* Fix unchecked type assertion panic in ChangeImageNameAction
replaceImageName reads a restored container's image field out of the
unstructured object and asserts it to string without checking ok. The
comma-ok map lookup on the line above only confirms the "image" key is
present -- it says nothing about the value's type. A restored resource
whose image field is present but not a JSON string (e.g. a number,
bool, null, array, or object) causes an unrecovered
"interface conversion: interface {} is not string" panic in this
RestoreItemAction plugin whenever the optional image-remapping
ConfigMap feature is configured.
Switch to the comma-ok form of the assertion and skip (with a log
message) any container whose image field isn't a string, instead of
panicking.

* Add regression test for non-string image field panic
Covers the comma-ok assertion fix: replaceImageName operates on
generic unstructured content decoded from a backup tarball, which
isn't validated against the Pod schema before this code runs, so
"image" isn't guaranteed to be a string.

* Guard container-entry type assertion, use unstructured.NestedString
Addresses reviewer feedback: container.(map[string]any) was also an
unchecked assertion, and unstructured.NestedString gives safer,
more idiomatic type-checking than a manual comma-ok assertion. Also
switches the skip-path logging from Info to Warn per review.

Overview
Velero (formerly Heptio Ark) gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. You can run Velero with a public cloud platform or on-premises.
Velero lets you:
- Take backups of your cluster and restore in case of loss.
- Migrate cluster resources to other clusters.
- Replicate your production cluster to development and testing clusters.
Velero consists of:
- A server that runs on your cluster
- A command-line client that runs locally
Documentation
The documentation provides a getting started guide and information about building from source, architecture, extending Velero and more.
Please use the version selector at the top of the site to ensure you are using the appropriate documentation for your version of Velero.
Troubleshooting
If you encounter issues, review the troubleshooting docs, file an issue, or talk to us on the #velero-users and #velero-dev channel on the Kubernetes Slack server.
Community
Velero is an open community and we welcome your participation. The best way to get involved is to join our bi-weekly community meetings:
- Join the Velero community meetings, held bi-weekly, alternating between Beijing-friendly and US/Europe-friendly time zones.
- Subscribe to the project meeting calendar.
- Chat with us on the Kubernetes Slack
#velero-userschannel and join the mailing list.
See the community page for the full schedule and details.
Contributing
If you are ready to jump in and test, add code, or help with documentation, follow the instructions on our Start contributing documentation for guidance on how to setup Velero for development.
Governance
Velero's governance describes how the project is run, including the decision-making process, the roles and responsibilities of maintainers, and how to become a maintainer. Governance applies across the Velero org and is maintained at velero-io/.github.
Changelog

Velero compatibility matrix
The following is a list of the supported Kubernetes versions for each Velero version.
| Velero version | Expected Kubernetes version compatibility | Tested on Kubernetes version |
|---|---|---|
| 1.18 | 1.18-latest | 1.33.7, 1.34.1, and 1.35.0 |
| 1.17 | 1.18-latest | 1.31.7, 1.32.3, 1.33.1, and 1.34.0 |
| 1.16 | 1.18-latest | 1.31.4, 1.32.3, and 1.33.0 |
| 1.15 | 1.18-latest | 1.28.8, 1.29.8, 1.30.4 and 1.31.1 |
| 1.14 | 1.18-latest | 1.27.9, 1.28.9, and 1.29.4 |
Velero supports IPv4, IPv6, and dual stack environments. Support for this was tested against Velero v1.8.
The Velero maintainers are continuously working to expand testing coverage, but are not able to test every combination of Velero and supported Kubernetes versions for each Velero release. The table above is meant to track the current testing coverage and the expected supported Kubernetes versions for each Velero version.
If you are interested in using a different version of Kubernetes with a given Velero version, we'd recommend that you perform testing before installing or upgrading your environment. For full information around capabilities within a release, also see the Velero release notes or Kubernetes release notes. See the Velero support page for information about supported versions of Velero.
For each release, Velero maintainers run the test to ensure the upgrade path from n-2 minor release. For example, before the release of v1.10.x, the test will verify that the backup created by v1.9.x and v1.8.x can be restored using the build to be tagged as v1.10.x.
