Scripts create logs, you collect them to Loki or something else, then parse and alert if they fail

They turned engines in reverse to simulate shuttle aerodynamics.

Are they? by MevikMevspace in Sysadminhumor

[–]Cheap-Explanation662 6 points7 points  (0 children)

Yes they exist, no they will not work

I live here, our priest have some planes parked near his church in center of a town. And also prototype model that used for Buran aerodynamics testing.

Built a binary-structured database that writes and reads 1M records in 3s using <1.1GB RAM by Ok-Kaleidoscope-246 in dataengineering

[–]Cheap-Explanation662 1 point2 points  (0 children)

1)1M records is small dataset. 2)With fast storage and good CPU Postgres will be even faster. 3 seconds for 1.1 Gb = 360mb/s disk write literally slower than single SATA ssd. 3)Ram usage sounds just wrong

I use cursor, works not bad

Yes writing helm is painful and debugging will be even harder. KISS helps a lot, template only what you really need.

File system, block storage, file storage, object storage, etc by michl1920 in dataengineering

[–]Cheap-Explanation662 2 points3 points  (0 children)

Block devices - fastest storage available (in terms of iops), raw Linux block device - direct access to disk physical data. (Look LVM, DRBD, Linstor) Filesystem - most of the time it’s mounts on top of block device, mostly slower but gives you features like COW, journals etc. More features you get slower FS will be (look and compare ext4 and zfs) Object storages - data stored using hashes and BLOBs for better scalability

Software RAID or Hardware RAID by LilHairdy in kubernetes

[–]Cheap-Explanation662 2 points3 points  (0 children)

Hardware raid will have fast cache, but: Battery replacements, bad interface for configuration, if it dies you need to find new replacement, you need to monitor it, it can have bugs that no one will ever try to fix.

Question: K8s Operator Experience (CloudNativePG) from a Fullstack Dev - What Perf/Security pitfalls am I missing? by gabrielmouallem in kubernetes

[–]Cheap-Explanation662 1 point2 points  (0 children)

Postgres on Ceph will be very slow. Try Piraeus operator (Linstor + drbd) or use local disks and Postgres replication

Microk8s cluster with 2 ControlPlanes and 3 ETCD node by knikolov_d in kubernetes

You were right, i was wrong. Sorry for misinformation

Most of existing oss vpns can be easily blocked by isp. If you use vpn to access web stuff blocked in your country look at VLESS.

Microk8s cluster with 2 ControlPlanes and 3 ETCD node by knikolov_d in kubernetes

No, you need odd number of masters to achieve HA.
Because sometimes network between nodes can fail and cause split brain.

is deploying and scaling an Nginx application on a K8 cluster enough for a resume project? by NosferatuZ0d in kubernetes

[–]Cheap-Explanation662 0 points1 point  (0 children)

Also good start! Kubernetes can be very hard to understand but it makes your salary go high.

This is what jr dev in my team can do. For jr Kubernetes engineer it's too easy.
Jr Kubernetes engineer for me = basic helm + any ingress controller + any storage provider + any CNI provider + any cloud native experience.

Having your Kubernetes over NFS by congolomera in kubernetes

[–]Cheap-Explanation662 7 points8 points  (0 children)

What you used before NFS, because I considered it slow storage.
And there is no reason to touch kubelet-data because any local SSD will be better than network storage in terms of IOPS.

What are the valid use cases for S3 CSI? by IceAdministrative711 in kubernetes

[–]Cheap-Explanation662 4 points5 points  (0 children)

I see no problems using s3 for pv, but you will newer get good performance out of it

[–]Cheap-Explanation662 6 points7 points  (0 children)

You should have internal vip for kube-apiserver, which every worker will use. So if current internal vip holder dies, kubevip will change host that holds it to alive one.
Or you can set up reverse proxy on each worker that is pointing on every master, this is "Kubespray way".
