The Docker host has IP v6 disabled, but the container V 2.5.0 has enabled IP v6

noschvie@tvmtdevroundup:~/Roundup$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1 

noschvie@tvmtdevroundup:~/Roundup$ docker exec -it roundup /bin/sh
~ $ ping localhost
PING localhost (::1): 56 data bytes
64 bytes from ::1: seq=0 ttl=64 time=0.166 ms
64 bytes from ::1: seq=1 ttl=64 time=0.060 ms
^C
--- localhost ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.060/0.113/0.166 ms

~ $ sysctl net.ipv6.conf.all.disable_ipv6
net.ipv6.conf.all.disable_ipv6 = 0


But the container image 2.3.0 has IP v6 disabled

noschvie@tvmtmcsdebian12dev:~$ docker exec -it roundup /bin/sh
~ $ ping localhost
PING localhost (127.0.0.1): 56 data bytes
