​
Load a static execution config from file

Instead of letting the router fetch the config from the platform, you can also point to a local file. This is handy for local development. Your production config can be fetched by running wgc router fetch or wgc router compose to generate a execution config without the need to interact with the controlplane. 
docker run \
    -e EXECUTION_CONFIG_FILE_PATH=/app/router.json \
    -v ./router.json:/app/router.json \
    --env-file ./.env router
The command above will mount your local file config.json into the router’s working directory. Docker --env-file allows you to specify all environment variables in your .env file instead of passing all of them through -e flags.

​
Watch for config changes

You can enable the watch mode to perform a hot-reload of the router whenever you make changes to the configuration. 
version: "1"

execution_config:
  file:
    path: "router.json"
    watch: true

​
Debug log level

Enable debug mode by setting the environment variable LOG_LEVEL=debug or via configuration file.
config.yaml
version: "1"

dev_mode: true
