The Scale CLI is a command line interface for interacting with the Scale API and for working with Scale Functions locally. It facilitates interfacing with the Scale Registry as well as building, running, and interacting with Scale Functions locally.

The CLI is written in Golang and is Open Source.

Install the Scale CLI

The Scale CLI is the primary tool for interacting with Scale Functions and the Scale Registry. It can be easily installed using the following command:

curl -fsSL | sh

The CLI attempts to install itself to /usr/local/bin by default, but you can also specify a different directory by setting the INSTALL environment variable like so:

curl -fsSL | INSTALL=./ sh

To verify that the CLI was installed correctly, you can run the following command:

scale version

Building from Source

To build the CLI from source, you will need to have Go installed. Then, you can clone the source code:

git clone
cd scale-cli

The minimum supported version of Go for building the Scale CLI is 1.20.

Building the CLI can be done with the following command:

cd cmd
go build -o scale .

This will create a binary called scale in the cmd directory. You can then move this binary to a directory in your PATH to use it.

Using the Scale CLI

Once you have the Scale CLI installed, you can use it to interact with the Scale API and to build, run, and interact with Scale Functions locally.
