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 | Check a Docker configuration or record a check entry | | dockerlabs validate | Validate a Docker setup or record a validation entry | | dockerlabs generate | Generate Docker artifacts or record a generation entry | | dockerlabs format | Format Docker files or record a format entry | | dockerlabs lint | Lint Dockerfiles or record a lint entry | | dockerlabs explain | Explain Docker concepts or record an explanation entry | | dockerlabs convert | Convert Docker configurations or record a conversion entry | | dockerlabs template | Manage Docker templates or record a template entry | | dockerlabs diff | Diff Docker configurations or record a diff entry | | dockerlabs preview | Preview Docker setups or record a preview entry | | dockerlabs fix | Fix Docker issues or record a fix entry | | dockerlabs report | Generate reports or record a report entry | | dockerlabs stats | Show summary statistics across all entry types | | dockerlabs export | Export all data (json, csv, or txt) | | dockerlabs search | 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
