LemonLDAP::NG in Docker

Build the image

Use the docker build command:

docker build --rm -t yourname/lemonldap-ng:version .

Run the image

The image will run LemonLDAP::NG in demo mode (see http://lemonldap-ng.org/documentation/latest/authdemo).

Add auth.example.com/manager.example.com/test1.example.com/test2.example.com to /etc/hosts on the host

echo "127.0.0.1 auth.example.com manager.example.com test1.example.com test2.example.com" | sudo tee -a /etc/hosts

Map the container port 80 to host port 80 (option -p) when you run the container to be able to access it

docker run -d -p 80:80 yourname/lemonldap-ng:version

Then connect to http://auth.example.com with your browser and log in with dwho/dwho.

Configuration

You may use the following environment variables to configure the container

• SSODOMAIN: change the default example.com domain with something else
• LOGLEVEL: Set LLNG verbosity (for docker logs). Possible values: error, warn, notice, info, debug
• FASTCGI_LISTEN_PORT: Listen on a port instead of using a UNIX socket. If you use this variable, you will probably want to map this port on your host.
• PROXY_RANGE: if LLNG is running behind a reverse proxy, change the nginx configurations for set_real_ip_from. PROXY_RANGE will be the IP range of your proxy. ex: 172.0.0.0/8

You can also finely set the hostnames for each site

• PORTAL_HOSTNAME: change the default auth.example.com domain with something else
• MANAGER_HOSTNAME: change the default manager.example.com domain with something else
• HANDLER_HOSTNAME: change the default reload.example.com domain with something else
• TEST1_HOSTNAME: change the default test1.example.com domain with something else
• TEST2_HOSTNAME: change the default test2.example.com domain with something else

Example:

docker run -d -e SSODOMAIN=test.local -e LOGLEVEL=debug -p 80:80 yourname/lemonldap-ng:version

Or

docker run -d \
    -e SSODOMAIN=test.local \
    -e PORTAL_HOSTNAME=myportal.test.local \
    -e MANAGER_HOSTNAME=mymanager.test.local \
    -e HANDLER_HOSTNAME=myhandler.test.local \
    -e TEST1_HOSTNAME=mytest1.test.local \
    -e TEST2_HOSTNAME=mytest2.test.local \
    -e LOGLEVEL=debug \
    -e FASTCGI_LISTEN_PORT=9000 \
    -p 80:80 \
    -p 9000:9000 \
    yourname/lemonldap-ng:version

Don't forget to modify your /etc/hosts accordingly
