====== Frigate NVR Installation ======


===== Docker Installation =====

Download and save the Docker repository signing key:

  curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
  
Add the Docker repository in /etc/apt/sources.list.d/docker.list:

  deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu noble stable
  
Allow unattended updates from this repository by add to /etc/apt/apt.conf.d/50unattended-upgrades:

<code>
  Unattended-Upgrade::Allowed-Origins { 
        // Append to end of existing entries
        "Docker:${distro_codename}";
};
</code>

Update the repositories and install the package:

<code>
apt update
apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin
</code>

Check all is working with:

  docker version
  
Stop the services

<code>
systemctl stop docker.service
systemctl stop docker.socket
systemctl stop containerd.service
</code>

Move the Docker root directory: (optional)

  mv /var/lib/docker /srv/data
  
Edit the systemd service for Docker:

  systemctl edit docker.service (only if moving)
  
Add the following to the top of the override file:

  <code>
  [Service]
  ExecStart=
  ExecStart=/usr/bin/dockerd -–data-root=/srv/data/docker -H fd:// --containerd=/run/containerd/containerd.sock
  </code>
  
Restart Docker:

  systemctl daemon-reload
  systemctl start docker.service
  
Check it still works with:

  docker run hello-world
  
===== GPU Hardware Acceleration =====

Download and save the NVIDIA repository signing key:

  curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | gpg --dearmor -o /etc/apt/keyrings/nvidia-container.gpg
  
Add the Docker repository in /etc/apt/sources.list.d/nvidia-container.list:

  deb [signed-by=/etc/apt/keyrings/nvidia-container.gpg] https://nvidia.github.io/libnvidia-container/stable/ubuntu18.04/$(ARCH) /
  
Allow unattended updates from this repository by add to /etc/apt/apt.conf.d/50unattended-upgrades:

<code>
Unattended-Upgrade::Origins-Pattern {
        "site=nvidia.github.io";
};
</code>

Update the repositories and install the package:

<code>
apt update
apt install nvidia-docker2
</code>

Restart Docker:

  systemctl restart docker.service
  


===== Frigate =====

If using ZFS, create a filesystem to store the video recordings (not used currently)

  zfs create -o recordsize=1M -o compression=off -o quota=256G data/cctv
  
Create a configuration directory for Frigate:

  mkdir /etc/frigate
  
Create /etc/frigate/docker-compose.yml:

<code>
version: "3.9"
services:
  frigate:
    container_name: frigate

Start Frigate with:

  docker compose -f /etc/frigate/docker-compose.yml up -d
  
Visit the Frigate interface via:

  http://server:5000/
  
Update the Image with

  docker compose -f /etc/frigate/docker-compose.yml down
  docker compose -f /etc/frigate/docker-compose.yml pull
  docker compose -f /etc/frigate/docker-compose.yml up    (Add the -d option to start with a detach option)
  
  docker image prune
  docker container prune 
  (on an upgrade)
