How to install or upgrade a chart release

1. Get the values file of the Cloudflare DDNS chart or an existing installation (release).

   Get the latest Cloudflare DDNS chart values file for a new installation:

   helm show values mika/cloudflareddns > values.yaml

   Alternatively, get the values file of an existing Cloudflare DDNS release:

   helm get values ${releaseName} --namespace ${namespace} > values.yaml

   Replace ${releaseName} and ${namespace} accordingly.

2. Edit your Cloudflare DDNS values file with the intended configurations:

   nano values.yaml

   Pay extra attention to the descriptions and sample values provided in the chart values file.

3. Install a new release for Cloudflare DDNS or upgrade an existing Cloudflare DDNS release:

   helm upgrade --install ${releaseName} mika/cloudflareddns --namespace ${namespace} --create-namespace --values values.yaml --wait

   Replace ${releaseName} and ${namespace} accordingly.

4. Verify that your Cloudflare DDNS release has been installed:

   helm ls --namespace ${namespace} | grep "${releaseName}"

   Replace ${namespace} and ${releaseName} accordingly. This should return the release information if the release has been installed.

How to uninstall a chart release

Caution

Uninstalling a release will irreversibly delete all the resources associated with the release, including any persistent data.

1. Uninstall the desired release:

   helm uninstall ${releaseName} --namespace ${namespace} --wait

   Replace ${releaseName} and ${namespace} accordingly.

2. Verify that the release has been uninstalled:

   helm ls --namespace ${namespace} | grep "${releaseName}"

   Replace ${namespace} and ${releaseName} accordingly. This should return nothing if the release has been uninstalled.
