Cloudsmith gives you a fully managed, cloud-native Alpine repository that scales with your team, supports native apk tooling, and gives you complete control over access and security. ## Create Your Private Alpine Repository Alpine Linux is a lightweight Linux distribution that is widely used in embedded systems, and as the basis for containers such as Docker. Cloudsmith is a fully managed, cloud-native solution that allows you to create your own private Alpine repositories. Universal format support ## **One platform for all your artifacts.** Cloudsmith is a secure, centralized store for Alpine packages, containers, and more. - Use Alpine + 30 other formats - Proxy and cache upstream Alpine Linux mirrors to protect builds from outages - Manage Alpine packages alongside Docker containers in a single repository ## How we support **Alpine** Cloudsmith gives you a fully managed Alpine repository with everything your team needs to push, pull, and secure APK packages using native tooling. ### Native APK compatibility Push and pull Alpine packages using standard apk tooling. Cloudsmith provides APK-compatible repository endpoints that work with your existing workflows without any additional configuration. ### RSA-signed repositories Every Cloudsmith Alpine repository is RSA-signed so clients can verify package authenticity via apk. Entitlement token and HTTP Basic authentication protect private repositories. ### Vulnerability scanning and policy enforcement Automatically scan Alpine packages for CVEs and apply OPA Rego policies to quarantine or block packages that violate your security standards before they reach your teams. ### Upstream proxying and caching Proxy and cache packages from Alpine Linux mirrors so your builds never fail due to upstream outages. Cloudsmith keeps a permanent local copy of every package your pipelines depend on. ### Multi-format repositories Store Alpine packages alongside Docker images, Debian packages, Python wheels, and 30 other formats in the same Cloudsmith repository. One platform, one bill, full control.

Cloudsmith fixes all of it. | Without Cloudsmith | With Cloudsmith | | --- | --- | | Upstream Alpine mirrors remove or replace package versions without warning, causing Docker builds to fail mid-pipeline when a specific version of a package disappears. | Cloudsmith caches every package version your pipelines pull, so builds always resolve the exact version they need, regardless of what happens upstream. | | Alpine's public repositories lack strict version retention, making it impossible to lock package versions reliably and guarantee identical, reproducible builds across environments. | Cloudsmith gives you a private repository with stable, immutable package storage. Your teams pin exact versions and reproduce builds consistently, every time. | | Self-hosted or ad-hoc Alpine repositories have no built-in security scanning, no policy enforcement, and no audit trail, leaving teams blind to CVEs in their APK dependencies. | Cloudsmith scans every Alpine package for vulnerabilities, enforces OPA Rego policies automatically, and produces a full audit log so your security team has complete visibility. | ## Signs you're ready to switch to Cloudsmith for **Alpine** If your current Alpine setup is blocking builds, creating security blind spots, or demanding constant maintenance, Cloudsmith is the upgrade. Here is what teams tell us pushes them to switch. ### Upstream package removal breaks your Docker builds Alpine's public mirrors prune old package versions regularly. If your Dockerfiles reference a specific version that disappears, your build fails. Cloudsmith caches upstream packages permanently so this never happens. ### No security scanning on your APK dependencies Running Alpine packages without vulnerability scanning is a supply chain risk. Cloudsmith automatically scans every package for CVEs and lets you define policies that quarantine or block risky packages before they reach production. ### Self-hosted infrastructure you don't want to manage Running your own Alpine mirror means patching servers, managing storage, and handling failover. Cloudsmith is fully managed: no servers to maintain, no downtime to babysit, and 99.9% uptime backed by a global CDN. ### Fragmented tooling across formats Teams using Alpine alongside Docker, Python, or Debian end up with multiple registries and tooling to manage. Cloudsmith consolidates all 30+ formats into one repository, one access model, and one audit trail. ### Access control that doesn't scale with your team Sharing Alpine packages with customers or partners using shared credentials is a security risk. Cloudsmith's entitlement token system gives each consumer a unique, revocable token with fine-grained permissions.

Yes. Cloudsmith provides APK-compatible repository endpoints so you can use standard apk commands to push and pull packages without any additional plugins or wrappers. Setup instructions with copy-paste snippets are available directly inside each repository. ### How does Cloudsmith handle authentication for private Alpine repositories? Private repositories support Entitlement Token Authentication and HTTP Basic Authentication. Entitlement tokens can be scoped, time-limited, and revoked individually, giving you fine-grained control over who can access each repository. ### Are Alpine repositories RSA-signed? Yes. Every Cloudsmith Alpine repository is signed with an RSA key. Clients verify package integrity via apk using the public key, ensuring packages have not been tampered with in transit. ### Can Cloudsmith proxy and cache upstream Alpine Linux mirrors? Yes. Cloudsmith supports upstream proxying and caching for Alpine Linux mirrors. Requested packages are fetched and permanently stored in your Cloudsmith repository, protecting your builds from upstream outages or version removal. ### Does Cloudsmith support Wolfi packages in the same repository? Alpine and Wolfi both use the APK format but are distinct, incompatible distributions. Cloudsmith automatically detects the distribution at upload time. You should use separate Cloudsmith repositories for Alpine and Wolfi packages to avoid conflicts. ### How does Cloudsmith help with reproducible Docker builds using Alpine? Cloudsmith caches specific package versions from upstream mirrors permanently. This means the exact version your Dockerfile requests is always available, eliminating the broken builds that occur when Alpine's public mirrors remove or replace package versions. ### What security scanning does Cloudsmith offer for Alpine packages? Cloudsmith automatically scans every uploaded Alpine package for known CVEs and malware. You can define OPA Rego policies to quarantine or block packages based on vulnerability severity, ensuring risky packages never reach your build pipelines. ### Can I store Alpine packages alongside other formats like Docker or Debian? Yes. All Cloudsmith repositories are multi-format, meaning Alpine packages can sit alongside Docker images, Debian packages, Python wheels, and 30+ other formats in the same repository with a single access model and unified audit trail. ### How do I migrate from a self-hosted Alpine mirror to Cloudsmith? You can upload existing APK packages to Cloudsmith via the CLI, REST API, or web app. Configure Cloudsmith as an upstream proxy for your existing mirrors to cache packages automatically, then update your /etc/apk/repositories entries to point at Cloudsmith. Your team's apk commands continue to work without modification. ### Which Alpine Linux versions does Cloudsmith support? Cloudsmith supports all Alpine Linux release branches. The distribution and codename are specified at upload time and automatically detected at install time. You can also force a specific distribution and codename using the setup script parameters provided in the Cloudsmith repository setup instructions.
