GCP

Running VMs on behalf of a service account

Like all major clouds, GCP supports running a VM on behalf of a managed identity using a service account. Now you can assign a service account to a GCP VM with dstack by specifying the vm_service_account property in the GCP config:

type: gcp
project_id: myproject
vm_service_account: [email protected]
creds:
  type: default

Assigning a service account to a VM can be used to access GCP resources from within runs. Another use case is using firewall rules that rely on the service account as the target. Such rules are typical for Shared VPC setups when admins of a host project can create firewall rules for service projects based on their service accounts.

Volumes

Creating user home directory automatically

Following support for non-root users in Docker images, dstack improves handling of users' home directories. Most importantly, the HOME environment variable is set according to /etc/passwd, and the home directory is created automatically if it does not exist.

The update opens up new possibilities including the use of an empty volume for /home:

type: dev-environment
ide: vscode
image: ubuntu
user: ubuntu
volumes:
  - volume-aws:/home

AWS volumes with non-Nitro instances

dstack users previously reported AWS Volumes not working with some instance types. This is now fixed and tested for all instance types supported by dstack including older Xen-based instances like the P3 family.

Deprecations

• The home_dir and setup parameters in run configurations have been deprecated. If you're using setup, move setup commands to the top of init.
