Over the past twelve months, 831 developers contributed new code to Kubernetes. This is one of the largest open-source teams in the world, and is in the top 2% of all project teams on Open Hub.
For this measurement, Open Hub considers only recent changes to the code. Over the entire history of the project, 1768 developers have contributed.
The first lines of source code were added to Kubernetes in 2014. If this older project has had recent activity, then this project likely is consistently delivering value, and attracts sustained effort from the community.
A longer source control history in conjunction with recent activity such as with this project, may indicate that this code base and community have enough value to hold contributors' interest for a long time. It may also indicate a mature and relatively bug-free code base, and can be a sign of an organized, dedicated development team.
Note: The source code for Kubernetes might actually be older than the source control history can reveal. Many new projects begin by incorporating a large amount of source code from existing, older projects. You might be able to tell whether this is the case by looking for a rapid rise in the amount of code early in the project's history.
Kubernetes is written mostly in Go.
Across all Go projects on Open Hub, 15% of all source code lines are comments.
This holds true for Kubernetes as well. It contains the same ratio of comment lines to code lines as the majority of Go projects in Open Hub.
A high number of comments might indicate that the code is well-documented and organized, and could be a sign of a helpful and disciplined development team.
Over the last twelve months, Kubernetes has not seen any change in activity. This may be a good sign, and an indication that development is continuing at the same pace and not dropping off.
Open Hub makes this determination by comparing the total number of commits made by all developers during the most recent twelve months with the same figure for the prior twelve months. The number of developers and total lines of code are not considered.
