Installing on Google Cloud VM

Prerequisites

Having piped’s ID and Key strings

• Ensure that the piped has been registered and you are having its PIPED_ID and PIPED_KEY strings.
• If you are not having them, this page guides you how to register a new one.

Preparing SSH key

• If your Git repositories are private, piped requires a private SSH key to access those repositories.
• Please checkout this documentation for how to generate a new SSH key pair. Then add the public key to your repositories. (If you are using GitHub, you can add it to Deploy Keys at the repository’s Settings page.)

Installation

• Preparing a piped configuration file as the following:

  apiVersion: pipecd.dev/v1beta1
  kind: Piped
  spec:
    projectID: {PROJECT_ID}
    pipedID: {PIPED_ID}
    pipedKeyData: {BASE64_ENCODED_PIPED_KEY}
    # Write in a format like "host:443" because the communication is done via gRPC.
    apiAddress: {CONTROL_PLANE_API_ADDRESS}
  
    git:
      sshKeyData: {BASE64_ENCODED_PRIVATE_SSH_KEY}
  
    repositories:
      - repoId: {REPO_ID_OR_NAME}
        remote: git@github.com:{GIT_ORG}/{GIT_REPO}.git
        branch: {GIT_BRANCH}
  
    # Optional
    # Uncomment this if you want to enable this Piped to handle Cloud Run application.
    # platformProviders:
    #  - name: cloudrun-in-project
    #    type: CLOUDRUN
    #    config:
    #      project: {GCP_PROJECT_ID}
    #      region: {GCP_PROJECT_REGION}
  
    # Optional
    # Uncomment this if you want to enable this Piped to handle Terraform application.
    #  - name: terraform-gcp
    #    type: TERRAFORM
  
    # Optional
    # Uncomment this if you want to enable SecretManagement feature.
    # https://pipecd.dev//docs/user-guide/managing-application/secret-management/
    # secretManagement:
    #   type: KEY_PAIR
    #   config:
    #     privateKeyData: {BASE64_ENCODED_PRIVATE_KEY}
    #     publicKeyData: {BASE64_ENCODED_PUBLIC_KEY}
  

See ConfigurationReference for the full configuration.

• Creating a new secret in SecretManager to store above configuration data securely

  gcloud secrets create vm-piped-config --data-file={PATH_TO_CONFIG_FILE}
  

• Creating a new Service Account for Piped and giving it needed roles

  gcloud iam service-accounts create vm-piped \
    --description="Using by Piped running on Google Cloud VM" \
    --display-name="vm-piped"
  
  # Allow Piped to access the created secret.
  gcloud secrets add-iam-policy-binding vm-piped-config \
    --member="serviceAccount:vm-piped@{GCP_PROJECT_ID}.iam.gserviceaccount.com" \
    --role="roles/secretmanager.secretAccessor"
  
  # Allow Piped to write its log messages to Google Cloud Logging service.
  gcloud projects add-iam-policy-binding {GCP_PROJECT_ID} \
    --member="serviceAccount:vm-piped@{GCP_PROJECT_ID}.iam.gserviceaccount.com" \
    --role="roles/logging.logWriter"
  
  # Optional
  # If you want to use this Piped to handle Cloud Run application
  # run the following command to give it the needed roles.
  # https://cloud.google.com/run/docs/reference/iam/roles#additional-configuration
  #
  # gcloud projects add-iam-policy-binding {GCP_PROJECT_ID} \
  #   --member="serviceAccount:vm-piped@{GCP_PROJECT_ID}.iam.gserviceaccount.com" \
  #   --role="roles/run.developer"
  #
  # gcloud iam service-accounts add-iam-policy-binding {GCP_PROJECT_NUMBER}-compute@developer.gserviceaccount.com \
  #   --member="serviceAccount:vm-piped@{GCP_PROJECT_ID}.iam.gserviceaccount.com" \
  #   --role="roles/iam.serviceAccountUser"
  

• Running Piped on a Google Cloud VM

  • Piped with Remote-upgrade
  • Piped

  # Enable remote-upgrade feature of Piped.
  # https://pipecd.dev/docs/user-guide/managing-piped/remote-upgrade-remote-config/#remote-upgrade
  # This allows upgrading Piped to a new version from the web console.
  
    gcloud compute instances create-with-container vm-piped \
      --container-image="ghcr.io/pipe-cd/launcher:v0.49.4" \
      --container-arg="launcher" \
      --container-arg="--config-from-gcp-secret=true" \
      --container-arg="--gcp-secret-id=projects/{GCP_PROJECT_ID}/secrets/vm-piped-config/versions/{SECRET_VERSION}" \
      --network="{VPC_NETWORK}" \
      --subnet="{VPC_SUBNET}" \
      --scopes="cloud-platform" \
      --service-account="vm-piped@{GCP_PROJECT_ID}.iam.gserviceaccount.com"
    
  

  # This just installs a Piped with the specified version.
  # Whenever you want to upgrade that Piped to a new version or update its config data you have to restart it.
  
    gcloud compute instances create-with-container vm-piped \
      --container-image="ghcr.io/pipe-cd/piped:v0.49.4" \
      --container-arg="piped" \
      --container-arg="--config-gcp-secret=projects/{GCP_PROJECT_ID}/secrets/vm-piped-config/versions/{SECRET_VERSION}" \
      --network="{VPC_NETWORK}" \
      --subnet="{VPC_SUBNET}" \
      --scopes="cloud-platform" \
      --service-account="vm-piped@{GCP_PROJECT_ID}.iam.gserviceaccount.com"
    
  

After that, you can see on PipeCD web at Settings page that Piped is connecting to the Control Plane. You can also view Piped log as described here.
