            Traefik supports integrating with Consul through its Consul Catalog provider. See https://learn.hashicorp.com/tutorials/nomad/load-balancing-traefik for an example of how to configure this when running Traefik on Nomad.

            The example in that tutorial configures the tag traefik.http.routers.http.rule=Path('/myapp') on the service so that requests for /myapp are routed to the backend service instance. In your case, you'll need to modify this to match on the HTTP Host header so that you can route subdomains to different services. For example:

            Finally found it. Nomad has an option to expose a particular endpoint via sidecar proxy without mTLS authentication. The use case of this option is specifically for health check or metrics.

            https://www.nomadproject.io/docs/job-specification/expose#expose-examples

            The expose stanza inside connect stanza helps to achieve this.

            consul health check (All service checks failing)
            Asked 2021-Nov-04 at 19:11

            I have read the similar question related to this problem. It ended up with frustration.

            1. I installed consul with docker. I run the following command. docker run --name consul -d -p 8500:8500 consul, then I tested if the registration of service works using postman PUT method, but didn't enable health check, the service register into consul successfully in the consul web UI. For now everything works as expected.
            2. I have a local GRPC service written in go. The local service address is 127.0.0.1:8880. The address of consul server is 127.0.0.1:8500. Then the service is registered into consul, but health check didn't work, gets All service failing. Then I tried following:
              1. Use local IP address which is 192.168.0.152:8500 as address of consul server and 192.168.0.152:8880 as address of gprc service. Not working.
              1. Use local IP address which is 192.168.0.152:8500 as address of consul server and 127.0.0.1:8880 as address of gprc service. Not working.
              1. Check if HTTP service works. There is a local web service written in GIN. The port is 1010. AgentServiceCheck is following. Tried method above. Not working.

            Based on the documentation of the Consul API (https://www.consul.io/api-docs/agent/check#grpc), it seems that the GRPC field that you're using

            supports the standard gRPC health checking protocol.

            Therefore, you only need to define the gRPC endpoint there, and the protocol will handle the health checks.

            You can opt-out from this to use an HTTP endpoint for health checks by defining the HTTP field in your Agent Service Check config. You can find more information about that in the documentation (https://www.consul.io/api-docs/agent/check#http)

            You must have exactly the same encrypt settings on both types of node: server and client. Or, you must have encryption disabled everywhere. You can consult the official tutorial of step-by-step enabling encryption on the existing cluster.

            Authentication is null Micronaut 3

            I have a Micronaut 3 application, while using the JWT token the Authentication attribute on check method is null, however, I need to get all the roles from the JWT.

            As per latest change from Micronaut

            The SecurityRule API has changed. The last argument to the method was a map that represented the user attributes. Instead that argument was replaced with a reference to the Authentication. This has the benefit of rules now having access to the username of the logged in user as well as access to the convenience method getRoles().

            How to implement role-based auth with SPIFFE/SPIRE?
            Asked 2021-Sep-24 at 00:45

            I'm in the process of vetting a move to service mesh. While Istio and Consul Connect are certainly still in the cards, I'm leaning towards building up from a bit lower level with Linkerd and SPIFFE/SPIRE.

            I want to build a 'hello world' mesh to test this architecture out. In this hello world mesh, I'd like to be able to issue certificates from SPIFFE/SPIRE that encode some kind of role. As you can probably tell, I'm new to service meshes. How would I implement roles? Are there any guides out there to help get me started?

            So there isn't any kind of integration with Linkerd and SPIFFE/SPIRE. As of right now there isn't any particular plan for an integration but you can see the existing issue for more details. The next release of Linkerd, 2.11, will include the ability to create server side policy but current versions don't enforce any kind of policy settings.

            Install 2 Consul's client agents (separated clusters) on the same host
            Asked 2021-Sep-21 at 06:10

            I have 2 different HashiCorp Consul clusters (lets call them cluster A and cluster B) running on different hosts.

            My Python app is running on a host which I already installed on 1 client agent configured to cluster A and I want my app will be able to send requests to cluster B also (somehow distinguish between the 2 agents)

            Is it possible to install a second client agent (configured to cluster B) on that same host? and if so, how it can be done? Will I just need to change to a different port? Can't find documentation for that use case.

            You need to use a Helm chart that is compatible with the version of Consul you are installing. The last supported Helm chart version which is compatible with Consul 1.7.2 is version 0.21.0. See the compatibility matrix for Consul and Consul on Kubernetes at https://www.consul.io/docs/k8s/upgrade/compatibility for more info.

            You should be able to successfully install Consul by using the following Helm install command.
