DigitalOcean Kubernetes (DOKS)

This guide will show you how to install Okteto onto DigitalOcean Kubernetes. We'll be focusing exclusively on DigitalOcean Kubernetes in order to keep it as simple as possible.

Requirements​

In order to fully install Okteto, you'll need the following:

  • A subdomain to which you can add a wildcard DNS record
  • A Kubernetes cluster
  • A working installation of kubectl
  • A working installation of Helm v3 (v3.8 or higher)
  • An Okteto License

Subdomain​

You'll need sufficient access to a subdomain to add a wildcard DNS record, such as dev.example.com. By default, all endpoints created by Okteto for your development environments will be exposed on the wildcard subdomain you choose.

This guide assumes your domain is registered in DigitalOcean Domains. You can use any DNS service you prefer, but this guide focuses specifically on DigitalOcean Domains.

Deploy a Kubernetes cluster​

If you are not familiar with this step, we recommend that you follow DigitalOcean's cluster creation guide. Okteto supports Kubernetes versions 1.24 through 1.26.

To get started with Okteto, follow these specs:

  • v1.26
  • A pool with at least 3 nodes (4CPUs and 16GBs each)
  • 250 GB per disk

You'll be using the cluster's API server endpoint when configuring Okteto. Run the following command to obtain your cluster's API server endpoint:

kubectl config view --minify | grep server

Our installation guides assume Okteto will be running in a dedicated cluster. We recommend contacting our team if you plan on installing Okteto in a cluster with other workloads.

Installing kubectl​

Follow the official documentation for installing kubectl. Once installed, configure kubectl to talk to your new cluster.

Installing Helm v3 (v3.8 or higher)​

Follow the official documentation for installing the latest release of Helm v3 (v3.8 or higher).

Adding the Okteto Helm repository​

You'll need to add the Okteto repository in order to be able to install Okteto:

helm repo add okteto https://charts.okteto.com
helm repo update

Getting your Okteto License​

You'll receive a license key as part of your subscription to Okteto. If you haven't received it, please open a support ticket.

Installing Okteto​

Download a copy of the Okteto DigitalOcean configuration file, open it, and update the following values:

  • Your license
  • A subdomain
  • Your cluster's API server endpoint

For example:

license: 1234567890ABCD==
subdomain: dev.example.com
cluster:
  endpoint: "https://XXXXXX.aks.microsoft.com"

buildkit:
  persistence:
    enabled: true

registry:
  storage:
    filesystem:
      persistence:
        enabled: true

Installing your Okteto instance​

Install the latest version of Okteto by running:

helm install okteto okteto/okteto -f config.yaml --namespace=okteto --create-namespace

You can also install a specific version by including the --version argument.

After a few seconds, all the resources will be created. The output will look something like this:

Release "okteto" has been installed. Happy Helming!
NAME: okteto
LAST DEPLOYED: Thu Mar 26 18:07:55 2020
NAMESPACE: okteto
STATUS: deployed

Retrieve the Ingress Controller IP address​

You can use kubectl to fetch the address that has been dynamically allocated by DigitalOcean to the NGINX Ingress you've just installed and configured as a part of Okteto:

kubectl get service -l=app.kubernetes.io/name=ingress-nginx,app.kubernetes.io/component=controller --namespace=okteto

The output will look something like this:

NAME                             TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)                                     AGE
okteto-ingress-nginx-controller  LoadBalancer   10.245.147.23  64.225.83.163   80:30087/TCP,443:31799/TCP,1234:31412/TC    2m

You'll need to take the EXTERNAL-IP address, and add it to your DNS for the domain you have chosen to use. This is done by creating an A record with the name *.

Sign in to your Okteto instance​

After a successful installation, you can access your Okteto instance at https://okteto.SUBDOMAIN. Your account will be automatically created as part of the login process. The first user to successfully login into the instance will be automatically assigned the administrator role.

Important: The default installation is not recommended for production use. We highly advise following the steps outlined in the Admin Dashboard before giving your team access to your Okteto instance.

The default installation is all that's required to follow our getting started guide.
