Project Photon OS is an open source, minimal Linux container host that is optimized for cloud-native applications, cloud platforms, and VMware infrastructure.

Star in Vagrant

nano Vagrantfile
Vagrant.configure("2") do |config|
  config.vm.box = "devopstales/photon3"
  config.vm.synced_folder ".", "/vagrant", type: "virtualbox"

  config.timezone.value = :host
  config.vm.provider "virtualbox" do |vb|
    vb.name = "photon01"
      vb.memory = 4096

      vb.cpus = 2
      vb.linked_clone = true
      vb.customize ["modifyvm", :id, "--vram", "8"]
  end

  config.vm.define "pothon01" do |vbox|
    vbox.vm.network :public_network, ip: "192.168.0.112" , bridge: "wlan0" #, adapter: "1"
    vbox.vm.hostname = "pothon01.mydomain.intra"
    vbox.hostsupdater.remove_on_suspend = false
    vbox.vbguest.auto_update = false
  end
end

vagrant up
vagrant ssh

When you try to login the server wants you to change the passowrd of the vagrant user. The base password is vagrant as usual.

vagrant ssh
You are required to change your password immediately (password expired)
Last login: Sun Apr 14 20:30:22 2019 from 10.0.2.2
WARNING: Your password has expired.
You must change your password now and login again!
Changing password for vagrant.

Retype new password:
passwd: password updated successfully
Connection to 127.0.0.1 closed.

Vagrant can’t configure the ip, hostname and mount the /vagrant fonder.

Package management

On Photon OS, tdnf is the default package manager for installing new packages. It is a C implementation of the DNF package manager without Python dependencies. DNF is the next upcoming major version of yum.

Let’s install packages for the next steps.

tdnf install nano awk tar build-essential linux-devel less -y

Install virtualbox guest additions

Example image

mount /dev/cdrom /mnt/cdrom
cd /mnt/cdrom
./VBoxLinuxAdditions.run

Configure static ip

PhotonOS use systemd-networkd to manage network configurations. systemd-networkd configorations is located under /etc/systemd/network/.

cat /etc/systemd/network/99-dhcp-en.network
[Match]
Name=e*

[Network]
DHCP=yes
IPv6AcceptRA=no

cat > /etc/systemd/network/20-static-eth1.network << "EOF"
[Match]
Name=eth1

[Network]
DHCP=no
Address=192.168.0.112/24
Gateway=192.168.0.1
DNS=8.8.8.8
Domains=mydomain.intra
NTP=0.pool.ntp.org
EOF

chmod 644 /etc/systemd/network/20-static-eth1.network
systemctl restart systemd-networkd
systemctl status systemd-networkd -l

Configure hostname

hostnamectl set-hostname "pothon01.mydomain.intra"

hostnamectl status
   Static hostname: pothon01.mydomain.intra
         Icon name: computer-vm
           Chassis: vm

    Virtualization: oracle
  Operating System: VMware Photon OS/Linux
