Install On Digital Ocean

Digital Ocean is a cloud infrastructure provider which provides also managed Kubernetes cluster services. You can install KintoHub on Digital Ocean start with the cheapest tier (single node with 1GB of memory without LoadBalancer).

Create your Kubernetes Cluster on Digital Ocean

Visit the Digital Ocean documentation to create a Kubernetes cluster.
Once everything is setup you should be able to access the Kubernetes cluster with kubectl.

Install Cert Manager

Install Cert Manager from our installation guide if you require auto TLS certificate for your exposed services.

Install Argo Workflow

kubectl create namespace argo

helm repo add argo https://argoproj.github.io/argo-helm

helm upgrade --install argo \

--version 0.16.6 \

--set installCRD=true \

--set singleNamespace=false \

--set useDefaultArtifactRepo=true \

--set artifactRepository.archiveLogs=true \

--set artifactRepository.s3.accessKeySecret.name=kinto-minio \

--set artifactRepository.s3.accessKeySecret.key=accesskey \

--set artifactRepository.s3.secretKeySecret.name=kinto-minio \

--set artifactRepository.s3.secretKeySecret.key=secretkey \

--set artifactRepository.s3.insecure=true \

--set artifactRepository.s3.bucket=argo-artifacts \

--set artifactRepository.s3.endpoint=kinto-minio:9000 \

--set artifactRepository.minio.install=false \

--set controller.containerRuntimeExecutor=kubelet \

--namespace argo argo/argo

It is similar to our installation guide to install Argo Workflow, except we need to have the flag --set controller.containerRuntimeExecutor=kubelet on, since Digital Ocean is using the latest Kubernetes version (1.20+).

Install KintoHub

The installation is identical to installation guide or advanced installation guide. For the example below, it will create a secured dashboard with token authentication, exposing everything publicly, and everything services deployed are secured with TLS. (* This will create a Load Balancer which charges $10 per month)

Change the values inside the curly braces and run

kubectl create ns kintohub

helm repo add kintohub https://kintoproj.github.io/kinto-helm

helm upgrade --install kinto \

--set common.domainName={your_domain} \

--set common.ssl.enabled=true \

--set common.ssl.issuer.email={ssl_issuer_email} \

--set common.ssl.issuer.solver.cloudflare.email={cloudflare_account_email} \

--set common.ssl.issuer.solver.cloudflare.cloudflareApiToken={cloudflare_api_token} \

--set minio.resources.requests.memory=null \

--set minio.makeBucketJob.resources.requests.memory=null \

--set builder.env.IMAGE_REGISTRY_HOST={registry_host} \

--set builder.workflow.docker.registry={docker_registry_fqdn} \

--set builder.workflow.docker.email={docker_registry_email} \

--set builder.workflow.docker.username={docker_registry_account_username} \

--set builder.workflow.docker.password={docker_registry_account_password} \

--set nginx-ingress-controller.service.type=LoadBalancer \

--set core.ingress.enabled=true \

--set core.secretKey={dashboard_secret}

--set dashboard.ingress.enabled=true \

--namespace kintohub kintohub/kinto

Check the variables here.

Once the installation completed, you should run also the command below from the prompt.

Notes: if NetworkPolicies are enabled on your cluster, you need 'whitelist' the kintohub namespaces so that they can access your environments.

Run `kubectl get networkpolicies`. If it does not error, that means that NetworkPolicies are enabled.

If enabled, run `kubectl label ns kube-system argo cert-manager kintohub owner=kintohub --overwrite`.

> kubectl label ns kube-system argo cert-manager kintohub owner=kintohub --overwrite

This is because Digital Ocean by default enabled the network policy for your cluster. All of your services deployed will be unaccessible if you fail to run the line above.

Access KintoHub

Port forward kinto core and kinto dashboard

kubectl port-forward svc/kinto-core 8090 -n kintohub

kubectl port-forward svc/kinto-dashboard 5000 -n kintohub

Open localhost:5000.
