Quick Start

Learn how to get Keptn running in five minutes.

1. Create Kubernetes cluster

Select one of the following options:

Google Kubernetes Engine (GKE)

Run your Keptn installation for free on GKE! If you sign up for a Google Cloud account, Google gives you an initial $300 credit. For deploying Keptn you can apply for an additional $200 credit, which you can use towards that GKE cluster needed to run Keptn.

Install local tools
- gcloud

Create GKE cluster

Master version: 1.16.x and 1.17.x (tested version: 1.17.14-gke.400)
One node with 8 vCPUs and 32 GB memory (e.g., one n1-standard-8 node)
Change Image type from COS to Ubuntu (Note: In case you plan to use Dynatrace monitoring, we recommend Ubuntu for a more convenient setup.)
Sample script to create such a cluster:

// set environment variables
PROJECT=<NAME_OF_CLOUD_PROJECT>
CLUSTER_NAME=<NAME_OF_CLUSTER>
ZONE=us-central1-a
REGION=us-central1
GKE_VERSION="1.17"
IMAGE_TYPE="Ubuntu"

gcloud container clusters create $CLUSTER_NAME --project $PROJECT --zone $ZONE --no-enable-basic-auth --cluster-version $GKE_VERSION --machine-type "n1-standard-8" --image-type "$IMAGE_TYPE" --disk-type "pd-standard" --disk-size "100" --metadata disable-legacy-endpoints=true --scopes "https://www.googleapis.com/auth/devstorage.read_only","https://www.googleapis.com/auth/logging.write","https://www.googleapis.com/auth/monitoring","https://www.googleapis.com/auth/servicecontrol","https://www.googleapis.com/auth/service.management.readonly","https://www.googleapis.com/auth/trace.append" --num-nodes "1" --enable-stackdriver-kubernetes --no-enable-ip-alias --network "projects/$PROJECT/global/networks/default" --subnetwork "projects/$PROJECT/regions/$REGION/subnetworks/default" --addons HorizontalPodAutoscaling,HttpLoadBalancing --enable-shielded-nodes --no-enable-autoupgrade

K3s

Please refer to the official homepage of K3s for detailed installation instructions. Here, a short guide on how to run Keptn on K3s is provided for a Linux environment. Note: If you are using macOS, you will need to run K3s using multipass and as explained here.

Download, install K3s (tested with versions 1.16 to 1.19) and run K3s using the following command:
```
curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.19.5+k3s1 K3S_KUBECONFIG_MODE="644" sh -s - --no-deploy=traefik
```
This installs version v1.19.5+k3s1 (please refer to the K3s GitHub releases page for newer releases), sets file permissions 644 on /etc/rancher/k3s/k3s.yaml and disables traefik as an ingress controller.

Export the Kubernetes profile using

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml

Verify that the connection to the cluster works
```
kubectl get nodes   
```

Other K8s options

We also support installation on:

AWS Elastic Kubernetes Service (EKS)
Azure Kubernetes Service (AKS)
Minikube
OpenShift 4 & 3.11

For details on the specific providers, please visit our detailed installation guide.

2. Install Keptn

The following instructions will install the latest stable Keptn CLI (0.7.3) in a quick way.

If you need more information, please look at the install Keptn CLI guide.

2.1 Install Keptn CLI

The Keptn CLI is the one-stop-shop for all operations related to Keptn.

Please make sure you have kubectl installed (see kubernetes.io/docs/tasks/tools/install-kubectl).

2.1.1 Automatic install of the Keptn CLI using Bash

Note: This will work on Linux (and WSL2), as well as MacOS. Windows users need bash, curl and awk installed (e.g., using Git Bash).

This will download the latest stable Keptn version from GitHub, unpack it and move it to /usr/local/bin/keptn.
```
curl -sL https://get.keptn.sh | bash
```
Verify that the installation has worked and that the version is correct by running:
```
keptn version
```
or if you are on Windows
```
./keptn version
```

2.1.2 Manual install of the Keptn CLI

Download a release for your platform from the GitHub
Unpack the binary, rename and move it to a directory of your choice (e.g., /usr/local/bin/)
Verify that the installation has worked and that the version is correct by running:
```
keptn version
```

3. Install Keptn and authenticate Keptn CLI

By executing the keptn install command as shown next, Keptn will be installed on your Kubernetes cluster supporting all continuous delivery use cases (including quality gates and automated operations):
```
keptn install --use-case=continuous-delivery
```
After a successful installation, you need to expose Keptn. The official install Keptn CLI guide provides different ways of exposing your Keptn. In this quick start, the port-forwarding mechanism from Kubernetes is applied:
```
kubectl -n keptn port-forward service/api-gateway-nginx 8080:80
```

When Keptn is exposed, the CLI can get authenticated:

keptn auth --endpoint=http://localhost:8080 --api-token=$(kubectl get secret keptn-api-token -n keptn -ojsonpath={.data.keptn-api-token} | base64 --decode)

Finally, verify that Keptn is working by executing:
```
keptn status
```

🚀 Keptn is now ready to be used.

Access Keptn Bridge

By default, basic authentication is in place that protects the Keptn Bridge.

To get the user and password, execute the command:
```
keptn configure bridge --output
```
To get the enpoint your Keptn is running on, execute the command:
```
keptn status
```
Consequently, follow the provided endpoint link and remove api at the end to get to the Keptn Bridge that will prompt for user and password.

4. Explore tutorials to learn more about the Keptn use cases

With Keptn installed, have a look at the different tutorials to learn hands-on about the Keptn use cases:
