Consul client on Windows cannot find server nodes on AWS #8865

Closed marcofiocco closed 4 years ago

marcofiocco commented 4 years ago

Overview of the Issue

I have created a cluster on AWS using https://github.com/hashicorp/nomad-autoscaler. The Ubuntu server and client nodes work fine, they can find each other. Now I have a Windows 2016 instance on AWS (in the same subnet of a Linux client), where I have installed nomad and consul. Nomad should join the servers thanks to Consul using auto join as the Linux clients do, but it does not work in this Windows instance. Note that I’ve tagged the AWS instance with ConsulAutoJoin = auto-join already.

Reproduction Steps

The Consul HCL is (using the IP is the Windows instance):

datacenter = "dc1"
data_dir = "C:\\Consul\\data"
advertise_addr = "10.241.238.196"
bind_addr = "0.0.0.0"
client_addr = "0.0.0.0"
log_level = "INFO"
retry_join = ["provider=aws tag_key=ConsulAutoJoin tag_value=auto-join"]
ui = true

Consul info for both Client and Server

Client info ``` agent: check_monitors = 0 check_ttls = 0 checks = 1 services = 1 build: prerelease = revision = 12b16df3 version = 1.8.4 consul: acl = disabled known_servers = 0 server = false runtime: arch = amd64 cpu_count = 4 goroutines = 51 max_procs = 4 os = windows version = go1.14.6 serf_lan: coordinate_resets = 0 encrypted = false event_queue = 0 event_time = 1 failed = 0 health_score = 0 intent_queue = 0 left = 0 member_time = 2 members = 1 query_queue = 0 query_time = 1 ```
