On April 3, 2020, we released Apigee hybrid runtime version 1.2.0.


New features and updates

Following are the new features and updates in this release.

A new virtual host configuration was added to specify routing rules

The new virtualhosts configuration feature addresses an issue where the order in which base paths were routed to multiple environments was uncertain. For details, see Configure virtual hosts. (150336519)

Beta release of the OASValidation policy

The OASValidation (OpenAPI Specification Validation) policy (Beta) enables you to validate an incoming request or response message against an OpenAPI 3.0 Specification (JSON or YAML). For more information, see OASValidation policy (Beta). (144949685)

Beta release of WebSocket support

Apigee hybrid supports WebSocket connections. API proxy clients can now request a protocol upgrade from HTTP to WebSockets. For details, see Using WebSockets (Beta).

Accessing policy secret values from Kubernetes secrets

A new feature lets you access values stored in a Kubernetes secret in proxy flow variables. For details, see Storing data in a Kubernetes secret. (133377603)

Apigee Operators (AO) element replaces ADAC and ADAH

Apigee Operators (AO) Creates and updates low level Kubernetes and Istio resources that are required to deploy and maintain the AD. For example, the controller carries out the release of message processors. Also validates the ApigeeDeployment configuration before persisting it in Kubernetes cluster. AO replaces Apigee Deployment Admissionhook (ADAH) and Apigee Deployment Controller (ADC). See ao in the Configuration property reference. (151250559)

Replace and deprecate certain cluster and project configuration properties

Two new configuration properties were added: k8sCluster and gcp. These properties replace the following deprecated properties: k8sClusterName, gcpRegion, and gcpProjectID. For details, see Configuration property reference. (146299599)

Persistent Volume expansion for Cassandra on Kubernetes

A process was added to expand the persistent volume used by apigee-cassandra to accommodate the storage needs, without needing to add more nodes just to increase storage. See Expand Cassandra persistent volumes. (138167919)

Support additional sources for certs, encryption keys and SAs

New configuration properties were added that provide greater flexibility in the way you specify TLS certificates, encryption keys, and service account keys. The new properties are listed below:

  • kmsEncryptionPath
  • kmsEncryptionSecret.key
  • kmsEncryptionSecret.name
  • cassandra.backup.serviceAccountSecretRef
  • cassandra.restore.serviceAccountSecretRef
  • envs[].cacheEncryptionPath
  • envs[].cacheEncryptionSecret.key
  • envs[].cacheEncryptionSecret.name
  • envs[].kmsEncryptionPath
  • envs[].kmsEncryptionSecret.key
  • envs[].kmsEncryptionSecret.name
  • envs[].serviceAccountSecretRefs.synchronizer
  • envs[].serviceAccountSecretRefs.udca
  • envs[].sslSecret
  • logger.serviceAccountSecretRef
  • mart.serviceAccountSecretRef
  • mart.sslSecret
  • metrics.serviceAccountSecretRef
  • synchronizer.serviceAccountSecretRef
  • udca.serviceAccountSecretRef

For more information, see the Configuration properties reference. (145303466)

Allow customers to obfuscate data before sending it to analytics

A feature was added that allows you to obfuscate certain analytics data before it is sent to the management plane. For details, see Obfuscate user data for analytics. (142578910)

Expand persistent volumes for statefulsets

A feature was added that allows you expand the persistent volume used by apigee-cassandra to accommodate the storage needs, without adding more compute power. For more information, see Expand persistent volumes for statefulsets. (138167919)

Minimum supported versions of GKE, Anthos, and AKS are upgraded

Apigee hybrid now supports GKE 1.14.x, Anthos 1.2, and AKS 1.14.x. (149578101)

Support TLS 1.3 for Northbound connections

Two new configuration properties allow you to set the minimum and maximum TLS version for the ingress: ingress.minTLSProtocolVersion and maxTLSProtocolVersion. Possible values are 1.0, 1.1, 1.2 and 1.3. For more information, see the Configuration properties reference. (117580780)

Support forward proxy configuration for hybrid runtime

HTTP forward proxying is now supported for API proxies deployed to an environment. For details, see Configure forward proxying. (148970527)

Support multiple hostAliases per environment

A new configuration property, envs[].hostAliases, has been added. This property lets you add multiple host aliases to an environment. Use this element instead of hostAlias, which has been deprecated. For details, see Adding multiple host aliases to an environment. (150738495)

Allow templates for property sets

A new element <PropertySetRef> was added to the <AssignVariable> element of the <AssignMessage> policy. <PropertySetRef> allows you to create a property set name/key pair dynamically. This feature is only available for API proxies deployed to Apigee hybrid. See AssignVariable. (148612340)

Bugs fixed

The following bugs are fixed in this release. This list is primarily for users checking to see if their support tickets have been fixed. It's not designed to provide detailed information for all users.

147685310 Runtime Synchronizer initialization failures due to failed GCP token fetch during initialization.
151115900 Runtime Periodic Internal Probe was not happening for HybridMART resulting in false positive results.

Known issues

The following table describes the known issues for this release:

Issue Description

Invalid HTTP Header error: The Istio ingress switches all incoming target responses to the HTTP2 protocol. Because the hybrid message processor only supports HTTP1, you may see the following error when an API proxy is called:

http2 error: Invalid HTTP header field was received: frame type: 1, stream: 1,
   name: [:authority], value: [domain_name]

If you see this error, you can take either of the following actions to correct the problem:

  • Modify the target service to omit the Host header in the response.
  • Remove the Host header using the AssignMessage policy in your API proxy if necessary.
144584813 If you create a debug session but the session does not yet have any transactions in it, then the List Debug Sessions API does not include the session in this list. The API only includes sessions in the response if the session contains at least one transaction.

The PopulateCache policy's expiration setting must be set to an explicit value between 1 and 30. For example:


Summary: There is a very high latency when using the API or UI to get your organization's deployment status. This latency can result in an HTTP 204 (No Content) or an HTTP 400 (Bad Request) response.

Workaround: Refresh your browser (or resend the request).
