Quick start

This image is based on osixia/openldap please refer to:Β 

Here just the backup extension will be described.

Backup directory and data persistence

Backups are created in the directory /data/backup that should be mapped has volume so your ldap files are saved outside the container.

  docker run --env LDAP_BACKUP_CONFIG_CRON_EXP="0 5 * * *" \
  --volume /data/openldap/backup:/data/backup \
  --detach osixia/openldap-backup:1.5.0

For more information about docker data volume, please refer to :


The container default log level is info. Available levels are: none, error, warning, info, debug and trace.

Example command to run the container in debug mode:

docker run --detach osixia/openldap-backup:1.5.0 --loglevel debug

See all command line options:

docker run osixia/openldap-backup:1.5.0 --help

Environment Variables

Environment variables defaults are set in image/environment/default.yaml.

See how to set your own environment variables

  • LDAP_BACKUP_CONFIG_CRON_EXP: Cron expression to schedule OpenLDAP config backup. Defaults to 0 4 * * *. Every days at 4am.

  • LDAP_BACKUP_DATA_CRON_EXP: Cron expression to schedule OpenLDAP data backup. Defaults to 0 4 * * *. Every days at 4am.

  • LDAP_BACKUP_TTL: Backup TTL in days. Defaults to 15.

Set your own environment variables

Use command line argument

Environment variables can be set by adding the --env argument in the command line, for example:

docker run --env LDAP_BACKUP_CONFIG_CRON_EXP="0 5 * * *" \
--detach osixia/openldap-backup:1.5.0

Link environment file

For example if your environment file is in : /data/ldap/environment/my-env.yaml

docker run --volume /data/ldap/environment/my-env.yaml:/container/environment/01-custom/env.yaml \
--detach osixia/openldap-backup:1.5.0

Take care to link your environment file to /container/environment/XX-somedir (with XX < 99 so they will be processed before default environment files) and not directly to /container/environment because this directory contains predefined baseimage environment files to fix container environment (INITRD, LANG, LANGUAGE and LC_CTYPE).

Make your own image or extend this image

This is the best solution if you have a private registry. Please refer to the Advanced User Guide just below.

Advanced User Guide
