Trivial Mikrotik in version 7 supports Docker. It would be great to run a zabbix proxy on a $79 router.
I tried running "zabbix/zabbix-proxy-sqlite3:alpine-6.0-latest" docker image on router MikroTik hAP ac².
The container starts without any problem but finally crashes with this error:
"zabbix_proxy [2]: cannot create locks: cannot allocate shared memory for locks"
I looked it up, and it's a MikroTik "bug/missing feature": https://forum.mikrotik.com/viewtopic.php?t=178342#p886791
Shared Memory (SHM) is not enabled and (/dev/shm) is missing
Link to the official documentation: https://help.mikrotik.com/docs/display/ROS/Container
Is it possible to create zabbix-proxy-sqlite3 docker image without using shared memory?
