-----------------------------------------
Summary: Dockerfile for local builds that can also serve as
template for 'official' docker images
Key: SOLR-15250
URL: https://issues.apache.org/jira/browse/SOLR-15250
Project: Solr
Issue Type: Sub-task
Reporter: Chris M. Hostetter
Assignee: Chris M. Hostetter
This issue tracks PoC work experimenting with the idea of the following
workflow:
For Users:
* a {{Dockerfile}} (or {{Dockerfile.local}}) in our git repo that can be used
(directly or via gradle) to build docker images directly from a local solr.tgz
(in the docker build context)
For Release Manager:
* The exact same {{Dockerfile}} serves as a "template" that gradle tasks use
to generate a {{build/Dockerfile.official}} via some very simple substitutions
to fill in ARG defaults based on the "official" solr-VERSION.tgz for this
release
* This {{Dockerfile.official}} can then be committed to the docker-solr github
repo (or some similar new 9.x+ repo) and can be build with a a completely empty
build context – in which it downloads (and validates) the official
solr-VERSION.tgz (based on the ARG values that were filled in during the
release)
* Automated tests can help us "validate" that the generated
{{Dockerfile.official}} will work _prior_ to officially publishing release
artifacts, by using a "mock" download server to host the local solr-VERSION.tgz
file
The driving goal being that the Dockerfile used for official {{_/solr}} builds
should be as close as possible to identical to the Dockerfile used for "local"
builds by users – given the constraints put on us by the docker-library team.
