This helm chart deploys a deployment, with a series of services and ingresses for a given container, hosting a web service with the following properties:
- Configuration from environment variables
- exposes a number of ports, dependent on the container
The chart exposes port 8000 over http by default, with a load balancing service, but the ports and services are configured from a list of arbitrary length in the values file.
Similarly, the environment variables are injected from a definition list, of arbitrary length.
The goal is to provide a DRY microservice deployment mechanism with some flexibility, to be used with some other charts orchestrating a series of microservices via a requirement file, pointing to this chart, where each instance of this chart is differenciated using aliases.
The federating chart will provide the configuration for each microservices in its values file.
- Kubernetes cluster 1.10+
- Helm 3.0.0+
- PV provisioner support in the underlying infrastructure.
helm repo add cetic https://cetic.github.io/helm-charts
helm repo updateThe following items can be set via --set flag during installation or configured by editing the values.yaml directly (need to download the chart first).
- Ingress: The ingress controller must be installed in the Kubernetes cluster.
- ClusterIP: Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster.
- NodePort: Exposes the service on each Node’s IP at a static port (the NodePort). You’ll be able to contact the NodePort service, from outside the cluster, by requesting
NodeIP:NodePort. - LoadBalancer: Exposes the service externally using a cloud provider’s load balancer.
For other configurations, please see the values.yaml file. This file lists the configurable parameters of the microservice chart and the default values.
Install the microservice helm chart with a release name my-release:
