v1.0.0-beta1

1.0.0-beta1 (October 4, 2022)

FEATURES:

• CLI:
  • Add the ability to install HCP self-managed clusters. [GH-1540]
  • Add the ability to install the HashiCups demo application via the -demo flag. [GH-1540]

BREAKING CHANGES:

• Consul client agents are no longer deployed by default, and Consul service mesh no longer uses Consul clients to operate. This change affects several main areas listed below. [GH-1552]
  • Control plane:
    • A new component consul-dataplane is now injected as a sidecar-proxy instead of plain Envoy. consul-dataplane manages the Envoy proxy process and proxies xDS requests from Envoy to Consul servers.
    • All services on the service mesh are now registered directly with the central catalog in Consul servers.
    • All service-mesh consul-k8s components are configured to talk directly to Consul servers.
    • Mesh, ingress, and terminating gateways are now registered centrally by the endpoints controller, similar to how service-mesh services are registered.
  • Helm:
    • client.enabled now defaults to false. Setting it to true will deploy client agents, however, none of the consul-k8s components will use clients for their operation.
    • global.imageEnvoy is no longer used for sidecar proxies, as well as mesh, terminating, and ingress gateways.
    • externalServers.grpcPort default is now 8502 instead of 8503.
    • meshGateway.service.enabled value is removed. Mesh gateways now will always have a Kubernetes service as this is required to register them as a service with Consul.
    • meshGateway.initCopyConsulContainer, ingressGateways.initCopyConsulContainer, terminatingGateways.initCopyConsulContainer values are removed.
  • Known beta limitations:
    • Transparent proxy is not yet supported.
    • Metrics and observability is not yet supported.
    • API gateway is not yet supported.
    • Executables in the form of exec= are not yet supported when using external servers and ACLs.
