CI/CD Tool

CI/CD tool

A CI/CD tool runs tests and builds your app every time you change code. It catches mistakes early, so broken parts do not reach users. The tool can also package your app and send it to a test place or to the real site. This makes work steady and safe, because each step is clear, repeatable, and shared with the team.

How do I set up my first pipeline?

Create a new pipeline file in your project and pick simple steps. Start with install, test, and build. Tell the tool to run on each push to the main branch. Commit the file, then check the dashboard to watch each job run and fix any red marks.

What stages should I include?

• Add install to fetch dependencies.
• Run test to check logic.
• Add build to create artifacts.
• Use deploy to publish safely.

How do secrets stay safe?

Store keys in the tool’s secret vault, not inside files. Give each key the smallest rights needed. Use protected branches so only reviewed changes can touch deploy steps. Rotate keys on a schedule and remove ones you no longer use.

Hosted service or self hosted server?

A hosted service is simple to start, needs no hardware, and scales on demand. A self hosted server gives full control and can run inside your network. Small teams often pick hosted to move fast. Larger or private projects may choose self hosted for control and cost predictability.

How do I speed up runs?

Cache dependencies so the tool downloads less each time. Split long jobs into parallel steps. Run quick tests on every push and slow tests on a schedule. Keep the pipeline file tidy, with short names and clear comments.

What if a build turns red?

Open the logs on the failing step and read from the top. Look for the first clear error, not the last noisy line. Reproduce the issue on your computer if possible, then push a small fix. Add a test that would catch this bug next time to prevent repeats.
