Install KLT

Two methods are supported for installing the Keptn Lifecycle Toolkit:

• Releases v0.7.0 and later can be installed using the Helm Chart. This is the preferred strategy because it allows you to customize your cluster.

• All releases can be installed using the manifests. This is the less-preferred way because it does not support customization.

Use Helm Chart

Version v0.7.0 and later of the Lifecycle Toolkit should be installed using Helm Charts. The command sequence to fetch and install the latest release is:

helm repo add klt https://charts.lifecycle.keptn.sh
helm repo update
helm upgrade --install keptn klt/klt \
   -n keptn-lifecycle-toolkit-system --create-namespace --wait

Note that the helm repo update command is used for fresh installs as well as for upgrades.

Use the --version <version> flag on the helm upgrade --install command line to specify a different KLT version.

Use the following command sequence to see a list of available versions:

helm repo update
helm search repo klt

To modify configuration options, download a copy of the helm/chart/values.yaml file, modify some values, and use the modified file to install KLT:

1. Download the values.yaml file:

   helm get values RELEASE_NAME [flags] > values.yaml
   

2. Edit your local copy to modify some values

3. Install KLT by adding the following string to your helm upgrade command line:

   --values=values.yaml
   

You can also use the --set flag to specify a value change for the helm upgrade --install command. Configuration options are specified using the format:

--set key1=value1,key2=value2,....

For more information,see

• The Helm Get Values) document

• The helm-charts page contains the full list of available values.

Use manifests

All versions of the Lifecycle Toolkit can be installed using manifests, although we recommend that you use Helm Charts to install Version 0.7.0 and later because the Helm Charts allow you to customize your configuration.

Versions 0.6.0 and earlier can only be installed using manifests.

Note When installing Version 0.6.0, you must first install the cert-manager with the following command sequence:

kubectl apply \
   -f https://github.com/cert-manager/cert-manager/releases/download/v1.11.0/cert-manager.yaml
kubectl wait \
   --for=condition=Available deployment/cert-manager-webhook -n cert-manager --timeout=60s

Use a command sequence like the following to install the Lifecycle Toolkit from the manifest, specifying the version you want to install.

kubectl apply \
   -f https://github.com/keptn/lifecycle-toolkit/releases/download/v0.6.0/manifest.yaml
kubectl wait --for=condition=Available deployment/lifecycle-operator \
   -n keptn-lifecycle-toolkit-system --timeout=120s

The Lifecycle Toolkit and its dependencies are now installed and ready to use.
