Using Octo.exe

Last updated

Octo is the preferred method when packaging .NET Core applications or applications which generally don't use Visual Studio. Octo can also be used with full .NET framework applications if you require more flexibility than what OctoPack provides. There are other ways to create packages which do not involve our tooling such as using NuGet.exe together with a manifest file (.nuspec file).

Octo is our API command line tool that allows you to interact with your Octopus Deploy server using different commands, one of which is the pack command which can turn any ordinary folder into a NuGet or Zip package - plain and simple. The Octo Command Line page will show you how to get the API command line tool installed and ready to use. All examples on this page however, assume that you are using the portable version of octo installed as a global tool which makes it available through the dotnet cli.

In Octo version 3.3.8 we have expanded the functionality of the pack command to allow creating zip packages in addition to NuGet packages. Learn more.

Octo Basic Usage

At a minimum octo pack requires an id to be provided:

dotnet octo pack --id="MyPackage"

The above command will generate a package in the current working directory and provide a timestamp based version number such as 2018.6.26.190140.nupkg.

If you want to provide your own version, you can pass the --version parameter in the call to Octo

dotnet octo pack --id="MyPackage" --version="1.0.0"

You can also change the output directory and folder which will be packed with the --outFolder and --basePath parameters respectively.

dotnet octo pack --id="MyPackage" --version="1.0.0" --basePath="folder/to/pack" --outFolder="destination/folder/path"

Packaging a .NET Core application

The process for packaging a .NET core applications is pretty straightforward and can usually be achieved by publishing the application and then using octo pack on the resultant output folder for example:

dotnet publish ./OctoWeb.csproj --output ./dist
dotnet octo pack ./dist --id="OctoWeb" --version="1.0.0"

Dotnet Core Publish vs Octopack
dotnet publish performs a lot of the heavy lifting that Octopack used to provide and therefore removes much of the need for it in .NET Core.

Please refer to Microsoft's publish and packing documentation for more information.

Packaging a .NET Core Library

If you are using .NET Core for class libraries, we recommend using dotnet pack from Microsoft.

dotnet pack ./SomeLibrary.csproj --output ./dist
dotnet octo pack ./dist --id="SomeLibrary" --version="1.0.0"

Packaging a .NET Framework Web application

There are usually some extra steps required to get the resulting application built and deployable. Full framework web applications are a good example of this, where simply building the application will not give you the desired output. We still recommend Octopack for these cases. However, you may be able to achieve this using msbuild parameters such as:

msbuild ./OctoWeb.csproj /p:DeployDefaultTarget=WebPublish /p:DeployOnBuild=true /p:WebPublishMethod=FileSystem /p:SkipInvalidConfigurations=true /p:publishUrl=dist
dotnet octo pack ./dist --id="OctoWeb" --version="1.0.0-alpha0001"

Packaging Your Application From a Folder

If you have a build process which places all build outputs into a final destination folder (such as gulp, grunt or webpack), you can package it using octo as well. For example, let's assume you have defined an npm script which runs your build and places all associated content into the dist folder:

npm run build
dotnet octo pack ./dist --id="SomeApplication" --version="1.0.0"


The Octo.exe pack command provides a number of other useful parameters that can be used to customize the way your package gets created, such as including release notes.

You can get help with the pack command parameters by executing the pack command with --help switch

C:\> dotnet octo pack --help

The output will explain how to use the command and the different parameters that can be passed to the command

C:\> dotnet octo help pack
Octopus Deploy Command Line Tool, version 3.3.8+Branch.master.Sha.f8a34fc6097785d7d382ddfaa9a7f009f29bc5fb
