limits the length of the grafana dashboard uid to 40 to prevent grafa…

…na import error

When trying to import the dashboard json the grafana container throws logger=provisioning.dashboard type=file name=file t=2024-05-23T06:54:30.144967684Z level=error msg="failed to save dashboard" file=/tmp/dashboards/fluentbit-fluent-bit-fluent-bit.json error="uid too long, max 40 characters"

With this fix the length of the uid is trunctated to 40 chars.

Isn't the output of sha256sum fixed length?

It is fixed to 64 chars and so too long for grafana

hi, can we remove this imp. , I was using old Grafana where if I set uid null not generating unique uid. After upgrading Grafana if we pass null it is working.

Would be great to get this fix in or as an alternative we simply do not define the uid in the dashboard. Both solutions work, tested in my own setup.

@mheers could you please update this PR to set the uid field to null and remove the fluent-bit.dashboard.uid function added in #503.

[mheers]

@stevehipwell done

[stevehipwell]

@mheers could you rebase this PR?

[mheers]

@stevehipwell rebased and cleaned history

[marcofranssen]

@mheers the dco is failing. Maybe fix that to not delay the release of this fix

[mheers]

@marcofranssen fixed. thanks

[stevehipwell]

@mheers you need to update the version and release notes annotations in Chart.yaml so the workflows will pass.

[mheers]

@stevehipwell updated
