搬運工，撰寫副本主機

Question

我試圖添加集羣使用docker-compose scale graylog-es-slave=2副本但對於第3版Dockerfile不像Docker compose and hostname

我所試圖做的九弄清楚如何獲得特定節點的副本集

這是我曾嘗試

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_（下劃線），並添加項目名稱的前綴（包含您的碼頭工人，compose.yml的目錄，我認爲它是liberty-docker_graylog）：

ping liberty-docker_graylog-es-slave_1 

你可以看到這樣做network ls，搜索正確的網絡，然後docker network inspect network_id。
