OSX failed to access service running in container via private ip and port of this container


(Lethe3000) #1

Expected behavior

I’m running nginx using docker-compose
PORTS NAMES 80/TCP, 443/TCP nginx
and the private ip of nginx container is
root@3f094934d933:/app/src# ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1 link/sit 0.0.0.0 brd 0.0.0.0 3: ip6tnl0@NONE: <NOARP> mtu 1452 qdisc noop state DOWN group default qlen 1 link/tunnel6 :: brd :: 4: ip6gre0@NONE: <NOARP> mtu 1448 qdisc noop state DOWN group default qlen 1 link/gre6 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 brd 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 83: eth0@if84: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 02:42:ac:12:00:04 brd ff:ff:ff:ff:ff:ff inet **172.18.0.4**/16 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::42:acff:fe12:4/64 scope link valid_lft forever preferred_lft forever

I trying to access nginx by 172.18.0.4 in browser, but cannot connect 172.18.0.4
on my ubuntu machine access to private ip of container is OK, so I wonder how to access this nginx service via http://private ip:80

It seems the docker virtual machine issue since latest docker engine on mac does not use virtual box.
