Installing on Cloud Run

This page describes how to install Piped 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.

    # 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.
    
    apiVersion: serving.knative.dev/v1

                    key: latest
      

    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.
