- For non-rhel8, guacnet_cidr and the associated guacnet_<ip> variables must not be in use, they're for docker services.
- For rhel8, guacnet_<ip> variables must be within 10.88.0.0/16, the default podman network. This is a podman limitation.
- if needed, database credentials are available in /opt/guacamole on the docker host.
- guacadmin:guacadmin are the default web admin credentials.
- http://localhost:8080/guacamole is the default web endpoint.
- tested with CentOS 7, Ubuntu 18.04, and RHEL 8
