requirements

• kind
• helm at least 3.7.0 version
• go

run

• modify values.yml if needed and run make run start kind cluster
• cluster runs test log-app exposed on 30500 port, which can be used to generate logs by POSTing data to it:
  • curl -v -X POST -d 'test log message' http://localhost:30500
• logs are sent to /tmp/fluent-bit-test/ local directory
  • tail -f /tmp/fluent-bit-test/kube.var.log.containers.log-app-*.log | jq .
• project is also configured with out-plugin written in go. To view the output from this plugin, run:
  • tail -f /tmp/fluent-bit-test/out
• clean up after test make cleanup

debug kind cluster

• docker ps - list kind cluster nodes running as docker images
• docker exec -it fluent-bit-test-control-plane bash - "ssh" onto control plane node
• once on the node, we can:
  • ps auxf check processes
  • crictl images check images already present on the node
