FYI: I've implemented a PoC of this idea and opened SOLR-15127...
https://issues.apache.org/jira/browse/SOLR-15127 : Date: Fri, 22 Jan 2021 14:37:19 -0700 (MST) : From: Chris Hostetter <hossman_luc...@fucit.org> : To: Solr/Lucene Dev <dev@lucene.apache.org> : Subject: Re: Solr Docker discussion : : : : So I've taken a look at the Elastic docker images [1], and they are : : structured much like official images, except for the use of multi-stage : : builds. They have no ARGs, and the docker context is merely the directory : : in which the Dockerfile sits. With this in mind, and wanting to still take : : advantage of the Official Docker Image, we will likely need to do some sort : : of templating, as Hoss suggested. This can be automated using gradle fairly : : easily I would imagine, and we could ensure that the only changes it makes : : is to the part of the image that downloads Solr. That way there is very : : little room for differences to occur between local and release images. : : If docker-library is willing to allow _/solr:X.Y images that are just : simple 'FROM apache/solr:X.Y' wrappers, and the apache/solr iamges can be : built with multi-stage builds, then i'm not sure we would really need : templating of the Dockerfile -- or to download a solr.tgz file. : : The Dockerfile could have an initial stage that runs "gradle dist" to : compile the java source files -- using a build AEG to override the : default X.Y.Z-SNAPSHOT version variables -- while a later stage could : then take the resulting solr.tgz from the first stage and setup the file : layout for the final image. : : So users wanting to build a "snapshot" docker image from their local : (possibly patched) checkout could just do... : : docker build -f solr/docker/Dockerfile . : : Or from a remote git branch: : : docker build -f solr/docker/Dockerfile https://gitbox.apache.org/repos/asf/lucene-solr.git#branch_9x : : while the official apache/solr:X.Y.Z image would could be reproducibly : buildable via... : : docker build --build-arg SOLR_VERSION=X.Y.Z -f solr/docker/Dockerfile https://gitbox.apache.org/repos/asf/lucene-solr.git#releases/lucene-solr/X.Y.Z : : Same Dockerfile in all use cases, no need for intermediate downloading : from any remote servers. : : : -Hoss : http://www.lucidworks.com/ : -Hoss http://www.lucidworks.com/ --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
