AWS EKS Setup

1. Generate Access keys for CLI, SDK, & API access

   • Create Access Key
     • aws configure
       • Set AWS Access Key ID
       • Set AWS Secret Access Key
       • Set Default region name

2. Install eksctl

3. Setup Environment Variables

   CHART_VERSION=0.2.4+3003
   BUILD_CHART_VERSION=0.1.0+7
   CLUSTER_NAME=pyrsia-staging
   EXTERNALDNS_NAMESPACE=external-dns
   PYRSIA_NAMESPACE=pyrsia-node
   PYRSIA_BASE_DOMAIN=pyrsia-aws.link
   PYRSIA_DOMAIN=staging.${PYRSIA_BASE_DOMAIN}
   PYRSIA_BOOTDNS=boot.${PYRSIA_DOMAIN}
   PYRSIA_NODE_ZERO=pyrsia-node-0.${PYRSIA_DOMAIN}

4. Create the Cluster

   cat <<EOF | eksctl create cluster -f -
   ---
   apiVersion: eksctl.io/v1alpha5
   kind: ClusterConfig
   metadata:
     name: ${CLUSTER_NAME}
     region: us-east-1
   cloudWatch:
     clusterLogging:
       enableTypes:
         - audit
         - authenticator
   managedNodeGroups:
     - name: ng-1
       amiFamily: AmazonLinux2
       instanceSelector:
         cpuArchitecture: x86_64
         memory: 2GiB
         vCPUs: 2
       instanceTypes:
         - t3.small
         - t3a.small
   iam:
     withOIDC: true
   addons:
     - name: aws-ebs-csi-driver
       version: v1.13.0-eksbuild.3
       attachPolicyARNs:
         - arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy
   EOF

5. Create Kubernetes Namespaces

   • kubectl create namespace ${PYRSIA_NAMESPACE}
   • kubectl create namespace ${EXTERNALDNS_NAMESPACE}

6. Create Route 53 Policy

   • See route53-policy.json
   • aws iam create-policy --policy-name "AllowExternalDNSUpdates" --policy-document file://route53-policy.json

7. Attach Route 53 Policy

   • aws iam attach-role-policy --role-name $(aws eks describe-nodegroup --cluster-name ${CLUSTER_NAME} --nodegroup-name ng-1 --query nodegroup.nodeRole --out text | awk -F/ '{print $2}') --policy-arn $(aws iam list-policies --query 'Policies[?PolicyName==AllowExternalDNSUpdates].Arn' --output text)

8. Setup Route 53 Domain

   • aws route53 create-hosted-zone --name "${PYRSIA_BASE_DOMAIN}." --caller-reference "external-dns-$(date +%s)"

9. Get DNS Server List

   • aws route53 list-resource-record-sets --output text --hosted-zone-id $(aws route53 list-hosted-zones-by-name --output json --dns-name "${PYRSIA_BASE_DOMAIN}." | jq -r ".HostedZones[0].Id") --query "ResourceRecordSets[?Type == 'NS'].ResourceRecords[*].Value | []" | tr '\t' '\n'

10. Generate Pyrsia Keys using openssl v3

    openssl genpkey -algorithm Ed25519 -out ed25519.pem
    openssl pkey -in ed25519.pem -pubout -outform DER | tail -c +13 > id_ed25519.pub
    openssl pkey -in ed25519.pem -out - -outform DER | tail -c +17 > id_ed25519.pri
    cat id_ed25519.pri id_ed25519.pub > ed25519.ser

11. Create DNS Alias

    
    aws route53 change-resource-record-sets \
    --hosted-zone-id $(aws route53 list-hosted-zones-by-name --output json --dns-name "${PYRSIA_BASE_DOMAIN}." | jq -r ".HostedZones[0].Id" | cut -d/ -f3) \
    --change-batch '
    {
       "Comment": "Creating Alias resource for '${PYRSIA_BOOTDNS}'",
       "Changes": [
          {
             "Action": "CREATE",
             "ResourceRecordSet": {
             "Name": "'${PYRSIA_BOOTDNS}'",
             "Type": "A",
             "AliasTarget": {
                "DNSName": "'${PYRSIA_NODE_ZERO}'",
                "EvaluateTargetHealth": false,
                "HostedZoneId": "'$(aws route53 list-hosted-zones-by-name --output json --dns-name "${PYRSIA_BASE_DOMAIN}}." | jq -r ".HostedZones[0].Id" | cut -d/ -f3 )'"
             }
             }
          }
       ]
    }'

12. Deploy Pyrsia via Helm

    • helm repo update pyrsia-nightly
    • helm upgrade node1 --install -n pyrsia-node pyrsia-staging/pyrsia-node --set "domain=${PYRSIA_DOMAIN}" --set bootdns=${PYRSIA_BOOTDNS} --set keys.p2p=$(cat ed25519.ser | base64) --set keys.blockchain=$(cat ed25519.ser | base64) --version "${CHART_VERSION}"

13. Deploy Build Service via Helm (Optional)

    • helm upgrade build1 --install -n pyrsia-node pyrsia-nightly/pyrsia-build-service --set bootdns=${PYRSIA_BOOTDNS} --version "${BUILD_ChART_VERSION}"
