⁠Container Image for Connect Install Tools

The Container image contains tools for installing Connect plugins like Connectors to the ueisele/apache-kafka-connect-base⁠, ueisele/apache-kafka-connect⁠ and ueisele/apache-kafka-connect-standalone⁠ images.

The Container images are available on Docker Hub repository ueisele/apache-kafka-connect-plugin-install⁠, and the source files for the images are available on GitLab repository ueisele/kafka-images⁠.

⁠Image
