feat(deployment): update mysql to 5.7 and support running as nonroot

[juliusvonkohout]

@Bobgy sorry, but the heavy restructuring made it quite pointless to do a manual rebase of #5228

docker.io/mysql:5.7 is an official dockerhub image. So there should not be rate limits AFAIK. But you can of course create gcr.io/ml-pipeline/mysql:5.7 .

metadata-db that you want to merge with this mysql database currently uses mysql:8.0. But ml-pipeline does not work with 8.0

So you should make sure that the metadata stuff works with 5.7 or fix ml-pipeline to work with 8.0 and create gcr.io/ml-pipeline/mysql:8.0 from docker.io/mysql:8.0.

I tested that metadata-db works with mysql:5.7 and all pods are running, but i could not really test the functionallity because https://github.com/kubeflow/metadata/blob/master/sdk/python/sample/demo.ipynb seems to be broken.

Related to kubeflow/manifests#1756

Hi @juliusvonkohout. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Thank you!

In KFP standalone mode, we deploy metadata-db also on 5.7, so I believe you can rest assured it works.

I just created gcr.io/ml-pipeline/mysql:5.7, can you use it instead?

Hmm, would you mind also updating

pipelines/test/tag_for_hosted.sh

Lines 111 to 112 in 9c10d4f

	docker tag gcr.io/ml-pipeline/mysql:5.6 gcr.io/$PROJECT_ID/hosted/$COMMIT_SHA/mysql:$SEM_VER
	docker tag gcr.io/ml-pipeline/mysql:5.6 gcr.io/$PROJECT_ID/hosted/$COMMIT_SHA/mysql:$MM_VER

?

It's for KFP on GCP marketplace.

Done. All test are successful. I just had to add a fix for docker-library/mysql#186
