搬运工，撰写副本主机

Question

我试图添加集群使用docker-compose scale graylog-es-slave=2副本但对于第3版Dockerfile不像Docker compose and hostname

我所试图做的九弄清楚如何获得特定节点的副本集

这是我曾尝试

D:\p\liberty-docker>docker exec 706814bf33b2 ping graylog-es-slave -c 2 
PING graylog-es-slave (172.19.0.4): 56 data bytes 
64 bytes from 172.19.0.4: icmp_seq=0 ttl=64 time=0.067 ms 
64 bytes from 172.19.0.4: icmp_seq=1 ttl=64 time=0.104 ms 
--- graylog-es-slave ping statistics --- 
2 packets transmitted, 2 packets received, 0% packet loss 
round-trip min/avg/max/stddev = 0.067/0.085/0.104/0.000 ms 

D:\p\liberty-docker>docker exec 706814bf33b2 ping graylog-es-slave.1 -c 2 
ping: unknown host 

D:\p\liberty-docker>docker exec 706814bf33b2 ping graylog-es-slave_1 -c 2 
ping: unknown host 

的docker-compose.yml

version: 3 
service: 
    graylog-es-slave: 
    image: elasticsearch:2 
    command: "elasticsearch -Des.cluster.name='graylog'" 
    environment: 
     ES_HEAP_SIZE: 2g 
    deploy: 
     replicas: 2 <-- this is ignored on docker-compose just putting it here for completeness

相反的.，使用_（下划线），并添加项目名称的前缀（包含您的码头工人，compose.yml的目录，我认为它是liberty-docker_graylog）：

ping liberty-docker_graylog-es-slave_1 

你可以看到这样做network ls，搜索正确的网络，然后docker network inspect network_id。
