Hi, Hoping this is the right place to ask for some help as I am very new to s6 and not well versed on any init system.
I’m attempting to use what I understand to be the “new” s6-rc way to start some processes in a docker container. Just for testing out what I want to do, I have a oneshot who’s job is just to sleep, and a longrun that depends on the oneshot. I have created the following files [Aug 19 18:42:24 root@s6 ~]# ll /etc/s6-overlay/s6-rc.d/longrun_test/ total 12 -rw-rw-r-- 1 root root 13 Aug 17 23:19 dependencies -rw-rw-r-- 1 root root 53 Aug 19 18:29 run -rw-rw-r-- 1 root root 8 Aug 17 23:19 type [Aug 19 18:42:24 root@s6 ~]# cat /etc/s6-overlay/s6-rc.d/longrun_test/type longrun [Aug 19 18:42:24 root@s6 ~]# cat /etc/s6-overlay/s6-rc.d/longrun_test/run #!/command/execlineb -P /usr/local/bin/longrun_start [Aug 19 18:42:24 root@s6 ~]# cat /etc/s6-overlay/s6-rc.d/longrun_test/dependencies sleeponstart [Aug 19 18:42:24 root@s6 ~]# ll /etc/s6-overlay/s6-rc.d/sleeponstart/ total 8 -rw-rw-r-- 1 root root 8 Aug 15 21:53 type -rw-rw-r-- 1 root root 52 Aug 16 20:25 up [Aug 19 18:42:24 root@s6 ~]# cat /etc/s6-overlay/s6-rc.d/sleeponstart/type oneshot [Aug 19 18:42:24 root@s6 ~]# cat /etc/s6-overlay/s6-rc.d/sleeponstart/up #!/command/execlineb -P /usr/local/bin/sleeponstart I can see that my services are registered with s6-rc [Aug 19 18:43:04 root@s6 ~]# s6-rc-db list all | grep -e longrun_test -e sleeponstart sleeponstart longrun_test The test services are very simple scripts just to prove they ran [Aug 19 18:44:23 root@s6 ~]# cat /usr/local/bin/sleeponstart #!/bin/bash sleep_time=30 sleep ${sleep_time} echo "I slept for ${sleep_time}." > /tmp/i_slept [Aug 19 18:44:23 root@s6 ~]# cat /usr/local/bin/longrun_start #!/bin/bash echo "I started the longrun" > /tmp/longrun_started But when I look in tmp I never see the files created. [Aug 19 18:44:23 root@s6 ~]# ll /tmp/ total 652 -rw------- 1 root root 5516 Mar 7 20:55 s6-overlay-noarch.tar.xz -rw------- 1 root root 656864 Mar 7 20:55 s6-overlay-x86_64.tar.xz If I start the longrun manually it and its dependency do run. [Aug 19 18:50:00 root@s6 ~]# s6-rc -a change longrun_test [Aug 19 18:52:08 root@s6 ~]# ll /tmp/ total 660 -rw-r--r-- 1 root root 16 Aug 19 18:50 i_slept -rw-r--r-- 1 root root 22 Aug 19 18:52 longrun_started -rw------- 1 root root 5516 Mar 7 20:55 s6-overlay-noarch.tar.xz -rw------- 1 root root 656864 Mar 7 20:55 s6-overlay-x86_64.tar.xz So I would normally just think I am missing something to make them start on boot BUT, soon after boot I do see my oneshot running.
