Installing Tekton Triggers

Use this page to add the component to an existing Kubernetes cluster.

Pre-requisites

A Kubernetes cluster version 1.15 or later (if you don't have an existing cluster):

# Example cluster creation command on GKE
gcloud container clusters create $CLUSTER_NAME \
  --zone=$CLUSTER_ZONE

Grant cluster-admin permissions to the current user:

kubectl create clusterrolebinding cluster-admin-binding \
--clusterrole=cluster-admin \
--user=$(gcloud config get-value core/account)

See Role-based access control for more information.

Install Tekton Pipelines. You can install the latest version using the command below or follow the pipeline installation guide:
```
kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml
```

The versions of Tekton Triggers available are:

Officially released versions, e.g. v0.1.0
HEAD - To install the most recent, unreleased code in the repo see the development guide

To add the Tekton Triggers component to an existing cluster:

Run the kubectl apply command to install Tekton Triggers and its dependencies:
```
kubectl apply --filename https://storage.googleapis.com/tekton-releases/triggers/latest/release.yaml
```
Previous versions will be available at previous/$VERSION_NUMBER, e.g. https://storage.googleapis.com/tekton-releases/triggers/previous/v0.1.0/release.yaml
Run the kubectl get command to monitor the Tekton Triggers components until all of the components show a STATUS of Running:
```
kubectl get pods --namespace tekton-pipelines
```
Tip: Instead of running the kubectl get command multiple times, you can append the --watch flag to view the component's status updates in real time. Use CTRL + C to exit watch mode.

You are now ready to create and run Tekton Triggers:
