On January 27, 2020, Google released Apigee hybrid runtime version 1.1.0. This section describes new features and changes released in version 1.1.0.

Upgrading

You cannot upgrade from 1.0.0 to 1.1.0, and the new version is not backward compatible with version 1.0.0. Version 1.1.0 requires a new installation.

New features and improvements

Apigee Connect (Alpha release)

Apigee Connect Alpha allows the Apigee hybrid MART service to connect to the management plane without requiring you to expose the MART endpoint. If you use Apigee Connect, you do not need to configure the MART ingress gateway with a host alias and an authorized DNS certificate. For details, please contact your Apigee representative.

Base path routing

Base path routing allows you to configure and manage how Apigee hybrid routes API proxy calls to specific environments. For details, see Configure base path routing.

Changes

The following changes have been made for hybrid runtime version 1.1.0. Some of these changes, as noted, are not backward incompatible with version 1.0.0.

  • The apigeectl CLI now installs Istio in the istio-system namespace. This is the default namespace for Istio. This change is backward incompatible with hybrid version 1.0.0.
  • The apigeectl CLI now installs CertManager into the cert-manager namespace. This change is backward incompatible with hybrid version 1.0.0.
  • The supported version of Istio deployed with Apigee hybrid runtime has been migrated to 1.4.2 because version 1.2.x is no longer supported.

Bugs fixed

The following issues listed in the Apigee hybrid 1.0.0 release notes have been fixed:

Issue Description
144886537 Base path routing is not working in Apigee hybrid v1.0.0. When the overrides is setup to route to different environments with the same hostAlias, the ingress does not route to the environment based on path.
143774187 The hybrid UI displays the label "Company" in the Apps view.

Known issues

The following table describes the known issues for this release:

Issue Description
N/A You cannot use a "*" for the hostAlias property for both the mart and envs configurations. The best practice is to use a specific hostname for the mart configuration.
N/A Setting HTTP_PROXY, HTTPS_PROXY, and NO_PROXY variables is not supported in the Apigee Connect Alpha version.
N/A

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.
144436206 In the Cache Performance view, the Cache Hit Ratio calculation is incorrect.
144321491 Apigee hybrid logs "Creating missing cache" notifications that indicate a potential performance degradation. These messages are expected and can be ignored.
144321144 Proxies with secure virtual hosts cannot be reloaded.
144286363

Debug mask in env.json does not mask response data.

The following API to update the env.json debug mask with a responseJSONPaths field does not work:

PATCH /v1/organizations/org/environments/env/debugmask?replaceRepeatedFields=true
{
  "responseJSONPaths": ["$.maskedDataEnv"]
}

To work around this issue with trace, you can delete an entire trace session in the UI, or you can use the trace APIs to delete individual transactions within a session.

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

<ExpirySettings>
  <TimeoutInSec>30</TimeoutInSec>
</ExpirySettings>
133192879

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).
