This is a step-by-step guide to install an Aptos node on Google GCP. Follow these steps to configure a validator node and a validator fullnode on separate machines.

Did you set up your GCP account and created a project?

This guide assumes you already have GCP account setup, and have created a new project for deploying Aptos node. If you are not familiar with GCP (Google Cloud Platform), checkout this Prerequisites section for GCP account setup.

Before you proceed

Make sure the following are installed on your local computer:


One validator node + one validator fullnode

Follow the below instructions twice, i.e., first on one machine to run a validator node and the second time on another machine to run a validator fullnode.

  1. Create a working directory for your configuration.

    • Choose a workspace name, for example, mainnet for mainnet, or testnet for testnet, and so on. Note: This defines the Terraform workspace name, which, in turn, is used to form the resource names.

      export WORKSPACE=mainnet
    • Create a directory for the workspace

      mkdir -p ~/$WORKSPACE
    • Choose a username for your node, for example alice.

      export USERNAME=alice
  2. Create a storage bucket for storing the Terraform state on Google Cloud Storage. Use the GCP UI or Google Cloud Storage command to create the bucket. The name of the bucket must be unique. See the Google Cloud Storage documentation here:

    gsutil mb gs://BUCKET_NAME
    # for example
    gsutil mb gs://<project-name>-aptos-terraform-dev
  3. Create Terraform file called in your working directory:

    cd ~/$WORKSPACE
  4. Modify file to configure Terraform, and create fullnode from Terraform module. Example content for

    terraform {
    required_version = "~> 1.2.0"
    backend "gcs" {
    bucket = "BUCKET_NAME" # bucket name created in step 2
    prefix = "state/aptos-node"

    module "aptos-node" {
    # download Terraform module from aptos-labs/aptos-core repo
    source = ""
    region = "us-central1" # Specify the region
    zone = "c" # Specify the zone suffix
    project = "<GCP Project ID>" # Specify your GCP project ID
    era = 1 # bump era number to wipe the chain
    chain_id = 1 # for mainnet. Use different value for testnet or devnet.
    image_tag = "mainnet" # Specify the docker image tag to use
    validator_name = "<Name of your validator, no space, e.g. aptosbot>"

    For the full customization options, see the variables file here, and the helm values.

  5. Initialize Terraform in the same directory of your file

    terraform init

    This will download all the Terraform dependencies for you, in the .terraform folder in your current working directory.

  6. Create a new Terraform workspace to isolate your environments:

    terraform workspace new $WORKSPACE
    # This command will list all workspaces
    terraform workspace list
  7. Apply the configuration.

    terraform apply

    This might take a while to finish (10 - 20 minutes), Terraform will create all the resources on your cloud account.

  8. Once Terraform apply finishes, you can check if those resources are created:

    • gcloud container clusters get-credentials aptos-$WORKSPACE --zone <region/zone> --project <project> to configure the access for k8s cluster.
    • kubectl get pods this should have haproxy, validator and fullnode. with validator and fullnode pod pending (require further action in later steps)
    • kubectl get svc this should have validator-lb and fullnode-lb, with an external-IP you can share later for connectivity.
  9. Get your node IP info:

    export VALIDATOR_ADDRESS="$(kubectl get svc ${WORKSPACE}-aptos-node-0-validator-lb --output jsonpath='{.status.loadBalancer.ingress[0].ip}')"

    export FULLNODE_ADDRESS="$(kubectl get svc ${WORKSPACE}-aptos-node-0-fullnode-lb --output jsonpath='{.status.loadBalancer.ingress[0].ip}')"
  10. Generate the key pairs (node owner, voter, operator key, consensus key and networking key) in your working directory.

    aptos genesis generate-keys --output-dir ~/$WORKSPACE/keys

    This will create 4 key files under ~/$WORKSPACE/keys directory:

    • public-keys.yaml

    • private-keys.yaml

    • validator-identity.yaml, and

    • validator-full-node-identity.yaml.


      Backup your private-keys.yaml somewhere safe. These keys are important for you to establish ownership of your node. Never share private keys with anyone.

  11. Configure the validator information.

    aptos genesis set-validator-configuration \
    --local-repository-dir ~/$WORKSPACE \
    --username $USERNAME \
    --owner-public-identity-file ~/$WORKSPACE/keys/public-keys.yaml \
    --validator-host $VALIDATOR_ADDRESS:6180 \
    --full-node-host $FULLNODE_ADDRESS:6182 \
    --stake-amount 100000000000000

    This will create two YAML files in the ~/$WORKSPACE/$USERNAME directory: owner.yaml and operator.yaml.

  12. Download the following files by following the download commands on the Node Files page:

    • genesis.blob
    • waypoint.txt
  13. To summarize, in your working directory you should have a list of files:

    • The Terraform files to install the aptos-node module (from steps 3 and 4).
    • keys folder, which includes:
      • public-keys.yaml: Public keys for the owner account, consensus, networking (from step 10).
      • private-keys.yaml: Private keys for the owner account, consensus, networking (from step 10).
      • validator-identity.yaml: Private keys for setting the Validator identity (from step 10).
      • validator-full-node-identity.yaml: Private keys for setting validator full node identity (from step 10).
    • username folder, which includes:
      • owner.yaml: define owner, operator, and voter mapping. They are all the same account in test mode (from step 11).
      • operator.yaml: Node information that will be used for both the Validator and the fullnode (from step 11).
    • waypoint.txt: The waypoint for the genesis transaction (from step 12).
    • genesis.blob The genesis binary that contains all the information about the framework, validatorSet and more (from step 12).
  14. Insert genesis.blob, waypoint.txt and the identity files as secret into k8s cluster.

    kubectl create secret generic ${WORKSPACE}-aptos-node-0-genesis-e1 \
    --from-file=genesis.blob=genesis.blob \
    --from-file=waypoint.txt=waypoint.txt \
    --from-file=validator-identity.yaml=keys/validator-identity.yaml \

    The -e1 suffix refers to the era number. If you changed the era number, make sure it matches when creating the secret.

  15. Check that all pods are running.

    kubectl get pods

    node1-aptos-node-0-fullnode-e9-0 1/1 Running 0 4h31m
    node1-aptos-node-0-haproxy-7cc4c5f74c-l4l6n 1/1 Running 0 4h40m
    node1-aptos-node-0-validator-0 1/1 Running 0 4h30m

Now you have successfully completed setting up your node. Make sure that you have set up one machine to run a validator node and a second machine to run a validator fullnode.
