[FEAT]: Arm64 support

[aleksasiriski]

This is written in Go, it should be 1h tops to add arm64 support to the container image. Please do this.

Hey @aleksasiriski - having operator itself in ARM is easy. But there are other components: mongodb itself, percona monitoring and management, backup tooling. We need to have these containers as ARM as well.

Or maybe I misunderstood and for some reason you need operator image only. Please let me know.

Anyway, we have it in our roadmap and it might come out in Q1'24.

@aleksasiriski shall we close this or do you want to keep it open till we have ARM builds for Percona Server for MongoDB and Backup (PBM)?

[aleksasiriski]

However you want it, if those other components have their own repos than this issue shouldn't be linked to them IMO. Thank you for pushing for ARM64 support, hope it gets fully supported ASAP.

@aleksasiriski Both percona-server-mongodb as well as percona-backup-mongodb now have support arm64. It's only missing in the operator.

Wouldn't this pr-1356 support it now? How about a 1.16 release?

[aleksasiriski]

+1 For the new release of operator with support for Arm :D

[Coennie]

any progress news on the 1.16 release? Would really love to get arm supported

Hello @Coennie,

1.16 is out now I believe.

https://docs.percona.com/percona-operator-for-mongodb/RN/Kubernetes-Operator-for-PSMONGODB-RN1.16.0.html#support-for-arm-architecture-technical-preview

thought I am not sure why this is in technical preview??
are there still issues with using this in production ??
@spron-in ??

please avoid currently upgrading and moving to arm,

we found out the hard way that currently pmm client doesn't support arm yet.

Running operator via helm on aarch64 (Oracle Cloud Infrastructure) and it tries to run x86_64 mongod 😭

fixed that with --set image.tag="7.0.8-5-multi" (same tag as it was already using, but the multiarch manifest. No idea why this isn't the default)

However, now backup-agent is the one failing, and looking in the tags there doesn't seem to be a similar solution for backup.image

Also, lifehack:

kubectl -n percona-mongodb patch perconaservermongodb.psmdb.percona.com/butthole-mongodb-psmdb-db -p '{"metadata":{"finalizers":[]}}' --type=merge

helps when deleting your namespace/release deadlocks because it wants to do something in the unexecable containers

Hey all. Sorry for not updating this thread :)

Updates: ARM support was added in 1.16 in tech preview.
PMM client does not support ARM yet, it is true. For users who are using PMM, please wait till PMM is released in Q3/Q4.

@DevBey "thought I am not sure why this is in technical preview??"
It is in tech preview as we need to capture more feedback. We keep high blast radius features in tech preview for at least one release. And there are multiple questions about ARM, which tells me we still have more work to do.

@aleksasiriski it is in 1.16.

Regarding -multi tag - in the following releases of Percona Server for MongoDB and Percona Backup for MongoDB there will be no need to use -multi tag for ARM, as we will make both images multi-arch.

Some details regarding using -multi were discussed here: https://forums.percona.com/t/mongo-operator-and-arm/24326/7

@qm3ster it might help with your problem as well.
