How to restore from a fatal

The objective is to describe the steps to restore everything from a fatal (disk failure/hardware failure)

Install clean distro

• Install Ubuntu LTS (in my case 20.04)
• Add my user/password and make sure there is ssh without a password
• Change to static ip outside of dhcp range

configure vi /etc/netplan/01-network-manager-all.yaml 
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: networkd
  ethernets:
     enp1s0:
       dhcp4: no
       dhcp6: no
       addresses: [10.0.0.xxx/24]
       gateway4: 10.0.0.xxx
       nameservers:
         addresses: [8.8.8.8,8.8.4.4]

• Install nfs-common sudo apt install nfs-common

• Install docker and docker-compose

Network docker-compose

• Sync netdc folder
• Open wiregaurd secret folder to remote cfg/wireguard
• Copy systemd service and restart
• Check docker-compose up -d and logs

copy dnet.service to  /etc/systemd/system/
sudo systemctl enable dnet.service 
sudo systemctl start dnet.service 

Hass docker-compose

Unfortunately, there are a few steps here as Hass didn't make it simple to reconstruct everything

• Sync main folder to remote
• From hass create a user/pass and long live token and update the secret API for appd to work
• Load Solaredge and xiaomi sensors manually (in the past it was automatic, new version are going backward ..)
• Restore the influxdb db with the commands
• Copy dhass.service and restart the service

hopefully that it! (docker made it much simpler to restore it)
