Which chart to use?

[pierluigilenoci]

We are planning the migration to the use of Helm Hub in our clusters and we wanted to understand which is the best version of Chart for Fluent-bit. The "historical" chart [1] seems to me more complete and maintained than the one present here.

I especially ask @edsiper who seems to be involved in both.

The "stable" chart will not be maintained for long so if you can I would recommend using the new chart. If anything is missing feel free to open an issue or a PR 😃

To briefly summarize the missing features that I see here (but maybe I simply overlooked)

• No explicit PodSecurityPolicy
• No default support for Audit (/var/log/kube-apiserver-audit.log)

After having better studied the chart I can understand the will to redo it from scratch but I suggest the creation of a migration guide between chart. It was challenging to figure out how.

I will put my hands on it and if I can I will see how to contribute.

#8 is open so PSP coming soon.

That is true, please use extraVolumes and extraVolumeMounts today. If this mounting is common enough we can either enable it by default or create an explicit value for it, this can be discussed in an issue.

💯 true. I have not had the bandwith to create a migration guide. If you could contribute yours that would be great. The gist of it would be:

• Copy contents of running config of stable/fluent-bit and paste blocks into the appropriate nested values of config for fluent/fluent-bit
• Mount any extra volumes such as tls certs by means of extraVolumes and extraVolumeMounts

I will put my hands on it and if I can I will see how to contribute.

As you can see I created one issue for audit logs and one for the migration guide. I suggest closing this topic.
