使用puppet初始化Couchbase

Question

我设置了一个运行我的Couchbase DB的流浪汉机器。当创建盒子时，我想用puppet初始化我的Couchbase。当我运行以下命令(在Couchbase集群中)时，它可以工作。

vagrant@precise64:~$ /opt/couchbase/bin/couchbase-cli  cluster-init --cluster=localhost --cluster-init-username=Administrator --cluster-init-password=foobar --cluster-init-ramsize=256 -u Administrator -p foobar -d
INFO: running command: cluster-init 
INFO: servers {'add': {}, 'failover': {}, 'remove': {}}
METHOD: POST
PARAMS:  {'username': 'Administrator', 'password': 'foobar', 'port': 'SAME', 'initStatus': 'done'}
ENCODED_PARAMS: username=Administrator&password=foobar&port=SAME&initStatus=done
REST CMD: POST /settings/web
response.status: 200
METHOD: POST
PARAMS:  {'memoryQuota': '256'}
ENCODED_PARAMS: memoryQuota=256
REST CMD: POST /pools/default
response.status: 200
SUCCESS: init localhost
$ vagrant@precise64:~$ echo $?
0

但是，当我通过puppet运行相同的命令时，puppet抱怨返回值为非零。

vagrant@precise64:~$ puppet apply --debug -e 'exec { "couchbase-init-cluster": command => "/opt/couchbase/bin/couchbase-cli  cluster-init --cluster=localhost --cluster-init-username=administrator --cluster-init-password=foobar --cluster-init-ramsize=256 -u administrator -p foobar"}'

请告诉我怎么用木偶来运行这个命令。

Answer 1

我相信puppet apply -e采用的是傀儡表达式，而不是任意的外壳表达式。你可能想要这样的东西：

puppet apply -e 'exec { "couchbase-init": \
    command => "/opt/couchbase/bin/couchbase-cli cluster-init <rest of options>"'
