Dockerlabs

Devtools toolkit for Docker-related workflows — check, validate, generate, format, lint, explain, convert, template, diff, preview, fix, and report on Docker configurations. All entries are logged locally with timestamps for full traceability.

Commands

Command	Description
dockerlabs check <input>	Check a Docker configuration or record a check entry
dockerlabs validate <input>	Validate a Docker setup or record a validation entry
dockerlabs generate <input>	Generate Docker artifacts or record a generation entry
dockerlabs format <input>	Format Docker files or record a format entry
dockerlabs lint <input>	Lint Dockerfiles or record a lint entry
dockerlabs explain <input>	Explain Docker concepts or record an explanation entry
dockerlabs convert <input>	Convert Docker configurations or record a conversion entry
dockerlabs template <input>	Manage Docker templates or record a template entry
dockerlabs diff <input>	Diff Docker configurations or record a diff entry
dockerlabs preview <input>	Preview Docker setups or record a preview entry
dockerlabs fix <input>	Fix Docker issues or record a fix entry
dockerlabs report <input>	Generate reports or record a report entry
dockerlabs stats	Show summary statistics across all entry types
dockerlabs export <fmt>	Export all data (json, csv, or txt)
dockerlabs search <term>	Search across all log entries
dockerlabs recent	Show the 20 most recent activity entries
dockerlabs status	Health check — version, data dir, entry count, disk usage
dockerlabs help	Show help with all available commands
dockerlabs version	Show current version (v2.0.0)

Each command (check, validate, generate, format, lint, explain, convert, template, diff, preview, fix, report) works in two modes:

• No arguments: displays the 20 most recent entries from that command's log
• With arguments: records the input with a timestamp and appends to the command's log file

Data Storage

All data is stored locally at ~/.local/share/dockerlabs/. Each action is logged to its own file (e.g., check.log, lint.log, generate.log). A unified history.log tracks all operations. Use export to back up your data anytime in JSON, CSV, or plain text format.

Requirements

• bash 4+ (uses set -euo pipefail)
• Standard Unix utilities (wc, du, grep, tail, sed, date)

When to Use

• Tracking Docker configuration checks, validations, and linting results
• Logging Docker file generation, conversion, and formatting operations
• Keeping an audit trail of Docker troubleshooting and fixes
• Exporting Docker operation history for reporting or compliance
• Searching past Docker operations by keyword

Examples

# Record a Dockerfile lint result
dockerlabs lint "Dockerfile uses latest tag — pin to specific version"

# Record a validation check
dockerlabs validate "docker-compose.yml syntax OK, 3 services defined"

# Generate a template entry
dockerlabs generate "multi-stage build for Node.js app"

# View recent lint entries
dockerlabs lint

# Search for entries mentioning "nginx"
dockerlabs search nginx

# Export all data as JSON
dockerlabs export json

# Check overall health
dockerlabs status

# View summary stats
dockerlabs stats
