Docker & DevOps

Create a production-ready Dockerfile for Node, Python, Go, Java, PHP, .NET or a static site, including multi-stage builds.

Generate a .dockerignore for your stack so images stay small and secrets stay out.

Generate a docker-compose.yml with your app, a database (PostgreSQL, MySQL or MongoDB) and Redis.

Build a docker run command with ports, environment variables, volumes, restart policy and network.

Check a docker-compose.yml for YAML errors, missing images, bad ports and undefined dependencies.

Create a Deployment, Service and optional Ingress YAML for your container with replicas, ports and resource limits.

Generate YAML for a ConfigMap, Secret, Namespace, PVC, CronJob, HorizontalPodAutoscaler or Ingress.

Generate an Nginx server block for a static site, single-page app, reverse proxy or PHP, with HTTPS and gzip.

Generate an Apache virtual host, reverse proxy block, or .htaccess rules for HTTPS, SPA routing and www redirects.

Create an ecosystem.config.js for PM2 with cluster mode, environment variables and memory restart.

Create a systemd unit file for your app with working directory, user, restart policy and environment.

Pick read, write and execute for owner, group and others to get the octal chmod number and symbolic form — or decode one.

Convert Linux file permissions between octal numbers like 644 and symbolic form like rw-r--r--.

Build a chown command to change a file's owner and group, with recursive and symlink options.

Build an ssh command with port, key, jump host and port forwarding, plus the matching ~/.ssh/config entry.

Build an scp command to upload or download files and folders over SSH.

Build an rsync command with delete, dry-run, excludes and a custom SSH port.

Turn KEY=value lines into a clean .env, a safe .env.example, JSON, Docker flags, Compose environment and shell exports.

Clean up a messy .env file: trim spaces, upper-case names, remove duplicates, sort and quote values properly.

Generate a build-and-test pipeline for GitHub Actions, GitLab CI or Bitbucket Pipelines for Node, Python, Go or Java.
