Edge Delta with Non-Standard Log Folder in Kubernetes

Overview

In Kubernetes, different distributions might have varying default log file locations, although a commonly used path for system and container logs is /var/log/containers. Variations can occur due to different setups or customization options provided by different Kubernetes distributions. For some Kubernetes distributions, /docker/containers or /var/lib/docker/containers is used.

Understanding the locations of default log folders for different Kubernetes distributions is vital for several reasons. Firstly, for monitoring and management, knowing where logs are stored is critical for setting up log observation tools. This knowledge enables more effective troubleshooting and monitoring of systems when issues arise.

Secondly, in the realm of automation and configuration, being aware of log file locations is essential. This understanding aids in the development of automation scripts and the configuration of management tools or deployment pipelines, especially when integrating logging agents or adhering to organizational policies regarding data handling.

Security and compliance constitute another key area impacted by log file locations. Different paths may introduce varying security considerations, particularly in terms of access control. By being aware of these locations, appropriate permissions can be set, and compliance with rules designed to protect sensitive data can be enforced effectively.

Lastly, performance optimization can be influenced by log storage locations. The storage of logs can significantly impact I/O resources. Hence, knowledge of these locations allows for strategic decisions regarding storage solutions, such as deploying faster disks or segregating logs into different storage volumes to minimize I/O conflicts.

Configure for a Non-Standard Log Folder

For custom Kubernetes deployments, you may need to update the mountPath to match the actual path of the container log folder. In these cases, you must update the mountPath in the manifest file (edgedelta-agent.yml) to match the actual path of the container log folder.
