CKAN Helm Chart

A Helm chart for CKAN

Current chart version is 1.0.1

This chart deploys a self contained CKAN instance with all of its dependencies. These can be enabled/disabled if they already exist in your infrastructure.

Two jobs for initializing Postgres and SOLR can also be enabled through the values. These will use the provided CKAN environment to set the access permissions for the ckan and datastore DB users as well as create a SOLR collection for the CKAN instance.

Prerequisites Details

• Kubernetes 1.9
• Install Helm
• Setup correctly kubectl and kubeconfig setup before running helm.

Helm repo

The datapusher and ckan charts can be found on Keitaro's helm repo:

$ helm repo add keitaro-charts https://keitaro-charts.storage.googleapis.com

Deploy CKAN on kubernetes cluster

To deploy CKAN on kubernetes cluster with the release name <release-name>:

$ helm repo add keitaro-charts https://keitaro-charts.storage.googleapis.com
$ helm install <release-name> keitaro-charts/ckan

Configuration

Production deployment values can be set in values.yaml here. This file contains variables that will be passed to the templates. All configurable values should be placed in this file. Alternatively, you can specify each parameter using the --set key=value[,key=value] argument to helm install.

Cleanup

To remove the spawned pods you can run a simple helm delete <release-name>. Helm will however preserve created persistent volume claims, to also remove them execute the commands below.

$ release=<release-name>
$ helm delete $release
$ kubectl delete pvc -l release=$release
