v0.21.0

FEATURES

• Add experimental support for multi-datacenter federation via

  global:
    federation:
      enabled: true

  This requires Consul 1.8.0+ (which as of this release is only available as
  a beta. To use the beta, set global.image: consul:1.8.0-beta1)

• Add new Helm value global.federation.createFederationSecret that will
  create a Kubernetes secret in primary datacenters that can be exported to secondary
  datacenters to help bootstrap secondary clusters for federation (GH-447).

IMPROVEMENTS

• Default Consul Docker image is now consul:1.7.3.
• Default consul-k8s Docker image is now hashicorp/consul-k8s:0.15.0.
• ACLs: Restrict permissions for the server-acl-init job [GH-454].

BUG FIXES

• Fix missing NODE_NAME environment variable when setting meshGateway.wanAddress.source=NodeName
  [GH-453].
