Hello Everyone, Unable to disable gzip in WireMock Docker – container exits immediately when using

--no-gzip

Description:

I'm running WireMock via Docker and trying to disable gzip compression because my client needs uncompressed responses.

I've tried:

1.

Setting the environment variable:

docker run -d \ --name wiremock \ -p 8080:8080 \ -e WIREMOCK_NO_GZIP=true \ wiremock/wiremock:latest …but the responses still contain

Content-Encoding: gzip

. 2. Passing

--no-gzip

as a CLI flag: docker run --rm -it \ -p 8083:8080 \ wiremock/wiremock:3.9.1 \ --verbose --no-gzip …but the container immediately exits with: Exception in thread "main" java.util.MissingResourceException thrown from the UncaughtExceptionHandler in thread "main" 3. Using older versions (e.g.,

2.35.0

) with

--no-gzip

results in:

joptsimple.UnrecognizedOptionException: no-gzip is not a recognized option

W*hat I’ve confirmed:* • Docker image pulls and runs fine without

--no-gzip

. • Problem only occurs when trying to disable gzip. • Removing containers and images before retrying doesn’t fix it. Questions for the community: • What is the correct way to disable gzip in the latest WireMock Docker image? • Is

--no-gzip

supported in the official Docker images, and if so, from which version? • Could the

MissingResourceException

be a packaging issue in recent releases?
