NATS

NATS is an open-source, cloud-native messaging system.

Upgrading operator

This step is only necessary in case of installing a backward incompatible operator version. Otherwise, simply upgrade the operator using helm.

• Remove the server and operator first.

helm delete nats-operator --purge
helm delete nats --purge

• Then remove the CRDs.

kubectl delete crd natsserviceroles.nats.io
kubectl delete crd natsclusters.nats.io

Fresh install

• Create the following yaml config(values) file.

clusterScoped: true
cluster:
  create: false

• Install the operator

helm install dictybase/nats-operator --version 0.1.3 -f dev.yaml --name nats-operator --namespace nats-io

• Make sure the operator is deployed

kubectl get crd | grep nats

• Install the server

helm install dictybase/nats --version 0.0.3 --name nats --namespace dictybase

Extra sauce (syncing the operator chart)

The operator chart in the dictybase helm repository is packaged from the upstream repository. To keep it updated do the following steps,

• Clone the dictybase helm chart repository

git clone git@github.com:dictybase-docker/kubernetes-charts.git

• Clone the nats-operator repository and change to appropiate folder

git clone https://github.com/nats-io/nats-operator.git
cd nats-operator

• Make necessary changes
• Package the chart and copy the tarball to the docs folder of dictybase helm chart repository

helm package .

• Go back to the dictybase helm chart repository and update the package index

helm repo index docs

• Commit and push the changes.
• Synchronize the changes with helm client.

helm repo update
