mULti-cloud kubernetes and whatnot

We’re in the process of deploying everything to multiple cloud providers. We’re already in GCP, AWS is next then Azure. Mostly we’ll be using Kubernetes for the applications and such. For some reason, management wants us looking into the Kubernetes managed services for each provider (EKS, AKS, GKE) which makes no sense to me, really. I think it’d be easier to deploy our own vanilla Kubernetes setup so it’s more “write once, run everywhere”…heh. I know there are tools to abstract out some of the managed specific bits, but I’m still leery.


Anyway, I’m totally open to being wrong, but I’d like to hear from others on which direction they went and why. Preferably from those who have hundreds of applications with 25k+ instances in each provider. Thanks for any insight/links/whatever!

How to implement Blue/Green Deployment using AWS CodePipeline

Hello all,

We, engineers have put together a step-by-step process of implementing Blue/Green Deployment using AWS CodePipeline (including screenshots). Hoping this would be of some use to fellow engineers.

Any constructive feedback or ways to do this any differently are welcome.

How to (or even should I) sell an IPv4 block?

Hey, so we finished our migration to the cloud and we're left with a /24 unused block of IPs our company has had since forever.

Looking around the net I've found a few websites that auction IPs but they do seem a bit dodgy, even more so since we've been receiving random phishy looking emails asking to buy our them every now and then.

Is this a legit market? Can you suggest a website that has worked for you? Any technical considerations we should be mindful of?

How do I solve the lets encrypt rate limit issue with ambassador

Hello everyone please I need help with this. Our ambassador ingress controller generates our tls certs and secrets but a change was made in our environment and it caused an error with the host file so now the rate limit is high. I get an “too many certificates already issued for exact set of domains(10) in the last 168 hours”
I would like to know how lets encrypt counts so I know when we can generate a new one and how can I solve this too please. Does anyone have an idea?

Tree people vs. Forest people

I wrote a post comparing what I call "tree people" to "forest people" and would be interested to hear what y'all think.

tl;dr Forest people are systems people and are disproportionately represented in DevOps. Usually we are right, but sometimes not.

Choosing DevOps machine: MacBook Air M1 or new MacBook Pro with M1 Pro

Do you find that M1 MacBook Air with 16GB of RAM should be enough for DevOps tasks (VS code, IaC tools like terraform or ansible, cli tools, Docker, kubernetes, scripts writing in Powershell, bash, Python, from time to time coding and compiling applications in C#), or should I go with the new MacBook Pro with M1 Pro chip (8CPU/14GPU or 10/16 cores with 16GB RAM)?

Secrets Management Options

So how do you guys manage secrets around the organization and around the app?


So in our current workflow, we deal with typically three types of secrets:
1. shared across the organization such as server access, SSL certs, other common login credentials etc.
2. shared across many projects such as same SMTP credentials, Common API keys etc.
3. shared across many applications in a single project such as DB credentials, API keys etc.


Our typical hierarchy looks like this

1. we have our main org
2. under this, we manage multiple projects (mainly related to client products) and products (our inhouse products)
3. under a single project, there can be multiple applications one for frontend, backend, api, etc.


So currently it's a hassle to manage secrets that's why looking for some elegant solution to manage such secrets.


Any good self-hosted tool is also good to have.

Does anyone here still use openSUSE as a distro? How does it compare to others like Ubuntu or RHEL?

Just curious what the pros/cons are. I am interviewing for a position at SUSE so curious if people still use it and how they like it as a general distro.

When should code get merged to dev?

If you google CI/CD you get a lot of high level theory. And it's a good goal anyway, but a lot of us don't have true ci/cd setup. What I realized is that I don't know what is normal for when code gets merged to dev. Like what is the step by step for a developer. They write code on a branch. I know some people commit often, even if it doesn't work. And others only when it does work. But where does it go from there. Bonus points if you can tie in jira ticket statuses. :)

How to export AWS AMI to OVA/VMX?

I am building an AWS AMI with Packer, I want to export that image, I want to use it on prem, on vmware environment, according to the docs you can export AMI to vmdk, vhd or raw format.

1. Can you somehow export baked AMI directly to OVA? I can export ec2 instance to OVA but that's not what I need at the moment.
2. Can you convert vmdk to ova using Packer somehow? I know you can convert from ova to vmx with Packer.

Ideally, this should be completely automated, which is why I am using Packer. The final result should be a machine image I can deploy to vSphere.

I am a newbie, not sure if this is a right approach.

FluentD vs Logstash

Hello all,

Im doing research on few logging solutions. Ive been looking into ELK vs EFK vs Grafana Loki.

For folks who have experience with using/operating them, I would like some input. More specifically on ELK vs EFK. In which scenarios would you prefer to use? What are advantages/disadvantages over the other? How does it scale? What are its limitations?

Really appreciate all your input. Thank you!

Cloud Architect VS Solutions Architect at AWS

Hi, can anyone please explain to me the difference between a Cloud Architect role VS a Solutions Architect role at AWS?

I am trying to understand the difference between the 2 roles because the job description seems to be identical.

Does one role have an upper hand over the other?

Monitoring Custom App with Grafana

So long i have been using ELK for custom stuff that do not provide a ready prometheus exporters, using a custom script solution that will generate my log which i will send to elk to visualize and monitor.

I would love to understand how i can accomplish the same thing with Grafana and i assume prometheus.

For example, i want to monitor the status of a certain service of mine -only- and some stuff related to that service.

How can one accomplish this? By the way bare metal instance, it's my lab that i am testing these stuff out.
