  This statement...

  • However, if at Node level (http/s:///computer//configure), under Node Properties, you add Environment variables, those will be added to the container.

  seems to be incorrect.

  The link points to a line of code that calls

  EnvVars envHost = computer.getEnvironment();

  However, computer.getEnvironment() does not include the environment variables added via Node Properties.

  This can be confirmed by creating a node named 'node-with-properties', and adding some environment variables via Node Properties, and running the following Jenkinsfile

  node('node-with-properties') {
      docker.image('alpine').inside() {
          sh 'env'
      }
  }

  You can then inspect the output of the env command, and notice that the environment variables from Node Properties are not available inside the docker container.
