Gloo Network for Cilium versions

Supported versions link

Solo supports n-3 versions of Gloo Network for Cilium. Within each Gloo Network version, different open source project versions are supported, including n-4 version support for Solo distributions of Cilium.

The following versions of Gloo Network are supported with the compatible Solo versions of Cilium. Later versions of the open source project that are released after Gloo Network might also work, but are not tested as part of the Gloo Network release.

Solo distributions of Cilium link

The Solo distribution of Cilium is a hardened Cilium enterprise image, which maintains support for security patches to address Common Vulnerabilities and Exposures (CVEs) and other security fixes.

Keep in mind that Gloo Network offers security patching support only with Solo distributions of Cilium versions, not community Cilium versions. Solo distributions of Cilium versions support the same patch versions as community Cilium. You can review community Cilium patch versions in the Cilium release documentation. To get the backported Cilium support, you must run the latest Gloo Network patch version.

To download the Solo distribution of a Cilium image, you must be a registered user and be able to log in to the Solo Support Center. Open the Cilium images built by Solo.io support article. When prompted, log in to the Support Center with your Solo account credentials.

Release lifecycle link

Solo supports n-3 for Gloo Network and n-4 for Solo distributions of Cilium.

Typically, Gloo Network releases a new minor version, n, each quarter. When the new minor version is released, the previous n-4 for Gloo Network or n-5 for Solo distributions of Cilium become unsupported. Make sure that you run a supported version for production environments, and keep that version upgraded to the latest patch version so that you have the latest security fixes. For more information, see the upgrade guide.

Gloo feature maturity link

Solo periodically provides new features in minor releases of Gloo versions. To receive feedback and improve functionality for real use cases, these features are often released according to a feature maturity model. As the features are improved and stabilized, they are gradually moved through the stages of alpha, beta, and general availability (GA) support. Review the following table for the comparison points between each stage of feature maturity. To see the maturity of a feature, check the feature’s documentation.

Download a specific image link

You can download a particular image for Gloo Network, such as for the following use cases.

• To download and transfer these images if your environment does not have public network access or cannot pull public images, for an air-gapped installation.
• To use a custom build that aligns with compliance standards such as Federal Information Processing Standards (FIPS).

1. Get the version tag that you want to use.

2. To download the package for all Gloo components that you deploy in your management and workload clusters, append the <version_tag> to the following URL.

     https://storage.googleapis.com/gloo-platform/helm-charts/gloo-platform-<version_tag>.tgz
     

3. Optional: For FIPS-compliant images, open the values.yaml file in the downloaded package, search for the image section, and append -fips to the tag, such as in the following example.

     ...
   glooMgmtServer:
     image:
       pullPolicy: IfNotPresent
       registry: gcr.io/gloo-mesh
       repository: gloo-mesh-mgmt-server
       tag: 2.5.6-fips
     

4. Optional: If you need to pull the images locally, such as for an air-gapped installation, you can use the information you retrieved from the images section in the values.yaml file to pull the image. For example, you might use the following docker pull command for a FIPS image. Repeat this step for each image that you want to build locally and push to a private repository.

     docker pull gcr.io/gloo-mesh/gloo-mesh-mgmt-server:2.5.6-fips
     

5. Use these packages when you install Gloo Network.
