> Key: SINGA-358
> URL: https://issues.apache.org/jira/browse/SINGA-358
> Project: Singa
> Issue Type: Improvement
> Reporter: James Lamb
> Priority: Trivial
> Labels: Docker
>
> I would like to propose a few changes to the Dockerfiles found in tool/:
> [https://github.com/apache/incubator-singa/tree/master/tool/docker|https://github.com/apache/incubator-singa/tree/master/tool/docker]
> The size of the resulting image can be reduced by making the following
> changes:
> * consolidating all RUN commands into a single RUN layer (reducing the
> number of layers)
> * running {color:#14892c}yum clean all{color} (on CentOS) to clear out the
> package cache
> * running {color:#14892c}conda clean --all{color} (in the conda container)
> to clear out cached package tarballs, abandoned package versions, and other
> build artifacts from all the libraries that are conda installed
> I would also like to propose breaking out package installs onto multiple
> lines for readability (both of the Dockerfile and diffs in git).
> I will be submitting a PR on GitHub shortly. Generating this issue first so I
> can tag my PR to it.
