On-prem clusters

Network

The dstack pool add-ssh command now supports the --network argument. Use this argument if you want to use multiple instances that share the same private network as a cluster to run multi-node tasks.

The --network argument accepts the IP address range (CIDR) of the private network of the instance.

Example:

dstack pool add-ssh -i ~/.ssh/id_rsa [email protected] --network 10.0.0.0/24

Once you've added multiple instances with the same network value, you'll be able to use them as a cluster to run multi-node tasks.

Private subnets

By default, dstack uses public IPs for SSH access to running instances, requiring public subnets in the VPC. The new update allows AWS instances to use private subnets instead.

To create instances only in private subnets, set public_ips to false in the AWS backend settings:

type: aws
  creds:
    type: default
  vpc_ids:
     ...
  public_ips: false

Note

  • Both dstack server and the dstack CLI should have access to the private subnet to access instances.
  • If you want running instances to access the Internet, the private subnets need to have a NAT gateway.

Gateways

dstack apply

Previously, to create or update gateways, one had to use the dstack gateway create or dstack gateway update commands.
Now, it's possible to define a gateway configuration via YAML and create or update it using the dstack apply command.

Example:

type: gateway
name: example-gateway

backend: gcp
region: europe-west1
domain: example.com
dstack apply -f examples/deployment/gateway.dstack.yml

For now, the dstack apply command only supports the gateway configuration type. Soon, it will also support dev-environment, task, and service, replacing the dstack run command.

The dstack destroy command can be used to delete resources.

Private gateways

By default, gateways are deployed using public subnets. Since 0.18.2, it is now possible to deploy gateways using private subnets. To do this, you need to set public_ips to false and specify the ARN of a certificate from AWS Certificate Manager.

type: gateway
name: example-gateway

backend: aws
region: eu-west-1
domain: "example.com"

public_ip: false
certificate:
  type: acm
  arn: "arn:aws:acm:eu-west-1:3515152512515:certificate/3251511125--1241-1224-121251515125"

In this case, dstack will deploy the gateway in a private subnet behind a load balancer using the specified certificate.

Note

Private gateways are currently supported only for AWS.

On-prem servers

Now you can add your own servers as pool instances:

dstack pool add-ssh -i ~/.ssh/id_rsa [email protected]

Note

The server should be pre-installed with CUDA 12.1 and NVIDIA Docker.

Configuration

All .dstack/profiles.yml properties now can be specified via run configurations:

type: dev-environment

ide: vscode

spot_policy: auto
backends: ["aws"]

regions: ["eu-west-1", "eu-west-2"]

instance_types: ["p3.8xlarge", "p3.16xlarge"]
max_price: 2.0

max_duration: 1d

New examples 🔥🔥

Thanks to the contribution from @deep-diver, we got two new examples:

Other

  • Configuring VPCs using their IDs (via vpc_ids in server/config.yml)
  • Support for global profiles (via ~/.dstack/profiles.yml)
  • Updated the default environment variables (DSTACK_RUN_NAME, DSTACK_GPUS_NUM, DSTACK_NODES_NUM, DSTACK_NODE_RANK, and DSTACK_MASTER_NODE_IP)
  • It’s now possible to use NVIDIA A10 GPU on Azure
  • More granular permissions for Azure

RunPod

The update adds the long-awaited integration with RunPod, a distributed GPU cloud that offers GPUs at affordable prices.

To use RunPod, specify your RunPod API key in ~/.dstack/server/config.yml:

projects:
- name: main
  backends:
  - type: runpod
    creds:
      type: api_key
      api_key: US9XTPDIV8AR42MMINY8TCKRB8S4E7LNRQ6CAUQ9

Once the server is restarted, go ahead and run workloads.

Clusters

Another major change with the update is the ability to run multi-node tasks over an interconnected cluster of instances.

type: task

nodes: 2

commands:
  - git clone https://github.com/r4victor/pytorch-distributed-resnet.git
  - cd pytorch-distributed-resnet
  - mkdir -p data
  - cd data
  - wget -c --quiet https://www.cs.toronto.edu/~kriz/cifar-10-python.tar.gz
  - tar -xvzf cifar-10-python.tar.gz
  - cd ..
  - pip3 install -r requirements.txt torch
  - mkdir -p saved_models
  - torchrun --nproc_per_node=$DSTACK_GPUS_PER_NODE 
     --node_rank=$DSTACK_NODE_RANK 
     --nnodes=$DSTACK_NODES_NUM
     --master_addr=$DSTACK_MASTER_NODE_IP
     --master_port=8008 resnet_ddp.py 
     --num_epochs 20

resources:
  gpu: 1

Currently supported providers for this feature include AWS, GCP, and Azure.

Other

  • The commands property is now not required for tasks and services if you use an image that has a default entrypoint configured.
  • The permissions required for using dstack with GCP are more granular.

Service auto-scaling

Previously, dstack always served services as single replicas. While this is suitable for development, in production, the service must automatically scale based on the load.

That's why in 0.17.0, we extended dstack with the capability to configure replicas (the number of replicas) as well as scaling (the auto-scaling policy).

Regions and instance types

The update brings support for specifying regions and instance types (in dstack run and .dstack/profiles.yml)

Environment variables

Firstly, it's now possible to configure an environment variable in the configuration without hardcoding its value. Secondly, dstack run now inherits environment variables from the current process.

For more details on these new features, check the changelog.

CUDO Compute

The 0.16.4 update introduces the cudo backend, which allows running workloads with CUDO Compute, a cloud GPU marketplace.

To configure the cudo backend, you simply need to specify your CUDO Compute project ID and API key:

projects:
- name: main
  backends:
  - type: cudo
    project_id: my-cudo-project
    creds:
      type: api_key
      api_key: 7487240a466624b48de22865589

Once it's done, you can restart the dstack server and use the dstack CLI or API to run workloads.

Note

Limitations

  • The dstack gateway feature is not yet compatible with cudo, but it is expected to be supported in version 0.17.0,
    planned for release within a week.
  • The cudo backend cannot yet be used with dstack Sky, but it will also be enabled within a week.

Pools

The 0.16.0 release is the next major update, which, in addition to many bug fixes, introduces pools, a major new feature that enables a more efficient way to manage instance lifecycles and reuse instances across runs.

dstack run

Previously, when running a dev environment, task, or service, dstack provisioned an instance in a configured
backend, and upon completion of the run, deleted the instance.

Now, when using the dstack run command, it tries to reuse an instance from a pool. If no ready instance meets the
requirements, dstack automatically provisions a new one and adds it to the pool.

Once the workload finishes, the instance is marked as idle.
If the instance remains idle for the configured duration, dstack tears it down.

dstack pool

The dstack pool command allows for managing instances within pools.

To manually add an instance to a pool, use dstack pool add:

dstack pool add --gpu 80GB --idle-duration 1d

The dstack pool add command allows specifying resource requirements, along with the spot policy, idle duration, max
price, retry policy, and other policies.

If no idle duration is configured, by default, dstack sets it to 72h.
To override it, use the --idle-duration DURATION argument.

To learn more about pools, refer to the official documentation. To learn more about 0.16.0, refer to the changelog.
