2 Public cloud images

  

SUSE offers a variety of different product images for different use cases in partner cloud provider frameworks. Learn how to find the image that meets your use case.

2.1 Image lifecycle

  

All SUSE public cloud images follow a refresh cycle up to the point of deletion. The refresh cycle follows a 'rolling' three month time frame. What this means:

  • Images in an active state are refreshed every three months. Replaced images are moved to the deprecated state.

  • If a critical security vulnerability occurs, images in active and inactive states are updated as soon as possible once the fix for the affected code is available. For images in active state the three month timer restarts with this forced replacement.

    SUSE is committed to address all security vulnerabilities disclosed through the Common Vulnerabilities and Exposures process (CVE) and a score of 9.0 or greater in the Common Vulnerability Scoring System (CVSS). For more information about the effects and rating of CVEs, refer to the SUSE CVE database.

The life cycle of an image consists of four different states:

SUSE public cloud image states
  
Active

Active images are fully supported and refreshed at least every three months. The duration lasts until the image is replaced by a newer image version.

Inactive

Inactive images are supported following the rules of LTSS or ESPOS and will only get refreshed for critical security updates. The duration term is defined by the product. For more information, refer to https://www.suse.com/de-de/support/policy-products/#cloud

Deprecated

Deprecated images may no longer be supported. The status of support depends on the support status of the product in the image. Deprecated images do not get refreshed and are not made available in regions added after an image has been set to deprecated. At the end of the six month deprecation period, images are subject to deletion. It is strongly discouraged to use deprecated images to create new instances.

Deleted

Deleted images are no longer supported or available for instance creation.

Important
Important: Only use active images for new instances

It is strongly recommended to only use active images to launch instances for new deployments.

2.2 Naming scheme

  

Names for SUSE's public cloud images consist of multiple parts that contain information about the product, its version, a time stamp indicating the release date of the image, and more. The general naming scheme for SUSE's public cloud images is as follows:

PRODUCT-FLAVOR-vVERSION-VIRTUALIZATION-STORAGE-ARCHITECTURE-TAXID-GEN

Not all components of this naming scheme are used in all frameworks.

SUSE public cloud image naming scheme
  
PRODUCT

Abbreviated name of the product in lower case letters, e.g. suse-sles-15-sp3 or suse-manager-4-1-proxy. This part may also be “search-optimized” per cloud framework. For example the prefix suse- helps when searching for SUSE in the general catalog in Amazon Web Services.

FLAVOR

Images can have different flavors such as chost or byos. If it is the default image of a product, this part will be omitted. Multiple FLAVOR attributes may be combined in an image name. For example sles-15-sp3-chost-byos is an image build based on SUSE Linux Enterprise Server 15 SP3 build as a container host using a BYOS (Bring Your Own Subscription) billing model. Images without byos in the name are set up the image is set up for PAYG (Pay As You Go) billing. For more information about the different billing models, refer to Section 1.3, “Plans”.

SUSE Linux Enterprise flavors
  

  • byos: Bring your own subscription (BYOS) image

  • chost: Minimal container host image

  • hardened: Pre-hardened images, see Section 2.5, “Hardened Images”

  • hpc: SUSE Linux Enterprise High Performance Computing image

  • sap: SUSE Linux Enterprise Server for SAP Applications image

  • sapcal: SAP Cloud Application Library image

Not all flavors are available for all cloud frameworks; some are provider-specific.

Amazon Web Services flavors
  

  • ecs: Amazon Elastic Container Service image

Microsoft Azure flavors
  

  • basic: PAYG image that only includes updates but no support

  • standard: Fully supported PAYG image

VERSION

Upload date of the image in the format vYYYYMMDD (ISO 8601).

VIRTUALIZATION (AWS-only)

SUSE no longer supports or publishes para-virtualized images. The virtualization type was encoded as pv (para-virtualized) or hvm (hardware-assisted virtual machine). The hvm part of the image name has been retained in an effort to not break backward compatibility.

STORAGE (AWS-only)

SUSE no longer publishes images that are based on hard disk (magnetic) backed storage. This used to be encoded as mag. All published images are backed by SSD. The ssd part of the image name has been retained in an effort to not break backward compatibility.

ARCHITECTURE

Either x86_64 or arm64. SUSE no longer supports or publishes 32 bit x86 images. Images with the i386 identifier are visible in Public Cloud Information Tracker data.

TAXID

Either llc or ltd. Only for images with SUSE priority support. For more information, refer to Section 1.4, “Support”

GENERATION (Microsoft Azure-only)

appended as gen2 for 2nd Generation VMs.

2.3 Public Cloud Information Tracker

  

The Public Cloud Information Tracker (PINT) provides information about the images SUSE publishes and servers that are part of the SUSE operated update infrastructure. PINT is available at https://pint.suse.com/ and provided as an API and command-line tool with the python3-susepubliccloudinfo package from the Public Cloud Module repository.

Use the drop-down lists to view images, servers, or both, and filter by cloud framework, region, or image state. You can also search for strings and adjust the columns and the number of results per page.

2.3.1 Images view

  

The following columns are shown in the Images view. Some columns depend on the the cloud frameworks.

Columns in the Images view
  
Name

Name of the image. For more information about the image naming scheme, refer to Section 2.2, “Naming scheme”.

State

State of the image. Can be one of All states, active, inactive, deprecated, or deleted. Note that All States excludes images in the deleted state. Deleted images may be viewed by explicitly selecting deleted as the image state. For more information information about image stated, refer to Section 2.1, “Image lifecycle”.

Replacement

Name of the image that replaces another.
