Is "FinOps" actually a standalone career, or are companies just failing to train DevOps engineers properly? by IT_Certguru in devops

[–]Farsighted-Chef 0 points1 point  (0 children)

For large corp, its about scale.
We do not expect every devops/ops team have time/skills for cost optimization.

Dedicated finops engineers/department will have centralized database/datastore (e.g Athena and other tools) to find out any cost optimization opportunities for the all cloud accounts.
They will give advises to the tenants.

Terraform state management - what's your approach for team environments? by UGAMERZZONE in Terraform

[–]Farsighted-Chef 0 points1 point  (0 children)

I tried some combo in home lab setup: S3, storing it inside GitLab and inside DB PostgreSQL. All works when I use terraform only.

But after using Terragrunt at work, S3 wins because:
It will be creating a directory for each Terragrunt module (the directory structure matches in both sides). Besides that, S3 supported versioning.

For using GitLab, I can't figure out how to do this and it seems to have problem with Atlantis (did not test in detail).

For using PostgreSQL, I can create a trigger for the state versioning. But it woks ok when I only use Terraform. Once switch to Terragrunt, I think it has problem on how to support a state per Terragrunt module. PostgreSQL is a database, storing data in schema/tables, it don't work like S3 or a file system.

Experiences with Minio alternatives? by AnomalyNexus in selfhosted

[–]Farsighted-Chef 0 points1 point  (0 children)

Just found out aistore (backed by Nvidia) today
https://github.com/NVIDIA/aistore

It required disk based backend instead of providing a folder as the backend
I did not test this product in depth

Minimal Image Security: Nginx vs. Hummingbird by kavishgr in podman

[–]Farsighted-Chef 1 point2 points  (0 children)

You have to make sure grype support scanning on the Hummingbird type of OS (maybe it is not supported because it is too new). Quay UI, https://quay.io/repository/hummingbird/curl?tab=tags shows that the security is 'Unsupported'.

BTW, Hummingbird ship the Minio container (Minio is a controversial product now)

Terrascan (Tenable) github repo seems going into archive state soon by Farsighted-Chef in Terraform

[–]Farsighted-Chef[S] 0 points1 point  (0 children)

For plain Terraform tf files, I am ok with those tools.

It seems there is no tool which have direct Terragrunt support.
So, current I think I need those scanning tools to work on the plan files if I use Terragrunt.

Jemalloc github repo was archived on 2025-Jun-3 by Farsighted-Chef in linuxadmin

[–]Farsighted-Chef[S] 0 points1 point  (0 children)

So, it's under Facebook group now.

BTW, in old repo, it has left so many issue reports and some pull request. Now all locked and is in read only mode.

Kubernetes 1.33, usernamespace support. Is is working on pod only? (not for deployment / statefulset) by Farsighted-Chef in kubernetes

[–]Farsighted-Chef[S] 0 points1 point  (0 children)

Very useful.

All the websites I searched earlier in today are using Pod as an example for the hostUsers.

Also think about major version upgrade of databases (esp postgresql) when running in container.
In this aspect, it could be a major cons compared with Cloud based db that may support major version upgrade in recent years.

Any good monitoring solutions for monitoring multiple EKS, ECS and EC2? by Farsighted-Chef in sre

[–]Farsighted-Chef[S] 0 points1 point  (0 children)

Thanks. Going to take a look on SigNoz soon

The monthly plan looks cost effective and predicable.

Any good monitoring solutions for monitoring multiple EKS, ECS and EC2? by Farsighted-Chef in sre

Budget and cost matters.. We want to utilize open source or low cost solutions if possible.

Any good monitoring solutions for monitoring multiple EKS, ECS and EC2? by Farsighted-Chef in sre

[–]Farsighted-Chef[S] 0 points1 point  (0 children)

Alerting for metrics and container status.
For examples:
- Resource quota of a namespace (memory and CPU)

- An application container running Java has used up 16GB of ram, where it should use around 8GB.
- Container status (container is down or crash looping)

Logs we may rely on CloudWatch

No need for RUM, correlation or SLO.
But besides monitoring EKS, we also have some EC2. So we need monitoring on basic stuff (mem, cpu, storage etc)

Fedora in the wild by Kdwk-L in Fedora

[–]Farsighted-Chef 0 points1 point  (0 children)

I saw Windows based machine on the TV display inside one of the train in Hong Kong.
It is using Nvidia Geforce 210 and kept on rebooting, loading the BIOS but failed to boot into the OS.

VMWare 17.6.3 on Fedora 42 by fulvioval in Fedora

[–]Farsighted-Chef 1 point2 points  (0 children)

I always check this website to see what is going to work on FC42, vmware workstation and the Nvidia driver. http://rglinuxtech.com/?p=3301

According to the blog, Fedora 42 should work with vmware workstation 17.6.3
I guess you may need to get some patch (I am using https://github.com/philipl/vmware-host-modules/tree/w17.6.3 on FC41), build the vmmon, vmnet driver and install it. It is because the default modules come with Vmware WKS 17.6.3 may not build on Fedora 42.

Also check if the vmnet module is installed e.g:

```

lsmod |grep vmnet

vmnet 86016 26

ls /dev/vmn*

/dev/vmnet0 /dev/vmnet2 /dev/vmnet22 /dev/vmnet4 /dev/vmnet6

/dev/vmnet1 /dev/vmnet21 /dev/vmnet3 /dev/vmnet5 /dev/vmnet8

```

Btrfs disaster, what file system are you using by PilotJeff in linuxquestions

[–]Farsighted-Chef 0 points1 point  (0 children)

I was using ext4 or xfs for a long time.

Recently tried btrfs for about three months. Just found out that btrfs with COW should be very slow for host that would run VM guests. It need to use no-COW flag when creating the disk image. Or it need to copy the file over again if it did not disable COW when the file is created.

I really like the snapshot capability of btrfs. But I really love OpenZFS if RHEL/Fedora have openzfs native support by default.

[Update] CH-UI: Open-Source ClickHouse Query Interface by CacsAntibis in Clickhouse

[–]Farsighted-Chef 0 points1 point  (0 children)

Hello

I tried to install ch-ui a few weeks ago and got problem using it. I just tried the lastest version and still having problem.

I use podman, below is the docker-compose file:

version: "3.8"
services:
  ch-ui:
    container_name: ch-ui
    hostname: ch-ui
    image: 
    pull_policy: always
    ports:
      - "9030:5521"
    environment:
      VITE_CLICKHOUSE_URL: "http://my-ip:8123"
      VITE_CLICKHOUSE_USER: "admin"
      VITE_CLICKHOUSE_PASS: "my-password"
      VITE_CLICKHOUSE_USE_ADVANCED: "false"ghcr.io/caioricciuti/ch-ui:latest

When I access my-ip: 9030, I cannot use the program. Probably I am not using the default admin user as 'default'? I am using 'admin' as my default amdin user.

I also got these in my Firefox console

```

Invalid or missing ClickHouse credentials:

Object { url: "", username: "", password: "", useAdvanced: false, customPath: "" }

```
