In HashiCorp Nomad, is it possible to specify the bind port for a Server and Client (e.g., from 464{6,7,8} to 600{6,7.8}?

The addresses stanza does not allow port specification, and neither does the -bind switch. The advertise stanza does not change the port on which Nomad binds.

The -bind switch allows specifying IP only:

> nomad agent -server -data-dir=/tmp/nomad -bind=0.0.0.0
==> No configuration files loaded
==> Starting Nomad agent...
==> Nomad agent configuration:

       Advertise Addrs: HTTP: <HOSTIP>:4646; RPC: <HOSTIP>:4647; Serf: <HOSTIP>:4648
            Bind Addrs: HTTP: 0.0.0.0:4646; RPC: 0.0.0.0:4647; Serf: 0.0.0.0:4648

Attempting to specify a port errors out:

> nomad agent -server -data-dir=/tmp/nomad -bind=0.0.0.0:6000 
==> Failed to parse HTTP advertise address (, 0.0.0.0:6000, 4646, false): Error resolving bind address "0.0.0.0:6000": lookup 0.0.0.0:6000: no such host

    May I point out that Nomad questions usually live on SO? Source: https://stackexchange.com/search?q=nomad – Elle Fie Dec 20 '19 at 06:19

Use the ports stanza to select ports for the agent, whether in server or client mode.

you should look on hashicorp website how to launch nomad with server.hcl client.hcl and nomad.hcl file

:

echo 'server {
    enabled = true
    bootstrap_expect = 1
    
    }' > /etc/nomad.d/server.hcl
  
echo 'region     = "global"
    datacenter = "dc1"
    data_dir  = "/opt/nomad"
    bind_addr = "1.2.3.4" # the default

    advertise {
    # Defaults to the first private IP address.
    http = "1.2.3.4"
    rpc  = "1.2.3.4" #put your adresse here
    serf = "1.2.3.4:5648" # non-default ports may be specified
              }
    ' > /etc/nomad.d/nomad.hcl

and run this :

nomad agent -config /etc/nomad.d
