Add postgres to a Codenvy Stack Recipe (dockerfile)

I am a new Codenvy user. I am attempting to build a "Stack" in Codenvy that will run postgres.

I am creating my Stack using the following recipe. (Using https://github.com/eclipse/che-dockerfiles/blob/master/recipes/ubuntu_jdk8/Dockerfile as a starting point)

This recipe creates a Codenvy server containing Eclipse Che, Maven, and Tomcat.

I need to add Ant and Postgres to this configuration. I was able to add Ant. My current challenge is adding Postgres to this configuration.

Here is my current recipe.

FROM eclipse/stack-base:ubuntu
EXPOSE 4403 8000 8080 9876 22

LABEL che:server:8080:ref=tomcat8 che:server:8080:protocol=http 
che:server:8000:ref=tomcat8-debug che:server:8000:protocol=http 
che:server:9876:ref=codeserver che:server:9876:protocol=http

ENV MAVEN_VERSION=3.3.9 \
    ANT_VERSION=1.10.1 \
    JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64 \
    TOMCAT_HOME=/home/user/tomcat8 \
    TERM=xterm
ENV M2_HOME=/home/user/apache-maven-$MAVEN_VERSION
ENV ANT_HOME=/home/user/ant-$ANT_VERSION
ENV PATH=$JAVA_HOME/bin:$M2_HOME/bin:$ANT_HOME/bin:$PATH

RUN mkdir /home/user/tomcat8 /home/user/apache-maven-$MAVEN_VERSION 
$ANT_HOME && \
    wget -qO- "https://www.apache.org/dist/ant/binaries/apache-ant-$ANT_VERSION-bin.tar.gz" | tar -zx --strip-components=1 -C $ANT_HOME && \
    wget -qO- "http://apache.ip-connect.vn.ua/maven/maven-3/$MAVEN_VERSION/binaries/apache-maven-$MAVEN_VERSION-bin.tar.gz" | tar -zx --strip-components=1 -C /home/user/apache-maven-$MAVEN_VERSION/ && \
    wget -qO- "http://archive.apache.org/dist/tomcat/tomcat-8/v8.0.24/bin/apache-tomcat-8.0.24.tar.gz" | tar -zx --strip-components=1 -C /home/user/tomcat8 && \
    rm -rf /home/user/tomcat8/webapps/* && \
    echo "export MAVEN_OPTS=\$JAVA_OPTS" >> /home/user/.bashrc

I found a sample dockerfile that installs postgres with the following command

RUN apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib

When I add this to my Codenvy Stack recipe, I see a failure when I attempt to start my workspace.

[DOCKER] Step 13/13 : RUN apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib
[DOCKER] ---> Running in 672fc2aac027

[DOCKER] 
[DOCKER] [ERROR] Failed to build image: The command '/bin/sh -c apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib' returned a non-zero code: 100

What is the proper way to install postgres in this environment? Once it is installed, how do I ensure that the postgres service is started?

One of the primary benefits of Docker is not re-inventing the wheel. You should use the official PostgreSQL image.

If the base PostgreSQL image is not sufficient for your needs, inherit from it and add whatever you need on top.

As a general rule, if you are ever building your image off ubuntu, think twice because you may be using the wrong tool for the job.

I resolved this issue with help from codenvy repo on GitHub.
