HOWTO detect when JBOSS is fully up and running and ready to accept deployments?

Question

I have a simple "sanity-check" webapp that I wish to deploy on a JBoss EAP server as soon as it is started. But what does "started" mean? If my script that calls the jboss cli is launched too soon after JBoss reports it's done, I get a message saying

  {"WFLYDC0074: Operation failed or was rolled back on all servers. Server failures:" => {"server-group" => {"main-server-group" => {"host" => {"master" => {"master-1-server-1" => "WFLYCTL0379: System boot is in process; execution of remote management operations is not currently available"}}}}}}

How can I detect that JBoss is really ready to handle deployments?

Alternatively, is there a mechanism by which I can autodeploy something on startup?

#!/bin/bash

while true
  do
    wildflyStarted=$(grep -ic "Wildfly.*started in.*ms.*Started.*of.*services" /opt/wildfly/standalone/log/server.log)
    if [[ "$wildflyStarted" -eq "1" ]]; then
      break;
    else
      sleep 1;
    fi
  done

while true
  do
    ejbcaStatus=$(/opt/wildfly/bin/jboss-cli.sh -c --commands="cd deployment,cd ejbca.ear,read-attribute status")
    if [[ "$ejbcaStatus" -eq "OK" ]]; then
      break;
    else
      sleep 5;
    fi
  done

This script worked for me.
