docker on windows 10: container has no ip address - docker

Question

First step: I loaded the Images from a local drive:
docker load -i postgres10.tar
docker load -i drupaldrush1.tar
Second step: I started the containers:
docker run -p5432:5432 postgres:10
docker run -p8081:8081 drupaldrush:1
Third step: displaying containers:
docker ps
results in:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b77bcc79d599 drupaldrush:1 "docker-php-entrypoi…" 33 seconds ago Up 32 seconds 80/tcp, 0.0.0.0:8081->8081/tcp flamboyant_easley
97b9ba5f2779 postgres:10 "docker-entrypoint.s…" About a minute ago Up About a minute 0.0.0.0:5432->5432/tcp competent_fermat
BUT container is not available under: localhost:8081
Fourth step: inspecting container:
docker inspect flamboyant_easley
resulting in (among other Information):
"HostConfig": {
"Binds": null,
"ContainerIDFile": "",
"LogConfig": {
"Type": "json-file",
"Config": {}
},
"NetworkMode": "default",
"PortBindings": {
"8081/tcp": [
{
"HostIp": "",
"HostPort": "8081"
}
]
},
and
"IPAddress": "172.17.0.3",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"Networks": {
"bridge": {
"IPAMConfig": null,
"Links": null,
"Aliases": null,
"NetworkID": "d5e552bf9c57050fe2debfc7d38a784580309fa0b72c4854a563e78295128912",
"EndpointID": "f61b02c5997b2e391add348686f658b4c596dd60495365cee0fee539743d4792",
"Gateway": "172.17.0.1",
"IPAddress": "172.17.0.3",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
Problem: The container is not available under localhost:8081 and not under 172.17.0.3: 8081 or 172.17.0.1:8081
Question: What do I have to do to make it run under localhost:8081?

Answer 1

The problems came from Docker for Windows. Now I got a Linux Laptop and everything works just fine.
