Apple MacBook M1 issues
In case you're using a current Apple MacBook with M1 CPU, you might encounter the issue that Keycloak just won't start (local testing purposes). We resolved this issues ourselves by rebuilding the image locally. Doing so might look like the following:
#!/bin/zsh
cd /tmp
git clone git@github.com:keycloak/keycloak-containers.git
cd keycloak-containers/server
git checkout 16.1.0
docker build -t "jboss/keycloak:16.1.0" .
