Supported Environments

The following environments have been tested and are the main environments the project works with. Other Kubernetes based environments might work as well. Please provide feedback if you are running in other environments. But be aware that we cannot look into all distributions and run-time environments.

Supported run-time environments

Docker CE 20.10+ on Linux/Docker Desktop on Mac, Docker Desktop on Windows (Optional with Docker Compose V1.26+)
Podman 3.3.0+ *)
Kubernetes (K8s) v1.20+
RedHat OpenShift 4.x+

*) Note: If Podman and Docker are installed on the same machine, Podman is used by default. You can switch manually from Podman to Docker for the build and run-time environment using CONTAINER_CMD=docker either in the configuration or exporting an environment variable in your shell.

Supported build environments

Docker CE 20.10 and higher on Linux
Docker Desktop on Mac
Docker Desktop on Windows building with a WSL2 sub-system
Podman 3.3.0+ on Linux *)
Rancher Desktop 1.5+ with Docker back-end

*) Same Podman / Docker note applies

Supported base images

RedHat Universal Base Image (UBI) 8.6 + 9.x
CentOS Stream 8.x + 9.x
RockyLinux 8.x + 9.x
AlmaLinux 8.x
VMware PhotonOS 4
SUSE Leap 15.3+
SUSE Enterprise 15.3+
Oracle Linux 8
Amazon Linux

Experimental base images

Ubuntu 22.x
Debian 11.x

Recommended Linux Versions and Tips

Docker CE and Podman are available in most distributions. Some distributions come with Docker CE or Podman included. Before you install Docker CE or Podman, please check if your platform provides the required version.

RHEL 8 / CentOS Stream 8+ ship with a current version of Podman
SUSE SLES / Leap 15.3+ a shipps with a current Docker version
If your platform does not come with a current Docker version there is an official Docker Linux setup documentation

Recommended combinations (9/2022)

Build and run-time environments

RHEL/CentOS Stream 8/9 with Docker 20.x or Podman 3.3.0+
SUSE SLES / Leap 15.3+ with Docker 20.x or Podman 3.3.0+
Current Rancher Desktop (Docker environment)
Current version of Docker Desktop with WSL2 sub-system to build the image
Current version of Docker Desktop on Mac

Run-time environments

Current version of Docker Desktop on Windows
k3s Rancher
Current Rancher Desktop
Current version of Kubernetes
Current versions of OpenShift

Tested base images

The following Linux base images have been tested.
Current default base image is CentOS Stream 8.
Resulting image size differs by base image.
The smalles base images are based on PhotonOS

Note:
Many base images use a kernel 5.x already.
The 5.x kernel is officially supported starting with Domino 12.0.2. Ensure the base operating systems is also running a comparable 5.x kernel.

Short names below can be used with the build.sh -from=image option.
For example build based on Redhat UBI : ./build.sh domino -from=ubi

Note: When not specifying a major version, the major version default could change and result in a newer major kernel version!
