*Intelligently manage your Kubernetes manifest files
*Manage releases of Helm packages
== Examples ==
Assuming you already have Helm installed and you have a running Kubernetes cluster (start out with [[minikube]]), you could issue the following to "install" the MediaWiki application (chart) offered by Bitnami (as contained in the docker.io registry). The name of the application (called a "release") would be "my-release".<br />
<code>helm install my-release oci://registry-1.docker.io/bitnamicharts/mediawiki</code>
This would produce output like the following:
<pre>
Pulled: registry-1.docker.io/bitnamicharts/mediawiki:21.0.3
Digest: sha256:43a905d16c40c05f290b6e19db684dfe2d75677f3a6c7ce1c0b3ac81897beb9c

This deployment will be incomplete until you configure Mediawiki with a resolvable
host. To configure Mediawiki with the URL of your service:
1. Get the Mediawiki URL by running:
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
Watch the status with: 'kubectl get svc --namespace default -w my-release-mediawiki'
export APP_HOST=$(kubectl get svc --namespace default my-release-mediawiki --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
export APP_PASSWORD=$(kubectl get secret --namespace default my-release-mediawiki -o jsonpath="{.data.mediawiki-password}" | base64 -d)
export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default my-release-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
export MARIADB_PASSWORD=$(kubectl get secret --namespace default my-release-mariadb -o jsonpath="{.data.mariadb-password}" | base64 -d)
2. Complete your Mediawiki deployment by running:
helm upgrade --namespace default my-release oci://registry-1.docker.io/bitnamicharts/mediawiki \
--set mediawikiHost=$APP_HOST,mediawikiPassword=$APP_PASSWORD,mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD,mariadb.auth.password=$MARIADB_PASSWORD
2. Get your MediaWiki login credentials by running:
echo Username: user
echo Password: $(kubectl get secret --namespace default my-release-mediawiki -o jsonpath="{.data.mediawiki-password}" | base64 -d)
WARNING: There are "resources" sections in the chart not set. Using "resourcesPreset" is not recommended for production. For production installations, please set the following values according to your workload needs:
- resources
