Something is weird in my local environment. When I run docker compose build keycloak the container is builded. After docker compose up -d I run into the common keycloak screen, shown below. When I run docker compose build though, I receive the follwing error failed to solve: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount2400951532/Dockerfile: no such file or directory

I don't know if the build error is related to keycloak but to the missing submodule checkout? I have activated the theme only for the augustin realm and not for the master. Try something like the following url: http://keycloak:8080/realms/augustin/protocol/openid-connect/auth?response_type=code&scope=email%20profile%20openid%20offline_access%20roles&client_id=wordpress&state=1220ed43e816f41ef2519f8bd7d7c18d&redirect_uri=http%3A%2F%2Flocalhost%3A8090%2Fwp-admin%2Fadmin-ajax.php%3Faction%3Dopenid-connect-authorize
