Correction: the *s6_service_path* parameter in the parent init.d service, |
| 2 |
/etc/init.d/container, needs to be changed from |
| 3 |
/run/openrc/s6-scan/${INSTANCE} to /var/svc.d/${INSTANCE} |
| 4 |
|
| 5 |
|

|

*#!/sbin/openrc-rundescription="A supervised test service with a |
| 10 |
logger"supervisor=s6**s6_service_path=/var/svc.d/${INSTANCE}* |
| 11 |
|
| 12 |
*depend() {* |
| 13 |
* need s6-svscan* |
| 14 |
*}* |
| 15 |
|
| 16 |
*stop_pre() {* |
| 17 |
* docker stop ${INSTANCE}* |
| 18 |
*}* |
| 19 |
|
| 20 |
NB; In runlevels, dont need to include s6-svscan. Only need to include the |
| 21 |
service to start (s6-svscan will start as a service dependency). |
