Reduce image size - Githubissues

use JRE instead of JDK (275 MB). Solr documentation encourages to install JDK for full international charset support, but I'm pretty sure this is an obsolete requirement, see Java 8 Supported Encodings.
don't install lsof (38 MB) which is not needed. By the way, curl and procps are not needed and are already installed. The hole apt-get install command can be entirely removed.

In addition, Solr 5 documentation says you only need a JRE.

Now that we use official java:8 parent image, I'm less concerned about the size premium of the JDK -- you only pay cost that once, and it is shared over other images that reference it. The java:8 doesn't even specify a preference, and I picked that to increase the chances of re-use.

But, I'm not opposed to changing this and follow the docs recommendation explicitly.

It is used here: https://github.com/apache/lucene-solr/blob/trunk/solr/bin/solr#L1321

Ah, handy.
