@aryan9600 you probably want to have a look at this, and make suggestions if it does not combine well with your proposed changes in #605. |
This adds a Unix suffix to the HelmChart Artifact filename, to ensure it is unique for sequential builds triggered due to e.g. a controller restart. The result of this is that consumers who _think_ they are fetching an Artifact with a certain checksum run into a 404 when attempting to download a previously advertised but now unavailable file, instead of running into a checksum validation error (due to non-repetitive Helm builds). For more information, see: #610 Signed-off-by: Hidde Beydals <[email protected]>

This will break signature verification for cached charts (ref: #605). The chart name should be exactly how it's mentioned in it's provenance file, i.e. name-version.tgz. We could probably get around this by adding a symlink linking name-version-ts.tgz to name-version.tgz.

Was afraid this would be the case. Ack, I'll give it another shot when #605 is merged to get a better view on the options available then.

We should go ahead and merge this now, because of: #605 (comment)
Converting PR to draft, as this is being put on hold until we reach GA (ref: fluxcd/flux2#2592)

I would rather like to come up with a solution first that works for #605, as otherwise we're shooting ourselves in the foot with premeditation.

Potentially fixes #610
