}

The packages in a release are available as a collection which can be iterated over. e.g.

#{each package in Octopus.Release.Package}
    This release contains #{package.PackageId} #{package.Version}
#{/each}

A particular package can be selected by indexing on the package ID:

#{Octopus.Release.Package[Acme.Web].Version}

The variables available for packages are:

On each package, the commits associated with that package are available as a collection which can be iterated over. e.g.:

#{each package in Octopus.Release.Package}
#{each commit in package.Commits}
- [#{commit.CommitId}](#{commit.LinkUrl}) - #{commit.Comment}
#{/each}
#{/each}

A particular commit can be selected by indexing on the commit ID (when using git the commit ID is the commit hash):

package.Commits[685afd4161d085e6e5f56a66e72e2298e402b114].Comment

The variables available for commits are:

If the Octopus instance has one or more of the Issue Tracker integrations enabled, the commit messages will be parsed for issues. Any issues found will be displayed with the build information, and also available as variables:

#{each issue in package.WorkItems}
- [#{issue.Id}](#{issue.LinkUrl})
#{/each}

A particular issue can be selected by indexing on the ID:

If the step failed because of an error, a description of the error.

Example: The server could not be contacted

Octopus.Step.Status.ErrorDetail

If the step failed because of an error, a full description of the error.

Example: System.Net.SocketException: The server could not be contacted (at …)

Agent

Agent-level variables describe the deployment agent or Tentacle on which the deployment is executing.

Octopus.Tentacle.Agent.ApplicationDirectoryPath

The directory under which the agent installs packages.

Example: C:\Octopus\Tentacle\Apps

Octopus.Tentacle.Agent.InstanceName

The instance name that the agent runs under.

Example: Tentacle

Octopus.Tentacle.Agent.ProgramDirectoryPath

The directory containing the agent’s own executables.

Example: C:\Program Files\Octopus Deploy\Tentacle

Octopus.Agent.ProgramDirectoryPath

The directory containing either the server or Tentacle’s executables depending on which the step being executed on.

Example: C:\Program Files\Octopus Deploy\Octopus

Worker Pool

When a step is run on a worker, the following variables are available:

Octopus.WorkerPool.Id

The Id of the pool.

Example: WorkerPools-1

Octopus.WorkerPool.Name

The name of the pool.

Example: Default Worker Pool

Server

Server-level variables describe the Octopus Server on which the deployment is running.

Octopus.Web.BaseUrl

The default URL at which the server API can be accessed. Note that this is based off the server’s ListenPrefixes and works in simple configuration scenarios. If you have a load balancer or reverse proxy this value will likely not be suitable for use in referring to the server from a client perspective, e.g. in email templates etc.

Example: https://my-octopus

Octopus.Web.ServerUri

The default URL at which the server portal can be accessed, as configured in the Configuration ➜ Nodes settings. This variable was added in Octopus 2019.4.0.

https://my-octopus

Tracking deployment status

During deployment, Octopus provides variables describing the status of each step.

Where S is the step name, Octopus will set:

Octopus.Step[S].Status.Code
Octopus.Step[S].Status.Error
Octopus.Step[S].Status.ErrorDetail

Status codes include Pending, Skipped, Abandoned, canceled, Running, Succeeded and Failed.

For an action A:

Octopus.Action[A].IsSkipped

For the deployment as a whole:

Octopus.Deployment.Error
Octopus.Deployment.ErrorDetail

Example: /app/runs/runbookRuns-123

User-modifiable settings

The following variables can be defined as variables in your project to modify the way Octopus behaves.

Octopus.Acquire.MaxParallelism

Maximum number of NuGet packages that should be downloaded at once when acquiring packages.

Example: 3

Octopus.Action.MaxParallelism

The maximum number of deployment targets on which the action will concurrently execute, and the maximum number of steps which will run in parallel. This value can be set in a project variable to change the default for the project. Additionally you can scope a value to specific actions to control concurrency across your deployment targets. This is the same variable which is set when configuring a rolling deployment. (Number - Default: 10).

Example: 5

OctopusPrintVariables

Set to “True” to tell Tentacle to print the value of all variables passed to it. We recommend only using this setting for non-production environments.

Example: True

OctopusPrintEvaluatedVariables

Set to “True” to tell Tentacle to print the value of all variables passed to it after evaluating them. We recommend only using this setting for non-production environments.

Example: True

OctopusSkipFreeDiskSpaceCheck

Set to “True” to skip the check for available free disk space when deploying packages. Introduced in Calamari version 3.1.30..

Example: True

OctopusFreeDiskSpaceOverrideInMegaBytes

The amount (in megabytes) of available free disk space we should check for (overriding the default 500MB), failing the deployment if not enough free disk space is available. Introduced in Calamari version 3.1.30.

Example: 100

Octopus.Action.PowerShell.CustomPowerShellVersion

If specified, Windows PowerShell scripts will be invoked using PowerShell.exe -version {Version} where {Version} is the value you specified. Accepted values are 2.0, 3.0, 4.0, 5.0.
PowerShell Core scripts will be invoked using the installed version of PowerShell core which matches the specified value. The value must match one of the directories contained within %PROGRAMFILES%\PowerShell. Example values include 6 and 7-preview.
Introduced in Calamari version 3.3.13..

Example: 2.0

OctopusDeleteScriptsOnCleanup

For packaged scripts, set to “False” to keep the PreDeploy/Deploy/PostDeploy scripts in the target directory (i.e. don’t cleanup).

Example: False

Octopus.Action.Script.SuppressEnvironmentLogging

To suppress/disable the environment logging that occurs from script (eg. PowerShell or Bash Script Environment Variables logging). This only suppresses script logging and does not suppress the Octopus or Calamari environment logging. Introduced in Calamari version 3.6.5..

Example: True

Octopus.Action.PowerShell.ExecuteWithoutProfile

Set to true to not run the Tentacle service account’s PowerShell profile script when running PowerShell script steps (available in version 3.3.21+).

Example: True

OctopusSuppressDuplicateVariableWarning

Set to true to have the duplicate variable message logged as verbose instead of warning. Do this if you are aware of the duplication and that it isn’t causing any issues in your deployment (available in version 3.17.0+).

Example: True

Octopus.Action.Package.RunScripts

Set to false to prevent scripts inside packages from executing. Do this if you are aware of the duplication and that it isn’t causing any issues in your deployment (available in version 4.1.10+).

Example: True

Octopus.Calamari.CopyWorkingDirectoryIncludingKeyTo

Set to a file-path and the Calamari working directory will be copied to the configured location. Copied files include the one-time key to decrypt sensitive variables More details..

Example: c:\temp\octopus-debug

Octopus.Deployment.WorkerLeaseCap

This is an opt-in variable to help distribute multiple steps referencing the same package (including container) across a worker pool. By setting this, a worker will be reused for steps up to the cap, after which another worker will be selected and reused in the same way. If all workers have reached the cap, additional steps will be spread out evenly. By default this behaviour is disabled, and the same worker will be reused for all steps referencing the same package. Opt in by setting the variable to a number higher than 0.

Example: 1 - achieves a similar effect to round robin.
Example: 5 - a balance between reducing package transfer and distributing load.

Note: This value applies to both deployment processes and runbooks, as long as it’s scoped to the particular scenario.

Octopus.Task.ConcurrencyTag

Octopus will run one task at a time for a given concurrency tag. Set the variable to run tasks in parallel instead of serial or in serial instead of parallel. For example, tenanted deployments run in parallel by default. Removing tenants from the concurrency tag will run them serially: #{Octopus.Project.Id}/#{Octopus.Environment.Id}

Example: #{Octopus.Deployment.Tenant.Id}/#{Octopus.Project.Id}/#{Octopus.Environment.Id}
