DevOps Tools

Review a deployment configuration

Check a Compose document against the official schema and Kubernetes manifests against versioned schemas, then validate the final merged configuration with the native tools.

• Docker Compose Validator — Validate Compose and inspect a service dependency graph.
• Kubernetes Manifest Validator — Validate common Kubernetes resources and local CRD schemas.
• GitHub Actions Validator — Check workflow structure, expressions and job dependencies.

Check repository ignore rules

Generate a starting rule set, then test representative paths and negated exceptions. Verify the final result with Git in your repository, including nested rules and tracked files.

• .gitignore Generator — Combine .gitignore templates and test paths.
• Gitignore Tester — Test ignore rules, negations and repository paths.

Review a scheduled job

Build or explain a cron expression and inspect upcoming run times in the chosen time zone. Pay attention to day-of-month and day-of-week semantics, daylight-saving changes, and whether the destination accepts five or six fields.

• Cron Expression Generator — Build or explain cron schedules, with next run times.
• Private Code Explainer — Explain regex, Cron and SQL errors in plain language.

Set file permissions

Translate between octal and symbolic modes and see what owner, group and others can do. Permission effects differ between files and directories, and special bits such as setuid need care.

• Chmod Calculator — Convert permissions between octal and rwx notation.

Move a local command into configuration

Convert a Docker run command into Compose YAML, transform environment variables and select gitignore templates. Check paths, secrets and unsupported flags before committing the generated files.

• Docker Run to Compose — Turn docker run commands into a compose.yaml file.
• .env to JSON — Convert .env files to JSON, YAML, Docker or Kubernetes.
• .gitignore Generator — Combine .gitignore templates and test paths.

Read the actual schedule, not only its description

A step such as */45 in the minute field runs at :00 and :45 each hour, not at evenly spaced 45-minute intervals. Inspect next-run times and test with the scheduler that will run the job. Different cron implementations also differ in supported extensions.

Generated configuration does not validate a deployment

Compose conversion cannot determine whether an image exists, a mount path is correct or a published port should be exposed. Likewise, gitignore rules do not remove files already tracked by Git. Review output with the native tools before applying it.
