From a Jenkins automation point of view. Here are some key aspects to be aware of.
- Authentication: GitHub uses Personal Access Tokens (PATs) for authenticating Jenkins, while Bitbucket uses OAuth tokens. You’ll need to generate and configure the appropriate token for GitHub access in your Jenkins.
- Branch triggers: GitHub supports webhook triggers for specific branches and tags, similar to Bitbucket. Ensure your Jenkins jobs are configured to use the relevant webhook URL and trigger conditions.
- Pull request triggers: While both platforms offer pull request triggers for builds, the specific API endpoints and parameters might differ slightly. Review the GitHub API documentation for Jenkins integration to adjust your configurations.
- Code hosting: Your Jenkins pipelines will need to be updated to point to the GitHub repository instead of Bitbucket for pulling code. Ensure you have the correct URL and credentials configured.
- Branching strategy: Consider if your branching strategy needs any adjustments. GitHub offers features like protected branches and branch protection rules that might require adaptation compared to Bitbucket.
- Pull request reviews and approvals: If you previously relied on Bitbucket’s pull request review and approval features for triggering builds, you might need to configure similar workflows in GitHub.
- Security: Review and update your security settings for GitHub access in Jenkins, including PAT permissions and webhook configurations.
- Plugins: Some plugins you might be using for Bitbucket integration might not have direct equivalents for GitHub. Explore compatible alternatives or consider custom scripting solutions.
- Documentation: Update your CI/CD documentation and scripts to reflect the new GitHub integration and repository locations.
- Testing and validation: Thoroughly test your CI/CD pipeline after transitioning to GitHub to ensure everything is working as expected.
