# Consul API Gateway 0.3.0
|
|
|
|
|

|
## Release Highlights
|
|
|
|
|
|
|
|
|
|
- **Improved High Availability and Scalability via Multiple Instances per Gateway:**
|
|
|
|
|
This release introduces support for deploying multiple instances of a logical
|
2022-06-21 14:42:52 +00:00
|
|
|
gateway (i.e. a K8s `gateway` config object). You can use an external load
|
2022-06-21 00:00:11 +00:00
|
|
|
balancing service to distribute incoming traffic across the instances of a
|
|
|
|
|
gateway. This provides higher availability of gateway services and also allows
|
|
|
|
|
a single logical gateway to handle a volume of network traffic that is much
|
|
|
|
|
greater than what a single instance of a gateway can.
|
|
|
|
|
|
|
|
|
|
Administrators can set the number of instances independently for each logical
|
|
|
|
|
gateway. Administrators can also set, in the `gatewayClassConfig`, the
|
|
|
|
|
minimum, maximum and default number of gateway instances. These are applied
|
|
|
|
|
per `gateway` to all `gateways` in that `gatewayClass`. The minimum and
|
2022-06-21 15:37:19 +00:00
|
|
|
maximum settings will override settings configured on any given `gateway`.

|
|
|
|
2022-06-21 23:24:19 +00:00
|
|
|
~> **Note:** There is a hard limit of eight (8) instances per `gateway` and it can
|
2022-06-21 00:00:11 +00:00
|
|
|
not be overridden. This hard limit will probably be increased in the future.
|
|
|
|
|
|
|
|
|
|
- **Cross Namespace Reference Policies for Certificates:**
|
|
|
|
|
Reference policies is a security feature introduced in the 0.2 release. In
|
|
|
|
|
this release, Reference Policies are now required for TLS certificates when a
|
2022-06-21 15:37:19 +00:00
|
|
|
`listener` has a `certificateRef` that is in a different `namespace`.
