📃Manual Steps

Manual steps to prepare Pi

*Below documentation referred user as veerendra, hostname as atom and IP as 192.168.0.120. Please change these values according your requirement

Write OS Image on SD card

• Download RaspberryPI OS Imager

Configure hostname, user, wlan and locale like below by clicking ⚙️ and click WRITE

Configure your machine

Below command should run on your machine(that you connect Pi)

• Copy ssh keys to Pi for password less authentication

  $ PIUSER="veerendra"
  $ PIIP="192.168.0.120"
  
  $ ssh-copy-id $PIUSER@$PIIP
  veerendra@192.168.0.120's password:
  
  Number of key(s) added: 1
  
  Now try logging into the machine, with:   "ssh 'veerendra@192.168.0.120'"
  and check to make sure that only the key(s) you wanted were added.

• Add ssh config

  cat >> ~/.ssh/config <<EOF
  Host atom
    HostName 192.168.0.120
    user veerendra
  EOF

Configure your Pi

Below command should on Pi

1. Login into Pi and Set root user password

   veerendra@atom:~$ sudo passwd
   New password:
   Retype new password:
   passwd: password updated successfully

2. Make the user sudoer

   • Login into pi and run below commands

   veerendra@atom:~$ PIUSER="veerendra"
   
   veerendra@atom:~$ echo "$PIUSER ALL=(ALL:ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/$PIUSER
   [sudo] password for veerendra:
   veerendra ALL=(ALL:ALL) NOPASSWD: ALL

   • Make sure you specify same user and IP in inventory.yml#L5-L6

3. (Optional)Set static IPs to interfaces

   • This will also bring up the eth0 internface which some won't come up by default

   # Set static IP for eht0
   $ {
      sudo netplan set ethernets.eth0.dhcp4=false
      sudo netplan set ethernets.eth0.addresses=[192.168.0.120/24]
      sudo netplan set ethernets.eth0.gateway4=192.168.0.1
      sudo netplan set ethernets.eth0.nameservers.addresses=[1.1.1.1]
      sudo netplan try
   }
   $ sudo netplan apply
   
   # Set static IP of wlan0
   $ {
      sudo netplan set wifis.wlan0.dhcp4=false
      sudo netplan set wifis.wlan0.addresses=[192.168.0.130/24]
      sudo netplan set wifis.wlan0.gateway4=192.168.0.1
      sudo netplan set wifis.wlan0.nameservers.addresses=[1.1.1.1]
      sudo netplan try
   }
   $ sudo netplan apply
