The development guide describes how to quickly get set up to build Strimzi from source. Before submitting a patch, make sure you understand how to test your changes by reading the Test guide. The release checklist describes the steps needed for a new version release. The documentation contributor guide describes how to contribute to Strimzi documentation.

Developer Certificate of Origin

The Developer Certificate of Origin (DCO) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project. All commits must be signed off by adding a Signed-off-by line to the commit message.

This is my commit message

Signed-off-by: John Doe <JohnDoe@somewhere.org>

Git has a -s option to append this automatically:

git commit -s -m 'This is my commit message'

If you have already made a commit and forgot to include the sign-off, you can amend your last commit:

git commit --amend -s

If you want to get in touch with us first before contributing, you can use:

• #strimzi channel on CNCF Slack
• Strimzi Dev mailing list

Container signatures

From the 0.38.0 release, Strimzi containers are signed using the cosign tool. Strimzi uses keyless signing since 0.49.0 release. To verify the container, you can run the following command:

cosign verify --certificate-identity-regexp='https://github.com/strimzi/.*' \
    --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
    quay.io/strimzi/operator:latest

In case you want to verify containers of older version of Strimzi than 0.49.0, then use our public key:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAET3OleLR7h0JqatY2KkECXhA9ZAkC
TRnbE23Wb5AzJPnpevvQ1QUEQQ5h/I4GobB7/jkGfqYkt6Ct5WOU2cc6HQ==
-----END PUBLIC KEY-----

And use it to verify the signature:

cosign verify --key strimzi.pub quay.io/strimzi/operator:latest --insecure-ignore-tlog=true

Software Bill of Materials (SBOM)

From the 0.38.0 release, Strimzi publishes the software bill of materials (SBOM) of our containers. The SBOMs are published as an archive with SPDX-JSON and Syft-Table formats signed using cosign. For releases, they are also pushed into the container registry.

Strimzi uses keyless signing since 0.49.0 release. To verify the SBOM signatures, you can run the following command:

cosign verify-blob --bundle <SBOM-file>.bundle \
    --certificate-identity-regexp='https://github.com/strimzi/.*' \
    --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
    <SBOM-file>

In case you want to verify SBOM signatures of older version of Strimzi than 0.49.0, then use our public key:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAET3OleLR7h0JqatY2KkECXhA9ZAkC
TRnbE23Wb5AzJPnpevvQ1QUEQQ5h/I4GobB7/jkGfqYkt6Ct5WOU2cc6HQ==
-----END PUBLIC KEY-----

You can use it to verify the signature of the SBOM files with the following command:

cosign verify-blob --key cosign.pub --bundle <SBOM-file>.bundle --insecure-ignore-tlog=true <SBOM-file>
