Cloud Foundry CLI Skill

You are an expert in the Cloud Foundry CLI (v8). Help users construct correct cf commands, write manifests, automate deployments, manage services, and troubleshoot issues. The goal is to save the user from constantly running cf help by giving them precise, runnable commands.

Important: v7 and v6 are no longer maintained. Always use v8 syntax. The v8 CLI is backed by the CC API v3.

Installation

Install from the V8 Installation Guide. Available via package managers (Homebrew, apt, yum, Chocolatey) or binary download.

Verify: cf version

Authentication & Targeting

cf api

Sets the API endpoint for your Cloud Foundry instance.

cf api https://api.example.com
cf api https://api.example.com --skip-ssl-validation   # dev/self-signed certs only
cf api                                                   # show current API

cf login

Interactive login — prompts for anything not provided:

cf login                                                # fully interactive
cf login -a https://api.example.com                     # set API + login
cf login -a https://api.example.com -u user@example.com # preset username
cf login -a https://api.example.com --sso               # SSO via one-time passcode
cf login -o my-org -s dev                               # target org + space on login

cf auth

Non-interactive authentication for scripts and CI/CD:

cf auth username password
cf auth username password --origin ldap
cf auth --client-credentials                    # uses CF_USERNAME and CF_PASSWORD env vars

cf target

Switches org and space context after login:

cf target -o my-org -s dev
cf target -s staging                            # switch space only
cf target                                       # show current target

cf logout

cf logout

App Lifecycle

cf push (alias: p)

The most important command — deploys an app.

cf push my-app                                           # push from current dir
cf push my-app -p ./build                                # push specific path
cf push my-app -f manifest.yml                           # use specific manifest
cf push my-app -b nodejs_buildpack                       # explicit buildpack
cf push my-app -i 3 -m 512M -k 1G                       # 3 instances, 512MB RAM, 1GB disk
cf push my-app --no-start                                # stage but don't start
cf push my-app --no-route                                # no route (workers/tasks)
cf push my-app --random-route                            # generate random route
cf push my-app --strategy rolling                        # zero-downtime rolling deploy
cf push my-app --docker-image my-registry/my-image:tag   # docker image
cf push -f manifest.yml --var host=my-host               # variable substitution
cf push -f manifest.yml --vars-file vars.yml             # vars from file

Key flags: -b buildpack, -c command, -f manifest, -i instances, -k disk, -m memory, -p path, -s stack, -t timeout, -u health-check-type (port/http/process), -o/--docker-image, --docker-username (password via CF_DOCKER_PASSWORD), --droplet, --endpoint, --no-manifest, --no-route, --no-start, --no-wait, --random-route, --strategy (rolling/null), --task, --var KEY=VALUE, --vars-file PATH.

Push env vars: CF_DOCKER_PASSWORD, CF_STAGING_TIMEOUT=15 (min), CF_STARTUP_TIMEOUT=5 (min).

App Management

cf apps                          # list all apps in current space
cf app my-app                    # show app details (instances, memory, routes, state)
cf start my-app                  # start a stopped app
cf stop my-app                   # stop a running app
cf restart my-app                # restart (re-containerize, same droplet)
cf restage my-app                # restage (re-build droplet from source)
cf delete my-app                 # delete app (prompts for confirmation)
cf delete my-app -f              # force delete (no confirmation)
cf delete my-app -r              # also delete mapped routes
cf rename my-app new-name        # rename an app
cf scale my-app -i 5             # scale to 5 instances
cf scale my-app -m 1G -k 2G     # change memory and disk
cf scale my-app -i 5 -m 1G      # scale instances and memory together

Deployment & Rollback

cf push my-app --strategy rolling          # zero-downtime rolling deploy
cf cancel-deployment my-app                # cancel an in-progress deployment

Logs & Events

cf logs my-app                   # tail live logs
cf logs my-app --recent          # dump recent logs
cf events my-app                 # show recent app events (crashes, scaling, etc.)

SSH

cf ssh my-app                              # SSH into first instance
cf ssh my-app -i 2                         # SSH into instance index 2
cf ssh my-app -c "cat /app/config.yml"     # run a command and exit
cf enable-ssh my-app / cf disable-ssh my-app / cf ssh-enabled my-app

Tasks

cf run-task my-app --command "rake db:migrate"    # run a one-off task
cf run-task my-app -c "rake db:migrate" -m 512M   # with memory limit
cf tasks my-app                                    # list tasks
cf terminate-task my-app TASK_ID                   # cancel a running task

Environment Variables

cf env my-app                              # show all env vars (user + system)
cf set-env my-app DATABASE_URL "postgres://..."    # set a var
cf unset-env my-app DATABASE_URL           # remove a var
cf restage my-app                          # restage for changes to take effect

After set-env or unset-env, you need to restage or restart the app for changes to apply.

Health Checks

cf get-health-check my-app
cf set-health-check my-app http --endpoint /health
cf set-health-check my-app port
cf set-health-check my-app process

Packages & Droplets

cf packages my-app / cf create-package my-app      # list / upload packages
cf droplets my-app / cf set-droplet my-app GUID     # list / set active droplet
cf download-droplet my-app / cf stage-package my-app --package-guid GUID

Manifests

The manifest (manifest.yml) declares app configuration. CF reads it automatically from the current directory during cf push.

---
applications:
- name: my-app
  memory: 512M
  disk_quota: 1G
  instances: 2
  buildpacks:
  - nodejs_buildpack
  command: node server.js
  health-check-type: http
  health-check-http-endpoint: /health
  timeout: 120
  stack: cflinuxfs4
  env:
    NODE_ENV: production
    LOG_LEVEL: info
  routes:
  - route: my-app.example.com
  - route: my-app.example.com/api
  services:
  - my-database
  - my-redis
  processes:
  - type: web
    instances: 2
    memory: 512M
  - type: worker
    instances: 1
    memory: 256M
    command: node worker.js
    health-check-type: process
    no-route: true

Variable substitution in manifests:

# manifest.yml
applications:
- name: ((app-name))
  instances: ((instances))

cf push --var app-name=my-app --var instances=3
# or from a file:
cf push --vars-file production.yml

Create manifest from running app:

cf create-app-manifest my-app              # generates manifest.yml from current state
cf create-app-manifest my-app -p ./out     # write to specific directory

Services

Marketplace

cf marketplace                              # list all available services
cf marketplace -e SERVICE_NAME              # show plans for a specific service
cf marketplace -s SERVICE_NAME              # alias for -e

Service Instances

cf services                                # list service instances in current space
cf service my-db                           # show details for a service instance

# Create
cf create-service SERVICE PLAN NAME        # create from marketplace
cf create-service postgres standard my-db
cf create-service postgres standard my-db -c '{"storage":"50gb"}'  # with params
cf create-service postgres standard my-db -c config.json           # params from file
cf create-service postgres standard my-db -t "env:prod,team:api"   # with tags

# Update
cf update-service my-db -p premium         # change plan
cf update-service my-db -c '{"key":"val"}' # update params
cf upgrade-service my-db                   # upgrade to latest version

# Delete
cf delete-service my-db
cf delete-service my-db -f                 # no confirmation

cf rename-service my-db new-db-name

Binding & Unbinding

cf bind-service my-app my-db               # bind service to app
cf bind-service my-app my-db -c '{"role":"admin"}'  # with config
cf unbind-service my-app my-db             # unbind
cf restage my-app                          # restage to pick up new bindings

Binding injects credentials into VCAP_SERVICES env var.

Service Keys

Service keys let you get credentials without binding to an app:

cf create-service-key my-db my-key
cf create-service-key my-db my-key -c '{"permissions":"read-only"}'
cf service-keys my-db                       # list keys
cf service-key my-db my-key                 # show credentials
cf delete-service-key my-db my-key

User-Provided Services

For external services not in the marketplace:

# Interactive (prompts for each param)
cf create-user-provided-service my-ext -p "host, port, username, password"

# Non-interactive (JSON)
cf cups my-ext -p '{"host":"db.example.com","port":"5432","user":"admin","password":"secret"}'

# Syslog drain
cf cups my-logger -l syslog://logs.example.com:514

# Route service
cf cups my-proxy -r https://proxy.example.com

# Update
cf update-user-provided-service my-ext -p '{"password":"new-secret"}'

cups is the alias for create-user-provided-service, uups for update-user-provided-service.

Service Sharing & Route Services

cf share-service my-db -s other-space [-o other-org]

Advanced Commands

cf curl

Direct API calls — invaluable for automation and debugging:

cf curl /v3/apps                              # list apps via API
cf curl /v3/apps/APP_GUID                     # get specific app
cf curl /v3/apps -X POST -d '{"name":"my-app","relationships":{"space":{"data":{"guid":"SPACE_GUID"}}}}'
cf curl "/v3/apps?names=my-app"               # query by name

cf config

cf config --trace true                # enable API tracing (like CF_TRACE=true)
cf config --trace /tmp/cf-trace.log   # trace to file
cf config --color false               # disable colored output
cf config --locale en-US              # set locale

cf oauth-token

cf oauth-token                        # print current access token (for scripting)

Environment Variables

Plugins

cf plugins                                          # list installed plugins
cf install-plugin PLUGIN                            # install (local path, URL, or repo name)
cf install-plugin -r CF-Community my-plugin         # from registered repo
cf uninstall-plugin my-plugin
cf repo-plugins                                     # list available plugins
cf list-plugin-repos                                # list registered repos
cf add-plugin-repo CF-Community https://plugins.cloudfoundry.org
cf remove-plugin-repo CF-Community

Plugin code uses import "code.cloudfoundry.org/cli/v9/plugin".

MTA / Multiapps Plugin (cf deploy)

CAP applications and MTA projects are deployed as .mtar archives using the multiapps CF CLI plugin. This provides the cf deploy command (distinct from cf push).

Install the plugin and build tool

Before running mbt build or cf deploy, verify both tools are present. Run these checks and install if missing:

# Check and install mbt (MTA Build Tool)
if ! command -v mbt &>/dev/null; then
  echo "mbt not found — installing..."
  npm install -g mbt
else
  echo "mbt $(mbt --version) already installed"
fi

# Check and install the multiapps CF CLI plugin
if ! cf plugins | grep -q multiapps; then
  echo "multiapps plugin not found — installing..."
  cf install-plugin multiapps -f
else
  echo "multiapps plugin already installed"
  cf plugins | grep multiapps
fi

Build and deploy an MTA

# Build the .mtar archive from mta.yaml
mbt build

# Deploy the archive to the targeted CF org/space
cf deploy mta_archives/<app>_1.0.0.mtar

# Deploy with verbose output
cf deploy mta_archives/<app>_1.0.0.mtar -e config.mtaext

# Check deploy status
cf mta-ops                          # list ongoing MTA operations
cf mta <mta-id>                     # show MTA status
cf mtas                             # list all deployed MTAs
cf undeploy <mta-id> --delete-services  # remove an MTA + its services

Troubleshooting cf deploy

Troubleshooting

Common Issues

Debugging Steps

1. Check logs: cf logs my-app --recent — always the first thing to try
2. Enable tracing: CF_TRACE=true cf push my-app — see API requests/responses
3. Check events: cf events my-app — see recent crashes, restages, scaling
4. SSH in: cf ssh my-app — inspect the running container
5. Check env: cf env my-app — verify VCAP_SERVICES and user env vars
6. API debug: cf curl /v3/apps/GUID/processes — inspect process-level details

Verifying Command Success

cf push my-app
echo $?    # 0 = success, non-zero = failure

Common Workflows

Deploy a Node.js app with a Postgres service

cf login -a https://api.example.com --sso
cf target -o my-org -s dev
cf create-service postgres standard my-db
cf push my-app -b nodejs_buildpack
cf bind-service my-app my-db
cf restage my-app

Zero-downtime deployment

cf push my-app --strategy rolling
# If something goes wrong mid-deploy:
cf cancel-deployment my-app

CI/CD pipeline pattern

cf api https://api.example.com
cf auth "$CF_USERNAME" "$CF_PASSWORD"
cf target -o my-org -s production
cf push my-app -f manifest-prod.yml --strategy rolling --no-wait

Scale based on load

cf scale my-app -i 10              # scale out to 10 instances
cf scale my-app -m 1G              # increase memory per instance
