How to specify unicast.hosts from environment variable?


(Attila Nagy) #1

Hi,

I would like to specify the master list via an environment variable, like this:
network.bind_host: ["${ES_HOST}","127.0.0.1"]
(this works)

What I try is the following:
export ES_MASTER_PORT=$((9300+$ES_MASTER_OFFSET))
export ES_MASTERS="["10.6.145.219:${ES_MASTER_PORT}","10.6.145.220:${ES_MASTER_PORT}","10.6.145.221:${ES_MASTER_PORT}"]"

And this in elasticsearch.yml:
discovery.zen.ping.unicast.hosts: "${ES_MASTERS}"

What I get is this:
Exception in thread "main" java.lang.IllegalArgumentException: Failed to resolve address for [["10.6.145.219:9300"]
Likely root cause: java.lang.IllegalArgumentException: Invalid bracketed host/port range: ["10.6.145.219:9300"

Is it possible to achieve this somehow?
