Linux servers can be configured as deployment targets in Octopus.
The Octopus Server can communicate with Linux targets in two ways:
- Using the Linux Tentacle.
- Over SSH using an SSH target.
When using SSH for deployments to a Linux server, the Tentacle agent is not required and doesn’t need to be installed.
The Linux Tentacle is the recommended way to configure your server as a deployment target. This allows you to secure the SSH port on your servers.
If you operate in a highly secure environment, where it’s not possible to open an inbound TCP port for Tentacle (10933 by default), you can configure the Linux Tentacle in Polling mode.
Dependencies
- The
$HOMEenvironment variable must be available. bash3+ is available at/bin/bashtaris available. This is used to unpack Calamari.base64is available. This is used for encoding and decoding variables.grepis available.
There are additional dependency requirements to be aware of for both SSH targets and Linux Tentacle.
These dependencies are not required if exclusively utilizing Raw Scripts.
Supported distributions
Since tooling used to invoke Octopus workloads is based on .NET 6, Octopus Server supports running workloads on the following distributions as per the .NET 6 supported platform details.
| OS | Versions |
|---|---|
| CentOS Stream | 9 |
| Debian | 12, 11 |
| Fedora | 40, 39 |
| openSUSE Leap | 15.6, 15.5 |
| Red Hat Enterprise Linux | 9, 8 |
| SUSE Enterprise Linux | 15.6, 15.5, 12.5 |
| Ubuntu | 24.04, 22.04, 20.04 |
Although the tooling requires the platform to support .NET Core, since it runs as a self-contained .NET deployment there is no .NET installation prerequisite.
In addition to the .NET 6 requirement, Octopus will only support those Operating Systems which are themselves still considered as supported by the platform vendors themselves.
