Graylog docker, no route to host

So basically I set up graylog with docker, documents - quick start with

-p 9000:9000 -p 12201:12201 -p 1514:1514 -p 5555:5555

and I’m able to send some msgs.


However, when I try to retrieve msgs, I encountered:

While retrieving data for this widget, the following error(s) occurred:
No route to host (Host unreachable).

in search tab under both Message Count and All Messages widget

Am I missing something ?

Does you elastic container runing well?
Does the GL container can access to the elastic container?



max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]


sudo sysctl -w vm.max_map_count=262144
