CLI

Demeter provides multiple ways to manage and interact with your projects. One of those is dmtrctl, a command-line utility that lets you interact with the Demeter platform from your local terminal.

Installation

You can use Homebrew to install the latest version of Demeter CLI in Mac (both x86 / ARM64)

brew install demeter-run/tap/dmtrctl

If everything worked correctly, you'll be able to run dmtrctl in your terminal.

Configuration

The CLI needs to know which project to use when executing a command. It also requires an API-Key as authentication method. We call this information the "context".

To configure a new context:

dmtrctl init

and follow the steps provided by the CLI to store the required values in the local configuration. Alternatively, required values can be retrieved from the Console (Web UI).

Command Hierarchy

The CLI is organized by a hierarchy of sub-commands. Each commands might also contains nested sub-commands. Each command provides quick usage instructions by using the --help flag (such as dmtrctl <SUBCOMMAND> --help)

Advanced Configuration

dmtrctl uses a configuration file located within the root dir of the installation to store the context information. The default location for Mac and Linux users is ~/.dmtr/config.toml but this can be changed by specifying a different root dir.

To know in which context to execute a command, dmtrctl uses decision steps in the following order:

if the --context option was specified, use this value
if DMTR_CONTEXT env variables was specified, use this value
if there's a default context defined in the configuration, use that value

The location of the root dir can be changed by using the --root-dir option or the DMTR_ROOT_DIR env var.
