Following a discussion with a colleague on Slack, I thought I'd remind myself how OpenLDAP works as a service running inside a container, via the Docker container runtime interface (CRI).
Using this for inspiration: -
I pulled the requisite image from Docker Hub: -
docker pull osixia/openldap:1.5.0 -u davidhay1969:<DOCKER TOKEN>
and created a container: -
docker run --detach -p 3389:389 osixia/openldap:1.5.0
