Hi all, i am building pipeline on my project that uses 5 DB servers.

So based on build variable i want to set node name. Like this..

env.NODE = 'blabla'


node('${NODE}') {
  //some code
}

but each time i get error - There are no nodes with the label ‘${NODE}’

Thanks for help in advance...

Use double quotes if you want expressions resolved.

Why don't you just do:
def nodeLabel = 'blabla'
node(nodeLabel) {
...
}

?

Here you seem to want to define an environment variable. Not a pipeline (groovy) variable. Is this intended?

It looks like the word 'ENVIRONMENT' is misspelled in the stacktrace - not sure if this is the problem. The stacktrace indicates the error occurs on line 56 of your script, so it would help to know what is on that line.
