NAT is disabled error when setting IPV6 loopback address in port mapping #48067
Description
Description
Previously these settings worked in my docker compose file:
my-service:
ports:
- "127.0.0.1:3000:3000"
- "[::1]:3000:3000"Now after updating docker, I get and error:
Error response from daemon: driver failed programming external connectivity on endpoint my-service (...): NAT is disabled, omit host address in port mapping [::1]:3000:3000/tcp, or use [::]::3000 to open port 3000 for IPv6-only
host port must not be specified in mapping [::1]:3000:3000/tcp because NAT is disabled
Reproduce
Not sure exactly what are the conditions but using IPV6 loopback address in port mapping causes this for me.
Expected behavior
I would expect the configuration to still work or there should be clearer instructions how to make IPV6 loopback address in port mapping work again if the configuration is invalid.
