Summary: Create hadoop/ozone docker images with inline build
process
Key: HADOOP-16091
URL: https://issues.apache.org/jira/browse/HADOOP-16091
Project: Hadoop Common
Issue Type: New Feature
Reporter: Elek, Marton
This is proposed by [~eyang] in
[this|https://lists.apache.org/thread.html/33ac54bdeacb4beb023ebd452464603aaffa095bd104cb43c22f484e@%3Chdfs-dev.hadoop.apache.org%3E]
mailing thread.
bq. 1, 3. There are 38 Apache projects hosting docker images on Docker hub
using Apache Organization. By browsing Apache github mirror. There are only 7
projects using a separate repository for docker image build. Popular projects
official images are not from Apache organization, such as zookeeper, tomcat,
httpd. We may not disrupt what other Apache projects are doing, but it looks
like inline build process is widely employed by majority of projects such as
Nifi, Brooklyn, thrift, karaf, syncope and others. The situation seems a bit
chaotic for Apache as a whole. However, Hadoop community can decide what is
best for Hadoop. My preference is to remove ozone from source tree naming, if
Ozone is intended to be subproject of Hadoop for long period of time. This
enables Hadoop community to host docker images for various subproject without
having to check out several source tree to trigger a grand build. However,
inline build process seems more popular than separated process. Hence, I
highly recommend making docker build inline if possible.
The main challenges are also discussed in the thread:
{code}
3. Technically it would be possible to add the Dockerfile to the source
tree and publish the docker image together with the release by the
release manager but it's also problematic:
{code}
a) there is no easy way to stage the images for the vote
c) it couldn't be flagged as automated on dockerhub
d) It couldn't support the critical updates.
* Updating existing images (for example in case of an ssl bug, rebuild
all the existing images with exactly the same payload but updated base
image/os environment)
* Creating image for older releases (We would like to provide images,
for hadoop 2.6/2.7/2.7/2.8/2.9. Especially for doing automatic testing
with different versions).
{code}
The a) can be solved (as [~eyang] suggested) with using a personal docker image
during the vote and publish it to the dockerhub after the vote (in case the
permission can be set by the INFRA)
Note: based on LEGAL-270 and linked discussion both approaches (inline build
process / external build process) are compatible with the apache release.
Note: HDDS-851 and HADOOP-14898 contains more information about these problems.
