How to execute CF CLI commands in a Concourse task

Products

• VMware Tanzu Platform - Cloud Foundry

Issue/Introduction

Operator or developer requires executing Clound Foundry CLI commands from within a Concourse task & pipeline.

Guidelines for using CF CLI executable in Concourse & Platform Automation.

Resolution

There are multiple options for executing CF CLI commands in a Concourse task - 

• cf-cli-resource - This is a community supported resource that simplifies command execution and settings of authentication/org/space parameters. This resource is not supported by Broadcom and may be outdated.
  
  
• cloudfoundry/cli - This is the official open-source docker image for the Cloud Foundry CLI. Dockerhub contains the latest open-source version of CLI and continues to get updates.
  
  Below is an example pipeline utilizing CLI docker image -
  
  

  jobs:
  - name: deploy-app
    plan:
    - get: app-code
      trigger: true
    - task: push-to-cf
      config:
        platform: linux
        image_resource:
          type: registry-image
          source:
            repository: cloudfoundry/cli
            tag: latest
        inputs:
          - name: app-code
        run:
          path: /bin/sh
          args:
            - -c
            - |
              cf api ((cf-api-url)) --skip-cert-check
              cf auth ((cf-username)) ((cf-password))
              cf target -o ((cf-org)) -s ((cf-space))
              cd app-code
              cf push APP-NAME

 

• Build your own docker image - Create a custom image to use as a resource (as in pipeline example above) containing all the utilities that you need.
  
  Example dockerfile that pulls in CF CLI & OM:
  

  FROM ubuntu:jammy 
  
  RUN apt-get update -y
  RUN apt-get install jq curl wget openssh-client zip git -y
  
  # om cli
  
  RUN curl -L -O https://github.com/pivotal-cf/om/releases/download/7.12.0/om-linux-amd64-7.12.0 -k
  RUN mv om-linux-amd64-7.12.0 /usr/local/bin/om
  RUN chmod +x /usr/local/bin/om
  
  # cf cli 
  
  RUN wget -O cf.tgz "https://packages.cloudfoundry.org/stable?release=linux64-binary&version=8.7.10&source=github-rel" --no-check-certificate
  RUN tar -xzvf cf.tgz
  RUN mv cf8 /usr/local/bin/cf
  RUN chmod +x /usr/local/bin/cf
