* First cluster grpc service should be NodePort This is based on the issue opened here https://github.com/hashicorp/consul-k8s/issues/1903 If you follow the documentation https://developer.hashicorp.com/consul/docs/k8s/deployment-configurations/single-dc-multi-k8s exactly as it is, the first cluster will only create the consul UI service on NodePort but not the rest of the services (including for grpc). By default, from the helm chart, they are created as headless services by setting clusterIP None. This will cause an issue for the second cluster to discover consul server on the first cluster over gRPC as it cannot simply cannot through gRPC default port 8502 and it ends up in an error as shown in the issue https://github.com/hashicorp/consul-k8s/issues/1903 As a solution, the grpc service should be exposed using NodePort (or LoadBalancer). I added those changes required in both cluster1-values.yaml and cluster2-values.yaml, and also a description for those changes for the normal users to understand. Kindly review and I hope this PR will be accepted. * Update website/content/docs/k8s/deployment-configurations/single-dc-multi-k8s.mdx Co-authored-by: trujillo-adam <47586768+trujillo-adam@users.noreply.github.com> * Update website/content/docs/k8s/deployment-configurations/single-dc-multi-k8s.mdx Co-authored-by: trujillo-adam <47586768+trujillo-adam@users.noreply.github.com> * Update website/content/docs/k8s/deployment-configurations/single-dc-multi-k8s.mdx Co-authored-by: trujillo-adam <47586768+trujillo-adam@users.noreply.github.com> --------- Co-authored-by: trujillo-adam <47586768+trujillo-adam@users.noreply.github.com> |

Consul
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh - Consul Service Mesh enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections with Transparent Proxy.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, macOS, FreeBSD, Solaris, and Windows and includes an optional browser based UI. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
