An intentionally complex fibonacci calculator requiring multiple services, deployed through DigitalOcean Kubernetes
You can use the init-doks.sh file to initialize your DOKS (DigitalOcean Kubernetes) cluster and deploy the application. You need to
run the series of following commands when cluster provisioning is complete
chmod +x init-doks.sh # give execute permission
doctl auth init # authorize DO access with access token
./init-doks.sh <doks_cluster_id>
The script will setup everything. Please note, a CI/CD pipeline is also created with Github Actions. But to make the CI/CD
pipeline work properly, either you have to run this init-doks.sh file or configure the cluster manually (first-time only).
We can easily switch config context and directly interact with the DO cluster using kubectl commands. Follow this guide
In short, need to run the series of commands
doctl kubernetes cluster kubeconfig save use_your_cluster_name // save cluster config locally
kubectl config get-contexts // see all contexts, the new DO context should be available
kubectl use-context <context_name> // for switching contexts back and forth
Alternatively, at the time of writing this, DO Kubernetes also shows a getting started guide after creating a DOKS cluster, where you can find the necessary set of commands to set and switch contexts (Recommended approach)
At this point, your kubernetes config should be switched and you can run any kubectl command in your DOKS cluster. To create a secret for Postgres password:
kubectl create secret generic pgpassword --from-literal PGPASSWORD=1234asdf
A simple CI/CD pipeline has been created with Github Actions. You can check the Deploy workflow for more details
