Hello all,

Actually we have keycloak 16.1.1 and we want migrate to 19.0.2.

To do that i can migrate directly to 19.0.2 or i need migrate to 17,18 and 19 ?

Best regards

Hi David,

I migrated from 16 to 19 without any issues (using the official
containers). Of course, you need to backup your DB just in case. I
also migrated to the quarkus distribution, so I had the redo the
complete build and deployment flow.

Regards,

C.

Hi,

Thanks for your feedback it's good news for us.

I have try to deploy on K8S context (without operator) we have legacy yaml files to declare deploy, ingress ...

I build image with documentation : https://www.keycloak.org/server/containers like you i thing.

I have an issue when container running on K8S:

ERROR: Build failure: Build failed due to errors

...

I don't understand why keycloak want to 'Build' and why it failed.

I try to launch locally docker image on my laptop and i don't have this behavious.

Thank's for your help.

David.

I use Nomad instead of Kubernetes, so I don't inmediately see where is
goes wrong.
Did you use a multi-stage build like the documentation example and did
you copy the build result to the next stage? Is Kubernetes trying to
build it again?

Yes, i use multi-stage build like documentation.

In my yaml file (deployment) i have added args 'start' to start keycloak on production mode and in this case k8s try to build again (and failed).

I testing new option to launch with args : 'start --optimized' and now i have an issue because hostname isn't define, i thing that it's better i continue to search.
