I wanted to start expermineting with Photon OS Docker /Vmware Orchestrator and so on.
But i'm struggling just at the beginning.
What I did so far:
Used ISO (photon-1.0-13c08b6.iso) and even the OVA-Template (same Version) to install an instance of Photon OS. Host is vSphere 6.0 U2 or Workstation 12 Pro.
Installation seemed to be fine. I did some local testing with nginx as described in the wiki and even there I can connect to the nginx instance.
I changed permissions to ssh to login as root --> it works.
1. I cannot ping the Photon Host
2. Cannot connect to docker from "outside" to 2375. I changed the docker.service file and localy I can connect docker using -H ...:2375
So my question is, why I'm not able to connect from the "outside"
Photon OS is using an iptables firewall, which by default block everything except the SSH.
You can allow ping on iptables by running these commands:
# iptables -A OUTPUT -p icmp -j ACCEPT
# iptables -A INPUT -p icmp -j ACCEPT
