Recent Updates

  • 2025.03.19.3

    Private Load Balancing, New Pipeline Steps, and Advanced Sysctl Commands

    This update brings a focus on flexibility in environments and pipelines. Users will enjoy a new pipeline step (deprecate container) and also new ways to use named resource identifiers. Load balancers can now be run without a public IP's assigned to them opening the door to more dynamic, zero-trust architectures. In the API, filtering got an upgrade with the addition of filtering on deprecated tag for containers. Finally, users who need to take deeper control of IPv6 settings can use the disable_ipv6 for further granularity in networking control on containers.

      Private Load Balancers

      Load balancers can now be enabled without public IPs. This is valuable for load-balancing private applications within an environment that might not need public internet access -- i.e. Cloudflare tunnels.

    • improvement

      Named Arguments in Resource Identifiers

      We now support arguments like deployment.version and deployment.tag as parameters to a resource identifier in pipelines. With these arguments, teams can build significantly more flexible pipelines furthering automation efforts.

    • added

      Deprecate Containers Step

      Containers can now be deprecated via pipelines.

    • improvement

      Jobs Endpoint

      The jobs endpoint wasn't properly limited to the expected capability for API keys.

    • improvement

      Filtering via Deprecation State

      In the API, containers can now be filtered by their deprecation state using ?filter[deprecated]=true/false

    • added

      Disable IPv6

      While we don't recommend disabling IPv6, there may be a specific reason where it is required. By setting net.ipv6.conf.all.disable_ip6 to 1, Cycle now fully disables IPv6 for a container.

  • 2025.02.20.1

    Improved Load Balancer Routing, Upgraded TLS, and Administrative Flexibility

    This release brings users a handful of solid improvements and a couple needed fixes. The V1 load balancer routers got a fix to path matching in routes and also a major improvement to the predictability of the router chosen. Now the first match will always win. On the security front, a now deprecated cryptography alorithm was removed and the platform now enforces a higher minimum TLS version. Finally, hub billing now support multiple billing contacts, expanding flexibility on who in an organization receives important emails.

    • improvement

      Integration Deprecations

      Hub integrations can now be deprecated. This demarkation has no effect on existing integrations but will prevent new additions of that integration from being added.

    • improvement

      SSH TLS Update

      Removed a now deprecated crypto algorithm and now enforced a minimum TLS version of 1.3

    • fixed

      Route Matching Predictability

      We've refactored how the LB makes routing decisions to eliminate a race condition that existed with path matching. Now, router matching is significantly faster and more predictable, with the first (top) match always winning.

    • improvement

      Billing Contact

      Organizations can now update their billing and tax information within the portal. Additionally, organizations can subscribe additional email addresses to invoice notifications.

    • improvement

      User Uploaded Wildcard TLS Certificates

      We've expanded the functionality of user uploaded certificates to work with wildcard certificates. While we've supported LetsEncrypt wildcards for years, our recently added 'user uploaded certificates' did not support wildcards until now.

  • 2025.01.21.2

    New Load Balancer Metrics, Log Drain Format, and Solid Platform Fixes

    This update features a slew of more granular load balancer metrics for Cycle's V1 load balancer. These new metrics also come with additional tooling in the portal that allows users to make specific filters when debugging network traffic. The log drain format can now be customized, offering higher flexibility for integrations with existing services, and the platform received some great fixes that should lead to even more stability.

    • improvement

      Log Drain Format

      The format of log output can now be customized via the container config integration.

    • added

      Load Balancer Metrics

      The V1 load balancer now collects more granular metrics that can be helpful in diagnosing application issues. A restart of the load balancer is required to gain these additional metrics. Additionally, users can now filter load balancer metrics based on domains and HTTP response codes in the load balancer's URLs tab.

    • fixed

      File Ownership

      We found a bug during our OCI image merging where, under certain conditions, files could lose their respective user/group ownership. This is fixed for all future image builds.

    • fixed

      Instance Migration

      No longer allow an instance to be migrated if an existing migration is already occurring for that instance.

    • fixed

      Migration Deadlock

      If an instance failed to migrate after 16 attempts, it could cause a node deadlock preventing future actions on that server.

  • 2025.01.14.3

    Stack Build Logs, Stability Improvements, and Better Auto-Scaling

    In this release, users will find a wonderful new feature in Stack build logs . These logs will give insight into debugging stack builds that, in the past, have been more cumbersome to unpack. Alongside the stack build logs are a slew of stability improvements including a new agent logging mechanism that will enable even more resiliency to each server node during times of high usage. Additionally, auto-scaling was improved, requiring fewer window intervals before a scaling event can happen, resulting in an even more responsive auto-scaling from the platform.

    • improvement

      Metric Label Standardization

      We noticed a few inconsistencies in the naming conventions for metric/event labels. While they're now fixed, certain graphs within the portal will take a little time to populate with new data.

    • added

      Stack Build Logs

      Stacks now generate build logs that detail the overall build of images, stack parsing, etc, making it significantly easier to debug variable/stack formatting issues.

    • improvement

      External Log Draining

      Although this was beta released in December's build, we've made a number of optimizations to provide more context (via HTTP headers) while also reducing the amount of redundant meta information in the POST body.

    • fixed

      Container Reimage / Deleted Instances

      If a container was reimaged immediately after a scale event, any deleted instances would be undeleted.

    • added

      Block Storage / Raw Volumes

      While not accessible yet, we've added the ability to create volumes as raw block devices on compute nodes -- preparing for some soon to be announced features.

    • added

      Migrating Block Storage Volumes

      Support the ability to move block storage volumes between compute nodes.

    • improvement

      GCP Generation 3 + 4 Models

      We've compiled the required kernel modules into CycleOS to support the generation 3 and 4 (c3, c4, n3, m3) and accelerator (GPU) GCP machine types.

    • improvement

      Autoscaling Threshold Calculation

      We rebuilt the logic for network / bandwidth scaling thresholds to enable more responsive scaling. Previously, network scaling events required two interval windows to pass before a scaling event could occur.

    • added

      CycleOS Build Version

      Servers now report their CycleOS build version during their check-ins. This version is also displayed in the portal.

    • added

      Agent/Logging Volume

      Following a restart of the server, CycleOS will now build a dedicated 2GB volume for storing logs. By moving logs to their own volume, nodes will no longer deadlock / become unresponsive if disk usage reaches 100%.

    • improvement

      Hub Delete Prevention

      Hubs with active servers can no longer be deleted, unless the 'force' flag is specified.

    • fixed

      Attached Storage Size Customization

      When deploying servers at AWS or GCP, users can customize the size of the underlying block device. This functionality was broken in December's release.

    • improvement

      Cycle IPs in LB WAF

      Previously, it was possible to accidentally block VPN configuration via the portal by applying restrictive rules to the WAF (web application firewall). Now, the WAF will automatically detect the necessary Cycle IPs to allow VPN configuration without organizations needing to manage the IP list themselves.

  • 2024.12.16.1

    Support for More AWS Regions + Availability Zones, Log Draining, and More

    This latest update brings our users several new features and lots of improvements that are aimed at enhancing flexibility, integration, and usability. Servers being deployed through AWS will now have the option to choose individual availability zones per server, in the given region. We've also enabled several new AWS regions to deploy from. Log draining is now natively supported through webhooks, DNS caching has been improved, and load balancer metrics now auto discover ports from container configuration.

    • added

      Support for AWS Availability Zones

      While Cycle has always favored multi-region deployments, we now also support multi-availability zone deployments at AWS. This brings our AWS integration inline with our GCP integration.

    • improvement

      Support for Additional AWS Regions

      We realized there were 4 AWS regions which we didn't support due to an API filtering limitation, that has been resolved and we now support all AWS non-GovCloud regions.

    • added

      External Log Draining

      On a per-container basis, Cycle can now push your logs to an external source via an HTTPS webhook, enabling better integration with Datadog, Middleware, and other log aggregators.

    • improvement

      Variable Support for Pipeline Webhooks

      You can now utilize pipeline variables in your POST/GET webhooks, enabling deeper integrations with your external development / devops tools.

    • improvement

      Optimized DNS Caching

      We've tweaked our caching logic to support more generalized matching while still preventing DNS cache poisoning attacks.

    • added

      Support for ACH Payments

      Our US clients can now pay their invoices by ACH instead of credit cards.

    • improvement

      Portal: Load Balancer Metrics

      We now auto-discover controllers based on active ports, making it easier to observe traffic into your load balancer.

  • 2024.11.25.1

    Enhanced Security Options and Big Monitoring Improvements

    Hubs get deeper security options as this update introduces the ability to require two factor authentication for all users to sign in. Monitoring also makes some major leaps forward with new graphs located in several different places throughout the portal, showcasing specific container and instances telemetry. Keep your eyes peeled, the next update will be one of our biggest yet!

    • added

      Container Monitoring Graphs

      Gain more visibility into your top (RAM, CPU, Network) container instances scoped to: containers, environments, and clusters.

    • improvement

      Reserved Resources for Cycle

      Previously, under times of high cpu load/ram usage, Cycle agents would occasionally start failing to checkin. Now, we set aside a small portion of resources to ensure the agent can always maintain communication and control.

    • added

      User-Supplied TLS Certificates

      Need to use your own TLS certificates for compliance reasons? Now you can upload certificates via the Portal and API.

    • added

      Resource Allocation Meters

      Improved resource allocation meters on both the cluster and server view using new monitoring data.

    • added

      Enforcable 2FA

      Hub owners can now enforce two-factor authentication for all users within a hub.

    • fixed

      Git Clones With Hashes

      Git hashes within the non-'main' branch would fail unless they were one of the newest commits. This has been fixed.

    • fixed

      Scoped Variable Files

      When a container no longer has access to a scoped variable, the underlying file is deleted now. Previously, the file would remain with the old value.

    • added

      Pipeline Subqueues

      While Cycle enables parallel runs of different pipelines, it queues the runs of a single pipeline. With pipeline subqueues, organizations can spin off parallel runs of the same pipeline. Note, this is an advanced feature for specific use cases.

    • improvement

      Portal Fixes

      Dozens of smaller UI tweaks within the portal.

    • improvement

      Node Time Sync

      The platform has moved from a 12 hour sync to a ten minute sync which should drastically reduce the chance for time drift between nodes.
