Applies to SUSE Linux Enterprise Server 15 SP3

14 Compatibility and support plans Edit source

14.1 SUSE Linux Enterprise container support matrix Edit source

Consult the following support and compatibility matrix to make sure that the desired host system and container combination is compatible and supported.

In most scenarios, all SLE containers are expected to be interoperable if the application or its dependencies do not interact directly with kernel version-specific data structures (ioctl, /proc, /sys, routing, iptables, nftables, eBPF, etc.) or modules (KVM, OVS, SystemTap, etc.). Support for ioctl and access to /proc is limited to the most common scenarios needed by unprivileged uses.

14.2 Support plans Edit source

There are three guiding principles of SUSE container support.

  1. The container image lifecycle follows the lifecycle of the related products.

    For example, SLES 15 SP3 container images follow the SLES 15 SP3 lifecycle.

  2. Container release status also matches the status of the related product.

    For example, if SLES 15 SP3 is in Alpha, Beta, RC, or GA stage, the related containers have the same release status.

  3. Containers are built using the packages from the related products.

    For example, SLES 15 SP3 container images are built using the same packages as the main SLES 15 SP3 release.

14.3 Supported containers on SUSE host environments Edit source

The following support options (tiers) apply to SUSE Linux Enterprise Server and SUSE CaaS Platform containers on SUSE host environments.

14.3.1 Tier one Edit source

Containers delivered by SUSE

Containers delivered by SUSE are fully supported. This applies to both the container and host environment as well as all products under support. This includes both general support and Long Term Service Pack Support (LTSS).

14.3.2 Tier two Edit source

Containers delivered by partners with an agreement ensuring a joint engineering collaboration

This tier targets important Independent Software Vendors (ISVs). Partner containers with a joint engineering collaboration agreement are fully supported. This applies to both the container and host environment as well as all products under support (both general, as well as LTSS) covered by the agreement. Products not covered by the agreement fall under Tier Three.

14.3.3 Tier three Edit source

All other third-party containers

The SUSE container host environment is fully supported. However the container vendor is responsible for handling issues related to third-party containers they maintain.

14.4 Supported container host environments Edit source

The support options (tiers) covered below apply to the following container options:

  • SUSE Linux Enterprise base containers

  • Containers delivered by SUSE

  • Third-party container environments derived from the SLE base containers

  • Third-party containers built from SLE packages using KIWI

14.4.1 Tier one Edit source

SUSE products

This tier applies to SUSE Linux Enterprise Server, SUSE CaaS Platform, and SUSE Cloud Application Platform. Both the containers and host environments delivered by SUSE are fully supported as well as all products under support. This includes both general support and LTSS.

14.4.2 Tier two Edit source

Third-party vendors with an agreement ensuring a joint engineering collaboration

Partner containers and host environments with a joint engineering collaboration agreement are fully supported. This applies to both the container and host environment as well as all products under support (both general and LTSS) covered by the agreement.

14.4.3 Tier three Edit source

Selected third-party vendors with no agreement

This tier targets environments delivered by selected third-party vendors. While SUSE-based containers are fully supported, issues in the host environment must be handled by the host environment vendor. SUSE supports components that come from the SUSE base containers. Packages from SUSE repositories are also supported. Additional components and applications in the containers are not covered by SUSE support. A SLE subscription is required for building a derived container.

14.4.4 Tier four Edit source

Any other container host environment

Any container host environment not mentioned in the support tiers above has limited support. Details can be discussed with the SUSE Support Team, who might triage the issue and recommend alternative solutions. In any other case, issues in the host environment must be handled by the host environment vendor.
