Enterprise Search cannot connect to Kibana on startup

Hi everyone,

I'm currently trying to setup Enterprise Search through Docker compose using this guide (Running Enterprise Search using Docker | Elastic Enterprise Search Documentation [8.3] | Elastic)

So far, the ES and Kibana containers can startup correctly and are healthy but for some reason, when the Enterprise Search one tries, it can not connect to Kibana backend even though is it started and healthy. Here are a snippet of the logs :

It then exits with code 137.

.env and docker-compose.yml file have not been touched except to set the passwords, they were straight copied/pasted from the official guide.

Hi @Emeto , welcome to the community!

Not being able to connect to Kibana shouldn't be a stopper for Enterprise Search to start. I've just tested the original docker-compose instructions and work fine for me.

Can you upload the whole Enterprise Search log so we can understand what went wrong?
