02. CI & CD in practice

---

Continuous Integration(CI) & Continuous Deployment(CD)

---

Prerequisites

1. Understand the step of CI/CD

---

In pratice

1. Add new option whether the github.io post have a the name of title or not?

After build site step, adding new option. In this case, for simple example and practice, i will add simple option whether the github post have a title or not.

2. Compare Before and After?

Before

The process is $ Build site \rightarrow Test site $.

So i wanna add new option “check in common”

Current state .

After

Now i will add new option “check in common” between build site and Test site.

      - name: Build site
      ...

      # new option
      - name: Check in common
        run: |
          echo "Check in common setting..."

          for file in _posts/*.md; do
            echo "Checking $file"

            if ! grep -q "^title:" "$file"; then
              echo "Missing title in $file"
              exit 1
            fi
          done

          echo "Check in common passed"

      - name: Test site
      ...

New state and processing

Finish the new process

Change the structure CI pipeline

2. If the “check in common” step have issue from forgetting the title or wrong world

Intentionally Add typo within “title”

CI process fails on “check in common” process and Fail to deploy

After correct the name of title, it works
