Description

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 interface images

Images are updated when new releases are published.

The image based on Nginx web server with MySQL database support.

How to use this image

Start zabbix-web-nginx-mysql

Start a Zabbix web-interface container as follows:
podman run --name some-zabbix-web-nginx-mysql
-e DB_SERVER_HOST="some-mysql-server"
-e MYSQL_USER="some-user"
-e MYSQL_PASSWORD="some-password"
-e ZBX_SERVER_HOST="some-zabbix-server"
-e PHP_TZ="some-timezone"
-d registry.connect.redhat.com/zabbix/zabbix-web-mysql-62:tag
Where some-zabbix-web-nginx-mysql is the name you want to assign to your container, some-mysql-server is IP or DNS name of MySQL server, some-user is user to connect to Zabbix database on MySQL server, some-password is the password to connect to MySQL server, some-zabbix-server is IP or DNS name of Zabbix server or proxy, some-timezone is PHP like timezone name and tag is the tag specifying the version you want. See the list above for relevant tags.

Linking the container to Zabbix server

podman run --name some-zabbix-web-nginx-mysql
--link some-zabbix-server:zabbix-server
-e DB_SERVER_HOST="some-mysql-server"
-e MYSQL_USER="some-user" -e MYSQL_PASSWORD="some-password"
-e ZBX_SERVER_HOST="some-zabbix-server"
-e PHP_TZ="some-timezone"
-d registry.connect.redhat.com/zabbix/zabbix-web-mysql-62:tag

Linking the container to MySQL database

podman run --name some-zabbix-web-nginx-mysql
--link some-mysql-server:mysql
-e DB_SERVER_HOST="some-mysql-server"
-e MYSQL_USER="some-user" -e MYSQL_PASSWORD="some-password"
-e ZBX_SERVER_HOST="some-zabbix-server" -e PHP_TZ="some-timezone"
-d registry.connect.redhat.com/zabbix/zabbix-web-mysql-62:tag

Container shell access and viewing Zabbix web interface 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-nginx-mysql container:
$ podman exec -ti some-zabbix-web-nginx-mysql /bin/bash

The Zabbix web interface log is available through Podman's container log:
$ podman logs some-zabbix-web-nginx-mysql

Environment Variables

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

ZBX_SERVER_HOST

This variable is IP or DNS name of Zabbix server. By default, value is zabbix-server.

ZBX_SERVER_PORT

This variable is port Zabbix server listening on. By default, value is 10051.

DB_SERVER_HOST

This variable is IP or DNS name of MySQL server. By default, value is 'mysql-server'

DB_SERVER_PORT

This variable is port of MySQL server. By default, value is '3306'.

MYSQL_USER, MYSQL_PASSWORD, MYSQL_USER_FILE, MYSQL_PASSWORD_FILE

These variables are used by Zabbix web-interface to connect to Zabbix database. With the _FILE variables you can instead provide the path to a file which contains the user / the password instead. Without Docker Swarm or Kubernetes you also have to map the files. Those are exclusive so you can just provide one type - either MYSQL_USER or MYSQL_USER_FILE!
podman run --name some-zabbix-web-nginx-mysql
-e DB_SERVER_HOST="some-mysql-server"
-v ./.MYSQL_USER:/run/secrets/MYSQL_USER -e MYSQL_USER_FILE=/run/secrets/MYSQL_USER
-v ./.MYSQL_PASSWORD:/run/secrets/MYSQL_PASSWORD -e MYSQL_PASSWORD_FILE=/var/run/secrets/MYSQL_PASSWORD
-e PHP_TZ="some-timezone"
-d registry.connect.redhat.com/zabbix/zabbix-web-mysql-62:tag

With Docker Swarm or Kubernetes this works with secrets. That way it is replicated in your cluster!
printf "zabbix" | podman secret create MYSQL_USER -
printf "zabbix" | podman secret create MYSQL_PASSWORD -
podman run --name some-zabbix-web-nginx-mysql
-e DB_SERVER_HOST="some-mysql-server"
-e MYSQL_USER_FILE=/run/secrets/MYSQL_USER -e MYSQL_PASSWORD_FILE=/run/secrets/MYSQL_PASSWORD
-e ZBX_SERVER_HOST="some-zabbix-server"
-e PHP_TZ="some-timezone"
-d registry.connect.redhat.com/zabbix/zabbix-web-mysql-62:tag

This method is also applicable for MYSQL_ROOT_PASSWORD with MYSQL_ROOT_PASSWORD_FILE.
By default, values for MYSQL_USER and MYSQL_PASSWORD are zabbix, zabbix.
