Firebase in a Docker container

[elamison]

I'm trying to retrieve data from a firebase database in node.js which works fine until i run it in a Docker container.

 

const ref = firebase.database().ref(`datasource/${userId}`)
    .once('value').then( (snapshot) => {
      console.log(snapshot.val());
      return callback(null, 'ok');
    }, (error) => {
      console.error(error);
    });

I think this is the problem (from the docker syslog):

dropping unexpected TCP packet sent from 172.18.0.3:33368 to 216.58.210.173:443 (valid sources = 192.168.65.2, 0.0.0.0)

I'm not sure what firebase is doing in the response but I'm able to make requests fine to google.com and twitter. Is this something I can address with firebase or a docker issue?

After digging more I think it's something with Docker's bridge but it seems that Google/Firebase (216.58.210.173:443) is rejecting the packet because the source IP is not in a valid list.
