systemd service file always does start and stop

772

have created a new systemd service for botpress If I do

systemctl start botpress.service

it Starts all the botpress stuff then immeaditly runs the ExecStop stuff. Systemctl starts fine if I remove ExecStop=.......

the script being called works just fine.

cat /etc/systemd/system/botpress.service 
[Unit]
Description=botpess
After=docker.service

[Service]
Type=simple

TimeoutStartSec=5s
ExecStartPre=/bin/bash -c 'echo ">>>>>>>>>>> pre-starting botpress <<<<<<<<<<<<<<<"'
ExecStart=/etc/systemd/system/botpress.initd start
ExecStartPost=/bin/bash -c 'echo ">>>>>>>>>>> post-starting botpress <<<<<<<<<<<<<<<"'


ExecStop=/etc/systemd/system/botpress.initd stop
ExecStopPost=/bin/bash -c 'echo ">>>>>>>>>>> post-stopping botpress <<<<<<<<<<<<<<<"'

[Install]
WantedBy=multi-user.target

I can put put the botpress.initd script in /etc/init.d and get systemctl to stop and start but will not restart at reboot. all I want to do is just call a simple script that can start and stop on demand and enable at reboot

cat botpress.initd 
#! /bin/bash -x

It sounds as though it may be a "one shot" command.

What that means is that you start the process with systemd then as soon as it is up and running systemd takes over responsibility for it and runs it in the background. The process ID was only needed to start it, not to keep it running.

To test, please run and show the outcome here, of : systemctl status botpress.service - amend "botpress" if that is not the actual name of the package.

To start the process as a systemd unit at boot, run sytemctl enable botpress.service at anytime before the next reboot. Now would be good.

well well I feel like the fresh college grad with no experience.

Talking with vendor all I needed was to add "restart: always" to my compose file and let docker do the rest.

    services:
      botpress:
        build:
          context: ./botpress
          dockerfile: Dockerfile
        image: botpress-serve
        restart: always
        container_name: botpress-server
        command: bash -c "export AUTO_MIGRATE=true; ./bp --auto-update"
