Okteto Registry with Amazon S3 Bucket

This guide will walk you through the process of setting up the Okteto Registry with S3 storage to store your container images.

Requirements​

Before you start, make sure you have the following CLI installed in your machine:

Setting up environment variables​

We recommend configuring the following environment variables to help you scripting the Okteto Registry configuration:

Your Kubernetes cluster name:

export CLUSTER_NAME="okteto"

Your bucket name:

export BUCKET_NAME="${CLUSTER_NAME}-registry-bucket"
tip

S3 bucket names must be globally unique. Ensure you select a unique name for your bucket. You may include a random string in the bucket name to guarantee its uniqueness.

Your AWS Account ID:

export AWS_ACCOUNT_ID="$(aws sts get-caller-identity --query "Account" --output text)"

Your AWS Region:

export AWS_REGION="$(aws configure get region)"

Disable AWS CLI pagination (optional):

export AWS_PAGER=""

Create S3 Bucket​

Create your S3 bucket with the following command:

aws s3api create-bucket \
  --bucket="${BUCKET_NAME}" \
  --region="${AWS_REGION}" \
  --create-bucket-configuration=LocationConstraint="${AWS_REGION}"

Create IAM Role​

Save the following IAM Policy definition to a file and update the Resource field to match your S3 bucket name:

okteto-registry-iam-policy.json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListBucket",
        "s3:GetBucketLocation",
        "s3:ListBucketMultipartUploads"
      ],
      "Resource": "arn:aws:s3:::REPLACE-ME-WITH-YOUR-BUCKET-NAME"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:PutObject",
        "s3:GetObject",
        "s3:DeleteObject",
        "s3:ListMultipartUploadParts",
        "s3:AbortMultipartUpload"
      ],
      "Resource": "arn:aws:s3:::REPLACE-ME-WITH-YOUR-BUCKET-NAME/*"
    }
  ]
}
note

The IAM policy is maintained by the distribution/distribution project. You can find the latest version of the policy here.

Create the IAM Policy with the following command:

aws iam create-policy \
  --policy-name="${CLUSTER_NAME}-okteto-registry-policy" \
  --policy-document="file://okteto-registry-iam-policy.json"

Configure your Kubernetes context to the cluster where Okteto is installed and get the Okteto Registry service account name with the following command:

export OKTETO_REGISTRY_SERVICE_ACCOUNT_NAME="$(kubectl get sa -n=okteto -l=app.kubernetes.io/component=registry -o=jsonpath='{.items[0].metadata.name}')"

Create the IAM Role with the following command:

eksctl create iamserviceaccount \
  --region="${AWS_REGION}" \
  --name="${OKTETO_REGISTRY_SERVICE_ACCOUNT_NAME}" \
  --namespace="okteto" \
  --cluster="${CLUSTER_NAME}" \
  --role-name="${CLUSTER_NAME}-okteto-registry-role" \
  --role-only \
  --attach-policy-arn="arn:aws:iam::${AWS_ACCOUNT_ID}:policy/${CLUSTER_NAME}-okteto-registry-policy" \
  --approve

Configure Okteto to use your IAM Role​

Set the IAM Role ARN with the following command:

export ROLE_ARN="arn:aws:iam::${AWS_ACCOUNT_ID}:role/${CLUSTER_NAME}-okteto-registry-role"

Apply the following snippet to your Okteto Helm configuration file and replace the highlighted values:

config.yaml
registry:
  storage:
    provider:
      aws:
        enabled: true
        bucket: "REPLACE ME WITH YOUR BUCKET NAME"
        region: "REPLACE ME WITH YOUR AWS REGION"
        iam:
          enabled: false
  serviceAccount:
    annotations:
      eks.amazonaws.com/role-arn: "REPLACE_ME_WITH_YOUR_ROLE_ARN"

Finally, upgrade your Okteto instance for the new configuration to be applied. We recommend that you upgrade to the same version that you already have to minimize the changes and help you troubleshoot any issues.
