How to configure the publish address of elasticsearch 5.0 with CLI flags

Elastic Stack Elasticsearch
1

I've used elasticsearch 2.0 with start up flags to configure the publish_addres. I need the publish address to be configured, because I want to start elasticsearch in a docker container and access it from outside. So the publish address must be the IP of the docker host, which is in my case 192.168.99.100. I want to access elasticsearch on port 9201.

docker run -d -p 9201:9201 --name elasticsearch_test elasticsearch:5.2-alpine elasticsearch -Enetwork.publish_host="192.168.99.100" -Ehttp.port="9201"

which is like the old command

docker run -d -p 9201:9201 --name elasticsearch_test elasticsearch:2.4.1 elasticsearch -Des.network.publish_host="192.168.99.100" -Des.http.port="9201"

But when I start the container and look into the logs I don't get the publish address 192.168.99.100:9201, but 192.168.99.100:9300 and 172.17.0.2:9201. How can I force elasticsearch to use my combination of address and port?

Thanks in advance

Hi,

Can you try and set transport.tcp.port and/or transport.publish_port and transport.publish_host. And see if this has any effect.

Thank you very much. That made it. I had to change http.port to transport.publish_port

The following command works as expected

docker run -d -p 9201:9201 --name elasticsearch_test elasticsearch:5.2-alpine elasticsearch -Enetwork.publish_host="192.168.99.100" -Etransport.publish_port="9201"
