Problem to solve

GitLab aims to enhance its package registry by implementing support for the Conda package manager in the Free tier. This will provide value to developers and platform engineers who rely on Conda to manage complex Python environments and dependencies.

Value Proposition

1. For Developers:
   • Simplified dependency management: Conda allows for easier handling of complex dependencies, including non-Python libraries.
   • Consistent environments: Conda ensures reproducible development environments across different platforms.
   • Improved package isolation: Conda's environment management reduces conflicts between projects.
2. For Platform Engineers:
   • Streamlined CI/CD integration: Native Conda support in GitLab allows for easier pipeline configuration.
   • Enhanced control over dependencies: Conda's environment files provide better visibility and management of project dependencies.
   • Cross-language support: Conda packages can include non-Python dependencies, simplifying deployment of complex applications.

Conda vs. PyPI?

While PyPI is widely used for Python packages, Conda offers several advantages:

1. Multi-language support: Conda can manage packages for multiple programming languages, not just Python.
2. Non-Python dependencies: Conda can manage system-level libraries and tools, which is crucial for data science and scientific computing workflows.

Proposal

Implement a Minimum Viable Product (MVP) for Conda package support in GitLab Package Registry, available in the Free tier.

MVP Features

1. Authentication system for Conda package manager
2. Endpoints for upload/publish, install/download, and package removal
3. Basic metadata handling and storage
4. Integration with GitLab CI/CD for package management

Success Criteria

1. Developers can authenticate with the Conda package manager through GitLab
2. Conda packages can be uploaded, downloaded, and removed via GitLab
3. Basic integration with GitLab CI/CD for package management is functional
4. The feature is available and fully operational in the Free tier

Documentation

Provide comprehensive documentation on how to use the Conda repository within GitLab, including:

• Setting up authentication
• Publishing packages
• Installing packages
• Integrating with CI/CD pipelines

Testing

• Develop a test suite covering basic Conda package functionality
• Ensure compatibility with popular Conda clients and tools
• Test integration with GitLab CI/CD pipelines

Rationale

Implementing Conda support in the Free tier will:

1. Enhance GitLab's appeal to developers and platform engineers working with data science, scientific computing, and complex Python projects
2. Provide a more comprehensive solution for Python dependency management compared to PyPI-only support
3. Streamline workflows for teams using Conda environments
4. Potentially attract new users from the data science and scientific computing communities
5. Offer a competitive advantage over other CI/CD platforms that lack native Conda support

By focusing on this Conda Repository MVC in the Free tier, GitLab can address the needs of a growing segment of developers and platform engineers who rely on Conda for their projects, while also differentiating itself from competitors.
