PostgreSQL в контейнере выдает ошибку chmod: / var / lib / postgresql / data: операция не разрешена

Я попытался запустить Postgres 12 на docker и следующих файлах, которые я создал. Я не понимаю, где я допустил ошибку и в чем проблема разрешения файла PostgreSQL.

Dockerfile: 

FROM postgres:12.0-alpine
USER root
RUN chmod 0775 /var/lib/postgresql
RUN chown postgres /var/lib/postgresql
USER postgres
# RUN chmod 0775 /var/lib/postgresql
# RUN chown postgres /var/lib/postgresql
RUN ls -l /var/lib/postgresql
# RUN pgctl -D /usr/local/psql/data initdb &&\
RUN initdb -D /var/lib/postgresql/data &&\
    echo "host all  all    0.0.0.0/0  md5" >> /var/lib/postgresql/data/pg_hba.conf && \
    echo "listen_addresses='*'" >> /var/lib/postgresql/data/postgresql.conf && \
    pg_ctl start && \
    psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'test'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE test" && \
    psql --command "ALTER USER postgres WITH ENCRYPTED PASSWORD '123';"
# RUN initdb /var/lib/postgresql/data &&\
#     echo "host all  all    0.0.0.0/0  md5" >> /var/lib/postgresql/data/pg_hba.conf && \
#     echo "listen_addresses='*'" >> /var/lib/postgresql/data/postgresql.conf && \
#     pg_ctl start && \
#     psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'test'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE test" && \
#     psql --command "ALTER USER postgres WITH ENCRYPTED PASSWORD '123';"
# Add VOLUMEs to allow backup of config, logs and databases
VOLUME  ["/etc/postgresql", "/var/log/postgresql", "/var/lib/postgresql"]
EXPOSE 5432

docker - составить .yml 

version: "3.7"
services:
  postgresql:
    build:
      context: .
      dockerfile: ./../postgresql/Dockerfile
    volumes:
      - ../postgresql/db_data:/var/lib/postgresql/data
    ports:
      - 5432:5432

Я выполнил следующую команду в терминале 

docker-compose up

Произошла следующая ошибка.

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

initdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
