The Core Concepts of Streamline
The core concepts of Streamline revolve around branching and continuous integration (CI). Streamline starts with two types of branches: trunk, which represents the single source of truth, and feature, which represents new code. Developers branch off trunk to work on a feature, make changes, and raise a pull request back into trunk. Continuous integration involves an automated pipeline triggered by a pull request, running all functional tests, creating a Docker image, and deploying it to a test environment. The CI process ensures code quality and enables continuous deployment.
Branching Strategy
In Streamline, the branching strategy includes two main branches: trunk and feature. The trunk branch serves as the main branch, representing the stable and production-ready code. On the other hand, the feature branches are created by developers to work on specific features or bug fixes. These branches are later merged back into trunk after the changes have been reviewed and tested. By following this branching strategy, Streamline ensures a streamlined and organized development process.
Continuous Integration (CI)
Continuous integration plays a vital role in Streamline. It involves automatically building, testing, and merging code changes into the main branch. When a developer completes work on a feature branch, they create a pull request to merge it into the trunk. This triggers the CI pipeline, which includes various automated tests such as unit tests, integration tests, and end-to-end tests to ensure code quality. If the tests pass, the changes are merged into the trunk, enabling continuous deployment and maintaining a stable codebase.
To illustrate the core concepts of Streamline visually, refer to the following table:
| Core Concepts | Description |
|---|---|
| Branching | Streamline uses a trunk and feature branch strategy to manage code changes and ensure a stable codebase. |
| Continuous Integration (CI) | Automated testing and merging of code changes into the main branch to maintain code quality and enable continuous deployment. |
| Continuous Deployment | The automatic deployment of tested and approved code changes to production or staging environments. |
By understanding and implementing these core concepts, development teams can effectively streamline their processes and improve collaboration, code quality, and software delivery.
Continuous Integration in Streamline
Continuous integration is a fundamental aspect of the Streamline approach to software development and deployment. With Streamline, we leverage an automated pipeline triggered by pull requests to ensure efficient integration and validation of code changes. Through this automated pipeline, we can run a series of functional tests and create a Docker image that encapsulates the tested application.
The continuous integration process starts with developers raising a pull request to merge their code changes into the main trunk. Once the pull request is triggered, the automated pipeline kicks in and executes the functional tests to validate the code changes. These tests are designed to ensure that the application functions as expected and meets the specified requirements.
Upon successful completion of the functional tests, a Docker image is generated containing the tested application. This Docker image serves as a versioned representation of the application, ensuring that we have a releasable version that can be seamlessly deployed across different environments.
We also incorporate an image registry where the generated Docker image is uploaded. This allows for easy storage, management, and distribution of the Docker image, facilitating its deployment to various test environments.
“Continuous integration in Streamline enables us to validate code changes, create versioned Docker images, and ensure that the application is ready for deployment across different test environments.”
By adopting continuous integration in Streamline, we can establish a robust and streamlined development process. It enables us to identify and address issues early in the development lifecycle, ensuring code quality and reducing the risk of introducing bugs or regressions.
As shown in the image above, the automated pipeline in Streamline serves as the backbone of our continuous integration process. It automates the execution of functional tests and the creation of Docker images, providing a reliable and efficient means of ensuring the quality and readiness of our code for deployment.
Managing Merges in Streamline
In Streamline, merging code requires meeting two important conditions to ensure compatibility, quality, and the release of a reliable version of the application. Let’s explore these merge conditions, which involve the CI pipeline, feature branch, and trunk.
Merge Conditions
In order to merge code into the trunk successfully, two conditions must be met:
- The CI Pipeline: The Continuous Integration (CI) pipeline must be executed and pass all automated functional tests. This ensures that any code changes undergo rigorous testing and meet the required quality standards. Only when the CI pipeline runs successfully is the code deemed ready for integration.
- Feature Branch and Trunk: The feature branch, where developers work on new code, must be up-to-date with the trunk. Keeping the feature branch synchronized with the trunk ensures that the latest changes and updates are incorporated seamlessly. If there are new commits pushed to a branch that has an open pull request, the CI pipeline must be rerun to incorporate these changes. This ensures that the integration of the feature branch with the trunk incorporates the most recent updates from all contributors.
Once both these conditions are fulfilled, the feature branch can be fast-forward merged into the trunk, consolidating all the changes made by different developers. This merging process guarantees code compatibility, quality, and a releasable version of the application.
Example Merge Process
To illustrate the merge process in Streamline, let’s consider the following scenario:
Feature Branch: A developer creates a feature branch named “user-authentication” to implement a new user authentication feature.
CI Pipeline: The developer initiates a pull request to merge the feature branch into the trunk. The CI pipeline is triggered, running all automated functional tests and creating a production-ready Docker image. If any failure occurs during this pipeline, the developer must address the issues and rerun the CI pipeline.
Merge into Trunk: Once the CI pipeline passes and the feature branch is up-to-date with the trunk, the feature branch can be merged into the trunk. This integration consolidates the new code with the existing codebase, ensuring compatibility and a reliable version of the application.
By following these merge conditions, Streamline enables smooth collaboration among developers, facilitates the integration of new features, and ensures a robust and releasable codebase.

Continuous Deployment in Streamline
When it comes to deploying applications in Streamline, continuous deployment is the key. This process involves leveraging versioned Docker images to seamlessly deploy the latest updates to your application. Once the code is merged into the trunk, the Docker image representing the new version is tagged and deployed into the designated “Trunk” environment. This controlled deployment pipeline ensures that the application is continuously updated and available for use by end-users.
Versioning is a crucial aspect of continuous deployment in Streamline. It allows for easy tracking and management of specific versions of the application. By calculating the version number based on the most recent tag or versioned Docker image, you can maintain a clear and organized versioning system that facilitates efficient deployment and troubleshooting.
The deployment pipeline in Streamline ensures that every revision of your application goes through a standardized process, guaranteeing consistency and quality. The use of Docker images enables you to create self-contained packages that include all the dependencies required to run your application. This eliminates compatibility issues and further streamlines the deployment process.
With Streamline’s continuous deployment approach and the use of versioned Docker images, you can confidently deploy your application updates, knowing that they have been thoroughly tested, versioned, and are ready for production use.
