Union Helm Charts

Dataplane

Assumptions

• You have a Union organization that has already been created and you know the URL of your control plane host.
• The Union provided client ID and secret.
• You have a Kubernetes cluster, running one of the most recent three minor K8s versions. Learn more
• Object storage provided by a vendor or an S3 compatible platform (such as Minio.

Some sample Terraform configurations are available in the providers directory.

Prerequisites

• Install Helm 3
• Install union and uctl.

Deploy the Union operator

1. Add the Union.ai Helm repo:

helm repo add unionai https://unionai.github.io/helm-charts/
helm repo update

2. Create a values file that include, at a minimum, the following fields:

host: <YOUR_UNION_CONTROL_PLANE_URL>
clusterName: <MY_CLUSTER> #arbitrary and unique cluster identifier
orgName: <MY_ORG> #Name of your Union.ai organization
provider: aws #The cloud provider your cluster is running in.  Acceptable values include `aws`, `gcp`, `azure`, `oci`, and `metal` (for self-managed or on-prem clusters).
storage:
  endpoint: <STORAGE_ENDPOINT> #This is the S3 API endpoint provided by your cloud vendor.
  accessKey: <S3_ACCESS_KEY>
  secretKey: <S3_SECRET_KEY>
  bucketName: <S3_BUCKET_NAME>
  fastRegistrationBucketName: <S3_BUCKET_NAME> #it can be the same as bucketName
  region: <CLOUD_REGION> # not needed for on-prem deployments
secrets:
  admin:
    create: true
    # Insert values from step 4
    clientSecret: <UNION_CLIENT_SECRET> #you can also provide this as a command-line argument
    clientId: "<UNION_CLIENT_ID>"

3. Optionally configure the resource limits and requests for the different services. By default these will be set minimally, will vary depending on usage, and follow the Kubernetes ResourceRequirements specification.

   • clusterresourcesync.resources
   • flytepropeller.resources
   • flytepropellerwebhook.resources
   • operator.resources
   • proxy.resources

4. Install the Union operator and CRDs:

helm upgrade --install unionai-dataplane-crds unionai/dataplane-crds
helm upgrade --install unionai-dataplane unionai/dataplane \
    --create-namespace \
    --namespace union \
    --values <YOUR_VALUES_FILE>

5. Once deployed you can check to see if the cluster has been successfully registered to the control plane:

uctl get cluster
 ----------- ------- --------------- -----------
| NAME      | ORG   | STATE         | HEALTH    |
 ----------- ------- --------------- -----------
| <cluster> | <org> | STATE_ENABLED | HEALTHY   |
 ----------- ------- --------------- -----------
