Chapter 1. New and changed features
This release of Red Hat Application Interconnect is incompatible with all previous releases of AMQ Interconnect 2.0. To avoid disruption, you must upgrade all sites in your service network to this release using the following command:
$ skupper update
1.1. Network status command
Use the skupper network status command to display an overview of the service network.
1.2. Red Hat Application Interconnect policy system
You can apply a policy system to restrict access to the service network as described in Securing a service network using policies.
1.3. TLS support for services using the HTTP2 protocol
Use the --enable-tls option to secure HTTP2 traffic between a backend pod and the Application Interconnect router pod.
1.4. Gateways
Red Hat recommends removing any gateways before upgrading, and recreating those gateways after a successful upgrade.
With this release only one gateway is created per user/host. Previously, a user could create multiple gateways, this is no longer possible. If you require multiple gateways per host, create a new user for each gateway.
Port negotiation limitation
If your protocol negotiates the communication port, for example active FTP, you cannot use that protocol to communicate across a service network.
1.5. Known issues
SKUPPER-274 - Skupper link site not working when using FIREFOX due to a missing function
An error occurs if you try to link sites using the Firefox browser.
Workaround
Use the Chrome browser when creating links between sites using a browser.
SKUPPER-171 - Skupper policies don’t work on OCP 3.11
You cannot apply the policy CRD to an OpenShift version 3.11 cluster.
Workaround
Upgrade OpenShift to version 4.
