Developed and delivered a Container Memory Limit Detection feature for the zulip/zulip repository, enabling accurate detection of memory limits in containerized environments. The solution prioritized cgroup v1 and v2 memory limits, with a fallback to system memory, to ensure operations remain within safe resource boundaries and prevent out-of-memory conditions. This work improved the reliability of container deployments, particularly in heterogeneous environments with varying constraints. The implementation leveraged Puppet, Ruby, and Facter, integrating seamlessly with existing DevOps workflows. Code review and repository maintenance were also performed to validate compatibility and prepare for broader adoption across containerized system administration scenarios.
