New image tag for elasticsearch clients 7.x

[rsicart]

Hi @monotek

Actually I send logs to an Elasticsearch server (7.17.4) that I don't manage.

This morning I wanted to use the latest image v4.1.0 (built after #10) because I need a recent version of fluent-plugin-kubernetes_metadata_filter (2.11.1), but I get those errors:

The client is unable to verify that the server is Elasticsearch. Some functionality may not be compatible if the server is running an unsupported product.
2022-07-06 08:51:04 +0000 [error]: config error file="/etc/fluent/fluent.conf" error_class=Fluent::ConfigError error="Using Elasticsearch client 8.3.0 is not compatible for your Elasticsearch server. Please check your using elasticsearch gem version and Elasticsearch server."

From that error I understand that I should use an elasticsearch client 7.x (until the server is updated).

Could be possible to have an image tag which installs elasticsearch client 7.x along with fluent-plugin-kubernetes_metadata_filter 2.11.1? For example a new image tag 3.5?

Please let me know if it is possible

Thanks in advance!

I dont want to relase a downgrade so you would have to to fork, build and publish your own image...

Well, that's unfortunate.

That would be also an upgrade for tags 3.x, not only a downgrade.

Could you please reconsider, just a little docker push with those versions.... 😄

Well, if there's nothing to do we can close this issue.

Thanks anyways!
