exo is the official command-line tool to access Exoscale’s services. It allows you to manage your infrastructure from an user friendly command-line with the benefits of a scriptable interface.


To get started download the archive corresponding to your operating system from the latest release on GitHub.


Debian / Ubuntu

  • Download cli_$VERSION_linux_amd64.deb
  • Run $ sudo dpkg -i cli_$VERSION_linux_amd64.deb

RedHat / CentOS

  • Download cli_$VERSION_linux_amd64.rpm
  • Run sudo rpm -i cli_$VERSION_linux_amd64.rpm

Other distributions

  • Download cli_$VERSION_linux_amd64.tar.gz
  • Expand it
  • Put the exo binary into your $PATH, e.g. /usr/local/bin/


You can run the cli as a Docker container with the following command

docker run -it exoscale/cli <command argument>


The docker builds are for amd64 architecture only. For arm or arm64 use the tar.gz release

Apple macOS

Install with Homebrew:

brew tap exoscale/tap
brew install exoscale-cli

Or alternatively:

  • Download and open cli_$VERSION_darwin_amd64.tar.gz
  • Copy the exo executable in a directory inside your $PATH

Microsoft Windows

The binary file works for both the traditional Command Prompt as well as the more modern PowerShell.

  • Download cli_%VERSION%_windows_amd64.zip
  • Open the command-line shell (cmd.exe) and type the following commands

    mkdir C:\exoscale
    setx path "%path%;C:\exoscale;"
  • Put all files from zip archive into C:\exoscale\


A configuration file holding your credentials is required. You can generate one via a guided prompt. The following parameters are requested:

  • API Key
  • Secret Key

If you don’t already have a key and the corresponding secret, you can generate one using the Exoscale Console. To do so, log in and navigate to:

/Exoscale Console > IAM

API keys and secrets


The CLI will guide you in the initial configuration.

$ exo config

Once saved, you can review your current configuration later by running the exo config show command.

Commands overview

You are now ready to use the CLI. Start by calling the raw exo --help command. This will give you a list of the possible commands and options.

Create a Compute instance

The exo compute instance command allows you to do basic CRUD operations on Compute instances. Run exo compute instance create to deploy an instance:

$ exo compute instance create example

│ Labels               │ n/a                                  │

The command automatially create an ssh key specifically for this instance. If you wished to use an SSH key of yours, you can refer to it by name via the --ssh-key <keyname> option.

Create a firewall rule to allow SSH connection

By default, security groups without any rule specified block all incoming connections. To reach your instance via SSH, you have to explicitly allow ingress on port 22. The exo compute security-group rule add command lets you do so:

$ exo compute security-group rule add default --network --port 22
 ✔ Adding rule to Security Group "default"... 3s
│  SECURITY GROUP  │                                                                    │

│ Egress Rules     │ -                                                                  │

Connect to a Compute instance via SSH

The exo compute instance ssh command allows you to directly log into an instance using an SSH connection.

$ exo compute instance ssh example
Host key fingerprint is SHA256:nmAfu17qHLkJkEpOy2qXWaV5nSMq0yzKD6j0giZIghk
Welcome to Ubuntu 19.04 LTS (GNU/Linux 4.15.0-20-generic x86_64)


Cleaning up

Removing an instance is as simple as creating one. Be cautious as there are no ways to undo a deletion.

$ exo compute instance delete example
[+] Are you sure you want to delete instance "example"? [yN]: y
 ✔ Deleting instance "example"... 6s

Alternative output formats

By default, commands outputting information as a result of an operation format the content in a table, a format convenient for human consumption. In case you’re use the exo CLI in scripts, you might find alternative output formats JSON or templated text to be more suited for non-interactive uses:

$ exo compute instance show example -O json | jq -r .ip_address

# Text templating
$ exo compute instance show example -O text --output-template '{{.ID}}@{{.Zone}}'

More information on this topic can be found by running the exo help output command.
