What is Git
Git is a distributed version control system (DVCS). It is used to track changes in source code during software development, enabling developers to easily collaborate on projects. Unlike centralized version control systems, Git allows multiple contributors to work on the same project without having to share a single codebase. Additionally, it makes it easy to go back and forth between different versions of a codebase, making it simpler to troubleshoot and identify bugs. As a result, Git is an essential tool for software developers.
Understanding Git basics
1.Installing Git:
Windows: Download and install the latest version of Git for Windows from https://git-scm.com/download/win.
Mac: Download and install the latest version of Git for Mac from https://git-scm.com/download/mac.
2. Creating a Git Repository:
- Create a new directory to store your project files.
- Open the terminal or command line in your newly created directory.
- Type “git init” to initialize a new Git repository.
3. Staging and Committing Changes:
- To stage changes, use the “git add” command followed by a filename or directory:
git add <filename>
git add <directory>
- To commit changes, use the “git commit” command followed by a message:
git commit -m “<message>”
4. Creating Branches:
- To create a new branch, use the “git branch” command followed by a branch name:
git branch <branch_name>
5. Merging Branches:
- To merge branches, use the “git merge” command followed by the branch name you want to merge into the current branch:
git merge <branch_name>
6. Resolving Conflicts:
- If there is a conflict during a merge, you can use the “git diff” command to view the differences between the two branches:
git diff <branch_name>
- To resolve the conflict, edit the conflicting files and use the “git add” and “git commit” commands to stage and commit the changes.
GitLab
1. Introduction to GitLab
GitLab is a powerful version control platform that allows developers and teams to work on projects collaboratively. It provides version control, issue tracking, code review, and continuous integration and delivery (CI/CD) tools in one package. It also provides a secure environment for developers to store and share code and manage projects.
2. Creating and Managing Repositories
Creating a repository on GitLab is easy. All you need to do is log in to your GitLab account, click the ‘Create a new project’ button, and then fill out the necessary details. You can choose to make the repository either private or public and set up the desired access levels.
Once the repository is created, you can start adding files to it. You can also use the ‘Git’ tab to enable version control for the repository. This allows you to keep track of changes made to the files, as well as revert to previous versions if needed.
3. Setting Up CI/CD Pipelines
GitLab allows you to set up CI/CD pipelines for your repositories. This is done by adding a ‘.gitlab-ci.yml’ file to your repository. This file describes the steps that will be taken for each job in the pipeline, such as building, testing, and deploying the code.
Once the pipeline is configured, you can set up triggers to run the pipeline automatically when certain conditions are met, such as when changes are pushed to the repository or when a branch is merged. This allows you to automate the process of building, testing, and deploying code, ensuring that your code is always up-to-date and running smoothly.
4. Team Collaboration
GitLab also provides several tools to facilitate collaboration among team members. You can create separate groups to manage access levels, as well as assign tasks and track progress. You can also use milestones and labels to better organize your tasks, as well as use the built-in discussion boards to communicate with your team.
In addition, GitLab also provides a Wiki feature that allows you to create and share project-related information with your team. This can be useful for keeping track of project progress and discussing ideas.
Finally, GitLab also provides several tools to help you keep your code secure. You can set up branch protection rules to ensure that only certain people can make changes to certain branches, as well as use code signing to verify that the code has been signed by an authorized user. This helps to ensure that only authorized changes are made to the code.
Overall, GitLab is a powerful and versatile tool for managing and collaborating on projects. By utilizing its many features, developers can ensure that their code is secure, up-to-date, and running smoothly.
GitHub
GitHub is a code hosting platform for version control and collaboration. It is used to store and track changes in source code during software development. It allows developers to collaborate on projects, review code, and track changes.
Git is the version control system used by GitHub to store and manage source code. When developers use Git with GitHub, they can track code changes, as well as share and collaborate on code with other developers.
Using Git with GitHub, developers can create and merge pull requests. Pull requests are used to propose changes to a project, and if accepted, the changes are merged into the project’s codebase.
GitHub also provides project management features, such as issue tracking. Issues can be used to track bugs and features, or any other task related to a project. Issues can be assigned to individuals, assigned labels and milestones, and tracked over time.
Finally, GitHub also provides project analytics, such as a repository’s activity and the number of contributors to a project. This information can be used to track the progress of a project and measure its success.
Bitbucket
Bitbucket is a cloud-hosted version control system (VCS) created by Atlassian. It is used to store, manage, and share source code and other development materials. It is important in software development because it helps developers keep track of their changes and collaborate with others on projects. It also allows for easy access to the latest version of the code, making it easier to make changes and corrections when needed.
Bitbucket can be used as a version control tool by creating a version control repository. This repository can be used to keep track of different versions of a project and can be used to store the source code, documentation, and other related files. Once the repository is created, developers can commit changes to it, allowing them to easily keep track of their progress and collaborate with others. Bitbucket also provides access control, allowing developers to limit access to certain files or directories, and it provides features such as branching and merging, which make it easier to manage multiple versions of a project.
