我正在编写一个自动Jenkins机器创建脚本,我遇到了SSH凭据的问题,即:
在Jenkins中有一个名为credentials.xml
的文件(在/var/lib/jenkins
中),它存储了节点的凭据。我看起来像这样:
<?xml version='1.0' encoding='UTF-8'?>
<com.cloudbees.plugins.credentials.SystemCredentialsProvider plugin="credentials@1.18">
<domainCredentialsMap class="hudson.util.CopyOnWriteMap$Hash">
<entry>
<com.cloudbees.plugins.credentials.domains.Domain>
<specifications/>
</com.cloudbees.plugins.credentials.domains.Domain>
<java.util.concurrent.CopyOnWriteArrayList>
<com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl>
<scope>GLOBAL</scope>
<id>8743cc14-bc2c-44a6-b6bb-c121bef4ae2d</id>
<description>root_with_secret</description>
<username>root</username>
<password>2Xd4i7+8tjVXg2RHP6ggl/ZtWJp177ajXNajJxsj80o=</password>
</com.cloudbees.plugins.credentials.impl.UsernamePasswordCredentialsImpl>
</java.util.concurrent.CopyOnWriteArrayList>
</entry>
</domainCredentialsMap>
还有节点(从节点)配置文件(存储在/var/lib/jenkins/nodes/HOSTNAME/config.xml
中为每个从节点),它们看起来像:
<?xml version='1.0' encoding='UTF-8'?>
<slave>
<name>HOSTNAME_OF_MY_SECRET_MACHINE</name>
<description>HOSTNAME_OF_MY_SECRET_MACHINE</description>
<remoteFS>/root</remoteFS>
<numExecutors>1</numExecutors>
<mode>NORMAL</mode>
<retentionStrategy class="hudson.slaves.RetentionStrategy$Always"/>
<launcher class="hudson.plugins.sshslaves.SSHLauncher" plugin="ssh-slaves@1.9">
<host>10.0.10.1</host>
<port>22</port>
<credentialsId>8743cc14-bc2c-44a6-b6bb-c121bef4ae2d</credentialsId>
<maxNumRetries>0</maxNumRetries>
<retryWaitTime>0</retryWaitTime>
</launcher>
<label></label>
<nodeProperties/>
<userId>anonymous</userId>
</slave>
问题在于,在创建jenkins机器后,为每个从属设备复制credentials.xml
和config.xml
,然后凭据将无法正常工作。我得到了

要解决此问题,我可以访问 Jenkins - &gt; 凭证 - &gt;然后使用我将使用的相同密码更新凭证,它将起作用。
所以问题是Jenkins是否每次安装都使用salting / hashing,以便credentials.xml
在复制到新机器时不起作用?
答案 0 :(得分:6)
好的,我已经设法用(我相信)一个解决方法来解决这个问题,即:
要在credentials.xml
中以纯文本格式存储密码,请在安装和启动服务后将其复制到Jenkins计算机上。然后詹金斯将用它的新秘密(或者它用于此目的的任何东西)加密它并且它将起作用:)
修改强>
第二个选项是安装Jenkins,启动它,然后将credentials.xml
与加密密码一起复制到secrets
目录和secret.xml
之前的安装。这将复制加密主密钥和使用此主密钥创建的加密凭据。
