What is Zabbix?

Zabbix is an enterprise-class open source distributed monitoring solution.

Zabbix is software that monitors numerous parameters of a network and the health and integrity of servers. Zabbix uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. Zabbix offers excellent reporting and data visualisation features based on the stored data. This makes Zabbix ideal for capacity planning.

Zabbix web service images

Images are updated when new releases are published.

How to use this image

Start zabbix-web-service

Start a Zabbix web service container as follows:

podman run \
    --name some-zabbix-web-service \
    -e ZBX_ALLOWEDIP="some-zabbix-server" \
    --cap-add=SYS_ADMIN \
    -d registry.connect.redhat.com/zabbix/zabbix-web-service-74:tag

Where some-zabbix-web-service is the name you want to assign to your container, some-zabbix-server is IP or DNS name of Zabbix server and tag is the tag specifying the version you want.

Connects from Zabbix server in other containers

This image exposes the standard Zabbix web service port (10053) to perform communication, so container linking makes Zabbix web service instance available to Zabbix server containers. Start your application container like this in order to link it to the Zabbix web service container:

$ podman run \
    --name some-zabbix-server \
    --link some-zabbix-web-service:zabbix-web-service \
    -e ZBX_STARTREPORTWRITERS="2" \
    -e ZBX_WEBSERVICEURL="http://some-zabbix-web-service:10053/report" \
    -d zabbix/zabbix-server:latest

Container shell access and viewing Zabbix web service logs

The podman exec command allows you to run commands inside a Podman container. The following command line will give you a bash shell inside your zabbix-web-service container:

$ podman exec -ti some-zabbix-web-service /bin/bash

The Zabbix web service log is available through Podman's container log:

$ podman logs some-zabbix-web-service

Environment Variables

When you start the zabbix-web-service image, you can adjust the configuration of the Zabbix web service by passing one or more environment variables on the podman run command line.

• 0 - basic information about starting and stopping of Zabbix processes;
• 1 - critical information
• 2 - error information
• 3 - warnings
• 4 - for debugging (produces lots of information)
• 5 - extended debugging (produces even more information)

ZBX_TIMEOUT

The variable is used to specify timeout for processing requests. By default, value is 3.

Other variables

Additionally the image allows to specify many other environment variables listed below:

ZBX_TLSACCEPT=unencrypted
ZBX_TLSCAFILE=
ZBX_TLSCA=
ZBX_TLSCERTFILE=
ZBX_TLSCERT=
ZBX_TLSKEYFILE=
ZBX_TLSKEY=
ZBX_IGNOREURLCERTERRORS=0

Default values of these variables are specified after equal sign.

Please use official documentation for zabbix_web_service.conf to get more information about the variables.

Allowed volumes for the Zabbix web service container

/var/lib/zabbix/enc

The volume is used to store TLS related files. These file names are specified using ZBX_TLSCAFILE, ZBX_TLSCERTFILE and ZBX_TLSKEYFILE variables. Additionally it is possible to use environment variables ZBX_TLSCA, ZBX_TLSCERT and ZBX_TLSKEY with plaintext values.
