我可以像这样为每个实例启动Faxton:

http://127.0.0.1:5984/
http://127.0.0.1:15984/
http://127.0.0.1:25984/

现在,我尝试在主容器上设置复制,但是我必须弄乱复制目标的值。以下是我指定的值:

Replication Source:    Local Database
Source Name:   widgets
Replication Target:    New Remote Database
New Database: http://127.0.0.1:15984/widgets
Replication Type:  Continuous

原始配置JSON如下所示:

{
  "_id": "310ab1c7a68d4ae4aba039d2fa00320f",
  "_rev": "2-cf1a3abced5f09ceebd9d54f42ebd65d",
  "user_ctx": {
    "name": "couchdb",
    "roles": [
      "_admin",
      "_reader",
      "_writer"
    ]
  },
  "source": {
    "headers": {
      "Authorization": "Basic Y291Y2hkYjpwYXNzd29yZA=="
    },
    "url": "http://127.0.0.1:5984/widgets"
  },
  "target": {
    "headers": {
      "Authorization": "Basic Y291Y2hkYjpwYXNzd29yZA=="
    },
    "url": "http://127.0.0.1:15984/widgets"
  },
  "create_target": true,
  "continuous": true,
  "owner": "couchdb"
}

如有任何建议,我们将不胜感激。

我要补充的一点是,另外两个节点上还没有运行安装程序。意思是,我创建了集群,但是当我启动webapp时,它会提示我创建一个节点或一个集群。在复制工作之前,是否必须将每个节点设置为单个节点?

另外,我首先是这样创建集群/容器的: https://github.com/apache/couchdb-docker/issues/74 我用了那个码头工人-合成.yml文件。

就集群而言,使用运行在127.0.0.1:5984的fauxton,对于server-0,我添加了如下两个节点:

couchdb-2:5984绑定地址0.0.0.0

那么当我这样做时(注意端口):

 http://127.0.0.1:15984/_node/couchdb@couchdb-1/_config

我得到了一个合法的json响应,表明有东西以“couchdb-1”的名称运行。然而,我意识到我仍然在使用主机来获取couchdb-1服务器的视图。(服务器-1)

通过命令行,我确认我有这样的节点:

PS C:\Users\jj2>curl-X GET“ http://127.0.0.1:5984/_membership “--用户couchdb 输入用户“couchdb”的主机密码: {“所有节点”:[”couchdb@couchdb-0“],“群集节点”:[”couchdb@couchdb-0","couchdb@couchdb-1","couchdb@couchdb-2"]} PS C:\Users\jj2>

最后,我想也许我可以使用docker分配的容器的IP地址,但是没有一个可以从主机ping。它们都是172.x.x.x地址。

以防有帮助。
