What is LedgerSMB?

LedgerSMB is a user-friendly accounting and ERP solution for small to mid-size businesses. It comes with support for many languages and support for different locales.

The project aims to be the solution a start-up never outgrows.

How is this image designed to be used?

This image is designed to be used in conjunction with a running PostgreSQL instance (such as may be provided through a separate image).

This image exposes port 5762 running a Starman HTTP application server. We do not recommend exposing this port publicly, because

  1. The Starman author recommends it
  2. We strongly recommend TLS encryption of all application traffic

While the exposed port can be used for quick evaluation, it's recommended to add the TLS layer by applying Nginx or Apache as reverse proxy.

Enabling optional functionalities such as outgoing e-mail and printing could require additional setup of a mail service or CUPS printer service.

How to use this image

This image can be installed either automatically with the Docker compose file manually with docker only.

Docker-Compose installation and start

This image provides docker-compose.yml which can be used to pull related images, install them, establish an internal network for their communications, adjust environment variables, start and stop LedgerSMB. The only instructions required, after the optional edition of the file to adjust the environment variables, are:

 $ docker-compose pull
 $ docker-compose up

Manual installation

Start a postgres instance

 $ docker run -d --name postgres \
              -e POSTGRES_PASSWORD=mysecretpassword \

BEWARE: The command above creates a container with the database data stored inside the container. Upon removal of the container, the database data will be removed too!

To prevent destruction of the database data upon replacement of the container, please use these commands instead:

 $ docker volume create dbdata
 $ docker run -d --name postgres \
              -e POSTGRES_PASSWORD=mysecretpassword \
              -e PGDATA=/var/lib/postgresql/data/pgdata \
              -v dbdata:/var/lib/postgresql/data \

Start LedgerSMB

 $ docker run -d -p 5762:5762 --name myledger \

This command maps port 5762 of your container to port 5762 in your host. The web application inside the container should now be accessible through http://localhost:5762/

Set up LedgerSMB

  • Visit http://myledger:5762/
  • Log in with the "postgres" user and the password mysecretpassword and provide the name of a company (= database name) you want to create.
  • Go over the steps presented in the browser

Once you have completed the setup steps, you have a fully functional LedgerSMB instance running!

Visit http://localhost:5762/ to log in and get started.

Updating the LedgerSMB container

No persistant data is stored in the LedgerSMB container.

All LedgerSMB data is stored in Postgres, so you can stop/destroy/run a new LedgerSMB container as often as you want.

Environment Variables

The LedgerSMB image uses several environment variables. They are all optional.


Default: postgres

Specifies the hostname of the PostgreSQL server to connect to. If you use a PostgreSQL image, set it to the name of that image.


Default: 5432

Port on which the PostgreSQL server is running.


Default: lsmb

Set this if you want to automatically log in to a particular LedgerSMB database without needing to enter the name of that database on the login screen.


Default: 5

Set this if you want to run in a memory-constrained environment. E.g. set it to 2 when running in a 1 GB memory setup. Please do note that this may adversely affect the performance experience of users.

Mail configuration

  • SSMTP_ROOT (config: Root)
  • SSMTP_MAILHUB (config: Mailhub)
  • SSMTP_HOSTNAME (config: Hostname)
  • SSMTP_AUTH_USER (config: AuthUser)
  • SSMTP_AUTH_PASS (config: AuthPass)
  • SSMTP_AUTH_METHOD (config: AuthMethod)
  • SSMTP_FROMLINE_OVERRIDE (config: FromLineOverride)

These variables are used to set outgoing SMTP defaults.

To set the outgoing email address, set SSMTP_ROOT and SSMTP_HOSTNAME at a minimum.

SSMTP_MAILHUB defaults to the default docker0 interface, so if your host is already configured to relay mail, this should relay successfully with only the root and hostname set.

Use the other environment variables to relay mail through a different host. Use the ssmtp.conf man page to look up the meaning and function of each of the mail configuration keys.


Currently the LedgerSMB installation is in /srv/ledgersmb and the startup & config script is /usr/bin/
