How to create volume to docker container with same user witch run this container?

My jenkins starts 'php' docker container by jenkins user. Inside container any created file has owner root, like 'composer install' will create 'vendor' directory with root owner. So jenkins can't cleanup workspace.

A was add to Dockerfile

RUN useradd -r jenkins
USER jenkins

but container can't start. Logs tell me: 

NOTICE: [pool www] 'user' directive is ignored when FPM is not running as root
NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root
ERROR: Unable to create the PID file (/run/php-fpm.pid).: Permission denied (13)
ERROR: FPM initialization failed

Than, i was tried run inside container

chown jenkins:jenkins * -R

But after build finished, i was get unknown owner for my files:

drwxr-xr-x  3 libstoragemgmt input
drwxr-xr-x  6 libstoragemgmt input

User 'libstoragemgmt' with group 'input'

Perhaps the method explained here would work for you. https://jtreminio.com/blog/running-docker-containers-as-current-host-user/

It involves deleting the internal www-data user and recreating it with the same ID as the host user. In your case that would be the jenkins user ID.

This is the example from the article:

FROM jtreminio/php:7.2

ARG USER_ID=1000
ARG GROUP_ID=1000

RUN userdel -f www-data &&\
    if getent group www-data ; then groupdel www-data; fi &&\
    groupadd -g ${GROUP_ID} www-data &&\
    useradd -l -u ${USER_ID} -g www-data www-data &&\
    install -d -m 0755 -o www-data -g www-data /home/www-data &&\
    chown --changes --silent --no-dereference --recursive \
          --from=33:33 ${USER_ID}:${GROUP_ID} \
        /home/www-data \
        /.composer \
        /var/run/php-fpm \
        /var/lib/php/sessions

USER www-data
