Installing Docker

  1. Log into the Linux based device
  2. Run the following commands in the terminal
    # install prerequisites
    sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg-agent -y
    # add docker gpg key
    curl -fsSL https://download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release)/gpg | sudo apt-key add -
    # add docker software repository
    sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release) $(lsb_release -cs) stable"
    # install docker
    sudo apt install docker-ce docker-compose containerd.io -y
    # enable and start docker service
    sudo systemctl enable docker && sudo systemctl start docker
    # add the current user to the docker group
    sudo usermod -aG docker $USER
    # reauthenticate for the new group membership to take effect
    su - $USER

Running the Pi.Alert Container

  1. Now that Docker is installed, run the following commands to setup the Pi.Alert Docker container and run it
    # create working directory
    mkdir ~/docker/pialert -p
    # set ownership on the working directories
    sudo chown "$USER":"$USER" ~/docker -R
    # run temp pialert container
    docker run -d --name=pialert --net=host -e TZ=America/New_York jokobsk/pi.alert
    # copy default config files to host
    docker cp pialert:/home/pi/pialert/config ~/docker/pialert/
    # copy db to host
    docker cp pialert:/home/pi/pialert/db ~/docker/pialert/
    # remove the temp container
    docker rm pialert --force
    # run the pialert container
    docker run -d --name=pialert --net=host -e TZ=America/New_York -v ~/docker/pialert/db:/home/pi/pialert/db -v ~/docker/pialert/config/:/home/pi/pialert/config/ --restart=unless-stopped jokobsk/pi.alert
