How to start Sametime automatically when the OS starts

Source: HCL KB

In the HCL Knowledge Base, there is an article on how to configure Sametime 12 to start automatically after the operating system starts.
And what is the procedure?

• Create a file similar to the one mentioned below under “/etc/systemd/system”
  docker-compose-app.service
• Edit this file and add the below entries to that.
  [Unit]
  Description=Docker Compose Application Service
  Requires=docker.service
  After=docker.service
  
  [Service]
  Type=oneshot
  RemainAfterExit=yes
  WorkingDirectory=/opt/sametime/
  ExecStart=/usr/bin/docker-compose up -d
  TimeoutStartSec=0
  
  [Install]
  WantedBy=multi-user.target
  
  
• Save the file.
  
  Note : Change the “WorkingDirectory” & “ExecStart” path according to your environment.
  
• Run the below command to enable the service to start automatically.
  systemctl enable docker-compose-app.service
  
• Run the below command to start the service
  systemctl start docker-compose-app.service
  
• Run the below command and check if the docker-compose is started properly
  systemctl status docker-compose-app.service
  
  Note: It may take some time to start all the containers.
  
• Check if the Sametime is working properly from the embedded client \ Proxy or meetings.
• If everything is working, do a docker-compose down and restart the OS. Wait for the OS to reboot completely and you can run the command mentioned in step#6 to check if the Sametime server is started.
  
  Troubleshooting
• In case any change is done in the “docker-compose-app.service” file, do a “systemctl daemon-reload” to reload the unit.
• In case the service is not loading, run the command “journalctl -xe” \ or systemctl status docker-compose-app.service and check the error associated.
