Re: variable within a variable

2020-10-26 Thread cw

thank you for the suggestion and the explanation.  I'm definitely learning 
here.  slowly, but hopefully learning.

I'm also investigating just writing a quick python program that does the 
work for me and calling that to get the result I need.

Re: variable within a variable

2020-10-26 Thread jeremy mordkoff

okay, take this with a grain of salt because this is purely a guess

The ssh call is trying to serialize all of the local variables, but it 
can't serialize the simpleTemplate. So move all the code that touches 
simpletemplate into a function that's wrapped with the @NONCPS decorator. 

something like  this (I am writing this off the top of my head ... no 
verification)

@NONCPS
def make_path(MAL) { 

def pathname = "/srv/\${host}/foo/bar"
def templateMessage = new 
SimpleTemplateEngine().createTemplate(pathname)
def template = { host -> templateMessage.make(host: host)}
def result = template(MAL)
   return result
}

I wondered about that also, but I commented it out and still got the

 I looked at the link you sent but didn't really understand "using a

 but it still didn't expand:

 def fp = { filepath -> "${filepath}" }

Are you running this in the main thread of the enkinsFile itself or in a 
function? I suspect that you are in a function and you may need to use the 
@NONCPS decorator

Re: variable within a variable

2020-10-23 Thread cw

That's great, thank you very much.  I was able to take your code, 
substitute MAL for HOST, for instance, and test it in a groovy web console, 
and it returned the correct value and interpolated the variable even though 
the variable wasn't defined until after the pathname was defined with the 
variable in it.  Exactly what I was looking for.  However...

I took the same code and pasted it into my test jenkins pipeline and now 
I'm getting an error on a subsequent command which I looked up, but I think 
it may be over my head...  Note that I'm getting the correct result with my 
substituted variable, but I'm just printing to the console and I'm not 
using it yet in the sshcommand, and yet sshcommand appears to be failing 
where before it wasn't.

I think you need to do an "eval" or the equivalent to filepath in order to 
expand the inner variable. I believe the ssh command is executing "ls 
/srv/jboss/server/${MAL}/log/" but MAL on the far end is empty. So you need 
to complete the expansion before calling ssh.

format: /srv/jboss/server/${MAL}/log/

Where MAL is assigned via the pipeline and then I try to ls -ltr the fully 
qualified path after MAL has been expanded.  However I'm not getting it to 
expand; wondering what I'm doing wrong.

node {
MALarray = params.multi.split(',')

MALarray.each { MAL ->
 
if (MAL in ['care''] )  {
servers = ['xx.xx.xx.xx','xx.xx.xx.xx']
}

def soc_remote = [:]
soc_remote.name = "${MAL} SOC"
soc_remote.allowAnyHosts = true

withCredentials([usernamePassword(credentialsId: 'Credentials', 
usernameVariable: 'USER_ID', passwordVariable: 'USER_PASSWORD')]) {
soc_remote.user = USER_ID
soc_remote.password = USER_PASSWORD
servers.each { server ->
soc_remote.host = server
stage("Run script on ${server}") {
try {
echo("MAL is ${MAL}")
sshCommand remote: soc_remote, command: "ls -ltr ${filepath}"
} catch (err) {
  echo "something failed"
  echo "${err}"
  }
}
}
}
}
} 

Console output:
*11:59:34* MAL is care 
*11:59:34* [Pipeline] sshCommand 

 
*11:59:34* Executing command on care SOC[xx.xx.xx.xx]: ls -ltr
