CloudFoundry中的CouchDB？ [英] CouchDB in CloudFoundry?
问题描述
我查看了Cloud Foundry项目，并尝试将其安装在服务器上
我将Couchdb用作数据库服务。
我的主要问题是：如何在Cloud Foundry中使用CouchDB？
我使用以下命令安装CF实例：vcap_dev_setup -c devbox_all.yml -D mydomain.com
devbox.yml包含：
$ install：
-全部。
在此安装中，默认情况下，该属性是ouchdb_node和该couchdb_gateway的存在。
但这似乎通常是错误。
删除应用程序时出现此错误，例如：
$ vmc delete notes2
已配置检测到服务[mongodb-d216a]，要删除它吗？ [yN]：是
检测到预配置服务[redis-8fcdc]，您要删除该服务吗？ [yN]：y
删除应用程序[notes2]：确定
删除服务[mongodb-d216a]：错误503：服务网关
因此，我尝试使用此配置安装CF实例。
（带有redis，couch和mongo的标准单节点）
conf.yml：
$作业：
安装：
-nats_server
-路由器
-暂存器
-ccdb
-cloud_controller：
Builtin_services：
-redis
-mongodb
-长沙发
-health_manager
-dea
-uaa
-uaadb
-redis_node：
索引： 0
-benchdb_node：
索引： 0
-mongodb_node：
索引： 0
-coudb_gateway
-redis_gateway
-mongodb_gateway
首先，此配置不有效，因为选项'couchdb'不是有用的关键字（在内置服务中如此）
那么，我做错了什么？
是否正在集成沙发，并且上周还没有完成？
要继续，我成功地安装了没有长沙发内置服务的CF实例选项，但有一个ouchdb_node和一个ouchdb_gateway。他们开始了。
我想该服务是可运行的。
但是我无法在我的应用manifest.yml中使用 couchdb或选择绑定此服务。
（这似乎很正常，因为它不是作为服务安装的）
因此，它似乎已经可以使用了，但是不是。
我在这里寻求有关此主题的建议，因为我没有找到在网上谈论话题的人。
感谢阅读我。
卢卡斯解决方案我决定亲自尝试一下，看来效果不错。我用vcap_dev_setup和以下配置创建了一个新的VCAP实例。

-mysql

-长沙发网关
-长沙发节点：$ b $ b索引： 0

我能够绑定CouchDB实例到节点应用程序，并从VCAP_SERVICES读取服务信息，如下所示；
'{ couchdb-1.2：[{名称： couchdb-c7eb，标签： couchdb-1.2，计划：免费，标签：[键值，缓存， couchdb-1.2， couchdb ]，凭据：{主机名： 127.0.0.1，主机： 127.0.0.1，端口：5984，用户名： 7f3c0567-89cc-4240-b249-40d1f4586035， password： 8fef9e88-3df2-46a8-a22c-db02b2917251， name： dde98c69f-01e9-4e97-b0d6-43bed946da95}}}}''
我还能够将服务隧道传输到本地端口并连接到该端口，您可以在此图像中看到
什么版本的Ubuntu您曾经安装过VCAP吗？
I review the Cloud Foundry project and try to install it on a server
I will use Couchdb as a database service.
My principal question is : How use CouchDB in Cloud Foundry?
I install a CF instance with : vcap_dev_setup -c devbox_all.yml -D mydomain.com
The devbox.yml contains :
$ install : - all.In this install the couchdb_node and the couchdb_gateway is present by default. But it seems to be bug in general. When I delete a app and I have this error for example :
$ vmc delete notes2 Provisioned service [mongodb-d216a] detected, would you like to delete it? [yN]: y Provisioned service [redis-8fcdc] detected, would you like to delete it? [yN]: y Deleting application [notes2]: OK Deleting service [mongodb-d216a]: Error 503: Unexpected response from service gatewaySo I tried to install a CF instance with this config. (A standard single-node with redis, couch and mongo)
conf.yml :
$ jobs: install: - nats_server - router - stager - ccdb - cloud_controller: builtin_services: - redis - mongodb - couchdb - health_manager - dea - uaa - uaadb - redis_node: index: "0" - couchdb_node: index: "0" - mongodb_node: index: "0" - coudb_gateway - redis_gateway - mongodb_gatewayFirst, this config doesn't work, because the option 'couchdb' is not a valable keyword (In the part built-in services)
So, what I do wrong? Is in the way to integrate couch and it's not finished last week ?
To continue, I success to install the CF instance without the couchdb built-in services option but with a couchdb_node, and a couchdb_gateway. And they start. I suppose the service is runnable.
But i can't use 'couchdb' in my app manifest.yml or choose this service to bind on. (It's seems normal because it's not install as a service)
So, It seems to be close to work, but it's not.
I resquest Ideas, Advice on this subject here because I didn't find people talking about around the web.
Thank's to read me. Lucas
解决方案I decided to try this myself and it appears to work OK. I created a new VCAP instance with vcap_dev_setup and the following configuration ..
--- deployment: name: "cloudfoundry" jobs: install: - nats_server - cloud_controller: builtin_services: - mysql - postgresql - couchdb - stager - router - health_manager - uaa - uaadb - ccdb - dea - couchdb_gateway - couchdb_node: index: "0" - postgresql_gateway - postgresql_node: index: "0" - mysql_gateway - mysql_node: index: "0"I was able to bind instances of CouchDB to a node app and read the service info from VCAP_SERVICES, as below;
'{"couchdb-1.2":[{"name":"couchdb-c7eb","label":"couchdb-1.2","plan":"free","tags":["key-value","cache","couchdb-1.2","couchdb"],"credentials":{"hostname":"127.0.0.1","host":"127.0.0.1","port":5984,"username":"7f3c0567-89cc-4240-b249-40d1f4586035","password":"8fef9e88-3df2-46a8-a22c-db02b2917251","name":"dde98c69f-01e9-4e97-b0d6-43bed946da95"}}]}'I was also able to tunnel the service to a local port and connect to it which you can see in this image
What version of Ubuntu have you used to install VCAP?
