Installation

Docker

1. Install necessary packages to use a repository over HTTPS :

   sudo chmod a+r /etc/apt/keyrings/docker.gpg

3. Add the repository to apt sources :

   echo \
   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
   $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
   sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4. Update system :

   sudo apt update

         container_name: portainer
         ports:
            - 9443:9443
         #networks:
         #   - nginx-proxy
         volumes:
            - ./data:/data
            # Bind the host’s Docker socket to manage the Docker installation it’s running within.
            - /var/run/docker.sock:/var/run/docker.sock
         restart: unless-stopped
         #networks:
