Sometimes vplc start before local codemter service

[Leeable]

sometimes vplc started before codemeter service leads to no license condition. maybe should add extra command in template.service?

[Unit]
Description=VPLCNEXTCONTROL CONTAINER
After=network.target

ConditionPathExists=/usr/lib/systemd/system/codemeter.service


[Service]
Type=simple

# fix when vplc service start before host codemeter
ExecCondition=/bin/bash -c "if [ -f /usr/lib/systemd/system/codemeter.service ]; then while ! systemctl is-active --quiet codemeter.service; do sleep 1; done; fi"

Hello @Leeable ,
thanks for the info I haven´t run into those issues yet on my hardware.
You are right in some circumstances you might want to add CodeMeter as a condition.
Did you also test just using the default SystemD solution for service dependencies?
e.g.:

[Unit]
Requires=codemeter.service
After=codemeter.service

This is however dependent on having CodeMeter running on the same installation at all.
That is not always the case, sometimes an external CodeMeter instance is used instead.

Maybe we can achieve a general solution instead or I will add another service template file to choose from during installation. (or maybe detect during installation if CodeMeter is installed on the host and decide depending on that)

# If CodeMeter exists, wait for it to become active.
ExecCondition=/bin/bash -c '
  if systemctl list-unit-files | grep -q codemeter.service; then
    echo " CodeMeter service exists, waiting for it to be active..."
    while ! systemctl is-active --quiet codemeter.service; do sleep 1; done
  else
    echo "CodeMeter service does not exist, continuing without waiting."
  fi

@OWarneke Hi, yes, I have encountered this situation, it happens about 3 times out of 20 or so. When this situation occurs, there is no license being used on codeMeter, I need to restart the container or use systemctl restart pclnext again.

Did you also test just using the default SystemD solution for service dependencies?
e.g.:
[Unit]
Requires=codemeter.service
After=codemeter.service

Nope, I decided not to use this method because it is not widely used. If I do not have CodeMeter installed on the host machine.
