i new codenvy user. attempting build "stack" in codenvy run postgres.

i creating stack using following recipe. (using https://github.com/eclipse/che-dockerfiles/blob/master/recipes/ubuntu_jdk8/dockerfile starting point)

this recipe creates codenvy server containing eclipse che, maven, , tomcat.

i need add ant , postgres configuration. able add ant. current challenge adding postgres configuration.

here current recipe.

i found sample dockerfile installs postgres following command

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

when add codenvy stack recipe, see failure when attempt start workspace.

[docker] step 13/13 : run apt-get update && apt-get install -y ant git postgresql-client postgresql-contrib [docker] ---> running in 672fc2aac027 [docker] reading package lists...

what proper way install postgres in environment? once installed, how ensure postgres service started?

one of primary benefits of docker not re-inventing wheel. should use official postgresql image.

if base postgresql image not sufficient needs, inherit , add whatever need on top.

as general rule, if ever building image off ubuntu, think twice because may using wrong tool job.
