My env variables are not working in production (even while using PAYLOAD_PUBLIC_ prefix)

admin: {

   preview: (doc) => {
      const page = doc as any as Home;
      
      let pathToUse = '';
      
      if (page.page) {
        pathToUse = page.page.slug === 'home' ? '' : page.page.slug;
      }

      return `${process.env.PAYLOAD_PUBLIC_WEB_URL}/api/preview? url=${process.env.PAYLOAD_PUBLIC_WEB_URL}/${pathToUse}`;
    },
...
}

  I'm pretty sure the

  PAYLOAD_PUBLIC_

  env variables are being replaced when you build payload (probably somewhere in your CI pipeline) Perhaps you need to define the env variables you want to use for production in there as well 🙂

  When I add

  dotenv.config()

  it appears to be working

  
  

  
  

  it just feels like this is not what the docs are trying me to tell

  check out this thread:

  Can you point me to the docs that confused you? Maybe we need to clean a section up

  Actually this reply sums it nice up:

  I guess I was looking at it the wrong way, I just looked at it as one build. But there is of course a separation in server and client build.

  It's not really clear from this imo:

  https://payloadcms.com/docs/admin/environment-vars#environment-variables-in-admin-ui
  

  had to find this thread

  
  

  
  

  If you're using Docker you will need to provide args for the build step and modify the Dockerfile

  do you have a example of integrating env vars in Dockerfile?

•

  @August sure

  
  

  ARG PAYLOAD_PUBLIC_MERLIN_URL=http://localhost:3000
  ENV PAYLOAD_PUBLIC_MERLIN_URL=$PAYLOAD_PUBLIC_MERLIN_URL

  
  

  
  

  and then supply the arg during build time
