Container services over IPv4 IPv6

[mateodurante]

Steps to Reproduce

1. Create a container using Docker or Docker Compose that utilizes IPv6 (I used Kubernetes).
2. Attempt to access:
   

Expected Behavior

All internal services should be accessible over both IPv4 and IPv6 (*:port).

Observed Behavior

The ShareLaTeX container ports are only listening over IPv6 ([::]:port).

Context

I recently created a new environment using Kubernetes, and it doesn't seem to connect. When I recreated the same environment using Docker with IPv4, it functioned correctly:

Technical Info

• URL: NA
• Browser Name and Version: NA
• Operating System and Version (Desktop or Mobile): Kubernetes cluster K3S
• Signed in as: NA
• Project and/or File: https://github.com/mateodurante/overleaf-docker

Analysis

• Disabling IPv6 for the container/cluster is not an option in my infrastructure (like other comment issues suggest).
• I resolved the issue by configuring Nginx to listen on all ports for both IPv4 and IPv6 and proxying between them. See the configuration file: https://github.com/mateodurante/overleaf-docker/blob/main/sharelatex-nginx/sharelatex.conf

This should be fixed in the latest release, 5.0.3, would you mind giving it a try?
