Deploy abcdesktop on DigitalOcean with Kubernetes

Requirements

  • a DigitalOcean account
  • kubectl
  • doctl command line interface doctl cli

If you doctl command line for your first time, run doctl auth command line for use with your DigitalOcean account using tokens that you generate in the control panel at https://cloud.digitalocean.com/account/api/tokens.

Create a DOKS DigitalOcean Kubernetes cluster

If you don't have a running kubernetes cluster, run the doctl command line with the kubernetes cluster create to create your cluster.

doctl kubernetes cluster create --node-pool 'auto-scale=true;size=s-4vcpu-8gb;min-nodes=3;max-nodes=5' myabccluster
  • auto-scale: Enables cluster auto-scaling on the node pool.
  • region: The default region is "nyc1" regional availability
  • min-nodes: 3 nodes min for auto-scaling
  • max-nodes: 5 nodes max for auto-scaling
  • size: s-4vcpu-8gb gets 4 shared vCPU, 8 GB vRAM, 160 GB Storage

After few minutes, you get a kubernetes cluster ready

Check your kubernetes config file

Run a kubectl command line like kubectl cluster-info command line to make sure that kubeconfig has been updated by doctl command.

kubectl cluster-info

The kubectl cluster-info results

Kubernetes control plane is running at https://83aae84d-cfa9-4a89-ae75-89f0d5078d33.k8s.ondigitalocean.com
CoreDNS is running at https://83aae84d-cfa9-4a89-ae75-89f0d5078d33.k8s.ondigitalocean.com/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

Run the abcdesktop install script

Download and install the latest release automatically

curl -sL https://raw.githubusercontent.com/abcdesktopio/conf/main/kubernetes/install-4.1.sh | bash

To get more details about the install process, please read the Setup guide

Connect to your abcdesktop service

By default install script is listening on a free tcp port :30443 and is using a kubectl port-forward command line to reach http web service :80

Open your web browser http://locahost:30443

abcdesktop login

Login as user Philip J. Fry with the password fry

abcdesktop login as fry

After image pulling process, you get your first abcdesktop

abcdesktop for fry

Add applications to your desktop

Using the previous terminal shell, run the application install script 

curl -sL https://raw.githubusercontent.com/abcdesktopio/conf/main/kubernetes/pullapps-4.1.sh | bash

To get more details about the install applications process, please read the Setup applications guide

Then reload the web page with the desktop of Philip J. Fry New applications are now listed in the dock of plasmashell.

Start Firefox application

The first run may involve waiting for the image pulling process to finish

Go to https://mylocation.org website to check where your pod is running. In my case for the region nyc1 (New york City 1), the desktop is located near North Bergen city in United States.
