What is the difference between Bitbucket and Docker?

Comparing Bitbucket to Docker is like comparing a filing cabinet to a shipping container—they serve very different purposes in the development process. Bitbucket is a version control system built on Git, while Docker is a containerization platform used to package applications and their environments.

Bitbucket allows teams to:

• Store and manage source code in Git repositories

• Track changes, collaborate with pull requests and inline comments

• Set up continuous integration (CI) pipelines using Bitbucket Pipelines

• Control access with branch permissions and role-based controls

It’s especially useful for teams using Atlassian tools like Jira and Trello, as it integrates seamlessly with these platforms.

Docker, on the other hand, is about runtime environments and deployment. Developers use Docker to:

• Build application images that include code, libraries, and OS-level dependencies

• Run those images in isolated containers across different machines

• Ensure consistency between dev, test, and production environments

• Manage complex microservice architectures

So while Bitbucket helps manage code throughout its lifecycle, Docker helps you deploy and run that code in efficient, scalable containers.
