Configure Static IP on PhotonOS

To obtain the name of your Ethernet link run the following command:  networkctl

If this is the first time you are using Photon OS, you will only see the first 2 links. The others got created because I ran some docker swarms and created customer network bridges.

The network configuration file is located at -

                   /etc/systemd/network/

You might see the file 10-dhcp-eth0.network. I renamed this file to static.

You can do this by running the following command -

root@photon [ ~ ]# mv /etc/systemd/network/10-dhcp-eth0.network  /etc/systemd/network/10-static-eth0.network

Use vi editor to edit the file and add your static IP, Gateway, DNS, Domain and NTP.

This is how the file would look like. 

root@photon [ ~ ]# cat /etc/systemd/network/10-static-eth0.network

[Match]

Name=eth0  <<<<<<< “Make sure to change this to your adapter. ipconfig to check adapter name”

[Network]

Address=10.xx.xx.xx/24

Gateway=10.xx.xx.1

DNS=10.xx.xx.xx 10.xx.xx.xx

Domains=na.xx.com

NTP=time.nist.gov

Apply the changes by running -

systemctl restart systemd-networkd

Try to ping out form the OS. 

Note: You will not able able to ping this VM as by default the iptables firewall blocks everything except SSH. In my next blog I will explain how to allow ping on iptables.
