FAQ

Short answers to common questions about Sleet, with links to the pages that explain more. For errors, see troubleshooting.

Do NuGet clients need Sleet?

No. A Sleet feed is a standard NuGet v3 feed, and dotnet, Visual Studio, and nuget.exe read it like any other package source. Only the machines that push packages need Sleet. See use a feed with NuGet.

What does a feed cost to run?

There's no server, so you pay only your storage provider or web host for storage, requests, and data transfer. Check your provider's pricing page for the rates.

Can I make a feed private?

Yes, but NuGet can't sign in to Azure Storage or Amazon S3 itself. Put a proxy or CDN that handles sign-in in front of the storage, or allow access only from your network. See private feeds, and private feed on AWS for a full example.

Can I use dotnet nuget push?

No. There's no server to take the upload. Use sleet push instead. For the same reason, dotnet nuget delete doesn't work, so use sleet delete.

Why does search return every package?

Search on a Sleet feed is a static file, so it can't filter by the search term. See search results. To get real search, set up an external search service.

Can I unlist or deprecate a package?

No. You can only delete a package, which removes it from the feed. See unlisting.

Does Sleet support snupkg files?

No. The symbol server reads .symbols.nupkg packages, and .pdb files inside normal packages.

Can several builds push at the same time?

Yes. Sleet locks the feed, so the pushes run one after the other. It's still better to run one publish job at a time. See concurrency.

Can clients restore during a push?

Yes. NuGet clients don't use the lock, and Sleet uploads package files before the files that list them. See what a push does.

How do I publish from CI?

See publish from CI for GitHub Actions, Azure Pipelines, and GitLab CI examples. You can define the feed with environment variables instead of a settings file.

Can I host several feeds in one container or bucket?

Yes. See multiple feeds.

Can I use a CDN or my own domain?

Yes. Set baseURI to the URL that clients use before the first push. See CDN and caching and private feeds.

Which S3-compatible services work?

Sleet can use services that support the Amazon S3 API, such as Cloudflare R2, MinIO, DigitalOcean Spaces, and Backblaze B2. The Sleet maintainers don't test them, so check the provider notes in S3-compatible storage.

How do I move a feed?

Download the packages from the old feed, and push them to the new one. See backup and migration. The same page covers moving packages from another NuGet server.

How do I keep a feed small?

Use package retention to delete old versions when you push new ones. See large feeds.

How do I update Sleet?

Run dotnet tool update -g sleet, and check the release notes for changes. A new version of Sleet works with your existing feed, unless the feed was made by a version older than 2.2.0. See upgrade older feeds.

Can I use Sleet from .NET code?

Yes. The SleetLib package has the same features as the CLI. See SleetLib.
