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.

What is Zabbix web interface?

Zabbix web interface is a part of Zabbix software. It is used to manage resources under monitoring and view monitoring statistics.

Zabbix web interface images

These are the only official Zabbix web interface Docker images. They are based on Alpine Linux v3.23, Ubuntu 24.04 (noble), CentOS Stream 10 and Oracle Linux 10 images. The available versions of Zabbix web interface are:

Zabbix web interface 6.0 (tags: alpine-6.0-latest, ubuntu-6.0-latest, ol-6.0-latest)
Zabbix web interface 6.0.* (tags: alpine-6.0.*, ubuntu-6.0.*, ol-6.0.*)

Images are updated when new releases are published. The image with latest tag is based on Alpine Linux.

Zabbix web interface available in four editions:

• Zabbix web-interface based on Apache2 web server with MySQL database support
• Zabbix web-interface based on Apache2 web server with PostgreSQL database support
• Zabbix web-interface based on Nginx web server with MySQL database support
• Zabbix web-interface based on Nginx web server with PostgreSQL database support

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:

docker 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 zabbix/zabbix-web-nginx-mysql: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, or look at the https://hub.docker.com/r/zabbix/zabbix-web-nginx-mysql/tags/.

Linking the container to Zabbix server

docker 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 zabbix/zabbix-web-nginx-mysql:tag

Linking the container to MySQL database

docker 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 zabbix/zabbix-web-nginx-mysql:tag

Container shell access and viewing Zabbix web interface logs

The docker exec command allows you to run commands inside a Docker container. The following command line will give you a bash shell inside your zabbix-web-nginx-mysql container:

console
$ docker exec -ti some-zabbix-web-nginx-mysql /bin/bash

The Zabbix web interface log is available through Docker's container log:

console
$ docker 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 docker 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!

console
docker 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 zabbix/zabbix-web-nginx-mysql:tag

With Docker Swarm or Kubernetes this works with secrets. That way it is replicated in your cluster!

console
printf "zabbix" | docker secret create MYSQL_USER -
printf "zabbix" | docker secret create MYSQL_PASSWORD -
docker 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 zabbix/zabbix-web-nginx-mysql:tag

The image variants

The zabbix-web-nginx-mysql images come in many flavors, each designed for a specific use case.

zabbix-web-nginx-mysql:alpine-<version>

This image is based on the popular Alpine Linux project, available in https://hub.docker.com/_/alpine. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

To minimize image size, it's uncommon for additional related tools (such as git or bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the https://hub.docker.com/_/alpine/ for examples of how to install packages if you are unfamiliar).

zabbix-web-nginx-mysql:ubuntu-<version>

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

zabbix-web-nginx-mysql:ol-<version>

Oracle Linux is an open-source operating system available under the GNU General Public License (GPLv2). Suitable for general purpose or Oracle workloads, it benefits from rigorous testing of more than 128,000 hours per day with real-world workloads and includes unique innovations such as Ksplice for zero-downtime kernel patching, DTrace for real-time diagnostics, the powerful Btrfs file system, and more.

Supported Docker versions

This image is officially supported on Docker version 1.12.0.

Support for older versions (down to 1.6) is provided on a best-effort basis.

Please see the Docker installation documentation for details on how to upgrade your Docker daemon.
