Update

Lower Agent Timeouts

We have reduced agent timeouts from 5 minutes to just 3 minutes, and improved the lost agent cleanup service from 5 minutes to 1 minute! This enhancement offers significant benefits to our customers, particularly those utilizing spot instances for their agents.

With shorter timeouts, jobs now fail faster when spot instances can't compete on price, slashing the time it takes for pipelines to detect and recover from failures from 10 minutes to just 4 minutes. This means faster feedback loops, streamlined pipelines, and ultimately, accelerated development cycles.

Feature

Clusters Generally Available

Clusters will be enabled for all organizations on 26 February, 2024.

Clusters is a Buildkite feature used to manage and organize agents and queues, which:

allows teams to self-manage their Buildkite agent pools,
allows admins to create isolated sets of agents and pipelines within within a single Buildkite organization,
helps make agents and queues more discoverable across your organization, and
provides easily accessible queue metrics.

After the release all existing agents can be accessed through Unclustered grouping on the agents page.

Feature

Agent Job Tokens

Access tokens for agents will now be limited to the lifetime of the job. There is now a unique BUILDKITE_AGENT_ACCESS_TOKEN for each job that is run, which will stop working once the job finishes. This reduces the period of impact to the lifetime of the job if a BUILDKITE_AGENT_ACCESS_TOKEN is leaked from the agent’s environment.

Ensure you are running Buildkite Agent version v3.39.0 or later to take advantage of these tokens and v3.62.0 for all the latest improvements.

For more details, see the documentation.

Update

Docs updates to Pipelines landing page, GraphQL cookbook, and visual style

We tackled some quick wins the last week, including:

Creating a new landing page for Pipelines. This helps distinguish the product from the feature and provides clearer entry points for new users.
Adding a dedicated page to describe Pipelines' hybrid architecture.
Highlighting H3s when scrolling on a page.
Splitting the GraphQL cookbook into multiple pages to make it easier to navigate.
Updating the search component.
Applying general style updates across the site, from typography and tables to page layout and spacing.

And many more small changes. See the documentation to check them all out. ✨

Update

Enforce edit permissions check when accessing pipeline provider webhook URLs

Pipeline edit permissions are now required to view pipeline.provider.webhook_url. If the user does not have the correct permissions, a blank string will be shown in place of the webhook URL.

This change will also affect webhook payloads containing pipeline data. To ensure the greatest level of security, pipeline.provider.webhook_url will no longer be visible in these payloads.

Update

Single Organization Access Tokens

Starting today, newly created API Access Tokens will only access one organization. This update aims to enhance organizations' security by simplifying access token management. Administrators should be aware that tokens cannot be modified to include their organization after they have been originally created.

This change only affects newly created tokens. All existing tokens will remain unaffected by this change; however, existing tokens will not be able to add any additional organizations to their scope.

Deprecation

Upcoming change to the Buildkite API

To enhance the overall reliability and scalability, we are implementing changes to how Buildkite handles API GET requests that include a body in the payload starting September 18th.

As a result of these changes, any GET request to api.buildkite.com that includes a body will receive a 403 status (Forbidden) as a response.

This may impact legacy clients, particularly older versions of Buildkite's Terraform provider (< 0.15). To ensure compatibility, we recommend upgrading to the latest version of our Terraform provider.

During the week commencing August 28th, Buildkite will intermittently enable this change for short periods as a low-impact method of uncovering issues.

We value our customers and their experience with Buildkite, so we will directly communicate with any customers continuing to submit API GET requests with a body.

Thank you for your understanding and cooperation as we continue to improve our platform.

Update: We originally advised this change would occur on August 14th, we have delayed this change to September 18th.

Update

GraphQL Rate Limits

Buildkite has introduced new rate limits for the GraphQL API.

This update will improve performance, enhance security, and ensure fair usage across the Buildkite platform.

Please read the documentation to learn more about the GraphQL rate limits, specifically how to check your current usage:

Deprecation

GraphQL Build Retention Objects Deprecation

On 13 July 2023, there will be some deprecations in the GraphQL API. The following objects from the pipeline will be deprecated: buildRetentionEnabled, buildRetentionNumber, and buildRetentionPeriod.

To get more information about the pipeline schema and its changes, please refer to the documentation.

Update

Agent Tokens Removed from Buildkite UI after Creation

Effective from 24 July 2023, agent tokens in the Buildkite UI will undergo a significant modification. They will now behave similarly to API tokens, meaning that after creation, they will no longer be visible in the UI.

To ensure you have access to the complete token, it is crucial to save it immediately upon creation. This change aims to enhance the security of agent tokens within the Buildkite platform.

Please make a note of this update and adjust your workflows accordingly. If you have any questions or concerns, feel free to reach out to our support team (support@buildkite.com) for assistance.

Feature

Now available: June 2023 Release

Today we’re shipping 30+ new features to Buildkite 🚀

Some of the features I’m most excited about are:

🗂 Pipeline Templates let you have a shared set of step definitions you can use across your pipelines, and better yet, you can lock down all your pipelines in the organization to only those templates. Great for security and control at scale.
📈 We’ve added metrics to your cluster queues. You’ll now be able to see how many agents are connected, how many jobs are running, and what the current scheduled wait time for a job is.
🔨 Building upon our local Agent Job API that we shipped in the last release, Agent hooks can be written in any language, not just Bash. This allows us to work towards a future where you can write your hooks once and run them anywhere.

Check out the rest of the release here: https://buildkite.com/releases/2023-06

I'd love to hear your feedback on the release, send me an email any time: keith@buildkite.com

Feature

API token expiry policies

Security is job zero, it’s important for organizations to harden their defenses against lost or leaked credentials. Buildkite’s token expiry policy will automatically revoke tokens that are no longer in use from accessing your organizational information

Set your token expiry policy to either 30, 60, 90, 180, or 365 days. After which if a token has not been used for that period of time it will expire and no longer have access to your organization.

Update

Access Token Notifications

Buildkite has implemented additional security notifications to keep your data safer.

Security notifications empower customers to promptly address any token changes made to their accounts, ensuring data security and preventing unauthorised access.

Users will now receive an email when they create or update an access token associated with their account.

Update

Important Update to Terraform Provider

We're removing support for Import of agent tokens in the Terraform provider. This change coincides with the announcement in this changelog. From 4 July 2023 onwards, any resources or data-sources which are dependent on an agent token being present will likely fail to apply.

We recommend that you update your provider version to >=0.19.0. Any version below this will run a state refresh on the next Terraform operation and cause agent tokens in state to be set to nil, "". If these changes are then deployed, there is a risk that all agents in your organisation will have their tokens removed and no longer be able to connect to Buildkite.

Go to the v0.19.0 release

Go to the terraform registry

Deprecation

Agent Token being Deprecated from GraphQL APIs

At Buildkite we take your security seriously, because of that starting 22 June 2023 you will not be able to retrieve agent tokens for clustered and unclustered agents through the token attribute after it has been created through GraphQL APIs.

Update: The date for deprecation will be delayed to 4 July 2023 due to the breaking change introduced to Buildkite terraform provider. If you are a customer using the Terraform provider, please make sure to upgrade to version 0.19.0 beforehand.
