Changelog

0.5.0 January 23, 2026

  • Added the option to specify a git branch instead of the default one for each repository in each workspace.
  • Added options to retry provisioning a workspace and visualizing setup error logs.

  • Most Kubernetes objects created by CPS1 now have their names normalized. That is, their name is summarized to fit their type name length restriction and a random suffix is added to avoid collisions. This prevent some errors that could happen while provisioning environments with very large names that created resources with a very strict name size (e.g statefulsets).

  • Added a new configuration option to set which strategy to use for volume allocation for workspaces:

    • sharedPerUser: every workspace created by that user will consume a single volume from their namespace
    • isolatedPerWorkspace: every workspace gets its own isolated volume

The default strategy is isolatedPerWorkspace. To change it, configure the workspaceVolumes in the config object: 

workspaceVolumes:
  allocationStrategy: isolatedPerWorkspace  # Or "sharedPerUser"

Other options added to workspaceVolumes includes size, accessMode, and storageClass. Here is an example with the default values: 

workspaceVolumes:
  allocationStrategy: isolatedPerWorkspace
  size: 12Gi
  storageClass: null  # leaving it null means it will use the cluster default StorageClass
  accessMode: ReadWriteOnce

  • Renamed the contrib chart to catalog, as we feel this name describes its purpose more clearly.

  • Added an optional CronJob that pauses every environment. Configure the values of the platform chart to use it. Here are the default values: 

    environmentScheduler:
  enabled: false  # Change to true to enable
  serviceAccountName: "environment-scheduler"
  clusterRoleName: "environment-scheduler"
  clusterRoleBindingName: "environment-scheduler"
  cronJob:
    name: "environment-scheduler"
    schedule: "0 22 * * *"
    image:
      name: "docker.io/alpine/kubectl"
      tag: "1.34.2"

If you enable it with the default values every environment will be paused daily at 22:00.

  • Added some extra customization options for the platform, such as the Ingress class and their annotations. Here are the default values: 
    ingress:
  className: nginx
  annotations: {}

The internal registry size is also configurable: 

internalRegistry:
  volumeSize: 50Gi

  • Some options were included to control the pod placement for the CPS1 server (operator), gateway and internal OCI registry. The defaults are empty: 
    workloads:
  # See https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#nodeselector
  nodeSelector: {}
  # See https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#node-affinity
  affinity: {}
  # See https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/
  tolerations: []

Here is an example to provision those pods on nodes tainted with workload=addons:NoSchedule: 

workloads:
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
          - matchExpressions:
              - key: workload
                operator: In
                values:
                  - addons
  tolerations:
    - key: workload
      operator: Equal
      value: addons
      effect: NoSchedule

You can use this to create a node group with smaller nodes to run CPS1 and other cluster addons, while a node group with bigger nodes are available to run the development environments.

0.4.1 December 16, 2025

  • Version 0.3 added a change where every template is built with user namespaces for Kubernetes 1.33 or newer. But some Kubernetes distributions/worker nodes combinations still doesn't properly support this feature such as Kind (Kubernetes in Docker) and EKS clusters with Bottlerocket. Therefore, now this behavior is opt-in. You can enable it setting CPS1's config buildWithUserNamespaces to true (it is false by default).
  • Fixed an issue where an SSH channel would be closed before completely streaming an exec's stderr if the stdout finished streaming.

0.4.0 December 11, 2025

  • IDs from resources and workspaces are translated depending on the context to be used in Kubernetes objects name and CEL statements.
  • More variables are available in CEL contexts to refer to services exposed by other workspaces. Now it's easy to connect multiple microservices within a single environment:
  • The SSH gateway was updated to support JetBrains Gateway.
  • Fixed a bug that could make a new environment page become empty
  • Fixed the build logs display for templates with multiple workspaces

0.3.1 December 02, 2025

  • Add validations in UI and CRDs to block invalid Resources and Workspaces IDs

0.3.0 December 02, 2025

  • Add graceful shutdown to the SSH gateway
  • Fix a security vulnerability where a custom built malicious SSH client could crash the SSH gateway
  • Improve the web UI performance by removing some redundant network requests
  • Add support for Kubernetes 1.34
  • Fix progress display when a Workspace is starting
  • Make the pause/resume button more responsive
  • Fix the workspace list showing deleted workspaces

  • Sort template options by name when starting a worskpace
  • Build images isolated in user namespaces when possible (kubernetes 1.33 or newer and Linux kernel 6.3 or newer)
  • Harden some security settings for workspace pods
  • Add ResourceSets, Workspaces and Environments CRDs
  • Add TemplateSnapshot and EnvironmentSnapshot
