Supported Formats

Last updated

Octopus Deploy supports several package types that can be used when packaging your applications and will continue to add more in the future.

Octopus uses the file extension to determine the correct extraction algorithm to use, so it is important that your package has the correct extension for the package format.

Package Type File Extensions Notes
NuGet .nupkg Any NuGet repository (including the Built-In repository) Currently only NuGet packages will have extra metadata like release notes and description extracted from the package metadata.

Pre-Release packages and Multipart file extensions

If you're planning to use a multi-part file extension (e.g. .tar.gz) with a pre-release naming convention (MyApp.1.0.0-beta.tar.gz) and use the Run on Server steps option, this will result in an error message of Unsupported file extension .gz. This is because the .tar forms part of pre-release tag and not part of the file extension.

The error only occurs on Run on Server steps and deployments execute on as expected on Tentacles.
