I have faced with the issue that when I create the following service:

Description=Start Service Code
After=snap.docker.dockerd.service
Wants=network-online.target
Requires=snap.docker.dockerd.service

[Service]
Restart=always
ExecStart=/snap/bin/docker run -dt --rm --privileged --shm-size=0 --group-add root -p 8080:8080/tcp -p 8081:8081/tcp -v /dev:/dev service/tag
ExecStop=/snap/bin/docker stop $(/snap/bin/docker ps | grep "service/tag" | cut -d " " -f 1)

[Install]
WantedBy=default.target

Service is not started and during start it produce few issues:

systemd[1]: myservice.service: Converting job myservice.service/restart -> myservice.
systemd[1]: myservice.service: Failed to set 'blkio.weight' attribute on '/system.slice/myservice.service' to '500': No such file 
systemd[1]: myservice.service: Passing 0 fds 
systemd[1]: myservice.service: About to execute: /snap/bin/docker run -dt --rm --privileged --shm-size=0 --group-add root -p 8080:8080/tcp -
systemd[1]: myservice.service: Forked /snap/bin/docker 
systemd[1]: myservice.service: Changed dead 
systemd[1]: myservice.service: Job 14944 myservice.service/start finished, 
systemd[1]: Started Start

Why do you need to run a container as a service?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
