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 an deployment.
When the solution is built, a new Calamari package is created in the built-packages directory.
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:
C:\Octopus\OctopusServer\OctopusServer.config
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
