Docker Container kann nicht angestoßen werden

Question

Neu Docker auf Mac OSX. Ich baue ein Ubuntu-Bild aus dem Basisphlogabild, um es als Git-Server zu verwenden. Verwenden Sie die folgende Datei, um die Basis und die benötigte Software zu installieren. Das funktioniert großartig. Ich kann jedoch die Maschine nicht anpingen.

EDIT

---

Ich bin nicht in der Lage, die Maschine pingen. Ich kann das Bild ausführen und den Container im Befehl ps sehen. Ich kann mich auch darauf einlassen.

Answer 1

Wie in "Can't visit http://172.17.0.2:5000 after starting docker registry" erwähnt, können Sie die interne IP-Adresse container-to-container communication nicht verwenden.

Sie müssen die IP-Adresse verwenden, die von $(docker-machine ip <yourMachine>) zurückgegeben wird, um tatsächlich die Maschine zu pingen, die Ihren Container ausführt.

Update Februar 2017 Docker 1.13+: als commented von kboom, haben Sie jetzt Docker for Mac, die eine leichte Hypervisor verwendet (HyperKit), die localhost gebunden sein kann (aber immer noch kann man nicht interne Adressen besuchen).
