Full Description

Zabbix-Server (CentOS-7 + Supervisor)

Docker Image with Zabbix Server using CentOS-7 and Supervisor.
Image is using external datbase.
This image is using offcial zabbix-server-2.4 Docker Image as base image.

Installed Plugins

Email Notifications with authorisation
Slack Notifications

PHP-FPM Status /fpm_status

Database deployment

To be able to connect to database we would need one to be running first. Easiest way to do that is to use another docker image. For this purpose we will use our million12/mariadb image as our database.

For more information about million12/MariaDB see our documentation.


docker run \
    -d \
    --name zabbix-db \
    -p 3306:3306 \
    --env="MARIADB_USER=username" \
    --env="MARIADB_PASS=my_password" \

Remember to use the same credentials when deploying zabbix-server image.

Configuration from volume

Full config files can be also used. Environment configs will be overriden by
values from config files in this case. You need only to add /etc/custom-config/

-v /host/custom-config/:/etc/custom-config/

Available files:

File Description
php-zabbix.ini PHP configuration file
zabbix_server.conf Zabbix server configuration file

Zabbix-Server Deployment

Now when we have our database running we can deploy zabbix-server image with appropriate environmental variables set.


docker run \
    -d \
    --name zabbix \
    -p 80:80 \
    -p 10051:10051 \
    --link zabbix-db:zabbix.db \
    --env="ZS_DBHost=zabbix.db" \
    --env="ZS_DBUser=zabbix" \
    --env="ZS_DBPassword=my_password" \

With email settings and Slack integration and custom timezone:

docker run \
    -d \
    --name zabbix \
    -p 80:80 \
    -p 10051:10051 \
    --link zabbix-db:zabbix.db \
    --env="ZS_DBHost=zabbix.db" \
    --env="ZS_DBUser=zabbix" \
    --env="ZS_DBPassword=my_password" \
    --env="" \
    --env="" \
    --env="ZABBIX_SMTP_USER=default.smtp.username" \
    --env="ZABBIX_SMTP_PASS=default.smtp.password" \
    --env="SLACK_WEBHOOK=" \

With MySQL/MariaDB linked container:

docker run \
    -d \
    --name zabbix \
    -p 80:80 \
    -p 10051:10051 \
    --link some-mariadb:db \

Access Zabbix-Server web interface

To log in into zabbix web interface for the first time use credentials

Access web interface under http://docker_host_ip
Follow the on screen instructions.

Zabbix Push Notifications

Zabbix notification script is located in /usr/local/share/zabbix/alertscripts
Please follow Zabbkit manual to configure notifications.

Email Notifications (Server settings)

Using environmental variables on docker run you can edit default email server settings. Valuse would be added on into /usr/local/share/zabbix/alertscripts/
Environmental variables are:

Go into Administration/Media types and add new type using script as Type. Script name should be

Next go to Configuration/Actions and create new action. Select recovery message.

Note: this Slack Integration script is based on one originally developed by ericoc/zabbix-slack-alertscript.
For deatiled installation please see ericoc instructions.

Nginx Status Template

Nginx stats script is located in /usr/local/share/zabbix/externalscripts/.
It's latest version of vicendominguez/nginx-zabbix-template official Zabbix communty repo.
Gathering data is done by which is already installed in this image. User need to install template to be able to use this feature.
Go to Configuration/Templates and select Import and import file located in this repo in templates-files directory called zbx_nginx_template.xml

More details in official documentation here.

PHP-FPM Status Template

PHP-FPM Status template assumes that your Nginx server is configured to serve stats under /fpm_status url and port 80. If you you want to use custom port please edit necessary files.

Example of nginx.conf file:

location /fpm_status {
access_log off;
deny all;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass php-upstream;

Go to Configuration/Templates and select Import and import file located in this repo in templates-files directory called zabbix-php-fpm-template.xml


Docker troubleshooting

Use docker command to see if all required containers are up and running:

$ docker ps

Check logs of Zabbix server container:

$ docker logs zabbix

Sometimes you might just want to review how things are deployed inside a running
container, you can do this by executing a bash shell through docker's

docker exec -ti zabbix /bin/bash

History of an image and size of layers:

docker history --no-trunc=true million12/zabbix-server | tr -s ' ' | tail -n+2 | awk -F " ago " '{print $2}'
