Docker Pro Diagnostic
Advanced log analysis for Docker containers using signal extraction.
Why use this skill?
Instantly troubleshoot failing Docker containers with Docker Pro Diagnostic. Automatically extract, analyze, and resolve errors with advanced log processing.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/mkrdiop/docker-diagWhat This Skill Does
The Docker Pro Diagnostic skill is an advanced troubleshooting tool designed to streamline the investigation of failing or misbehaving Docker containers. By leveraging a custom signal extraction script, it automates the tedious process of sifting through massive log files. When activated, the skill executes a specialized Python processor directly against the target container, identifying key error patterns, stack traces, and system-level exceptions. It then synthesizes this raw technical data into human-readable insights, distinguishing between application-level bugs and infrastructure-related bottlenecks like Out-Of-Memory (OOM) events or network timeouts.
Installation
To integrate this skill into your OpenClaw environment, ensure you have the OpenClaw agent installed and permissions to execute Docker commands on the host machine. Run the following command in your terminal:
clawhub install openclaw/skills/skills/mkrdiop/docker-diag
Once installed, the agent will index the log_processor.py utility, making it available for immediate use during your troubleshooting workflows.
Use Cases
- Production Outages: Quickly diagnose why a production container repeatedly restarts (CrashLoopBackOff).
- Performance Bottlenecks: Identify if application slowdowns are caused by memory limits or database connection pool exhaustion.
- Deployment Verification: Automatically verify that a newly deployed microservice initialized correctly after a code push.
- Error Pattern Recognition: Discover recurrent error strings across distributed services during high-traffic windows.
Example Prompts
- "Why is my container failing? Check the logs for web-server-01 and tell me what's wrong."
- "Analyze the logs for auth-service and suggest a fix for the memory issues I've been seeing."
- "Run a diagnostic on the payment-gateway container; it seems to be crashing every 5 minutes."
Tips & Limitations
- Permissions: Ensure the OpenClaw agent user has sufficient privileges to access the Docker daemon socket (
/var/run/docker.sock). - Log Volume: For containers with extremely high log output, the extraction process may take several seconds. Consider using log rotation in your Docker configuration to keep files manageable.
- Scope: This skill is focused on log analysis; it does not perform automated code patches or infrastructure re-provisioning. Always review suggested fixes before applying them to production environments.
