Fix sidekiq gem warnings ⚠️

Since redis-rb gem version higher than 4.2.0 will generate lots of warnings (as redis-namespace issue in the past) a sidekiq gem was updated in the Docker image to the latest stable version 6.2.1 which will contain also fix for new redis-rb behavior.

Thanks @RanAbram and @scottcrossen for the support 💛

Fix sidekiq-namespace gem warnings ⚠️

In this release, a very annoying warning about a wrong method name was removed. It was done by updating the sidekiq-namespace gem to the latest version 1.8.1.

Many thanks to @RanAbram for pointing out 💜

So starting this release it should be quiet inside the Docker containers 🤫

A new env variable for the Docker image

This is a meta release, only a Docker image, and a Helm package is updated. Thanks to @Namrata3991 for raising the issue and @ajinkyapisal for the fix.

In Docker image 0.1.15-1 if you are using a secure connection to the Redis you can set REDIS_SSL to true and the exporter application will start using rediss:// scheme instead of just redis://.

Happy exporting ❤️

Add new env variable to Docker image

In this release, an important env variable was added to the docker image REDIS_DISABLE_CLIENT_ID. This flag will disable a CLIENT command in Sidekiq, which might be required if a SaaS Redis provider is being used.

Thanks to @ckoenig 🧡 for this feature!

Fix Docker image Redis URL with password

Thanks to @dcd000 for spotting issue #33 💙

Rack 2.2+ support

Since Rack 2.2.0 response headers will always contain ETag value even if you set Cache-Control: no-cache. This implies that headers will be mutated and it will lead to issue #21

Starting this version it's not a case anymore, many thanks @sobels for the finding 👏 🎉
