[jayhendren]

Cookbook version

7.0.0

Chef-client version

14.13.11

Platform Details

RHEL 7

Scenario:

Creating a slave using the jenkins_ssh_slave resource

Steps to Reproduce:

Install ssh-slaves plugin 1.30.2 and use jenkins_ssh_slave to create a slave.

I get no errors with ssh-slaves plugin 1.28.1. I haven't tested any intermediate versions of the plugin.

Expected Result:

Slave created without errors.

Actual Result:

* jenkins_ssh_slave[local_executor_1.example.com] action create
  
  ================================================================================
  Error executing action `create` on resource 'jenkins_ssh_slave[local_executor_1.example.com]'

I'm getting the same error under ssh slaves plugin 1.31.0. I downgraded to 1.28.1 reran chef job and everything is working.

[djessich]

I have the same problem with version 1.31.0.

Browsing the ssh-slaves plugin source on Github (class SSHLauncher), I can confirm that since version 1.30.0 of the plugin the following Constructor (which was deprecated) has been removed. This Constructor will be used from the Groovy script of jenkins_ssh_slave resource.

@Deprecated
public SSHLauncher(String host, int port, String credentialsId, String jvmOptions, String javaPath, String prefixStartSlaveCmd, String suffixStartSlaveCmd, Integer launchTimeoutSeconds, Integer maxNumRetries, Integer retryWaitTime) { ... }

However the new Constructor since version 1.30.0 reads as follows:

public SSHLauncher(@NonNull String host, int port, String credentialsId, String jvmOptions, String javaPath, String prefixStartSlaveCmd, String suffixStartSlaveCmd, Integer launchTimeoutSeconds, Integer maxNumRetries, Integer retryWaitTime, SshHostKeyVerificationStrategy sshHostKeyVerificationStrategy) { ... }

Meaning, that jenkins_ssh_slave resource should add the SshHostKeyVerificationStrategy in its groovy script, to solve the problem.

Therefore the latest working plugin version for me is 1.29.4.

Also, you can look in #589 that issue has examples for working around this if you fork this cookbook.
