How to run all pods with specific user in Openshift Container Platform 3?

Issue

• In OCP 3.3.0.32 environment run pods with different IDs. Example: Project A runs with uid 100013000 and Project B runs with uid 100014000. How to run pods with a specific user?

• I did the changes in the Dockerfile in order to put the user in the /etc/passwd

RUN useradd -u 1001 -r -g 0 -d /var/lib/test -s /sbin/nologin -c "test example" example

• But we get a getpwuid error:

The message “KeyError: 'getpwuid(): uid not found: 1000340000'”

• How can I correctly write the Dockerfile in order to deploy successfully my pp in OpenShift with custom UID
