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 appliance?

Important information:_ Zabbix Docker Appliance image has been decommissioned and will not be available for 3.0.31, 4.0.19, 4.4.7, 5.0.0 and newer releases. Please use a separate Docker image for each component instead of the all-in-one solution.

Zabbix appliance contains MySQL database server, Zabbix server, Zabbix Java Gateway and Zabbix frontend based on Nginx web-server.

How to use this image

Start zabbix-appliance

Start a Zabbix server container as follows:

docker run --name some-zabbix-appliance -p 80:80 -p ***:*** -d zabbix/zabbix-appliance:tag

Where some-zabbix-appliance is the name you want to assign to your container. See the list above for relevant tags, or look at the full list of tags.

Container shell access and viewing Zabbix appliance 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-appliance container:

console
$ docker exec -ti some-zabbix-appliance /bin/bash

The Zabbix appliance logs is available through Docker's container log:

console
$ docker logs some-zabbix-appliance

The image variants

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

zabbix-appliance: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-appliance:alpine-<version>

This image is based on the popular Alpine Linux project, available in the alpine official image. 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 alpine image description for examples of how to install packages if you are unfamiliar).

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.
