I'm trying to run a rails server using the below systemd script:

This is the output I get from journalctl -xe

I can run the command /bin/bash -lc 'bundle exec rails s -e production -b 0.0.0.0 -p 3010' just fine in my terminal, as the user ubuntu, but for some reason it isn't running as a systemd script.

I'm trying to install docker on my virtual machine:
Update the apt package index and install Docker
$sudo apt update
$sudo apt install docker.io -y
Add current user to the docker group:
$sudo usermod -aG docker ${USER}
$su - ${USER}
Check whether you can access and download images from Docker Hub
$docker run hello-world
When I start docker, I get this error
liaomei#liaomei-virtualbox:~$ systemctl start docker
Job for docker.service failed because the control process exited with error code.

I can't find the actual error in these output. Could you tell me where the problem is and how to fix it.
I'm following the Certified Kubernetes Application Developer (CKAD) Certification, and in their manual they are providing a bash file to deploy a master node using Kubeadm, and this is it's content :
https://gofile.io/d/d2l1UJ
But when I run this bash file using: sudo bash deploy.sh I get an error message as shown in this screenshot:
I tried to start docker using: sudo systemctl start docker but I get this error:
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.
So then I run systemctl status docker.service and I get this:

I installed Kubuntu 18 about 3 weeks ago on partition in 28G(sdb5), but after installing of docker seems this space is not enough for my root partition
I found that /var/lib/docker/ takes 11.1 GiB.
I found a decision of using sdb7 partition for docker which is not used now.
So after I formatted /sdb7 into ext4 and used /sdb7 in /etc/fstab and restarted OS I run:
cd /var/lib
sudo rsync -av docker /mnt/_work_sdb7
sudo mv docker docker.old
sudo ln -s /mnt/_work_sdb7/docker
and next :
$ docker-compose up -d --build
ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
I found a way of fixing such error:
sudo usermod -aG docker $USER
sudo newgrp - docker
But it did not help. Next :
Some configation/permittions missing?
# docker-compose --version
docker-compose version 1.17.1, build unknown
# docker --version
Docker version 19.03.2, build 6a30dfc

?
MODIFIED 3 :
I found /etc/systemd/system.conf in which all parameters were commented
I uncommented or added parameters with some values, incrementing them and restarting OS. I made so several times and at least I have :
DefaultStartLimitIntervalSec=350s
DefaultStartLimitBurst=260
StartLimitInterval=350s
StartLimitBurst=260
StartLimitIntervalSec=260
while all the rest parameters commented, But any way I see errors :

вер 14 18:05:44 serge-at-hoe systemd[1]: Failed to start Docker Application Container Engine.
Which values must have these(or some others) values ?
MODIFIED # 4 :
I tried in /etc/systemd/system.conf to change some values to zero, as I googled such possible decision:
DefaultStartLimitIntervalSec=0
DefaultStartLimitBurst=260
StartLimitInterval=350
StartLimitBurst=260
StartLimitIntervalSec=0
But restarting OS I failed to login into the system and has a lot of flash messages on the screen.
I modified the file with all 0 :
DefaultStartLimitIntervalSec=0
DefaultStartLimitBurst=0
StartLimitInterval=0
StartLimitBurst=0
StartLimitIntervalSec=0
I reloaded ok but running docker I still have "Start request repeated too quickly" errors:

I am not sure if that valid options in /etc/systemd/system.conf or some other issue?
Did you typed:
sudo systemctl start docker
sudo systemctl enable docker
?
The way you are trying to install docker on another partition is not correct.
You need a partition (sdb7 in your case). Suppose its mounted at /mnt/sdb7
Docker by default store all its data (containers, images and so on) in /var/lib/docker you need to change this in your case to something like /mnt/sdb7/docker using data-root option of docker.
While starting docker deamon use --data-root option.
dockerd --data-root=/mnt/sdb7/docker
Hope this helps.
Update:
The dockerd command will run in foreground.
You need to set --data-root option permanently for docker.service that you start/stop using systemctl.
To set that option permanently refer this.
You need to add this line "data-root": "/mnt/docker-data" in /etc/docker/daemon.json file.
Update-2:
docker.socket: Failed with result 'service-start-limit-hit' means docker.service seems to fail and restart to fast. The is explained here.
You need to edit systemd file for docker using systemctl edit docker.service as mentioned here and tweak the values of StartLimitIntervalSec= and StartLimitBurst= as mentioned here so that the docker.service will not fail to quickly.
Update-3:
Editing /etc/systemd/system.conf file is dangerous it might cause serious problem with your VM. What I suggested was to change make change using systemctl edit docker.service.
The docker.service systemd file contents should be similar to this.
Also refer this.

my daemon.json(/etc/docker/daemon.json)is not exist, when i create a daemon.json with its content '{}'，also error
I have tried some ways:
clear /var/lib/docker
reinstall docker-ce
docker's old version docker and docker-io is normal,but it no ip and port mapping， so i use docker-ce now.
how to fix this question?
Docker can be started with two different methods :
Via systemctl, which is the recommanded way
Directly via the docker daemon bin : dockerd which is not the recommanded way
However, when you start the docker daemon directly (ie not with systemctl), systemctl has no way to know the current status of the daemon.
So my guess is that, after the install, the docker daemon was somehow partially started and failed.
To check if that's the case, just run :
sudo ps -aux | grep dockerd
Then kill all the process attached to the docker daemon.
When it is done, you should be able to start docker directly via systemctl.
So I installed docker engine on RHEL 7
Now when I do a
service docker start
I get the following error:
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
and when I go to "systemctl status docker.service" and "journalctl -xe"
I get:

I tried to search solution for this
but could not find any.
Just Remove Docker Lib and restart it again with:
sudo rm -rf /var/lib/docker
then
sudo systemctl enable docker
sudo systemctl start docker
Check your OS logs files for warning or error messages.
Probably you have made a mistake in the config files of docker and when the service starts it gets an error.
The log's location depends on your OS.
On Linux system logs are often in:
/var/log/daemon.log
/var/log/docker
/var/log/messages
/var/log/syslog
/var/log/upstart/docker.log
Some useful linux console commands to inspect docker logs:
sudo systemctl status docker.service
sudo journalctl -fu docker.service
cat /var/log/daemon.log | grep docker
cat /var/log/messages | grep docker

What version of Docker do you use? If you are not locked to the elder one, consider use of the most recent version (currently it's 1.12). Here's my startup options (Debian 8, /etc/systemd/system/docker.service):
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network.target docker.socket
Requires=docker.socket
[Service]
Type=notify
ExecStart=/usr/bin/docker daemon -H fd:// --dns=10.240.116.7 --dns 8.8.8.8 --bip=172.17.42.1/24
MountFlags=slave
LimitNOFILE=1048576
LimitNPROC=1048576
LimitCORE=infinity
TimeoutStartSec=0
[Install]
WantedBy=multi-user.target
Also try to start Docker in debug mode (-D) without systemd, just like if it was a common program. This will help to find out why daemon doesn't start.
Fixing the Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. problem, for me this worked:
create daemon.json in /etc/docker/
put this in it:
{
"exec-root": "/path/to/docker/run",
"storage-driver": "overlay",
"graph": "/path/to/docker/lib"
}
then try: docker daemon
reboot
docker run hello-world should succeed now
There are many reasons for docker service failing to run. One of them that I encountered is using single quotes instead of double quotes for the key value pairs in the json file.
It fails
sudo cat > /etc/docker/daemon.json << '_EOF'
{
'registry-mirrors': ['https://docker.io']
}
_EOF
It works!
sudo cat > /etc/docker/daemon.json << '_EOF'
{
"registry-mirrors": ["https://docker.io"]
}
_EOF

I came across same issue in my Linux VM(virtual machine).
System details : ubuntu 18.04
I had to just delete my daemon.json and then do a service docker start this worked for me.
Note: I had put insecure registry in my daemon.json file and i didn't want that as well hence i deleted it. I don't know it's usage though.
