You have three primary options for hosting an exclusive Conan repository. Choosing the right one depends on your team size and budget.
You can designate a private repository as exclusive for all internal packages. This ensures that no malicious or outdated version accidentally slips in from a public remote. For regulated industries (automotive, medical, finance), exclusive repos are audit requirements.
As of Conan v2.0, the concept of repository exclusivity has been hardened. New features include: conan repository exclusive
Symptom: Package A (exclusive to private-repo) depends on package B, which is not exclusive. Conan fetches B from conan-center, but B then links to a different version of A.
Cause: Exclusivity is not automatically transitive unless you configure it recursively.
Fix: Use a lockfile or set default_policy = "missing" alongside exclusive remotes. Also, consider creating a graph lock that pushes exclusivity down the chain.
In the modern era of software development, package managers have become the backbone of efficient workflows. For Python, there is PyPI; for JavaScript, npm; for Rust, Cargo. For C and C++, the gold standard has increasingly become Conan, an open-source, decentralized package manager. You have three primary options for hosting an
However, while pulling public libraries from Conan Center is straightforward, the true power of Conan for teams and enterprises lies in a concept that doesn’t get enough attention: the Conan Repository Exclusive.
What exactly is a "repository exclusive"? It refers to the practice of hosting private, proprietary, or modified packages in a remote repository that is accessible only to you or your organization. By establishing a Conan repository exclusive to your team, you stop wrestling with system-wide dependencies and start treating C++ libraries with the same agility as modern web frameworks. This ensures that no malicious or outdated version
This article dives deep into why you need an exclusive repository, how to set one up, and the advanced workflows that will transform your C++ build pipeline.
In the context of Conan (the C/C++ package manager), the term "exclusive" typically refers to a configuration policy or a repository mode that restricts how packages are consumed or uploaded.
Specifically, this concept is most relevant when discussing Conan 2.0 Remotes or Conan Center Index policies regarding "exclusive" package hosting.
