设置CrateDB 4.0.4集群

Question

我正在尝试建立一个CrateDB 4.0.4社区集群，其中有3个节点在Docker中。

更新：

最后，我得到了4.0.4机箱中的集群。它只对我适用于Cnode.name属性。通过使用Hostname集群没有出现。

crate01:
  image: crate
  container_name: crate01
  hostname: crate01
  ports:
    - 4201:4200
  volumes:
    - /tmp/crate/01:/data
  command: >
    crate -Cnetwork.host=_site_
    -Cnode.name=crate01
    -Cdiscovery.seed_hosts=crate02,crate03
    -Ccluster.initial_master_nodes=crate01,crate02,crate03
  environment:
    - CRATE_HEAP_SIZE=2g
crate02:
  image: crate
  container_name: crate02
  hostname: crate02
  ports:
    - 4202:4200
  volumes:
    - /tmp/crate/02:/data
  command: >
    crate -Cnetwork.host=_site_
    -Cnode.name=crate02
   -Cdiscovery.seed_hosts=crate01,crate03
    -Ccluster.initial_master_nodes=crate01,crate02,crate03
  environment:
    - CRATE_HEAP_SIZE=2g

crate03:
  image: crate
  container_name: crate03
  hostname: crate03
  ports:
    - 4203:4200
  volumes:
    - /tmp/crate/03:/data
  command: >
    crate -Cnetwork.host=_site_
    -Cnode.name=crate03
    -Cdiscovery.seed_hosts=crate01,crate02
    -Ccluster.initial_master_nodes=crate01,crate02,crate03
  environment:
    - CRATE_HEAP_SIZE=2g

请尝试以下docker-compose.yml内容

crate01:
  image: crate
  container_name: crate01
  hostname: crate01
  ports:
    - 4201:4200
  net: crate
  command: >
    crate -Cnetwork.host=_site_
    -Cdiscovery.seed_hosts=crate02,crate03
    -Ccluster.initial_master_nodes=crate01,crate02,crate03
  environment:
    - CRATE_HEAP_SIZE=2g

crate02:
  image: crate
  container_name: crate02
  hostname: crate02
  ports:
    - 4202:4200
  net: crate
  command: >
    crate -Cnetwork.host=_site_
    -Cdiscovery.seed_hosts=crate01,crate03
    -Ccluster.initial_master_nodes=crate01,crate02,crate03
  environment:
    - CRATE_HEAP_SIZE=2g

crate03:
  image: crate
  container_name: crate03
  hostname: crate03
  ports:
    - 4203:4200
  net: crate
  command: >
    crate -Cnetwork.host=_site_
    -Cdiscovery.seed_hosts=crate01,crate02
    -Ccluster.initial_master_nodes=crate01,crate02,crate03
  environment:
    - CRATE_HEAP_SIZE=2g
