Conan Repository — Exclusive

The feature, introduced in Conan 2.4.1, provides a powerful mechanism for distributing software while keeping internal dependencies and recipes completely private. When a package is created with the vendor attribute set to True , Conan does not download the recipes or binaries of its dependencies. Instead, all necessary binaries are embedded directly into the main package. This is particularly useful for:

Create a streamlined process for developers to request new open-source libraries. An automated CI pipeline can download the requested package from Conan Center, run vulnerability scans (using tools like JFrog Xray or Snyk), verify the license, and promote it to your exclusive remote repository. Smart Binary Management

Conan provides no global “exclusive mode” flag. Instead, exclusivity is achieved via:

: Ensuring proprietary packages are never exposed to public mirrors or cached incorrectly from external sources.

A Conan repository exclusive setup means your development environment is locked to one specific package server. By default, Conan can query multiple remotes sequentially (such as Conan Center and internal team servers) to resolve dependencies. conan repository exclusive

This is controlled by global.conf settings:

A single, aggregated endpoint that combines the local and remote repositories under one URL.

Feature Title: Conan Repository Exclusivity & Scoped Resolution 1. Overview

In an exclusive model, you disable all public external registries at the client level. Instead, you route all traffic through a single internal registry—typically managed via JFrog Artifactory or a private Conan server. This central hub acts as the exclusive gatekeeper for both your proprietary code and vetted open-source binaries. Why Enterprises Adopt Exclusive Repositories The feature, introduced in Conan 2

In enterprise software development, managing C and C++ dependencies requires absolute control over source code, binaries, and access permissions. As the de facto package manager for C/C++, Conan relies on repositories to store and retrieve these dependencies.

By using the vendor feature, you can share your software packages without exposing the recipes and binaries of your internal dependencies. This is crucial for maintaining the confidentiality of proprietary code and internal build processes.

Do your build agents have , or are they air-gapped?

Point your local Conan client to your new private remote instead of (or in addition to) ConanCenter. This is particularly useful for: Create a streamlined

# Ensure internal packages only come from the private enterprise remote $ conan remote add-pattern internal_private "mycompany_*" # Ensure standard open-source packages only come from ConanCenter $ conan remote add-pattern conancenter "zlib/*" $ conan remote add-pattern conancenter "openssl/*" Use code with caution. 2. Restricting the Global "Catch-All"

This figure perfectly encapsulates the appeal of a repository exclusive: a unique, highly themed version of a character that you simply can't find anywhere else.

This article explores the concept of exclusive Conan repositories, why they are necessary, and how to manage them effectively to improve security, reliability, and development speed. What is a "Conan Repository Exclusive"?

In this setup, developers and build servers are restricted from reaching out directly to public repositories like ConanCenter. Instead, any allowed public package must first be vetted and hosted within the organization's internal infrastructure. Why Adopt a Conan Repository Exclusive Strategy?
