[keycloak-user] Has anyone installed keycloak using snap or juju

I created a new Ubuntu 18.10 Server VM During install It had a step about installing common snaps. Keycloak was one of them. I selected it and I have no idea about how or where it installed keycloak or how to start keycloak. I'm dubious as to it's usefulness as Java did not get installed. Googleing has informed me a bit about snapd (snappy) and juju, but my attempts at using them were futile. Are snap and juju based installation packages still half baked?
