Describe the bug

Because Nuxt only respects system environments during build, when used (eg with Docker) there is no way to set dynamic variables in the application via environments. For this purpose I have to use an ugly workaround in the form of a shell script in the entrypoint with a docker, see:

docker-entrypoint.sh:

#!/bin/sh
set -e

# @see https://vitejs.dev/guide/env-and-mode.html#production-replacement
if [ "$NODE_ENV" = "production" ]; then
    TARGET_FILE_PATH="/app/.output/server/chunks/nitro/server.mjs"

    env | while IFS= read -r line; do
        ENV_NAME=${line%%=*}
        ENV_VALUE=${line#*=}

        FIND_STRING="REPLACE_${ENV_NAME}"

        if grep -q "$FIND_STRING" "$TARGET_FILE_PATH"; then
            sed -i "s|${FIND_STRING}|${ENV_VALUE}|g" "$TARGET_FILE_PATH"
        fi
    done

    yarn run start
fi

My Nuxt module defaults:

defaults: {
  channels: ['CZ_WEB_STORE'],
  objectStorage: {
    url: process.env.OBJECT_STORAGE_URL || 'REPLACE_OBJECT_STORAGE_URL',
  },
  imgproxy: {
    key: process.env.IMGPROXY_KEY || 'REPLACE_IMGPROXY_KEY',
    salt: process.env.IMGPROXY_SALT || 'REPLACE_IMGPROXY_SALT',
  },
  project: {
    name: 'Nextgen GO',
    description: 'This is demo project of OxyShop feature!',
    primaryColor: '#ea5b0c',
  },
  imageSizes: {
    sm: '100x100',
    md: '300x300',
    lg: '600x600',
  },
}

This solution is very bad, non-standard and unstable. Is there another solution on the Nuxt side? Or does Nuxt plan to create a similar implementation in the future? Maybe some nuxi useful command?

Additional context

docker-compose.yml:

client:
   # ...
    environment:
        NODE_ENV: production
        #
        IMGPROXY_KEY: ${IMGPROXY_KEY}
        IMGPROXY_SALT: ${IMGPROXY_SALT}

Awesome, we can close?

See https://github.com/nuxt/framework/pull/3007. This is implemented in nitropack and you will be able to override nested runtimeConfig when https://github.com/nuxt/framework/pull/3956 is merged.
