I am developing a web app using play fraework2.6. I am trying to have java8, postgres and nginx in my dockerfile. Here's the docker file:

    FROM ubuntu:14.04



#INSTALL

RUN 

    echo "deb http://dl.bintray.com/sbt/debian /" | tee -a /etc/apt/sources.list.d/sbt.list 

    && sudo apt-get update -y --force-yes  

    && sudo apt-get install -y --force-yes sbt



RUN apt-get update && apt-get -y  upgrade && apt-get -y  install software-properties-common && add-apt-repository ppa:webupd8team/java -y  && apt-get update



RUN (echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections) && apt-get install -y  oracle-java8-installer oracle-java8-set-default



ENV JAVA_HOME /usr/lib/jvm/java-8-oracle

ENV PATH $JAVA_HOME/bin:$PATH

ENV SBT_OPTS="-Xmx2048M"

ENV SBT_OPTS="-XX:MaxPermSize=2048m"



# Add the PostgreSQL PGP key to verify their Debian packages.

# It should be the same key as https://www.postgresql.org/media/keys/ACCC4CF8.asc

RUN apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys B97B0AFCAA1A47F044F244A07FCC7D46ACCC4CF8



# Add PostgreSQL's repository. It contains the most recent stable release

#     of PostgreSQL, ``9.3``.

RUN echo "deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main" > /etc/apt/sources.list.d/pgdg.list



# Install ``python-software-properties``, ``software-properties-common`` and PostgreSQL 9.3

#  There are some warnings (in red) that show up during the build. You can hide

#  them by prefixing each apt-get statement with DEBIAN_FRONTEND=noninteractive

RUN apt-get update && apt-get install -y python-software-properties postgresql-9.3 postgresql-client-9.3 postgresql-contrib-9.3



# Install Nginx

RUN sudo apt-get install -y nginx



# RUN echo "ndaemon off;" >> /etc/nginx/nginx.conf

# Note: The official Debian and Ubuntu images automatically ``apt-get clean``

# after each ``apt-get``



# Run the rest of the commands as the ``postgres`` user created by the ``postgres-9.3`` package when it was ``apt-get installed``

USER postgres



# Create a PostgreSQL role named ``docker`` with ``docker`` as the password and

# then create a database `docker` owned by the ``docker`` role.

# Note: here we use ``&&`` to run commands one after the other - the ````

#       allows the RUN command to span multiple lines.

RUN    /etc/init.d/postgresql start &&

    psql --command "CREATE USER crm_play WITH SUPERUSER PASSWORD 'prod#123';" &&

    createdb -O crm_play crm_play



# Adjust PostgreSQL configuration so that remote connections to the

# database are possible.

RUN echo "host all  all    0.0.0.0/0  md5" >> /etc/postgresql/9.3/main/pg_hba.conf



# And add ``listen_addresses`` to ``/etc/postgresql/9.3/main/postgresql.conf``

RUN echo "listen_addresses='*'" >> /etc/postgresql/9.3/main/postgresql.conf



# Expose the PostgreSQL port

EXPOSE 5432



# Add VOLUMEs to allow backup of config, logs and databases

VOLUME  ["/etc/postgresql", "/var/log/postgresql", "/var/lib/postgresql"]



# Set the default command to run when starting the container

# CMD ["/usr/lib/postgresql/9.3/bin/postgres", "-D", "/var/lib/postgresql/9.3/main", "-c", "config_file=/etc/postgresql/9.3/main/postgresql.conf"]



WORKDIR /java/src/project



RUN sbt update



EXPOSE 9000

ENTRYPOINT ["sbt", "run"]

COPY . /java/src/project

First of all is this the correct way to do this. Also build takes too much of time to build. I am building like this:

docker build -t image:tag .

build downloads all dependencies in sbt and other dependencies mentioned in docker file. After that I run

docker run -it -p 9000:9000 image:tag

It again starts downloading all the dependencies. What I am doing wrong here?
