0.36.2 - 2024-07-02

Fixed

  • Remove the return statement from detach_network_endpoint_group and attach_network_endpoint_group since the extended operation payload is set to nothing anyway

0.36.1 - 2024-07-02

Fixed

  • Remove the return statement from set_tags since the extended operation payload is set to nothing anyway

0.36.0 - 2024-07-01

Added

  • New probes to fetch all SLO and their health for a given URL

0.35.0 - 2024-07-01

Added

  • Fix new LB actions so that they properly figure the LB settings
  • Add the same actions for error faults

0.34.0 - 2024-07-01

Added

  • Bringing lueur as an optional dependency to start creating higher level actions/probes where data is automatically discovered from a live environment. The goal is to reduce boiler plate wherever we can.

0.33.0 - 2024-06-20

Changed

  • Always return falsey from chaosgcp.monitoring.proves.valid_slo_ratio_during_window when no data was found for the SLO
  • Bump dependencies

Fixed

  • Allow for empty route action block in load balancer actions

0.32.1 - 2024-05-31

### Fixed

  • Convert string to int. GCP returns int64 as a string to let the client to make the decision how to convert it. Python doesn't differentiate explicitely so we are left to let the Python VM make the right decision for us

0.32.0 - 2024-05-31

Added

  • Support for more typed value when verifying SLO with valid_slo_ratio_during_window

0.31.0 - 2024-05-28

Changed

  • Removed unusued ( character
  • Refactored code to locate the appropriate target

0.28.0 - 2024-05-24

Added

  • suspend_vm_instance and resume_vm_instance functions to

  • chaosgcp.compute.actions. These functions suspend a running

  • GCE VM instance and resume any suspended GCE VM respectively.

  • They can be called for action in experiments as follows:

     {
  "name" : "Suspend VM",
  "type" : "action",
      "provider": {
          	"type": "python",
  	        "module": "chaosgcp.compute.actions",
  	        "func": "suspend_vm_instance",
              "arguments" : {
                  "project_id" : "prj-shared-ntwk-prod",
                  "zone" : "us-central1-b",
                  "instance_name" : "mig-exp-ig-24w1"
              }
          }
      }

  • Added test cases for both the functions as well.

  • Added the chaosgcp.lb.probes.get_fault_injection_traffic_policy probe

  • with an expiration time determined by the given expiry_time_in_minutes

  • before experiment and revokes the specified IAM roles from the

  • provided members after the experiment:

      "controls": [
      {
"name": "gcp-iampolicy-timebound",
"provider": {
  "type": "python",
  "module": "chaosgcp.iam.controls.policy",
  "arguments": {
    "project_id":"myproject",
    "roles": ["roles/storage.admin"],
    "members": ["serviceAccount:[email protected]"],
    "expiry_time_in_minutes": 10
              }
          }

                      "appid": "123456"
                  }
              }
          }
      }
  ]

0.21.1 - 2024-03-15

Fixed

  • get_backend_service_health requires to be iterated over each network group

0.21.0 - 2024-03-15

0.18.0 - 2024-03-14

Added

  • The chaosgcp.gke.nodepool.actions.resize_nodepool action

Changed

  • Bump dependencies

0.17.1 - 2024-03-08

Changed

  • Bump dependencies

0.17.0 - 2024-03-08

Changed

  • Allow to retrieve the project id from the GCP_PROJECT_ID environment variable
  • Bump dependencies

0.16.1 - 2024-02-21

Fixed

  • Remove trailing function call in monitoring/actions.py module

0.16.0 - 2024-02-21

Changed

  • Switched from setuptoolsto pdm to package and manage the project. This also brings a much stricter dependency management support
  • Read package version using importlib_metadata
  • Drops supports for Python 3.7 as it's been EOL since June 2023
  • Adds Code of Conduct file

0.15.0 - 2023-12-08

Changed

  • All actions and probes now take optional project_id and region arguments so that they can be set on per activity basis. In that case, they take precedence over the configuration payload. But this also means, the configuration block can be left unset entirely for these fields
  • It is not expected anymore that you set a service account file to authenticate When none is provided, we delegate to the GCP client library to figure it out. This allows for newer authentication approaches supported by that client without relying on a less secure service account

Breaking

  • In the chaosgcp.cloudrun.probes.get_service probe, the name argument has been repurposed and has been renamed to parent. The name now expects the service name without its parent path as a prefix.
  • The extension will not raise an ActivityFailed exception when it could not load credentials explicitely set from the secrets. This is so the underlying client can attempt to load credentials directly and natively

0.14.1 - 2023-10-24

Fixed

  • Read region from the configuration block in the load balancer actions

0.14.0 - 2023-10-24

Added

Changed

0.13.0 - 2023-10-11

Added

  • the service_has_at_least_slo_across_time probe to use in a steady-state

0.12.3 - 2023-10-09

Changed

  • Make get_slo_health cross_series_reducer and per_series_aligner arguments are now strings and mapped back to their numeric value as it's friendlier that way

0.12.2 - 2023-10-09

Changed

  • Make get_slo_health group_by_fields argument support comma-separated strings

0.12.1 - 2023-10-09

Changed

  • Removed unused argument in get_slo_budget
  • Fix types for per_series_aligner and cross_series_reducer in get_slo_health

0.12.0 - 2023-10-09

Added

  • Support for regional LB access from the load-balancer actions
  • SLO probes

0.11.0 - 2023-08-23

Added

  • Also read credentials from GCP_APPLICATION_CREDENTIALS as an alternative to GOOGLE_APPLICATION_CREDENTIALS since the latter can lead to issues when running in GCP Cloud Run job which already provides its own credentials
