dris (docker-run-in-systemd) is a tool that (tries to) simplify the management of systemd services for apps that run in docker containers.
If you know how to run a container, you can use dris run instead of docker run and expect the container to run as a systemd service, which would automatically restart on-failure, and at boot time.
Disclaimer: Although I'm using this to run some pet projects, this HAS NOT been thoroughly tested.
curl -sSL https://raw.githubusercontent.com/stang/docker-run-in-systemd/main/get-dris.sh | sudo sh
# list all DRIS services
dris ps
# docker run 'nginx' thru systemd (with autoboot)
dris run --net host -v /data/www:/usr/share/nginx/html:ro nginx:1.18
# deploy newer version of nginx
dris run --net host -v /data/www:/usr/share/nginx/html:ro nginx:latest
# stop the service (and disable autoboot)
dris stop nginx
# uninstall the service
yes | dris rm nginx
Because we aimed for simplicity, the service name is infered from the DOCKER_IMAGE.
Therefore, calling dris run with the same image would override the existing config.
At the moment, you can't dris run the same DOCKER_IMAGE more than once on a given host.
