Coiled Cloud Release Notes

These release notes are related to updates for

12 January 2022


  • Fixed issue where setting nthreads when launching a cluster wasn’t respected. You can override worker worker_options={"nthreads": <number of threads>} passed to the coiled.Cluster constructor.

  • Removed references to Azure from Coiled Cloud


  • For AWS, VPC creation that runs when you set your backend options to run Coiled on your cloud provider of choice will now create one subnet for each Availability Zone in the region you chose to run Coiled.

  • You can now specify an Availability Zone when creating a cluster (you might need to rerun the VPC creation process).

  • Periodic cleanup will now cleanup resources in different Availability Zones.


  • Added warning in the Firewall and Networking section of the cloud providers documentation that this feature is under active development and is in an experimental phase.

15 December 2021


  • Fixed a frontend issue where a pro customer’s payment info was not showing up even though it had been entered.

  • Fixed an intermittent issue where users for some credit cards were unable to enter their security code. This has been fixed and all Credit Cards should work consistently.


  • Dask workers now use public IPs so that NAT Gateway is no longer needed; ingress to workers is still blocked. Bring your own network can disable public IPs for workers by setting the the give_workers_public_ip option.

  • Added a UI for bring your own network so network options can also be configured through the UI when selecting your backend.

  • Free tier account usage is still on an opt-in model. If you are a new user please contact to enable software environments and cluster creations.

  • Azure functionality has been removed and disabled for users. Users previously hosted on Coiled-hosted Azure have been migrated to the AWS backend.


01 December 2021


  • Added ability to manage API access tokens using (optional) expiration dates or manual revocation. Added support for managing API tokens via the Coiled Python client.

  • Added account limit alert when 99% of the quota is used and when your account has reached its quota limit.

  • Changed the default to use on-demand VMs for Dask workers as opposed to spot or preemptible instances. Backend options can still be set to use spot or preemptible instances, see AWS backend options or GCP backend options.

  • Added ability to use pre-existing cloud resources (e.g., VPC, subnets, security groups) when running Coiled in your own cloud provider account.


  • Coiled Notebooks and Coiled Jobs have been deprecated.


  • As part of upcoming deprecation of the Azure cloud provider backend, the documentation related to Azure has been removed.

  • Coiled client version of 0.0.55 or higher is required - please update your client if needed.

10 November 2021


  • Dask workers will now use all CPU/Memory available for the instance type in which they have been created. In the past, workers would be limited by your CPU/Memory specification.


  • Moved the Coiled Subscription tab up on the account settings page to make it easier for you to see how many credits you have used so far.

  • If you are using Coiled on your cloud provider, you can now customize ingress rules for the firewall/security group created by Coiled by specifying ingress ports and a CIDR block.


  • Coiled Notebooks and Coiled Jobs were an experimental feature which is being deprecated. After December 1, 2021, these will no longer be available.


27 October 2021


  • The route table for the private subnet that is created when Coiled creates a VPC in your AWS account, is now called coiled-vm-private-router instead of coiled-vm-public-router.

  • Mitigate Rate Limit exceptions when performing some actions like scaling clusters, which should improve cluster reliability.

  • Software environment names must now be lowercase only.


  • Removed experimental warnings for GCP and Azure in the UI when choosing a backend option for an account.

  • Removed fallback option to fetch logs from instances via SSH.


  • Removed experimental notes for GCP and Azure in the respective section of the documentation for these backends.

  • Updated default worker_memory to 8GiB in a few pages where it was saying that the default was 16GiB.

  • Added a section about network architecture to the Security & Privacy page.

  • Added a tutorial on Selecting Instance Types.

  • Added a tutorial on Selecting GPU Types.

  • Added section on selecting instance types in the documentation page Creating clusters.

  • Added a Networking section on the documentation page for the AWS Backend that explains how you can specify your AWS security groups using the new arguments enable_public_http, enable_public_ssh and disable_public_ingress.

13 October 2021


  • Environment variables sent to the Cluster with the keyword argument environ= are now being converted to strings, which fixes occasional failures when sending non-string values to the Cluster.


  • You can now use Coiled in your own GCP account. Please refer to the GCP Backend documentation.

  • You can now use Coiled in your own Azure account.

  • You can now select a region or zone when launching clusters in GCP.

  • You can now create software environments using Docker images stored in your private ECR (AWS), ACR (Azure) or GAR (GCP) container registries, in addition to Docker Hub and other registries, by calling coiled.create_software_environment(container="<URI>").

  • Coiled now collects statistical profiling data from your Dask clusters. This data is visualized as a flame graph on the Analytics page for individual clusters.

  • You can now hide/show columns in the Clusters Dashboard. The options are: Id, Cluster Name, Created By, Status, Num Workers, Software Environment, Cost (current), Cost(total), Last Seen, Backend, Runtime, Spot/Preemptible.

  • Improve log filtering for AWS when viewing logs in the Coiled UI.


  • Added a new example on using the Dask Snowflake connector.

  • Fix link to Coiled’s privacy policy in the Security & Privacy page.

  • Added new section in the GPUs documentation to demonstrate the use how of GPUs with the Afar library to run remote commands.

  • Fix issue with workers not being created when users create a new Cluster using the AWS backend.

  • Resolve error that was causing Clusters to shut down immediately upon creation for users using the AWS backend.

  • Fix issue that was causing the Cluster Dashboard table to show zero workers count even though the workers were created and connected to the scheduler.


  • Add label containing the instance name to notification when running coiled.get_notifications().


  • Fix typo in CLI command, documentation mentioned coiled inspect but the right command is coiled env inspect.

  • Update Teams page to better explain the distinction between Accounts and Teams.
