Repository Details

Preflight Checks and Support Bundles Framework for Kubernetes Applications

Replicated Troubleshoot

Replicated Troubleshoot is a framework for collecting, redacting, and analyzing highly customizable diagnostic information about a Kubernetes cluster. Troubleshoot specs are created by 3rd-party application developers/maintainers and run by cluster operators in the initial and ongoing operation of those applications.

Troubleshoot provides two CLI tools as kubectl plugins (using Krew): kubectl preflight and kubectl support-bundle. Preflight provides pre-installation cluster conformance testing and validation (preflight checks) and support-bundle provides post-installation troubleshooting and diagnostics (support bundles).

To know more about troubleshoot, please visit: https://troubleshoot.sh/

Preflight Checks

Preflight checks are an easy-to-run set of conformance tests that can be written to verify that specific requirements in a cluster are met.

To run a sample preflight check from a sample application, install the preflight kubectl plugin:

curl https://krew.sh/preflight | bash

and run, where https://preflight.replicated.com provides an example preflight spec:

kubectl preflight https://preflight.replicated.com

NOTE this is an example. Do not use to validate real scenarios.

For more details on creating the custom resource files that drive preflight checks, visit creating preflight checks.

Support Bundle

A support bundle is an archive that's created in-cluster, by collecting logs and cluster information, and executing specified commands (including redaction of sensitive information). After creating a support bundle, the cluster operator will normally deliver it to the 3rd-party application vendor for analysis and disconnected debugging. Another Replicated project, KOTS, provides k8s apps an in-cluster UI for processing support bundles and viewing analyzers (as well as support bundle collection).

To collect a sample support bundle, install the troubleshoot kubectl plugin:

curl https://krew.sh/support-bundle | bash

and run, where https://support-bundle.replicated.com provides an example support bundle spec:

kubectl support-bundle https://support-bundle.replicated.com

NOTE this is an example. Do not use to validate real scenarios.

For more details on creating the custom resource files that drive support-bundle collection, visit creating collectors and creating analyzers.

And see our other tool sbctl that makes it easier to interact with support bundles using kubectl commands you already know

Community

For questions about using Troubleshoot, how to contribute and engaging with the project in any other way, please refer to the following resources and channels.

Software Bill of Materials

A signed SBOM that includes Troubleshoot dependencies is included in each release.

  • troubleshoot-sbom.tgz contains a software bill of materials for Troubleshoot.
  • troubleshoot-sbom.tgz.sig is the digital signature for troubleshoot-sbom.tgz
  • key.pub is the public key from the key pair used to sign troubleshoot-sbom.tgz

The following example illustrates using cosign to verify that troubleshoot-sbom.tgz has not been tampered with.

$ cosign verify-blob --key key.pub --signature troubleshoot-sbom.tgz.sig troubleshoot-sbom.tgz
Verified OK

If you were to get an error similar to the one below, it means you are verifying an SBOM signed using cosign v1 using a newer v2 of the binary. This version introduced breaking changes which require an additional flag --insecure-ignore-tlog=true to successfully verify SBOMs like so.

$ cosign verify-blob --key key.pub --signature troubleshoot-sbom.tgz.sig troubleshoot-sbom.tgz --insecure-ignore-tlog=true
WARNING: Skipping tlog verification is an insecure practice that lacks of transparency and auditability verification for the blob.
Verified OK
