Sandboxes

This pages describes sandboxes, which provide the environment for tracks.

What is a sandbox?
A sandbox is a self-contained environment created using actual products to match real-world scenarios. A sandbox can contain sandbox hosts which are containers or virtual machines. And you can add multiple hosts to a sandbox. 
Learners can access sandboxes using only a web browser. And with sandboxes, learners can experiment and learn without setting up anything themselves and worrying about breaking things.
See the overview for where the sandbox fits into the Instruqt environment.
Sandbox resources
A sandbox is made up of the following resources:
Containers
Virtual machines
Cloud accounts:
Google Cloud Platform (GCP) project
AWS account
Azure subscription
Secrets
Check these topics for more information about containers and virtual machines:
​Hosts and images​
​Machine types​
​
And check the cloud accounts topics for more information about cloud accounts.
Appearance
🌐 Web UI
💻 Instruqt CLI
In the Web UI, the sandbox appears within a track in the Sandbox tab:
sandboxcontainer
├── 01-creating-a-directory
│   ├── assignment.md
│   ├── check-container
│   ├── cleanup-container
│   ├── setup-container
│   └── solve-container
├── config.yml
└── track.yml
In Instruqt CLI, the sandbox appears as the config.yml file (line 8) in the main directory of the track. 
Sandbox properties
You specify a sandbox by setting its properties through the Web UI or Instruqt CLI. 
For Web UI, you will find the properties as fields in the Sandbox tab of the Track details. For Instruqt CLI, you will find the properties in the configuration file config.yml as in this example:
YAML
version: "3"
containers:
- name: container
  image: ubuntu
  shell: /bin/bash
  memory: 256
The following tables show the sandbox properties grouped by resource:

Virtual machine
Field
Description
Type
Required
Name
Name of the virtual machine. 

Visible to learners and becomes part of the short DNS hostname of the virtual machine.
string
Required
Image
The Google Compute Engine image to use for this virtual macine.

Instruqt needs permission to pull the image. 
string
Required
Machine type
The machine type of the virtual machine.

Overview of all supported machine types  (up to 32 vCPUs and 28.8 GB memory)
string
Required
Environment Variables
A map of key-value pairs that will be injected as environment variables.
map
Optional
Shell
Defaults to /bin/sh for maximum compatibility. Set this to /bin/bash for more features.
string
Optional
Allow external ingress
Allow inbound traffic from external sources.

Valid options: 
• http
• https
• high-ports

This feature is documented on the networking page: usage instructions.
[]string
Optional
​
GCP project
Field
Description
Type
Required
Name
The name of the GCP project.
string
Required
Services
Use this field to enable services on the Google Cloud project.

For a list of available services, visit the API library page or run gcloud services list --available. 

🚫You can not enable serviceusage.googleapis.com
list
Optional
Roles
Use this field to grant IAM roles to User and Service account on the Google Cloud project.
​
For a list of available roles, visit the Understanding roles page or run gcloud iam roles list.
​
Roles will default to the Owner role (roles/owner) if no roles are specified.
​
The Owner role will only be applied to the Service account. The User account will fall back to the Editor role (roles/editor). This is a limitation with Google Cloud IAM which does not allow configuring the Owner role for "external" Users.
​
⚠️ The Owner role gives full control to a project. To limit potential abuse, we suggest using more specialized roles that only give permissions to the resources/services required.
