fugue [global options] install [options]


Global options are detailed here.

-y | --yes
Suppress confirmation dialogs. The yes flag suppresses confirmation dialogs and bypasses interactive prompts by providing input to aid scripting.
-h | --help
Show help text. The help flag is available throughout the CLI in both an application-level and command-level context. It enables a user to view help text for any command within the Fugue CLI.


The install command installs the Fugue Conductor in the user’s AWS account and boots Fugue.

First, the Fugue CLI determines the target AWS account by searching for credentials in the following order:

  • The environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY; then,
  • The profile in ~/.aws/credentials or ~/.aws/config that matches the credentialProfile field in fugue.yaml; then finally,
  • The instance metadata service (IMDS), which is present only on EC2 instances and provides credentials reflecting the IAM Role of the instance.

The CLI tests the validity of the credentials and, in so doing, determines the account number and alias that they are associated with. This is the account that the install command targets.

Next, the CLI asks the user to confirm they want to install Fugue into the target AWS account with the AMI ID defined in fugue.yaml:

[ fugue install ] Installing Fugue Conductor

Install Details:

   Conductor AMI ID: ami-e0364df7
   AWS Account: <user>/xxxxxxxxxxxx
   Region: us-east-1

[ WARN ] Would you like to proceed with installing? [y/N]:

When the user enters y, the Fugue CLI launches a CloudFormation stack inside that AWS account using the specified AMI. As the required resources are created, the CLI displays a table showing installation progress.

Installing the Fugue Conductor into AWS account user/xxxxxxxxxxxx.

[ HELP ] Exiting the install command while in progress (CTRL+C) will only stop progress tracking and *not* the install itself.

Note: While the CLI currently indicates that (CTRL+C) will not stop the installation, we do not recommend using this command as it may interrupt the successful creation of credentials. In the event (CTRL+C) is used you can manually create your credentials using fugue support reset-secret. These recommendations will be updated in a future release.

When the installation is complete, the CLI creates default user credentials in a credentials file. These are your root credentials, so don’t lose them!

Creating default user credentials ...

User Credential Details:

user = root

Next, the CLI deletes the fugue.yaml.old file if it exists, renames the current fugue.yaml file to fugue.yaml.old, and creates a new fugue.yaml.

Found existing fugue.yaml.old file in /Users/user/projects .
Deleting existing fugue.yaml.old ...
[ OK ] Existing fugue.yaml.old file deleted.

Found existing fugue.yaml file in /Users/user/projects .
Renaming existing fugue.yaml file to fugue.yaml.old ...
[ OK ] Existing fugue.yaml file renamed.
[ OK ] Fugue Conductor installed.

The CLI creates a Fugue user IAM role and a Fugue installer IAM role, and then it displays the role names.

Fugue IAM Role Details:

   Installer: fugue-installer-us-east-1
   User: fugue-user-us-east-1

Then, the CLI asks the user to wait while the Conductor boots up.

[ OK ] Fugue Conductor installed.

Booting the Conductor, please wait as this may take between 5-15 minutes...

[ HELP ] The Conductor needs to boot before it can accept commands from the CLI. Exiting the install command while in progress (CTRL+C) will only stop progress tracking and *not* the install itself or the booting process.

When booting is complete, the CLI states that Fugue is ready to receive commands again.

[ DONE ] Fugue has been successfully installed and is ready to receive commands.


When the Conductor is uninstalled, the RBAC policy is removed along with all users and their credentials. If you reinstall the Conductor with install, you’ll need to apply the policy again with policy rbac-attach, and root will have a new user secret.

Using status to confirm the Fugue Conductor is done booting

In general, it is not recommended to use CTRL+C to halt the installation process as this can prevent the creation of your credentials. However, if you exit the install command with CTRL+C while the Conductor is still installing or booting, you may run fugue status to determine whether the Conductor is ready to receive commands. If the Conductor hasn’t finished installing or booting, status returns an error message:

[ ERROR ] There was a problem executing this command.
   Reason: The Conductor is in the process of installing.

In addition, you may be forced to manually create your credentials using fugue support reset-secret. However, if the Conductor is ready to receive commands, status returns this message:

Fugue Status Report for <user>/<account> - Fri Mar 17 2017 5:31pm

State    Updated    Created    Account    FID    Alias    Flags    Last Message    Next Command
-------  ---------  ---------  ---------  -----  -------  -------  --------------  --------------
Nothing to see here. Go create something! :-)

Changing The Region The Conductor Is Running In

While we anticipate changing this in the future, at present Fugue only supports running Conductors in us-east-1, us-east-2, us-west-2, eu-west-1, and us-gov-west-1. To specify a region for the Conductor use init and provide the the desired region.

Changing The Size Of The Conductor Instance

The Conductor instance type is m4.large by default. Currently, we do not support changing the size of the Conductor instance. If you believe you need a different size, email

Manually Setting Installation Availability Zones

If you have problems installing Fugue due to an Availability Zone (AZ) being unavailable for new resources in your account, or wish to customize the AZs used by Fugue for installation, you can manually specify the AZs that Fugue uses for the Fugue Conductor installation in your fugue.yaml. These AZs will be used when you run the fugue install command. To do this, add an entry in fugue.yaml under the conductor heading called installAZ as a list of two known-good availability zones in your account. For example:

    - us-east-1c
    - us-east-1d

Next time you run fugue install, the command will install the Fugue Conductor VPC with subnets in the first two AZs listed.

There are two caveats you should keep in mind if you have to use this feature. Firstly, bear in mind that you can specify one or two AZs. If you specify one, the CLI will log a warning during installation, but Fugue will install and run. If you specify two, installation should proceed as normal. If you specify more than two, only the first two will be used, and all subsequent entries in the list will be ignored.

Secondly, the AZs you list will be assumed valid. If you provide an invalid or unavailable AZ for your account, installation will fail with a CloudFormation stack error, like:

[ ERROR ] AWS CloudFormation stack creation failed

Note that you can get a list of AZs available to you using the AWS CLI command describe-availability-zones, but this is the same command that Fugue uses, and it sometimes returns unreliable data. As a rule of thumb, you should look for a pair of AZs that are listed as available to you, but that you don’t heavily utilize.

Changing the System Vars DDB Table Prior to Installation


Changing your Vars table can have severe consequences, including dropping your entire dataset. Do not change your Vars table unless you have been instructed to do so by Fugue Support.

The default DynamoDB table that Vars uses for key/value storage is fugue-vars-headless-store. This is where Fugue stores internal data related to running the Conductor. To use a different table, you can specify the new table name in fugue.yaml prior to installing or upgrading Fugue. Note: The new table name must begin with fugue-vars-.


When pointing Vars to a new table, there is no automatic data migration. This means that a newly booted Conductor will act like a fresh install, and any existing infrastructure will no longer be enforced, cleaned up, or even seen by the Conductor.

To change the table name prior to executing install, first edit fugue.yaml to add the experimental block, including the desired name of the DynamoDB table. Your fugue.yaml may look like this (minus the user block):

 ami: ami-491bbb5f
 region: us-east-1
 varsSystemTable: fugue-vars-headless-store-v2

Second, turn on the FUGUE_CLI_PREVIEW flag. This flag is required for enabling experimental configuration.


Finally, execute install:

fugue install

Fugue will create the new DynamoDB table for Vars as part of the Conductor installation process.
