It is a repository with Helm charts for Apache NiFi and Apache NiFi Registry.
Blog Post about NiFi on Kubernetes.
This repo is constantly being improved.
You need the following components to use these Helm charts:
- Kubernetes cluster (1.15 and newer)
- Helm 3
Tested with the following Ingress:
- NGINX Ingress Controller Here we use featured SSL Passthrough.
You can find CI pipelines for two CICD tools: GitLab CI and GitHub Actions.
- GitLab CI: .gitlab-ci.yml
- GitHub Actions: directory .github/workflows
Create your values file or use the default one.
Apache NiFi:
helm --namespace nifi nifi upgrade --install ./apache-nifi/chart -f ./apache-nifi/chart/values.yamlApache NiFi Registry:
helm --namespace nifireg nifi upgrade --install ./apache-nifi-registry/chart -f ./apache-nifi-registry/chart/values.yamlThe following table lists the configurable parameters of the Apache NiFi chart and the default values.
