" keycloak docker image:
(base) welcome@Traianos-MacBook-Pro keycloak-docker % docker run --name mykeycloak -p 8443:8443 \
-e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=P@ssw0rd \
quay.io/keycloak/keycloak:latest \
start --optimized
ERROR: Unexpected error when starting the server in (production) mode
ERROR: Failed to start quarkus
ERROR: Strict hostname resolution configured but no hostname setting provided
For more details run the same command passing the '--verbose' option. Also you can use '--help' to see the details about the usage of the particular command.
It's not clear from the documentation how to resolve this error:
ERROR: Strict hostname resolution configured but no hostname setting provided
Any idea how to resolve this?
The resolution was to update the docs to include the relevant hostname option.
