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.
- Kubernetes 1.9
- Install Helm
- Setup correctly kubectl and kubeconfig setup before running helm.
The datapusher and ckan charts can be found on Keitaro's helm repo:
$ helm repo add keitaro-charts https://keitaro-charts.storage.googleapis.comTo 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/ckanProduction 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.
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| Repository | Name | Version |
