Virtual machines & cloud resources

How to create a custom Docker image?

Before creating your custom Docker image, make sure that the image you need is not already available on the Docker hub. To get started on building your own Docker image, head over to the Docker documentation.

See also this page for making the image available to Instruqt:

We currently do not support Windows based container images.

How to create a custom Virtual Machine image?

Our virtual machine images run on Google Cloud. To create your own vm image, head over to the Packer documentation. If you need some inspiration, you can browse our github organization and search for our packer repositories. If you need help, please reach out to us on Slack.

How to run Windows based VM images?

The Instruqt platform currently assumes that the virtual machines in sandbox environments are Linux based. That means Windows support is limited.

What currently works:

  • Network connectivity between hosts, including DNS resolution based on host names defined in the environment configuration.

  • Injection of environment variables, that are defined in the environment configuration.

  • Injection of instruqt user with password Passw0rd!, to facilitate interaction from others hosts in the environment.

What does NOT work yet:

Full Windows VM support is on our roadmap.

Work-around for Windows based environments

However, it is still possible to run Windows based images as part of sandbox environments. To interact with these images we support the following work-around:

  • Create a sandbox environment with two images; 1 Linux based, and 1 Windows based

    • The Windows VM will run your software.

    • The Linux VM is used as a proxy to the Windows VM for running life cycle scripts, and providing terminal access.

  • Create a Windows based VM image, that has:

We have create an example track for this work-around. The example is based on Windows Server 2019, and includes Myrtille and OpenSSH for connectivity.

You can play the example track here: And the source code is available at:

How to run a desktop application on Instruqt?

It depends! Since we base Instruqt around Linux, you can run most Linux based applications right on Instruqt. However, if you intend on running a Windows based application, this is currently possible, but only through a workaround. Please reach out to us by joining us on Slack so we can get you started.
