git clone https://github.com/anubhavmishra/envoy-consul-sds.git

Deploy Envoy Consul Service Discovery Service

cd envoy-consul-sds

nomad plan jobs/envoy-consul-sds.nomad

+ Job: "envoy-consul-sds"
+ Task Group: "webserver" (1 create)
  + Task: "envoy-consul-sds" (forces create)
Scheduler dry-run:
- All tasks successfully allocated.
Job Modify Index: 0
To submit the job with version verification run:
nomad run -check-index 0 jobs/envoy-consul-sds.nomad
When running the job with the check-index flag, the job will only be run if the
server side version matches the job modify index returned. If the index has
changed, another user has modified the job and the plan's results are
potentially invalid.

nomad run jobs/envoy-consul-sds.nomad

Check if the service job is up and running
