Amazon EC2


This connector is distributed by SixSq under a commercial license and is available via various pricing plans. You can check it out with a free trail via our SaaS service. Feel free to contact the SlipStream Support team with any questions about how the SlipStream Amazon EC2 connector can be beneficial to you and your business.

Once you have purchased a new commercial connector, SixSq will provide you with a specific yum configuration.


Once your yum configuration is in place, you can install the connector executing the following command:

$ yum install slipstream-connector-ec2-enterprise

With the software installed, you need to restart the SlipStream service in order for it to take the new connector into account:

$ systemctl restart slipstream

Now we need to configure SlipStream to take advantage of the new connector.


To allow users to take advantage of this connector, you must add one or more instances of this connector by either:

  1. Using the UI.
  2. Drop a configuration file and restart the service.

With the UI

Instanciate one or more instances of the connector

Once logged-in with a privileged user (e.g. super), open the configuration page by clicking on Configuration -> System at the top of the page. Then open the SlipStream Basics section and define a new instance of the connector with the following format:


Here is an example:


You can also instantiate the connector several times (in compliance with your license) by comma separating the connector string. Here is an example:

ec2-eu-central-1:ec2, ec2-eu-west-1:ec2, ...

Here is a screenshot of the parameter to define:

Don’t forget to save the configuration!

Now that the connector is loaded, you need to configure it.

Configure the connector instance

With the connector loaded in SlipStream, a new section in the configuration page will appear, allowing you to configure how the connector is to communicate with the IaaS cloud endpoint.

You can find a detailed description of each parameter as well as an explaination of how to find the right value of them in the `Parameters <#parameters>`__ paragraph below.

With a Configuration File

Please see Configuration Files for details about this method of configuration.

Here is an example, which will configure the EC2 connector to interact with the region eu-central-1:

> cat /etc/slipstream/connectors/ec2-eu-central-1.conf
cloud.connector.class = ec2-eu-central-1:ec2 = default
ec2-eu-central-1.update.clienturl = https://<slipstream-ip>/downloads/ec2client.tgz
ec2-eu-central-1.orchestrator.instance.type = t2.micro
ec2-eu-central-1.region = eu-central-1
ec2-eu-central-1.quota.vm =
ec2-eu-central-1.max.iaas.workers = 20
ec2-eu-central-1.orchestrator.imageid = ami-accff2b1

You can find a detailed description of each parameter as well as an explaination of how to find the right value of them in the `Parameters <#parameters>`__ paragraph below.


EC2 region

The EC2 region defines where your EC2 instances will be deployed. Some parameters may be different between regions (e.g. image id: ami-…). If you want to use multiple regions concurrently, you will need to instantiate this connector multiple times.

Cloud Client Connector

This field corresponds to the URL where the Orchestrator will download the tarball of the connector for the SlipStream Client. In a default installation the URL will be https://ip_or_hostname/downloads/ec2client.tgz where ip_or_hostname corresponds to the IP or the hostname of your SlipStream Server.

Orchestrator security group

The EC2 security group should allow TCP connexions from the Orchestrator itself to the SlipStream server and to the EC2 API. The default security group named default should normally work perfectly.

Image Id of the Orchestrator

The image id of the Orchestrator needs to match a Linux image with wget and python installed. An Ubuntu 12.04 or 14.04 will do the job perfectly (at the time or writing, for the region eu-west-1 the image id is ami-a0dd3dd7). EC2 image ids start with ami-. You can found them in the EC2 web interface.


The quota is a SlipStream feature which enables the SlipStream administrator to set a default quota for all users of a specified connector. You can also override this value for each user in the user profile. If this feature is disabled in the SlipStream Advanced section of this page, you can leave this field blank.

Orchestrator instance type

The instance type is a name which is linked to a hardware specification defined by EC2. You can find the list of all possible values here. The Orchestrator doesn’t need a big amount of resources so you can choose a small instance type (like t2.micro or t2.small).

Configure Native Images for This Connector Instance

Now you need to update SlipStream native images to add the image id and some parameters specific to EC2.

This can be done via the UI or via configuration file. Documentation about how to do it via configuration file can be found here Unique Cloud Identifier Configuration Files.

Please go on a SlipStream base image (e.g. Ubuntu 12.04) and click on the Edit button. Add the image id for EC2 in the section named Cloud Image Identifiers and Image Hierarchy.

And then configure the default amount of CPU and RAM on the tab ec2 (or the name you gave your EC2 connector earlier) of the section Cloud Configuration.

User Credentials

Now that the connector is configured and the native images updated, inform your users that they need to configure their credentials for EC2 in their user profile to take advantage of your new connector.
