v2.20.4 Armory Continuous Deployment Release (Spinnaker v1.20.6)

Release notes for Armory Continuous Deployment v2.20.4

2020/07/21 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 2.20.4 requires one of the following:

  • Armory-extended Halyard 1.9.4 or later.
  • Armory Operator 1.0.2 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>

For more information, see the following links:

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 will be removed in Spinnaker 1.21 (Armory 2.21). Please see the RFC for more details.

Breaking change: Kubernetes accounts with an unspecified providerVersion will now default to V2. Update your Halconfig to specify providerVersion: v1 for any Kubernetes accounts you are currently using with the V1 provider.

Known Issues

Dynamic Accounts for Kubernetes

Fixed in: 2.21

There is an issue with Dynamic Accounts for Kubernetes where the following issues occur:

  • Agents get removed but still run on schedule.
  • Force cache refresh times out.
  • If you have the clean up agent setup, your data randomly disappears and reappears.

These issues do not occur immediately, and you may even see modified accounts appear.

Upgrading from 2.18.x with MySQL used for Front50 renames the plugin_artifacts table

As a part of the upgrade from 2.18.x to 2.19.x or later, the table plugin_artifacts gets renamed to plugin_info. Downgrades from 2.19.x to 2.18.x do not revert the table name. The table remains named plugin_info, preventing access to the table.

You will see errors similar to the following:

2020-06-22 21:52:27.001  INFO 1 --- [           main] .s.f.m.p.DefaultPluginArtifactRepository : Warming Cache
2020-06-22 21:52:27.723 ERROR 1 --- [           main] .s.f.m.p.DefaultPluginArtifactRepository : Unable to warm cache: {}

org.springframework.jdbc.BadSqlGrammarException: jOOQ; bad SQL grammar [select max(last_modified_at) as `last_modified_at` from plugin_artifacts]; nested exception is java.sql.SQLSyntaxErrorException: Table 'front50_kinnon.plugin_artifacts' doesn't exist
	at org.jooq_3.12.3.MYSQL.debug(Unknown Source) ~[na:na]
	at org.springframework.jdbc.support.SQLExceptionSubclassTranslator.doTranslate(SQLExceptionSubclassTranslator.java:93) ~[spring-jdbc-5.1.14.RELEASE.jar:5.1.14.RELEASE]

This issue only occurs if you upgrade to 2.19.x or later and then downgrade to a version earlier than 2.19.x.


You can resolve this issue by rolling back changes to the MySQL database. For more information, see MySQL Table Name Change Error When Rolling Back Spinnaker (Undo Renamed Values).

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 Armory; 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.


  • CVE-2020-13790

This is an embedded dependency in OpenJDK11. A version of OpenJDK11 that addresses this CVE has only recently been released. The CVE will be fixed in an upcoming release. The risk to services users is low. The CVE deals with processing jpeg images in the Java Runtime Environment, a task Spinnaker services do not perform.

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

  • CVE-2020-14155


The following CVEs still exist in Clouddriver:

  • CVE-2020-1747
  • CVE-2017-18342
  • 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 exist 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.


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

  • CVE-2020-14422
  • CVE-2020-13757
