Provide and publish ppc64le images

[wohali]

A few requests have come in for ppc64le images, see #66, #60, etc.

This is blocked until:

• Jenkins CI is updated to include an ppc64le build target, see Add multi-platform support to CI configuration couchdb#1121 for progress on this
• CI workflow is "all-green" on a regular basis
• PR Support multi-arch image building for couchdb docker image #60 is merged

Hi @wohali Currently I am pursuing this task. Can I get an update on the progress of this issue??

[wohali]

Still blocked by everything stated in my last update.

[abdasgupta]

Hi @wohali , Can we work to solve the first problem of the list at first? Can I know what is to be done yet to close the first problem?

[wohali]

Start with: If you have access to a ppc64le machine, run make check and confirm that all tests pass. If some fail, log them here:

https://github.com/apache/couchdb/issues

as ppc64le specific failures.

[abdasgupta]

Hi @wohali raised a issue after observing a test case failure: apache/couchdb#1351 I am currently working to progress further.

[abdasgupta]

Hi @wohali So make check is working fine on ppc64le. Can you guide me to next step to bring couchdb on power?

[abdasgupta]

Hi @wohali any update??

[wohali]

@abdasgupta We need to add regression testing on ppc64le so that this good result continues. This requires ASF Jenkins work. Are you an ASF contributor/member?

[abdasgupta]

Hi @wohali , We have two ppc64le nodes on ASF jenkins. Please follow the link, https://issues.apache.org/jira/browse/INFRA-15887 . I am a contributor of Mesos of ASF. Can you please let me know what do I need to do to enable Jenkins CI on ppc64le?

[wohali]

We need to update Jenkinsfile on apache/couchdb to run on this platform.

Currently all builds on Jenkins are done in docker containers themselves to avoid having to install the prerequisites on the Jenkins nodes directly.

Have a look at apache/couchdb-ci and see if you can set up the scripts to build a testing environnment on ppc64le. Pick the OS you think is most supported there - my guess would be Ubuntu 16.04 LTS or possibly 18.04. (I have no access to one of these systems so I can't tell you for sure).

Make a PR on that repo and I'll review the code, and can push an image up to the couchdbdev Docker Hub organisation for the team.

After that, make a PR on apache/couchdb that uses the image in Jenkinsfile. Name your branch jenkins- and we'll be able to test it before it is committed to master.

Once we have proper CI on ppc64le, so we can look at failure situations with every commit to master, I'll greenlight updating this repo to have ppc64le support and we can push an apache/couchdb image that is ppc64le flavoured.

@wohali @abdasgupta
Do we have couchdb support for a ppc64le CI yet? I was checking https://builds.apache.org/job/CouchDB/ and saw that the two ppc64le nodes(ubuntu-ppc64le and hadoop-ppc64le-1) have no Projects tied to them. Please let me know in case I am missing something here.
