DevOps Daily Tips
Bite-sized, actionable DevOps tips you can apply immediately. One new tip every day.
All Tips
Hot-Reload Containers in Dev with Docker Compose Watch
Stop manually rebuilding containers every time you change a file — let Compose Watch do it for you.
Validate Terraform Variables at Plan Time
Catch bad variable values at plan time instead of waiting for the cloud provider to reject them during apply.
Share Build Outputs Between CI/CD Jobs with Artifacts
Artifacts let you pass build outputs between jobs so you build once and deploy the exact same binary everywhere.
Extract and Transform Text with awk
awk lets you slice, filter, and transform text data in one line — no scripts or spreadsheets needed.
Run Setup Tasks Before Your App with Init Containers
Init containers guarantee your dependencies are ready before your app starts.
Save Hours with Custom Git Aliases
Git aliases turn multi-word commands into quick shortcuts, saving you hundreds of keystrokes every day.
ARG vs ENV in Dockerfiles — The Key Difference
Mixing up ARG and ENV means your config either disappears at runtime or leaks into your image.
Understand Terraform State Before It Bites You
Terraform state is the single source of truth for your infrastructure — mismanage it and you lose control.
Securely Manage Secrets in GitHub Actions
One leaked API key can cost thousands — GitHub Actions secrets keep your credentials encrypted and safe.
Create and Manage Services with systemd
systemd lets you run your apps as managed services that start on boot, restart on failure, and log automatically.
Zero-Downtime Deploys with Rolling Update Strategy
Rolling updates let you deploy new versions with minimal or zero downtime when properly configured.
Catch Mistakes Before They're Committed with Git Hooks
Pre-commit hooks automatically catch bugs, lint errors, and formatting issues before they enter your codebase.
