OctopusDeploy Calamari Save

| Public | The core deployment scripts and tools used by Octopus Deploy

Project README

Calamari is the command-line tool invoked by Tentacle during a deployment. It knows how to extract and install NuGet packages, run the Deploy.ps1 etc. conventions, modify configuration files, and all the other things that happen during a deployment.


You will need the .NET SDK 5.0, downloadable from https://dotnet.microsoft.com/download

Run Build-Local.ps1 or Build-Local.sh to build the solution locally.

When the solution is built, several new Calamari nuget packages are created in the artifacts directory.

For Octopus Developers:

The Build-Local scripts will also copy the nuget packages to the LocalPackages folder which can be found in the same parent folder as the Calamari repo. If the Octopus Server repo exists in the same parent folder, Build-Local will also update the Octopus.Server.csproj to reference the Calamari version produced by the build. This means that you can simply rebuild Server locally to test the new version of Calamari.

folder structure example:



Octopus Server 2020.3+: Using a custom version of Calamari may not work

Calamari is currently being filleted into Sashimi. Due to the architectural changes involved in this transformation, using a custom version of Calamari with Octopus Server version 2020.3+ may not work. Please get in touch with [email protected] if this affects you, to help us make decisions about how we can support custom implementations of deployment steps.

To use your own Calamari package with an Octopus 3.0 server, run the following commands

Octopus.Server.exe service --instance <instance> --stop --nologo --console
Octopus.Server.exe configure --instance <instance> --customBundledPackageDirectory=<directory> --nologo --console
Octopus.Server.exe service --instance <instance> --start --nologo --console

where <directory> is the directory containing the Calamari.*.nupkg files. If your server is setup as the default instance, you may ommit the --instance <instance> parameter.

This will add the following setting to your Octopus Server configuration file:

  <set key="Octopus.Deployment.CustomBundledPackageDirectory">C:\GitHub\Calamari\built-packages</set>

The exe and configuration file can normally be found at:


If you want to revert to the bundled package, run the following commands

Octopus.Server.exe service --instance <instance> --stop --nologo --console
Octopus.Server.exe configure --instance <instance> --customBundledPackageDirectory= --nologo --console
Octopus.Server.exe service --instance <instance> --start --nologo --console

** Ensure you update your build to the latest Calamari or revert to the bundled package when you upgrade Octopus Server **


After you finish merging to master to tag the Calamari NuGet package:

Firstly, find out what the latest tag is. There are two ways to do this:

  • On your terminal, checkout master and git pull for good measure
  • Run git tag and scroll to the bottom of the list to get the last known tag


  • Check the last build on master as it will be pre-release version of the next <Major>.<Minor>.<Patch> version

Finally, tag and push the new release

  • Patch, Minor or Major Version the tag according to <Major>.<Minor>.<Patch>
  • git push origin <Major>.<Minor>.<Patch> to push your newly created tag to Github.

[!WARNING] Avoid using git push --tags as it will push all of your local tags to the remote repository.
This is not recommended as it can cause confusion and potential issues with the build server when it attempts to calculate the release version number due to the potential of unexpected tags being pushed.

This will trigger our build server to build and publish a new version to feedz.io which can be seen here https://feedz.io/org/octopus-deploy/repository/dependencies/packages/Calamari.


Option 1 is recommended if you can use the default worker.

Option 1: Reference local binary

  1. Build Calamari in your IDE
  2. Get the path to the executable (The one directly in the bin folder for the Calamari project for the flavour you want to debug e.g. Calamari or Calamari.AzureAppService with no extension for macOS and Linux, Calamari.exe or Calamari.AzureAppService.exe for Windows)
  3. In Octopus, set an unscoped variable Octopus.Calamari.Executable to the full path to the executable. This is set per project.
  4. Now when you run a deployment it will use your debug build.


  • Extremely fast iteration, you don’t need to stop server between Calamari builds.
  • It does not exercise the full deployment functionality of checking calamari versions etc (most of the time, this does not matter).


  • You must run the step on your machine (default worker) - basically the executable has to be at the path on whatever machine is executing the step. This is a problem when working with Kubernetes Tentacle for example.

Option 2: Package Calamari into your server build

  1. In terminal, run ./build-local.sh (build-local.ps1 is available for Windows)
  2. Nuke will build and package up Calamari then it will update the Calamari.Consolidated version in your Octopus.Server.csproj
  3. Restart Server to force a rebuild with the new version of Calamari.

Note: You must have a local nuget feed setup for the path ../LocalPackages relative to this repo

eg. dotnet nuget add source -n local ~/path/to/LocalPackages


  • It uses the “proper” mechanism to deploy Calamari.
  • You can use it when you’re using a remote worker.


  • It takes ~10 minutes to build and pack Calamari, however you can reduce this significantly by targeting a specific runtime/framework if you don't need the rest
    • eg ./build-local.sh -y --framework "net6.0" --runtime "linux-x64"
  • You need to restart Server for Calamari changes to take effect

Bonus Variables!

  • Set Octopus.Calamari.WaitForDebugger to True to get a debug version of Calamari to wait for a Debugger to be attached before continuing. The log message from Calamari will show it’s waiting for the debugger and it will give the PID to use when you’re looking to attach.
  • Set OctopusPrintEvaluatedVariables to True to get all variables that are sent to Calamari, printed to the verbose long when executing a step.

Tip: Creating a variable set with your configuration makes it easy to toggle this behaviour per project
