I used docker-compose build a es cluster and reference official documents。 link:Install Elasticsearch with Docker | Elasticsearch Guide [8.11] | Elastic
I found that each of the docker-container Ip are automatically generated, and we are in the same network, we can't connect es cluster, I would like to ask this is because I configuration wrong?
docker-compose.yml 设置:
version: '2'

es_balance:
