The pcf utility provides a command line interface to Ops Manager for the purpose of deploying and testing tiles. Its primary reason for existence is to enable Ops Manager access from CI pipelines, but developers also find it convenient to use this CLI rather than the Ops Manager UI.
The pcf utility also allows you to test your tile’s BOSH errands directly from your CLI, without going through Ops Manager and BOSH. This greatly reduces the time it takes to deploy/test each iteration of your software components.
The pcf utility comes bundled with the Tile Generator tool. To install the pcf utility, follow the Tile Generator installation instructions.
The pcf utility looks for a file called metadata in the current directory. This file is expected to provide the URL and credentials to connect to Ops Manager, in the following format:
---
opsmgr:
url: https://opsmgr.example.com
username: admin
password: <redacted>
The reason for this file naming is because this is how Concourse passes credentials of a “claimed” Ops Manager pool resource to the CI pipeline scripts. For interactive use, this means that you will have to create a metadata file in the directory where you run the pcf command.
VMware recommends that you do not create this file inside your git or other version control system repository, as you do not want to accidentally commit these credentials to version control.
The pcf utility implements many different commands. To see available commands:
$ pcf --help
Usage: pcf [OPTIONS] COMMAND [ARGS]...
Options:
--help Show this message and exit.
Commands:
apply-changes
cf-info
changes
configure
delete-unused-products
import
install
is-available
is-installed
logs
products
settings
target
test-errand
uninstall
To see which products are currently available and installed in Ops Manager:
$ pcf products
- p-bosh 1.7.0.0 (installed)
- cf 1.7.0-build.258 (installed)
- test-tile 0.3.95
To test if a specific product is available or installed from within a script:
$ pcf is-available test-tile && echo "Product test-tile is available"
$ pcf is-installed test-tile && echo "Product test-tile is installed"
You can retrieve the settings for a specific product (this will give you a lot of json):
$ pcf settings test-tile
{
"network_reference": "669e213111ab5aa1008a",
"guid": "test-tile-be3e50cf26c530acca6e",
"jobs": [

After your software works and correctly deploys using test-errand, you can go through the real Ops Manager deployment process from the CLI, as you would normally do through the Ops Manager UI.
Import your .pivotal file into Ops Manager:
$ pcf import sample/product/test-tile-0.0.2.pivotal
Install the uploaded version of your product:
$ pcf install test-tile 0.0.2
Where you would normally configure the tile settings in the UI, the configure command lets you pass in any user-specified properties as a .yml file. This command also sets the stemcell for the tile to the same one used by VMware Tanzu Application Service for VMs (TAS for VMs), to avoid the need to upload a tile-specific stemcell.
$ pcf configure test-tile sample/missing-properties.yml
- Using stemcell bosh-vsphere-esxi-ubuntu-trusty-go_agent version 3215
The property file looks like this:
---
customer_name: Jimmy's Johnnys
street_address: Cartaway Alley
city: New Jersey
country: US
username: SpongeBob
password: { 'secret': Square'Pants }
app2:
persistence_store_type: none
# In Ops Manager (formerly PCF) 1.8+, BOSH-job-specific configuration is supported:
jobs:
a_job:
# Job resource configuration:
resource_config:
persistent_disk:
size_mb: "10240"
# Job-specific property configuration:
job_property: property_value
You must define any secret type property value as a hash, in curly brackets. Specifying a simple string value for a field of this type results in a 500 System Error being returned from pcf configure. The secret type property values can contain special characters.

pcf apply-changes automatically tails the logs for the installation process it started. If this gets canceled for any reason, you can tail the logs of the most recent installation:
$ pcf logs
To uninstall a tile:
$ pcf uninstall test-tile
If you accumulate a lot of uninstalled tiles or old versions, you can clean up Ops Manager’s available products (and disk space):
$ pcf delete-unused-products
