Git Components ⚙️Part I

1. Blobs ⏹️ - immutable Git units that represent file 📂 contents.

2. Trees 🌲- structures the directory 🗃️ and points to other blobs and trees to create a directory hierarchy 📃.

3. Commits 🧑‍💻 - A commit points to a tree object that captures a snapshot of a repository by storing details (author, commit date, and previous commit info).

4. Tags 🏷️- acts as a unique identifier for a commit and stores a repository's milestones 🏆.

💫Which role does Git play in Continuous Integration?

⚙️Git is a distributed version control system to keep the project code 💻 and datasets 🗄️ up-to-date.

💻What is continuous integration?

Continuous integration is an iterative process where the developer commits to the repository 🗃️. The CI system tests and validates the commits so that they become integrated into the code project.

💻Integrating Git within the CI workflow 🔁

⚙️Git automates the build and testing phases using the following steps📄:

1. Select a CI tool 🔧 (Jenkins, CircleCI, Travis CI, or GitLab).

2. Set up a Git repository and push the code onto the server 📶.

3. Link up the Git repository with the chosen CI tool ⚙️.

4. ⚙️Configure the CI server to watch the changes made to Git.

5. When detecting changes 🧑‍💻, the CI server will run an automated build script 💻.

6. The build script will execute a series of tests ✅❌.

7. An email 📨 notification will be sent to the development team after the automated continuous integration tests finish 🎯.

8. 🧑‍💻A reviewer will determine whether to merge the code into the repository.

💡What should you do as a team member during the CI cycle?

• ✅Commit frequently to the repository 📶.

• ✅Create documentation 🗃️ of your changes to ensure consistency and allow the code to become reproducible for future developers 🧑‍💻.

• ✅Learn and understand the core CI principles 📖 and familiarize yourself with the tools ⚙️.

• ✅Keep in sync with the most recent updates from the repository 📶 to minimize the risks of a conflict.

• ✅Fix broken builds ⚒️ as soon as possible to allow other team members to integrate their changes and to keep the CI workflow cycle.

• ✅Schedule meetings 🗓️ with team members for code reviews 🗣️ and coordinate changes over essential components ⚙️.

• ✅Run local tests to fix ⚙️as many errors as possible before committing the code 💻.

• ✅Write meaningful commit messages 📖 to help other members 🧑‍💻 understand why you made this update ⚙️.
