Using this image

Running the container

This docker image is based on cacti0.8.8h. It does not have a database by default. You must use an external mysql database or a mysql database docker image. The database docker image I used in the test environment is million12/mariadb, but this database image cannot modify the time zone. You can also use other mysql images, preferably you can modify the time zone.

Exposed Ports

The following ports are important and used by Cacti

Port Notes
80 HTTP GUI Port
514 SYSLOG Port

It is recommended to allow at least one of the above ports for access to the monitoring system. This is translated by the -p hook. For example

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. **

    -d \
    --name cacti-db \
    -p 3306:3306 \
    --env="MARIADB_USER=cactiuser" \
    --env="MARIADB_PASS=my_password" \

Remember to use the same credentials when deploying cacti image.

Environmental Variable Mysql

In this Image you can use environmental variables to connect into external MySQL/MariaDB database.

Variable Description
MARIADB_USER database user
MARIADB_PASS database password
TIMEZONE timezone

Cacti Deployment

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

    docker run \
    -d \
    --name cacti \
    -p 80:80 \
    -p 514:514 \
    --env="DB_HOST=localhost" \
    --env="DB_PORT=3306 \
    --env="DB_USER=cactiuser" \
    --env="DB_PASSWORD=cactiuser" \
    --env="TIMEZONE=Asia/Shanghai" \
    --env="RRDTOOL_LOGO=CACTI0.8.8h/RRDTOOL1.4.9-BY:Fenei" \
    --env="INITIALIZE_DB=0" \
    -v '/data/cacti/html':'/var/www/html':'rw' \
    -v '/data/cacti/backups':'/var/www/backups':'rw' \
    -v '/data/cacti/export':'/var/www/export':'rw' \

Environmental Variable cacti

In this Image you can use environmental variables to connect into external MySQL/MariaDB database.

Variable Default Description
DB_HOST localhost Remote database connection address, using IP or domain name
DB_PORT 3306 Remote database connection port
DB_USER cactiuser Remote database username
DB_PASSWORD cactiuser Remote database password
TIMEZONE Asia/Shanghai Cacti server time zone, viewable in /usr/share/zoneinfo
RRDTOOL_LOGO DOCKER-CACTI0.8.8h/RRDTOOL1.4.9-BY:Fenei Rrdtool logo, you can modify the watermark on the right side of cacti graphics, be careful not to enter #
INITIALIZE_DB 0 Initialize the database switch, 1 is initialization, 0 is not, the default is 0. Only valid when the cacti database is detected

VOLUME: Mount directory description

File directory description

/var/www/export cacti graphics data export file, automatically export graphics in the number of graphics, including graphics and raw data. The daily flow chart is exported daily, and the monthly monthly flow chart is exported monthly.

Access Cacti web interface

To log in into cacti for the first time use credentials admin:admin. System will ask you to change those when logged in for the firts time.


If realtime has graphics and data, but the graphics list has no data, please use select * from cacti.poller_time; in the mysql database to query the poller time. If the time does not match the cacti server time, you need to modify the mysql database server. Time or use set time_zone = '${mysql_zone}';Modify database time
