We strongly recommend at least 2 CPUs and 4 GB RAM per worker node in production environment. Any less in development environment is ok but will leave little room for your workloads.
- CentOS 7.4+ (amd64 and arm64)
- Ubuntu 18.04 LTS+ (amd64 and arm64)
- Fedora 31 (amd64)
- Debian 9.1 (amd64)
Other platforms may work well but are not tested in our production environment. Supplements to the list are welcome.
