Connectivity Link Technology Preview features Connectivity Link supports Red Hat OpenShift Service Mesh 3.0 Technology Preview 2 as the required Gateway API provider. For more information, see the OpenShift Service Mesh documentation . Important Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. Technology Preview features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information, see Red Hat Technology Preview Features - Scope of Support . 1.3. Connectivity Link Developer Preview features Connectivity Link introduces the API controller 1.0 Developer Preview, which is based on the Apicurio community project and includes the following components: API designer based on Apicurio Studio API catalog based on Apicurio Registry For more information, see Getting Started with API controller 1.0 Developer Preview . Important Developer Preview features are not supported by Red Hat in any way and are not functionally complete or production-ready. Do not use Developer Preview features for production or business-critical workloads. Developer Preview features provide early access to functionality in advance of possible inclusion in a Red Hat product offering. Customers can use these features to test functionality and provide feedback during the development process. Developer Preview features might not have any documentation, are subject to change or removal at any time, and have received limited testing. Red Hat might provide ways to submit feedback on Developer Preview features without an associated SLA. For more information, see Red Hat Developer Preview - Scope of Support . Red Hat customers can provide feedback on Developer Preview features through your account teams. You can also ask questions and provide feedback directly by using the Connectivity Link contact form or by emailing rhcl-contactus@redhat.com . 1.4. Connectivity Link supported platforms and components For details on the platform and component versions supported by Red Hat Connectivity Link 1.0, see the following article: Supported Configurations for Red Hat Connectivity Link . 1.5. Upgrading from Connectivity Link 1.0.0 to 1.0.1 You can upgrade from Connectivity Link 1.0.0 to Connectivity Link 1.0.1 by using the OperatorHub in the OpenShift web console. 1.5.1. Authenticating to registry.redhat.io for Wasm plug-in access For RateLimitPolicy or AuthPolicy only, you must authenticate to registry.redhat.io to access the Wasm plug-in image used with OpenShift Service Mesh as the Gateway API provider. Prerequisites You have credentials to access registry.redhat.io . If you do not have access, see Creating Registry Service Accounts . Procedure Create the following secret in your Gateway namespace: Repeat this step in each Gateway namespace in which a RateLimitPolicy or AuthPolicy is deployed. 1.5.2. Upgrading to Connectivity Link 1.0.1 in the web console Prerequisites You already have Connectivity Link 1.0.0 installed on OpenShift 4.16 or later. For RateLimitPolicy or AuthPolicy only, you have performed the steps in Section 1.5.1, "Authenticating to registry.redhat.io for Wasm plug-in access" . Procedure Click Operators > Installed Operators > Red Hat Connectivity Link . Ensure that Update channel is set to stable . If Update approval is set to Automatic , the upgrade will be approved and installed immediately when the Update channel is set to stable . If Update approval is set to Manual , click Install . Wait until the Connectivity Link Operator is deployed. Verify that Connectivity Link 1.0.1 is installed and that your deployment is up and running. After upgrade For RateLimitPolicy or AuthPolicy only, if you patched your subscription as a workaround for CONNLINK-299 , enter the following command to ensure that your environment is set correctly: Additional resources For more information, see Updating installed Operators . 1.6. Connectivity Link resolved issues Table 1.1. Resolved issues in Connectivity Link 1.0.1 Issue Description CONNLINK-299 Support protected container registry when loading wasm-shim image. Previously, for AuthPolicy and RateLimitPolicy, Connectivity Link did not support a protected container registry when the loading wasm-shim image. Now, Connectivity Link supports protected registries, and the steps to authenticate to registry.redhat.io are documented in Installing Connectivity Link on OpenShift . CONNLINK-309 Certificates not managed by Connectivity Link are deleted. Previously, certificates not managed by Connectivity Link were deleted, even when a TLSPolicy was not configured. Now, these certificates are no longer deleted. CONNLINK-313 Fix example commands for configuring DNS provider credentials. Previously, Installing Connectivity Link on OpenShift included incorrect example commands for configuring DNS provider credentials. Now, these examples have been fixed. CONNLINK-325 Duplication of configuring DNS provider secret. Previously, Installing Connectivity Link on OpenShift and Configuring and deploying Gateway policies with Connectivity Link both described how to configure the DNS provider secret. Now, the documentation has been updated to avoid duplication. CONNLINK-360 Topology: ConfigMap location lookup using wrong URI. Previously, in the OpenShift web console plug-in, the topology location lookup used the wrong URI. Now, the OpenShift console plug-in uses the correct URI. 1.7. Connectivity Link known issues The following known issues apply in Connectivity Link 1.0: Connectivity Link Operator CONNLINK-287 - Connectivity Link allows configuration for non-standard response codes Connectivity Link should not allow configuration that specifies non-standard custom HTTP response codes such as HTTP 333. OpenShift web console plug-in CONNLINK-289 - Namespace selector in Policies view switches from subnavigation item -level view In the Policies view, in a specific policy list, for example, DNS policies, when you switch namespace, you return to the All Policies view. Instead, you should switch namespace and stay in the original specific policy list. Supported platforms CONNLINK-301 - Connectivity Link is not available for Azure Red Hat OpenShift Connectivity Link is not yet available for Azure Red Hat OpenShift due to the lack of support for OpenShift Container Platform 4.16 or 4.17 in Azure. Connectivity Link support for Azure Red Hat OpenShift will be added when OpenShift 4.16 support is available in Azure. For more information, see What's new with Azure Red Hat OpenShift?
