Suggest replacing Bitnami Kafka images with free, Bitnami-compatible alternatives

[igor-soldev]

Hi,

Several files in the repository reference Bitnami Kafka images, for example:

applications/openim/errcode/openIM/templates/job-kafka.yaml

applications/openim/errcode/manifests/openIM.yaml

applications/milvus-operator/latest/init.sh

applications/bitnami-kafka/latest/init.sh

These use images such as:
image: docker.io/bitnami/kafka

Since Bitnami has recently restricted access to many of their container images, these references may cause pull failures during image builds or when generating cluster images.

A free, Bitnami-layout-compatible Kafka image could be used as a drop-in replacement.
For example, soldevelo/kafka keeps the expected /bitnami/... filesystem structure, runs as non-root, and tracks upstream Kafka versions.

Link: https://hub.docker.com/r/soldevelo/kafka

If maintainers find this appropriate, I can prepare a PR updating the Kafka image references across the affected files.

Just a reminder about this.

This is an important issue, as the current setup is effectively broken for anyone without a Bitnami subscription. Do you have any plans to address this, or would you like me to proceed with a PR?
