# 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 v3.4, Ubuntu 14.04 (trusty) and CentOS 7 images. The available versions of Zabbix web interface are:
|
|
|
|

|
|
|
|
Zabbix web interface available in four editions:
|
|
- Zabbix web-interface based on Apache2 web server with MySQL database support
|
|

|
|
- Zabbix web-interface based on Nginx web server with PostgreSQL database support
|
|

# How to use this image
|
|
|
|
## Start `zabbix-web-apache-pgsql`
|
|
|
|
Start a Zabbix web-interface container as follows:
|
|
|
|
docker run --name some-zabbix-web-apache-pgsql -e DB_SERVER_HOST="some-postgres-server" -e POSTGRES_USER="some-user" -e POSTGRES_PASSWORD="some-password" -e ZBX_SERVER_HOST="some-zabbix-server" -e PHP_TZ="some-timezone" -d zabbix/zabbix-web-apache-pgsql:tag
|
|
|
|
Where `some-zabbix-web-apache-pgsql` is the name you want to assign to your container, `some-postgres-server` is IP or DNS name of PostgreSQL server, `some-user` is user to connect to Zabbix database on PostgreSQL server, `some-password` is the password to connect to PostgreSQL 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 [full list of tags](https://hub.docker.com/r/zabbix/zabbix-web-apache-pgsql/tags/).
|
|
|
|
## Linking the container to Zabbix server
|
|
|
|
docker run --name some-zabbix-web-apache-pgsql --link some-zabbix-server:zabbix-server -e DB_SERVER_HOST="some-postgres-server" -e POSTGRES_USER="some-user" -e POSTGRES_PASSWORD="some-password" -e ZBX_SERVER_HOST="some-zabbix-server" -e PHP_TZ="some-timezone" -d zabbix/zabbix-web-apache-pgsql:tag
|
|
|
|
## Linking the container to PostgreSQL database
|
|
|
|
docker run --name some-zabbix-web-apache-pgsql --link some-postgres-server:postgres -e DB_SERVER_HOST="some-postgres-server" -e POSTGRES_USER="some-user" -e POSTGRES_PASSWORD="some-password" -e ZBX_SERVER_HOST="some-zabbix-server" -e PHP_TZ="some-timezone" -d zabbix/zabbix-web-apache-pgsql: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-apache-pgsql` container:
|
|
|
|
```console
|
|
$ docker exec -ti some-zabbix-web-apache-pgsql /bin/bash
|
|
```
|
|
|
|
The Zabbix web interface log is available through Docker's container log:
|
|
|
|
```console
|
|
$ docker logs some-zabbix-web-apache-pgsql
|
|
```
|
|
|
|

# The image variants
|
|
|
|
The `zabbix-web-apache-pgsql` images come in many flavors, each designed for a specific use case.
|
|
|
|
## `zabbix-web-apache-pgsql: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-apache-pgsql:alpine-<version>`
|
|
|
|
This image is based on the popular [Alpine Linux project](http://alpinelinux.org), available in [the `alpine` official image](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](http://www.musl-libc.org) instead of [glibc and friends](http://www.etalabs.net/compare_libcs.html), 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](https://news.ycombinator.com/item?id=10782897) 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](https://hub.docker.com/_/alpine/) 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](https://docs.docker.com/installation/) for details on how to upgrade your Docker daemon.
