I am working on a Keycloak POC and I have successfully created an image and deployed it to an Azure Kubernetes Service cluster.
When I access the app I am prompted to create the admin user (as expected).
I can access Keycloak using localhost:8443 and create the admin account.
I get a 404 error though on the file step1.html when trying to access the admin console.
This is the path that generates the 404 error: https://localhost:8443/realms/master/protocol/openid-connect/3p-cookies/step1.html?version=56pvt
I had the same issue. I had an old version of keycloak and wanted to update it to 19.x. My setup needs to be deployed under the path /auth. So I used KC_HOSTNAME_PATH=auth.
But apparently that messes up the admin panel. The admin panel doesn’t take this KC_HOSTNAME_PATH into account apparently (my guess). In order to make it work I had to redirect / and /auth to the root of keycloak. See my ingress config:
