Zookeeper

Deploy custom Kubernetes compliant Zookeeper image (extended from Kubernetes Zookeepper) with added features:

  • Publish json formatted logs for easy consumption by EFK stack

This image can be run in any container platform

Customization

  • Refer the custom jar in extra_lib. This will format logs into Json format.
  • Modified Log4j properties are in conf
  • bin\start-zookeeper is modified to not use the existing log4j properties file

Test locally

  • Build image: docker build -t anair/zookeeper:3.4.10-1 .
  • Create new project in minishift
  • Deploy k8s/zookeeper-sts.yaml stateful set to create a 3 pod zookeeper cluster
  • Verify logs are in json format
