Comprehensive automation can be quickly developed by using the RCTL Command Line Interface (RCTL) utility. RCTL enables users to script and automate reproducible workflows without having to interact with the Controller via the Web Console or the APIs or the Terraform provider.
The RCTL CLI can be embedded into your preferred "workflow automation platform" and be used to perform operations on ALL resources managed by the Controller.
RCTL can be embedded into any kind of workflow automation or CI platform such as Jenkins, CircleCI, GitHub Actions, GitLab etc. Review the CI Integrations Section for additional details and examples on how to embed RCTL into your preferred CI platform.
Working examples of integrations are available on a public Github repository.
RCTL is supported on Windows, Mac, and Linux operating systems.
Users can use the same macOS binary on ARM based Macs by enabling Rosetta 2.
The Web console provides several conveniences for end users (developers etc) by making it intuitive for them to download the RCTL binaries.
- On the left panel of the admin console, click on "My Tools".
- Click on the "Download CLI" button and download the package for your operating system
- Unzip the downloaded package into a folder (for example: “rctl”).
Workflow automation systems and pipelines can embed the "download URLs" for RCTL binaries. Note that this download URL will always provide the "latest version" of the RCTL CLI.
Use the following steps to check the version of RCTL. Users are encouraged to upgrade to the latest versions on a periodic basis (esp. with every release) to ensure they can leverage the latest functionality.
- Open Terminal (on macOS or Linux) or Command Prompt (on Windows).
- Navigate (i.e. change directory) to the folder where RCTL was unzipped.
- Type the following command.
./rctl version VERSION: r1.21.0 BUILD: refs/tags/r1.21.0-43 BUILD-TIME: Fri 09 Dec 2022 11:02:14 AM UTC ARCH: darwin/amd64
RCTL can provide contextual help when requested.
You should see output similar to the example shown below.

The RCTL CLI can be used in both Interactive and Scripted modes.
This is the default mode and is primarily meant for human users that wish to view the results in a human-readable format.
This mode is useful when RCTL is embedded into a workflow such as an automation pipeline. The generated output will ideally be in a JSON or YAML format that can be consumed programmatically by the automation platform.
The RCTL CLI returns an exit code (aka return code) for every command. The standard exit code is "0" for SUCCESS. Any other number for an exit code should be considered an ERROR.
To get the exit code, type "echo $?" at the command prompt after the command completes. Customers can use these exit codes to check for status of a CLI command when it is embedded into a workflow/pipeline.
#!/bin/bash ./rctl version if [ $? -eq 0 ] then echo "The command ran OK" exit 0 else echo "The command failed" exit 1 fi
RCTL can be configured to print detailed information via "verbose mode" to assist with troubleshooting. During a support call, support may request you to use the "debug" mode to assist with debugging.
For example, to enable "verbose" mode while retrieving the list of workloads
./rctl get workload --verbose
For example, to enable "debug" mode while retrieving the list of workloads
./rctl get workload --debug
RCTL can generate auto completion scripts for your target platform and shell.
./rctl completion -h
On Linux or macOS, you can use the following command to identify the current shell. In the example below, the current shell is "bash".
echo $SHELL /bin/bash
