Hi! I am trying to use environment variables with the templating engine, so that I can modify an output xml based on an environment variable. This is working for me: in stubs.json "transformers": ["response-template"], "bodyFileName": "my.xml", "transformerParameters": { "newIp": "192.168.1.1" } and in xml file: uri="https://{{parameters.newIp}} Now, I would like to use the value of an environment variable instead of hardcoding the IP in the newIp parameter. I have tried setting the variable in docker compose, but then I get java.util.MissingResourceException error. I have been playing with several combinations of {{systemValue type='ENVIRONMENT' key='SERVER_IP' default='127.0.0.1'}} in payload or stub file, but I get the java error or no substitution is performed. In one case, I got this trace in the output payload: uri="https//[ERROR Access to SERVER_IP is denied] How could I do this? Thanks in advance for your help!

If I remember correctly, WireMock restricts the values that can be retrieved from the environment or system properties. If you haven't configured anything then by default the keys you use will have to be named to match the

wiremock.*

regex

Right! I changed the variable declaration in docker compose to: - WIREMOCK_SERVER_IP=192.168.1.1 and it works perfectly with this substitution: {{systemValue type='ENVIRONMENT' key='WIREMOCK_SERVER_IP' default='127.0.0.1' Thank you very much!!

Excellent. Glad it worked
