Docker containers. Lighter and faster than VMs; preferred for workstation hosts.
Note: private: true hides from learners — for backend-only services. entrypoint: bash overrides image default and pairs naturally with shell: /bin/bash.
Full Linux or Windows VMs. Required for kernel features, GUIs, nested virtualization.
Sizing: default to machine_type: over memory:+cpus:. Canonical sizing knob across most workshop-image families and partner-published custom images.
Pre-pointed browser tabs. URL accepts ${_SANDBOX_ID} interpolation, internal hostnames, or external URLs.
Pattern: point at a SaaS login page, surface credentials separately via [[ Instruqt-Var ]] in the assignment body.
Provisioned AWS account. Credentials auto-injected as INSTRUQT_AWS_ACCOUNT_<NAME>_*.
Two policies common: learner iam_policy (narrow) plus admin_iam_policy (broad) for setup. secrets: is the BYOC alternative when no provisioned account is needed.
Provisioned Azure subscription. services: are resource provider namespaces — pre-registered before handoff.
Auto-aliases: on a cloud-client base image, Terraform-style ARM_CLIENT_ID / ARM_CLIENT_SECRET / ARM_TENANT_ID / ARM_SUBSCRIPTION_ID are injected automatically.
Provisioned GCP project. services: are API names. SA key arrives base64-encoded.
Decode pattern: echo $INSTRUQT_GCP_PROJECT_LAB_SERVICE_ACCOUNT_KEY | base64 -d > /tmp/sa.json. Pair with trap “rm -f /tmp/sa.json” EXIT.
Named secrets injected as environment variables on every container and VM. Values set in the Instruqt platform UI, never in the source tree.
Always use this for credentials. Anything in environment: on a resource lives in the source tree forever and appears in the learner’s debug log. SSH keys, API tokens, license keys, registry credentials — all belong here, not in environment: or in lifecycle scripts.
name: uppercased with hyphens replaced by underscores. name: my-lab → prefix INSTRUQT_AWS_ACCOUNT_MY_LAB_.config.yml. Telltale: a cluster of credential secrets: with no matching cloud account block.secrets: values inside any of them.
