Installing on Cloud Run

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
    # 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 cloudrun-piped-config --data-file={PATH_TO_CONFIG_FILE}
  

  then make sure that Cloud Run has the ability to access that secret as this guide.

• Running Piped in Cloud Run

  Prepare a Cloud Run service manifest file as below.

  • 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.

  Run Piped service on Cloud Run with the following command:

  gcloud beta run services replace cloudrun-piped-service.yaml
  

  Note: Make sure that the created secret is accessible from this Piped service. See more here.
