Note: MongoDB is not installed by default with the product installation
for Kubernetes and OpenShift platforms. You are expected to install it separately. It is
highly recommended to allocate one node for MongoDB and three nodes are for the product
installation for better performance and stability of the application.
MongoDB requirements
MongoDB requirements
Unlike Docker Compose, the MongoDB is not installed by default and you are expected to
install it separately, configure, and maintain the database. As a guideline, use the
following specifications:
- 2 CPU Cores
- 8 GB RAM minimum (16 GB recommended)
- 20 GB storage minimum (50 GB recommended)
Note: MongoDB replica sets are supported if configured by the
customer. Additional details are found here.
The figure below provides storage guidelines over time and contributors to total size.

For the above graph, estimates are calculated using real production data and with the
following assumptions:
- Each onboarded application has at least one associated value stream.
- Over 300 issues are created and imported per year with associated Pull requests (PRs) and commits.
- Over 20 builds and deployments are captured per application per day.
- Five quality metrics are captured per build with examples including functional test results, code coverage, vulnerability scans, and so forth.
The following table details growth estimates over time based on number of apps per
year.
Number of apps per year | Day 1 (GB) | Year 1 (GB) | Year 2 (GB) | Year 3 (GB) |
---|---|---|---|---|
1 | 0.5 | 4 | 8 | 13 |
5 | 2 | 10 | 17 | 25 |
10 | 5 | 16 | 28 | 41 |
25 | 12 | 37 | 62 | 88 |
The following table details estimates for environments based on number of apps.
Environment | Number of apps | Size (GB) |
---|---|---|
POC | 1-3 | 20 |
Pilot | 5-10 | 30 |
Typical onboarding | 20-30 | 70 |
