Deployment is supported on Ubuntu 16.04 and 18.04. Support for Ubuntu 20.04 is in preparation.
The manager node must be at least an Ubuntu 18.04 as of the 2020.2 release. Managers with Ubuntu 16.04 are no longer supported.
The use of Ubuntu 16.04 is no longer recommended and will not be supported in the future
Other distributions are currently not supported.
If the deployment is carried out or supervised by us, direct SSH access to the system acting as manager is required.
Optimally, a VPN is provided via which all relevant nodes including the remote consoles can be accessed.
Services & Access¶
The nodes need access to some external services.
DNS and NTP servers
Docker Hub / Quay.io
Official Ubuntu mirrors
Mirrors for Docker and Ubuntu can be provided within the environment. Then access to Docker Hub / Quay.io and Ubuntu mirrors is only required from the manager.
If no direct access to external services is possible, the use of an HTTP proxy is possible.
GitHub or an internal Git repository server (e.g. Gitlab)
