Configure the organizational hierarchy

What is the organizational hierarchy?​

In Moderne, an organization is a collection of related repositories. The organizational hierarchy defines how these organizations are structured and related to one another.

A pre-configured organization hierarchy streamlines work on the Moderne platform by enabling operations to target well-defined groups of repositories. For example, if Team 1 wants to run a migration on only their own repositories, they can select their team’s organization. Meanwhile, a manager overseeing both Team 1 and Team 2 could select the parent organization to run operations across both teams’ repositories.

ALL
├── VP
    └── Director
        └── Manager
           ├── Team 1
           └── Team 2

There are no strict requirements for how the organizational hierarchy must be structured. However, customers often model it after their internal reporting hierarchy.

Is the organization hierarchy mandatory?​

No. If no organization hierarchy is configured, all repositories will default to the All organization. This setup can be suitable when managing a relatively small number of repositories. However, as your repository count grows, we recommend establishing an organization hierarchy to improve structure and scalability.

How is the organization hierarchy defined?​

Organizational structure is a configured via a repos.csv file, accessible to the Agent via the file system or network. Depending on your deployment configuration, this may be done by placing the file in the same host as the agent or by using a file/network mount. The Agent can also be configured with an unauthenticated HTTP/S URI that serves the aforementioned repos.csv.

This configuration is best explained with an example. Consider an organization that consists of two teams and two directors:

All
├── Director A
|       └── Team 1
|       └── Team 2
├── Director B

The following CSV file would represent this organizational structure:

cloneUrl,branch,org1,org2,org3
"https://github.com/apache/maven-doxia","master","Team 1","Director A","ALL"
"https://github.com/Netflix/photon","main","Team 2","Director A","ALL"
"https://github.com/Netflix/ribbon","master","Director A","ALL"
"https://github.com/apache/maven-doxia","master","Director B","ALL"

In the above file, we define 5 organizations (ALL, Director A, Director B, Team 1, and Team 2) and 3 repositories. Notice that one repository can be defined multiple times if you want two distinct organizations to have access to it.

Also note that organizations on the left are children of organizations on the right. For instance, Team 1 is a child of Director A which is a child of ALL.

tip

Comma-separated files (CSV) are best manipulated using a dedicated editor such as Microsoft Excel, Google Sheets, or Apple Numbers. Here is what the above CSV would look like on Apple Numbers:

Expected format for repos.csv​

  • Use quotation marks around each value to help differentiate between the different columns.
  • A single row may not have more columns than what is defined in the first row.
  • A single repository may be associated with multiple organizations by being referenced in multiple rows. In the above example, maven-doxia is associated with both Director B and Team 1.
  • Repositories can be associated with any organization down the tree, not just the leaves. See line 4 in the csv file for an example.
warning

Org columns must start immediately after the branch column. Likewise, they must be contiguous. Do not add empty orgs so that the orgs line up with one another.

cloneUrl,branch,org1,org2,org3,org4
"https://github.com/apache/maven-doxia","master","Team 1","Director A","ALL"
# Non-contiguous series of orgs 👇 
"https://github.com/Netflix/photon","main","Team 2","","Director B","ALL"
# First org does not start immediately after the branch column 👇 
"https://github.com/Netflix/ribbon","master","","Director A","ALL"

Agent configuration​

The repos.csv source location is configured via the moderne.agent.organization.repoCsv variable. Its value may be a local path or an unauthenticated HTTP(S) URI. You can also configure how often the agent looks for changes to this file (by default it's every 10 minutes).

Environment variables:

Environment variableRequiredDefaultDescription
MODERNE_AGENT_ORGANIZATION_REPOSCSVfalseThe path to the repos.csv file that defines your organizational structure. This could also be an unauthenticated HTTP/S URI in the form of https://your-serve/repos.csv.
MODERNE_AGENT_ORGANIZATION_SERVICE_UPDATE_INTERVAL_SECONDSfalse600The number of seconds that the agent should wait before it checks for an update to your repos.csv file.

Example:

docker run \
# ... Existing variables
-e MODERNE_AGENT_ORGANIZATION_REPOSCSV=/Users/MY_USER/Documents/repos.csv \
# ... Additional variables
