@stefanprodan is anything that I can help, for us to make progress with this PR?

[stefanprodan]

@rinormaloku this looks good, we're working on the next patch release for Flagger then we'll review your PR. I expect this to be included in the next minor release.

[rinormaloku]

Sounds good! :))

[stefanprodan]

You need to add gloomesh to the e2e test suite here https://github.com/fluxcd/flagger/blob/main/.github/workflows/e2e.yaml

[rinormaloku]

@stefanprodan I didn't add it to the e2e suite as Gloo Mesh requires a license and currently and it would require rotating the license frequently

[mrajkarnikar]

@stefanprodan any update on this

[stefanprodan]

@rinormaloku @mrajkarnikar in the past we've rejected integrations with non OSS tools like Kong ingress. Having this integration in Flagger with no means of testing it automatically is not something that I would consider.

[...] Having this integration in Flagger with no means of testing it automatically is not something that I would consider.

If we provide a secret, would you be able to securely store it and make it available to the script as an Environment Variable?

[stefanprodan]

Using secrets in tests means we can no longer run them on PRs. If someone breaks this integration, we can't tell until we merge the PR when it's too late. The whole purpose of testing is to validate the changes before they get merged. Also what happens when they key expires?

[mrajkarnikar]

@stefanprodan so flagger will never integrate with non oss tool? Should we be closing this PR then?
