I'm trying to put cdn domain as assetPrefix and it always resolves on build time however I want to resolve during runtime. Is there a possible way to do it? I want to do this to share same docker image across enviorments. Following is how my config file looks like - 
const cloudFrontUrl = process.env.CDN_DOMAIN

const nextConfig = {
    transpilePackages: packages,
    assetPrefix: cloudFrontUrl,
    output: 'standalone',
    webpack: (config) =>

We created the image by having .env file as
NEXT_CDN_URL=NEXT_ENV_START_NEXT_CDN_URL_NEXT_ENV_END

And when container starts we run a script to replace NEXT_ENV_START_NEXT_CDN_URL_NEXT_ENV_END with process.env.cdn_domain from k8..

Its not a proper solution but works
