Install Knative

​​Businesses are modernizing and adopting multi-cloud approaches to deliver services. This shift in application deployment has given rise to containerization and Kubernetes for the deployment, management, and scaling of containerized applications. 

This course introduces you to serverless computing and shows you how to build serverless applications using Knative. It teaches CI/CD using Tekton and shows you how to build pipelines triggered by GitHub events. You will create a pipeline that builds container images using Build and, later, Cloud Native Buildpacks. 

In the last part of the course, you will build a web application that integrates with GitHub using a GitHub App, and triggers application build and deployment in response to GitHub events.

Building a Serverless App Platform on Kubernetes

## Tekton Pipelines

In this lesson, we’ll work with Tekton Pipelines, Triggers, and Dashboard. To install Tekton Pipelines on our Kubernetes cluster, follow these steps:

1. Use the first command given in the `1_installTekton.sh` file to install Tekton Pipelines and its dependencies.


2. Use the second command given in the `1_installTekton.sh` file to monitor the installation. Monitor it until all the components show a `Running` status, and then press “CTRL+C” (or “control + C” on macOS) to stop monitoring.

The result of the command should look like this:

```
NAME                             READY   STATUS    RESTARTS   AGE
tekton-pipelines-controller-76   1/1     Running   0          25s
tekton-pipelines-webhook-fc      1/1     Running   0          25s
```


We’ve successfully installed Tekton Pipelines on our Kubernetes cluster. Next, we need to install Tekton Triggers.


## Tekton Triggers

Follow the instructions below to install it:

1. Use the first two commands given in the `2_tektonTriggers.sh` file to install Tekton Triggers and its dependencies.


2. Use the third command given in the `2_tektonTriggers.sh` file to monitor the installation. When all the components of Tekton Triggers report a `Running` status, press “CTRL+C” (or “control + C” on macOS) to stop monitoring.
