CumulusCI Aids Scripted Integration and Deployment for Salesforce Devops

CumulusCI was recently added to the List of Salesforce-first devops solutions. Here is a quick overview of why solution architects should explore CumulusCI when formulating a practical devops strategy.

CumulusCI is a Project

CumulusCI is a Salesforce-first, free open-source software (FOSS) project sponsored by, which is a division of the mothership, Salesforce, Inc.’s mission is to support the non-profit community’s use of Salesforce as a donation and management platform. has a long history of publishing freely available toolkits and other useful items on GitHub and the Salesforce AppExchange that are useful to the entire Salesforce community, not just the non-profit sector.

CumulusCI has excellent documentation and a Trailhead module:

According to Salesforce officials, the upcoming release of Salesforce DevOps Center should not impact existing CumulusCI users. DevOps Center may add additional release management capabilities to CumulusCI users. CumulusCI is a FOSS project and is not part of the Salesforce master agreement.

CumulusCI Is a Scripting CLI

One way to understand CumulusCI’s command line interface, called CCI-CLI, is that it is a command line interface that runs best on a Linux host and it doesn’t have server component, like some other devops tools. It is used in addition to SFDX-CLI as a scripting tool.

To drill into the CumulusCI solution architecture, take a look at the Command Server in this representation of an ideal way to build a Salesforce devops solution.

And let us go further into the Command Server and examine its components. The command server is, in this case, a compute cluster that launches Docker containers to run scripts.

Here is how CumulusCI works in this type of environment. Scripts use the CCI-CLI command line interface to perform source-based operations on a Salesforce org. The Script Dispatcher receives parameterized commands from an enterprise developer or other automated process and then retrieves the script for execution.

The script dispatcher then sends a job to execute a script in a runner container. The runner container is a Docker container that installs all the operating system tools, components and CLIs needed by the scripts. The runner also pulls in the repository that has all of the Salesforce metadata required for a deployment. Next the container executes the script with the CCI-CLI commands.

Look back at the Salesforce Devops System Integration diagram. The runner executes the script with CCI-CLI commands, and then Salesforce API network calls and other commands through the enterprise network to Salesforce for execution. It is in this way that Command Servers are an essential part in performing Salesforce devops.

CumulusCI Is An Essential Tool

Cumulus CI is blessed with community, documentation, ease of use. CumulusCI is highly recommend to be evaluated by Salesforce solution architects as part of their devops solution.
