[ckan-dev] Error running solr in a container

I replied to derek (mistakly) private in other email:
Hi Derek
The JTS.jar is to enable the spatial support in solr. If you don't need it,
skip it. Or maybe try to mkdir -p and cp the jar before installing solr,
that way you don't have to deal with restarting the service
About the 404 error,  /solr/select/  should be  /solr/ckan/select/
check solr_url in dev.ini

Derek it might not be documented in ckan documentation since ckan still
oficially uses solr 3 or 4 (?) and you are using solr 5.
