Hello everyone,
As pointed out earlier this month in IRC wikimedia-k8s-sig, next week's Kubernetes SIG meeting has already a topic that was brought in by management and it is the usage of Alpine images in our production workloads.
Since that IRC message and today, Ben Tullis has been gracious enough to share some information regarding that. I am summarizing below for the group's convenience so that interested parties show up prepared
https://phabricator.wikimedia.org/T303381 is the driver for this, as it took me six months to get the upgrade to DataHub done: https://phabricator.wikimedia.org/T329514. The idea for alpine was just one possible solution of how we could have gotten around the issues with the build process described in the task above. However, now the datahub building scripts are now effectively unforked from upstream, allowing significant progress in building it with Blubber and Debian from pristine sources. I am much happier with things as they are right now.
While the immediate problem that led to this request seems to have been addressed adequately, I think that we have much to gain as a group discussing this as we can disseminate knowledge abouts pros and cons, in a variety of fields, regarding the type of images we choose and document our discussion and findings in more permanent form that can be easily referred to in the future.
Regards,
