snmptraps in docker

[damasu]

well in my case its not like what you have


in my case when i attach to my container and go here

/var/lib/zabbix $ ls -ltr
total 0
drwxr-xr-x 2 root root 6 Jun 4 18:34 snmptraps
drwxrwxr-x 2 zabbix root 6 Jun 4 19:21 mibs

snmptrap is owned by root.



i m using compose yml which is on zabbix git hub https://github.com/zabbix/zabbix-doc...ql_latest.yaml

if you are not mounting a volume then you need to add a chmod to that folder in the Dockerfile as zabbix-snmptraps runs as 1997 user = zabbix

yes so i changed perms in Dockerfile https://github.com/zabbix/zabbix-doc...ine/Dockerfile and tried chmod chown .. nothing works. I even removed all containers , all images , reinstalled images after editing and still perms arr wrong. I just dont know how can i fix this ?

[damasu]

paste your dockerfile

[rajsolanki]

attached is my docker file.

[damasu]

there is no chmod to adjust the folder permissions in that dockerfile! you need to add RUN chown -R zabbix:root /var/lib/zabbix/snmptraps or append to a RUN command.

https://github.com/zabbix/zabbix-doc...ntu/Dockerfile

as an example does it correctly. copy the two lines that are setting group and user permissions on that folder.

[damasu]

nevermind

i see chgrp -R zabbix /etc/snmp/ /var/lib/zabbix/ /var/tmp/ /var/run/ && \
chmod -R 775 /etc/snmp/ /var/lib/zabbix/ /var/tmp/ /var/run/ && \

strange that should be setting the folders correctly report it as a bug

[damasu]

amybe you need to recreate your volume as it is holding old structure

[rajsolanki]

so for just trial i added

chmod -R 777 /var/lib/zabbix/
chmod -R 777 /var/lib/zabbix/snmptraps
chmod -R 777 /var/lib

did

docker stop $(docker ps -aq)
docker rm $(docker ps -aq)
docker rmi $(docker images -q)
and then docker-compose -f docker-compose_v3_alpine_mysql_latest.yaml up -d

you would think it will work right ? but nope.

after i do docker exec to container and do following ownership is still root:root

/var/lib/zabbix $ pwd
/var/lib/zabbix
/var/lib/zabbix $ ls -ltr
total 0
drwxr-xr-x 2 root root 6 Jun 4 18:34 snmptraps
drwxrwxr-x 2 zabbix root 6 Jun 4 19:57 mibs

ok i was able to fix this. So now traps show in snmptrap.log but not in zabbix UI. i even added snmp trap item. damasu does it show up for you in zabbix UI ?

[ankit.k.shrivastava]

Having similar issues with 5.0. Traps show in snmptrap.log and even docker logs but don't show up in the UI.

[ankit.k.shrivastava]

Ok it finally works now
