I do all of this with kubernetes. For VM workloads, I use kubevirt (which is libvirt controlled by kubernetes). It runs extremely well, is lightweight, and it’s very consistent to operate.
At one point I had a lot more layers to this. As I became more competent and aware use the ecosystem, it all flattened into bare metal kubernetes.
Doesn’t seem like a problem unless the gitops controller is managing repositories too.
This isn’t a cyclic dependency, and doesn’t affect failure modes. If the git server fails, the gitops controller fails or waits.
It’s a bit more of a problem if the cluster IaC itself is managed using this git instance, but that’s easy enough to solve with backups or not doing that.
Since this is a home lab, none of this is problematic. Feel free to condense everything - even the backup controller. Just make sure you have a way to access data and manually intervene if it shits the bed.
It would be initially, but then you only have to add one every 100GB. How annoying would it be then?
For me, not very. My data grows by 100GB every few months.
Soundproof it.
Don’t fuck with the fans. Not ever. They’re loud because they’re small. They don’t move much air when they’re quiet. It’s a small oven if the air moves slow.
If your ambient temperature is that close to your operating temperature, you’re going to have to pass a hilarious amount of air across the machine to keep it within range. So don’t do it unless you’re going to blow fans directly at it that are controlled by internal thermostat or are always moving air fast enough.
Not that this is hard. One 6"inline duct blower could do this if you cowl it right.
Make sure your think clients support graphics processing offloading - a very nice feature of RDP that really sets it apart.
A NAS is *way* too easy for even a novice to build to justify buying it as an appliance. Set up a software RAID and filesystem with LVM+XFS or ZFS or bcacheFS. Install the NFS server userspace utilities. Use the in-kernel NFS server. Add a line or two of configuration to /etc/exports.
Done. That’s what, fifteen minutes of work tops?
NextCloud, Plex, Minio (s3, backed by Linstor), NFS CSI driver, Linstor (DRBD), Pacemaker (HA NFS server, backed by Linstor).
Linstor controls the block layer and transport, as well as providing a FS-agnotic replication layer. NFS is used for HDD-backed file storage, and is extremely simple and reliable due to the stateful cluster that controls it. S3 is used by various applications, as it’s easy as hell to implement clients for. S3 has an SSD and HDD tier, as well as an AWS-replicated tier. S3 is where my backups go (Velero).
You can find 12-bay raspberry PI blade chassis that fit in 2U on thingiverse. I had a friend print me one. It’s been wonderful. You can buy them too, of course.
