[SOLVED] How to stop slapd within Dockerfile?

Issue

I try to build my own Docker container with slapd and Dockerfile.

Installation of slapd is OK and then I need to stop slapd in order to add a custom database.
For that I need to run slapadd command on a non running slapd. Nevertheless RUN pkill slapd produces the following error:

Step 7 : RUN service slapd start ; ldapadd -Y EXTERNAL -H ldapi:/// -f xxx.ldif
---> Using cache
---> 53e1e1a59517
Step 8 : RUN pkill slapd
---> Running in efc0058a4bfe
The command '/bin/sh -c pkill slapd' returned a non-zero code: 1

Do you know why and how I can stop properly slapd with Dockefile?

Solution

You are splitting your slapd operations over multiple RUN directives: that is not practical, as each RUN will create an intermediate container, and commit that container as an intermediate image.

It is best to group all your operation in one script, that you COPY first in your image, and then RUN that script.
That way, inside one intermediate container, you can start/stop slapd, add your ldif files, do other tests, before the intermediate container stops and is committed as a new intermediate image.
