v2.21.1 Armory Continuous Deployment Release (Spinnaker™ v1.21.2)

Release notes for Armory Continuous Deployment v2.21.1

2020/08/06 Release Notes

Note: If you’re experiencing production issues after upgrading Spinnaker, rollback to a previous working version and please report issues to http://go.armory.io/support.

Required Halyard version

Armory 2.21.1 requires one of the following:

  • Armory-extended Halyard 1.9.4 or later.
  • Armory Operator 1.0.3 or later.

Breaking changes

Kubernetes deployment namespace

Upgrading to 2.20x or later introduces a breaking change in the Kubernetes provider for Spinnaker. Spinnaker now correctly interprets the namespace declared in your kubeconfig file and uses that namespace. Previously, Spinnaker deployed to the default namespace called default because of an error in how Spinnaker interpreted the namespace in the Kubernetes context.


Armory recommends using one of the following methods, which involve explicitly setting the namespace:

  • In your deployment manifests, declare the namespace you want to deploy to. Set to default if you want to maintain the previous behavior:

    apiVersion: batch/v1
    kind: Job
     generateName: <someName>
     # Set namespace to default if you want to maintain the previous behavior.
     namespace: <targetNamespace> 
  • In your kubeconfig, declare the namespace you want to deploy to. Set to default if you want to maintain the previous behavior:

    - context:
      cluster: <someCluster>
      # Set namespace to default if you want to maintain the previous behavior.
      namespace: <targetNamespace>

Introduced in: Armory 2.20

Spinnaker metrics

Metrics data, specifically the metric names, for Spinnaker changed. These changes are not backwards compatible and may result in broken third-party dashboards, such as Grafana dashboards.


  • Observability Plugin: Armory is working on updates to the Observability Plugin to remedy this issue. The plugin currently supports New Relic & Prometheus. Note that this resolution requires you to make updates to use the new metric names.

    For information about how to configure the Observability Plugin, see Monitoring Spinnaker with Prometheus.

    For information about how to install a plugin, see Spinnaker’s Plugin Users Guide.

  • Update existing dashboards: Change your dashboards and alerts to use the new metric names.

Although both workarounds involve updating your dashboards to use the new metric names, Armory recommends switching to the Observability plugin. Due to changes the Spinnaker project is making, the Observability plugin provides a long-term solution.

Affected versions: Armory 2.20.x or later (OSS 1.20.x)

HTTP sessions for Gate

Armory 2.19.x and higher include an upgrade to the Spring Boot dependency. This requires you to flush all the Gate sessions for your Spinnaker deployment. For more information, see Flushing Gate Sessions.

Scheduled removal of Kubernetes V1 provider

The Kubernetes V1 provider has been removed in Spinnaker 1.21 (Armory 2.21). Please see the RFC for more details.

If you still have any jobs that use the V1 provider, you will encounter an error. For more information, see Cloud providers.

Known Issues

SAML Authentication

Trying to login to Spinnaker using a SAML provider shows an error like the following:

{"timestamp":1597865813098,"status":500,"error":"Internal Server Error","message":"Error creating output document"}

This is caused by a version dependency bump in owasp esapi. No workaround exists.

Affected versions: 2.21.1, 2.21.0

Fixed versions: 2.21.2

Security update

We continue to make Spinnaker’s security a top priority. Although several CVEs are resolved, the following still exist:

Multiple services

CVE-2020-5410 was resolved in a previous version of Spinnaker; however, this CVE introduced a regression for users of Spring Cloud and has been rolled back. Armory will continue to monitor releases for a fix.


The following CVEs have been recently identified and will be addressed in an upcoming release:

  • CVE-2020-7692

The following CVEs still exist in Clouddriver:

  • CVE-2017-18342
  • CVE-2020-1747
  • CVE-2019-17638
  • CVE-2020-13757
  • CVE-2016-10745

All of them are embedded dependencies in the Google Cloud SDK. A version of the Google Cloud SDK addressing these CVEs has not been released. The risk to Clouddriver users is low. All four CVEs deal with untrusted input, which Clouddriver does not provide to the Google Cloud SDK. Additionally, users deploying to other cloud providers are not at risk for this vulnerability.

The following CVE also exists for Clouddriver:

  • CVE-2020-7014 deals with an Elasticsearch exploit related to token generation. Clouddriver only makes use of entity tags and does not allow for token generation or authentication.

The following CVEs will be triaged as part of a future release:

  • CVE-2020-7692

Armory has identified and is triaging the following CVEs in Terraformer, the service for the Terraform integration:

  • CVE-2020-15778


This release makes the following improvements:

  • Fixes an issue in 2.20.0 where Custom Job Stages fail. For more information, see the Known Issue.
  • Improves how the GitHub PR Validation for Pipelines-as-Code works. If there are no changes to a dinghyfile, PR Validation passes.
