Create SystemD unit files for web and worker in /etc/systemd/system/

$ vim /etc/systemd/system/concourse-web.service  
[Unit] 
Description=Concourse CI web process (ATC and TSA) 
After=postgresql.service 
[Service] 
User=concourse 
Restart=on-failure 
EnvironmentFile=/etc/concourse/web_environment 
ExecStart=/usr/local/concourse/bin/concourse web 
[Install] 
WantedBy=multi-user.target 
 
Then the SystemD Unit File for the Worker Service: 
$ vim /etc/systemd/system/concourse-worker.service  
[Unit] 
Description=Concourse CI worker process 
After=concourse-web.service 
[Service] 
User=root 
Restart=on-failure 
EnvironmentFile=/etc/concourse/worker_environment 
ExecStart=/usr/local/concourse/bin/concourse worker 
[Install] 
WantedBy=multi-user.target 
 

Before running Concourse prepare iptables so that it will forward the containers traffic, otherwise the worker will not be able to pull from docker hub

sudo iptables -P FORWARD ACCEPT 
sudo systemctl start concourse.web
sudo systemctl start concourse.worker
