# Trunk Based Development

 

Trunk based development is a software development workflow that involves merging small, frequent updates to a core trunk or main branch. It is a common practice among DevOps teams and is required for continuous integration. In this article, we will discuss the key concepts, best practices, and drawbacks of trunk based development, as well as its comparison to other development workflows.

 

## Key Concepts

 

The key concept of trunk based development is merging small, frequent updates to a core trunk or main branch. This ensures that the main branch is always release-ready and that conflicts are minimized. To ensure that the main branch remains stable, developers should not merge changes to the trunk until they have verified that they can build successfully. This ensures that the main branch is always in a releasable state.

 

Continuous integration is another key concept of trunk based development. This involves integrating code changes into the main branch as frequently as possible. This helps to identify and resolve conflicts early on and ensures that the main branch is always up-to-date.

 

Building and testing before merging is also an important concept of trunk based development. Developers should ensure that their changes can be built and tested successfully before merging them into the main branch. This helps to ensure that the main branch remains stable and that conflicts are minimized.

 

## Best Practices

 

Code reviews are an important best practice in trunk based development. Code reviews help to ensure that code changes are of high quality and that they adhere to the team's coding standards. Code reviews also help to identify potential issues and conflicts early on, which helps to minimize the risk of breaking the main branch.

 

Feature flags are another best practice in trunk based development. Feature flags allow developers to release new features to a subset of users, which helps to minimize the risk of breaking the main branch. Feature flags also allow developers to test new features in a production-like environment before releasing them to all users.

 

Canary releases are another best practice in trunk based development. Canary releases involve releasing new features to a small subset of users before releasing them to all users. This helps to identify and resolve issues early on and ensures that the main branch remains stable.

 

Rollback strategies are also an important best practice in trunk based development. Rollback strategies help to ensure that the main branch can be rolled back to a previous state if necessary. This helps to minimize the risk of breaking the main branch and ensures that the team can respond quickly to any issues that arise.

 

## Drawbacks

 

One of the main drawbacks of trunk based development is the risk of breaking the main branch. Because developers are merging changes directly into the main branch, there is a risk that a change will break the main branch and cause issues for all users. To minimize this risk, developers should ensure that they have tested their changes thoroughly before merging them into the main branch.

 

Another drawback of trunk based development is the need for frequent communication and collaboration. Because developers are merging changes directly into the main branch, it is important that they communicate with each other and collaborate effectively to ensure that the main branch remains stable.

 

Finally, trunk based development can also lead to conflicts and merge issues. Because developers are merging changes directly into the main branch, there is a risk that conflicts will arise when two developers make changes to the same file. To minimize this risk, developers should communicate effectively and ensure that they are not making conflicting changes to the same file.

 

## Comparison to Other Development Workflows

 

Trunk based development is often compared to other development workflows, such as feature branching, Gitflow, and continuous delivery. Feature branching involves creating separate branches for each feature or bug fix, which can lead to conflicts and merge issues. Gitflow is a branching model that involves creating separate branches for features, releases, and hotfixes. Continuous delivery involves releasing code changes to production as frequently as possible. Trunk based development is often preferred over these other workflows because it is simpler and easier to manage.

 

## Conclusion

 

Trunk based development is a software development workflow that involves merging small, frequent updates to a core trunk or main branch. It is a common practice among

 

# 트렁크 기반 개발

트렁크 기반 개발은 소규모의 빈번한 업데이트를 코어 트렁크 또는 메인 브랜치에 병합하는 것과 관련된 소프트웨어 개발 워크플로입니다. 이는 DevOps 팀 사이의 일반적인 관행이며 지속적인 통합에 필요합니다. 이 기사에서는 트렁크 기반 개발의 주요 개념, 모범 사례 및 단점과 다른 개발 워크플로와의 비교에 대해 설명합니다.

## 주요 개념

트렁크 기반 개발의 핵심 개념은 코어 트렁크 또는 메인 브랜치에 대한 작고 빈번한 업데이트를 병합하는 것입니다. 이렇게 하면 기본 분기가 항상 릴리스 준비가 되고 충돌이 최소화됩니다. 기본 분기가 안정적으로 유지되도록 하려면 개발자가 성공적으로 빌드할 수 있음을 확인할 때까지 변경 사항을 트렁크에 병합해서는 안 됩니다. 이렇게 하면 주 분기가 항상 해제 가능한 상태가 됩니다.

지속적인 통합은 트렁크 기반 개발의 또 다른 핵심 개념입니다. 여기에는 가능한 한 자주 코드 변경 사항을 기본 분기에 통합하는 작업이 포함됩니다. 이렇게 하면 충돌을 조기에 식별하고 해결하는 데 도움이 되며 주 분기가 항상 최신 상태로 유지됩니다.

병합하기 전에 빌드하고 테스트하는 것도 트렁크 기반 개발의 중요한 개념입니다. 개발자는 변경 사항을 기본 분기에 병합하기 전에 성공적으로 빌드하고 테스트할 수 있는지 확인해야 합니다. 이렇게 하면 기본 분기가 안정적으로 유지되고 충돌이 최소화됩니다.

## 모범 사례

코드 검토는 트렁크 기반 개발에서 중요한 모범 사례입니다. 코드 검토는 코드 변경이 고품질이고 팀의 코딩 표준을 준수하는지 확인하는 데 도움이 됩니다. 코드 검토는 또한 잠재적인 문제와 충돌을 초기에 식별하는 데 도움이 되므로 기본 분기가 손상될 위험을 최소화하는 데 도움이 됩니다.

기능 플래그는 트렁크 기반 개발의 또 다른 모범 사례입니다. 기능 플래그를 사용하면 개발자가 일부 사용자에게 새 기능을 릴리스할 수 있으므로 기본 분기가 손상될 위험을 최소화할 수 있습니다. 또한 기능 플래그를 사용하면 개발자가 모든 사용자에게 릴리스하기 전에 프로덕션과 유사한 환경에서 새로운 기능을 테스트할 수 있습니다.

카나리아 릴리스는 트렁크 기반 개발의 또 다른 모범 사례입니다. Canary 릴리스에는 새로운 기능을 모든 사용자에게 릴리스하기 전에 일부 사용자에게만 새 기능을 릴리스하는 작업이 포함됩니다. 이는 문제를 조기에 식별하고 해결하는 데 도움이 되며 기본 분기가 안정적으로 유지되도록 합니다.

롤백 전략은 또한 트렁크 기반 개발에서 중요한 모범 사례입니다. 롤백 전략은 필요한 경우 기본 분기를 이전 상태로 롤백할 수 있도록 도와줍니다. 이렇게 하면 기본 분기가 손상될 위험을 최소화하고 팀이 발생하는 모든 문제에 신속하게 대응할 수 있습니다.

## 단점

트렁크 기반 개발의 주요 단점 중 하나는 기본 분기가 손상될 위험이 있다는 것입니다. 개발자가 변경 사항을 기본 분기에 직접 병합하기 때문에 변경으로 인해 기본 분기가 중단되고 모든 사용자에게 문제가 발생할 위험이 있습니다. 이러한 위험을 최소화하기 위해 개발자는 변경 사항을 주 분기에 병합하기 전에 철저히 테스트했는지 확인해야 합니다.

트렁크 기반 개발의 또 다른 단점은 빈번한 통신과 협업이 필요하다는 것입니다. 개발자는 변경 사항을 기본 분기에 직접 병합하므로 기본 분기가 안정적으로 유지되도록 서로 통신하고 효과적으로 협업하는 것이 중요합니다.

마지막으로 트렁크 기반 개발은 충돌 및 병합 문제로 이어질 수도 있습니다. 개발자가 변경 사항을 기본 분기에 직접 병합하기 때문에 두 개발자가 동일한 파일을 변경하면 충돌이 발생할 위험이 있습니다. 이러한 위험을 최소화하기 위해 개발자는 효과적으로 의사 소통하고 동일한 파일에 충돌하는 변경 사항을 적용하지 않도록 해야 합니다.

## 다른 개발 워크플로우와 비교

트렁크 기반 개발은 종종 기능 분기, Gitflow 및 지속적 전달과 같은 다른 개발 워크플로와 비교됩니다. 기능 분기에는 각 기능 또는 버그 수정에 대해 별도의 분기를 생성하는 작업이 포함되며, 이로 인해 충돌 및 병합 문제가 발생할 수 있습니다. Gitflow는 기능, 릴리스 및 핫픽스에 대해 별도의 분기를 만드는 것과 관련된 분기 모델입니다. 지속적인 제공에는 코드 변경 사항을 프로덕션에 가능한 한 자주 릴리스하는 작업이 포함됩니다. 트렁크 기반 개발은 더 간단하고 관리하기 쉽기 때문에 이러한 다른 워크플로보다 선호되는 경우가 많습니다.

## 결론

트렁크 기반 개발은 소규모의 빈번한 업데이트를 코어 트렁크 또는 메인 브랜치에 병합하는 것과 관련된 소프트웨어 개발 워크플로우입니다. 사이의 일반적인 관행입니다.
