Helm Basics

Charts

We only support our own helm-charts. If you run anything outside the scope of our helm-charts, we cannot guarantee interoperability and you might run into issues we’re unable to support with resolving

Installing a Chart

If you want to install a chart using helm, lookup the name of the chart in our Chart list. Then, run this command to install it directly from our OCI repository:

Install Chart

   helm install mychart oci://tccr.io/truecharts/CHARTNAME

Where CHARTNAME is the name of the chart you want to add and mychart is the name you want it to have on your system.

We highly suggest your write your customisations and user specific options in your own values.yaml file. After which, you can install the chart with your user-specific settings applied using:

Install Chart With Settings

   helm install mychart oci://tccr.io/truecharts/CHARTNAME -f values.yaml

values.yaml can be replaced with a path of your choice.

We also advise users to specify separate namespaces for deployed charts using:

Chart Namespaces

   helm install mychart oci://tccr.io/truecharts/CHARTNAME -f values.yaml -n NAMESPACE

Where NAMESPACE is the namespace you want to deploy to.

For more information, please see the Helm install docs

Upgrading Charts

To upgrade either the chart version and/or the user-defined settings for an already-installed Helm chart you can use “helm upgrade”. While this does not actually update the chart version, it does update the user settings supplied via the values.yaml file specified above.

Chart Upgrades

   helm upgrade oci://tccr.io/truecharts/CHARTNAME -f values.yaml -n NAMESPACE

For more information, please see the Helm upgrade docs
