Deploy Hydrolix

In this step of the deployment process, you'll use hkt to create the operator.yaml and hydrolixcluster.yaml configuration files. Then, you'll use those files to deploy Hydrolix on your Kubernetes cluster.

Prerequisite: Environment Variables

These CLI commands require you to set environment variables before generating the configuration. See Prepare your GKE Cluster for more information about the required inputs.

Configure and Deploy the Hydrolix Operator

πŸ“˜

Repeat this Step to Upgrade Hydrolix

To upgrade a Hydrolix deployment, download a newer version of hkt and repeat this step.

The operator-resources command generates the Kubernetes resource definitions required for deploying the operator, service accounts, and role permissions. The operator manages all Hydrolix cluster deployments. Run the following command to generate a YAML operator configuration file for your cluster:

curl "https://www.hydrolix.io/operator/latest/operator-resources?namespace=${HDX_KUBERNETES_NAMESPACE}&gcp-storage-sa=${GCP_STORAGE_SA}" > operator.yaml

Next, use the Kubernetes command line tool (kubectl) to apply the generated configuration to your Kubernetes cluster:

kubectl apply -f operator.yaml

Configure and Deploy a Hydrolix Cluster

The hydrolix-cluster command generates the hydrolixcluster.yaml deployment file. We provide scale profiles for various cloud providers and deployment sizes. You can optionally specify a profile using the scale-profile flag. By default, Hydrolix uses a minimal profile. Add the following to a file named hydrolixcluster.yaml to generate a YAML cluster configuration file for a dev scale deployment:

apiVersion: hydrolix.io/v1
kind: HydrolixCluster
metadata:
  name: hdx
  namespace: ${HDX_KUBERNETES_NAMESPACE}
spec:
  admin_email: ${HDX_ADMIN_EMAIL}
  db_bucket_region: ${HDX_BUCKET_REGION}
  db_bucket_url: ${HDX_DB_BUCKET_URL}
  env: {}
  hydrolix_name: hdx
  hydrolix_url: ${HDX_HYDROLIX_URL}
  ip_allowlist:
  - 42.78.92.98/32 // TODO: Replace this with your IP address!
  kubernetes_namespace: ${HDX_KUBERNETES_NAMESPACE}
  overcommit: false
  scale: {}
  scale_profile: dev

Use the following command to replace the environment variables above with their values:

eval "echo \"$(cat hydrolixcluster.yaml)\""

Don't forget to add your IP address to the allowlist. You can get your IP address by running curl -s ifconfig.me.

Manually Edit Configuration Files

You can also edit the hydrolixcluster.yaml to tune each deployment to your resource requirements.

Next, use the Kubernetes command line tool (kubectl) to apply the generated configuration to your Kubernetes cluster:

kubectl apply -f hydrolixcluster.yaml

Create Your DNS Record

Next, create a DNS record so you can access your cluster. Run the following command to retrieve the traefik record:

kubectl get service/traefik --namespace=$HDX_KUBERNETES_NAMESPACE

You should see output similar to the following:

NAME          TYPE           CLUSTER-IP       EXTERNAL-IP                                                                     PORT(S)                                AGE                                                                          8089/TCP                               68m
traefik       LoadBalancer   10.64.14.42    34.66.136.134   80:31708/TCP,9000:32344/TCP            2m50s

Check Deployment Status

You can now check the status of your deployment. Run the followingkubectl command to see the status of all pods in your cluster:

kubectl get pods --namespace $HDX_KUBERNETES_NAMESPACE

You should see output similar to the following:
