SSH Access
To access your servers over SSH, in the the Admin Console choose Server Access and follow the guide. Note that 2-factor authentication is set up by default, so you will need a 2FA device with an application installed like Google Authenticator to connect to your servers.
Your servers are running Ubuntu 18.04 Bionic Beaver.
Biome Services
The services required for Hubs Cloud are installed, managed, and supervised with the Biome Supervisor, which is the community distribution of Chef Habitat. To better understand how Biome works, you can read the Chef Habitat Guide.
The biome commandline tool is bio, and services run under the hab user.
Logging
Logging is sent to journald. To tail the log, as root you can use journalctl:
journalctl -f
Managing services
To see the list of running services, as root:
bio sup status
You can start/stop services via bio svc start and bio svc stop. It's advised that you not unload or load services via bio svc load or bio svc unload manually since that will disconnect from the channel, preventing updates, etc.
