nit: Can you fix the language above too? This is the kubernetes tail log file input.

I think what this is meant to do is to append to the kubernetes tail input. Because when I do a simple silly test:

$ helm template --dry-run . --set input.extraInputs="[INPUT]somekey someval"
...

  fluent-bit.conf: |
    [SERVICE]
        Parsers_File /fluent-bit/parsers/parsers.conf

    [INPUT]
        Name              tail
        Tag               kube.*
        Path              /var/log/containers/*.log
        DB                /var/log/flb_kube.db
        Parser            docker
        Docker_Mode       On
        Mem_Buf_Limit     5MB
        Skip_Long_Lines   On
        Refresh_Interval  10
        [INPUT]somekey someval

The new data is added indented to the existing tail input. So you could use this to set other values in it, like for example Ignore_Older:

$ helm template --dry-run . --set input.extraInputs="Ignore_Older 1d"
  fluent-bit.conf: |
    [SERVICE]
        Parsers_File /fluent-bit/parsers/parsers.conf

    [INPUT]
        Name              tail
        Tag               kube.*
        Path              /var/log/containers/*.log
        DB                /var/log/flb_kube.db
        Parser            docker
        Docker_Mode       On
        Mem_Buf_Limit     5MB
        Skip_Long_Lines   On
        Refresh_Interval  10
        Ignore_Older 1d

I think this was added because the input.* only allows you to customize a few things: https://github.com/aws/eks-charts/blob/master/stable/aws-for-fluent-bit/values.yaml#L29

So basically, the name here is wrong/misleading. It should be something like input.extraSettings.

I think the additionalInputs key is for adding other other inputs.

I don't know how this works- can we bump the chart version and change the setting name?

If not, can you please make the help text here much more clear: "Append other config options to the kubernetes tail input" something like that.

Thanks @PettitWesley - While I understand your points, I simply wanted to correct a typo in the readme. The functionality and naming therein should be out of scope for this, right? At least people working with the current version will then not make the same mistake I did, as the name will be correct.

Imo all of the names need to be reworked, because they're not consistent and are all confusing:

• service.extraParsers
• input.*
• extraInputs
• additionalInputs
• filter.*
• filter.extraFilters
• additionalFilters

Unfortunately I don't have time right now to devote to such a PR, however 😅

Fair point. I still think the language in your PR needs to be edited even just for this option. It should be clear what "existing input" means.

Append to existing kubernetes log file tail input with this value

would be prefered by me

there is also another issue here that the CI only lets you merge updates that change the chart version, which I'll have to look into.
