How to install Portainer on a Synology NAS using Container Manager / Docker Compose

Watch a guy with a cold clear his throat a lot while installing Portainer using just the built in Synology application Container Manager. A little help from Text Edit too. Credit to the composerize website for providing the much helpful docker-run to docker-compose translation service. While Portainer and Container Manager are similar, there might be a few uses for Portainer. You can access what are known as "docker volumes" in Portainer without needing to SSH into your NAS. I don&believe Container Manager has that ability. You can also follow a lot of portainer tutorials out there. If you&just getting started in this container world, it might be easier to follow those than to try to figure out how a portainer tutorial could work in Container Manager.
