Engine configuration

Imposter supports different mock engine types: Docker (default) and JVM. For more information about configuring the engine type see:

User defaults

Default mock engine configuration can be set in your home directory, under the following path:

$HOME/.imposter/config.yaml

You can add a file named imposter.config.json to the root of your project, to configure the mock engine.

This will cause any user defaults to be ignored and the project configuration will be used instead.

Example 1:

{
  "engine": "docker",
  "version": "3.33.4"
}

In this example, we use the Docker engine (the default) and version 1.23.0 of Imposter.

Example 2:

{
  "engine": "jvm",
  "version": "3.33.4"
}

In this example, we use the JVM engine and version 1.22.0 of Imposter.

By default, the Imposter container runs with a lower permissioned user, with uid/gid of 2048.

If SELinux is enabled, this user may not be able to read configuration written by this library.

To fix this, you can change the container user, using:

export IMPOSTER_DOCKER_CONTAINERUSER="$(id -u)"

This aligns the container user uid to that of your local environment.
