Aliasing of EKS endpoint domain

Hello peeps,

Would be aliasing `https://<HASH>.gr7.<region>.eks.amazonaws.com` to a custom CNAME, such as <myClusterName>.<region>.domain to have a predictable endpoint that in turn can be hardcoded in some places a bad practice? Any advice against or in favor of this?

Thank you for your input.

Best options for SLA/SLO tracking outside of data dog

We have very basic needs

Monitor uptime of MongoDB atlas cluster

A few ec2 instances

Need to ping a frontend react app

Need to ping uptime for a graphql api endpoint

That’s about it

I’ve set this up with datadog but worried about the cost, not today, but in two years

Are any other APMs going to be that much cheaper while still doing it all with one account?

How do you track/help onboarding to on-call?

When it comes to something like interviewing, ramping someone to run interviews often involves a process of shadowing for a number of times and some level of feedback before you become officially 'ramped'.

When I've lead teams before, as a team lead I've tracked which incidents people have been involved in, and which services they've touched. But I never had a proper structure to the onboarding, probably because:

- Incident training often requires participating in real incidents, which can’t be scheduled in advance.

- When one does occur, responders want to focus fully on the incident: they don’t want to be searching for an onboarding spreadsheet, making coordinating onboarding a low priority.

- Incidents are varied, as is the way people participate in them, making it difficult to understand what qualifies as ‘training’.

I wondered if people have had more structure than me on this, and if so what and how are they tracking it?

The context is we're considering building this into our product (incident.io) as a concept of onboarding programmes, where you can say:

> You're ramped to handle SRE incidents once you've shadowed the lead for >3 incidents involving either Postgres, ElasticSearch, etc, and led at least one yourself

And want to know how/if people are doing this already.

My mandate is being moved from “DevOps” to “Developer Experience.” Has anyone else made this switch?

Context: Been overseeing the devops for an ecomm company for a little over three years. We brought in a new CTO from a rival startup earlier this year who seems to be way more plugged in to trends in the broader developer community than most of us.

After mentioning “Developer Experience” without much explanation, he’s formally asked me to make it my priority for 2023.

The problem I’m having is there doesn’t even to seem be a crystalized consensus on what “Developer Experience” even means.

From my early research it’s everything from building new CI/CD frameworks to “making sure the developers have the muffins they like.”

Hoping to get any insights you might have on best practices as well as what falls under this responsibility so I can start making a plan.

Branching and deployment strategy for continuous integration

What branching/merging/deployment strategy would you use for a development team of 5 developing a webapp with 10,000 users (not small, not large)?

Currently we have three environments: development, staging, production. Features are developed on feature branches and merged to master, causing an auto-deployment to staging. After smoke testing on staging the developer click-ops to production.

If an issue is discovered on staging, the developer creates a new branch (hotfix) which is merged again to master. There is no way to reverse the feature branch merge to master after the fact.

An added complication: if production ever goes down while the master branch is compromised, the system will auto-deploy the compromised master branch to production.

Also, the development environment is a free-for-all.

There has to be a better approach...

What is the point of having both a develop and a main branch aiming to be in sync?

I often notice teams have both a develop branch from where they pull featurebranches, only for them to merge into develop and then merge into main.

What's the point ? Seems like double bookkeeping to me.

Uptime for MongoDB atlas? No luck with asking atlas and nothing for dátadog integration

Im feeling like I’m just getting poor support and I’m a lazy docs reader, but I can’t seem to find anyway to easily get the uptime of a MongoDB atlas cluster

There is a mongo serverStatus function you can run but you need to run it on each node AND it just tells you the time the mongod process has been running which I’m guessing isn’t going to be the same as “uptime for the cluster” because when a new node is spun up or down, it doesn’t necessarily mean we had downtime (from the experience of a MongoDB atlas cluster consumer/user)

Are people just not measuring SLAs for the DBs lol? How does atlas measure their own SLA lol

NPM version in container environments

I’ve recently begun a new job and found something interesting.

I’ve noticed this pattern where SWEs will make commits to simply bump their package.json version. This of course triggers a new build on their default branch. Then of course the thing they are applying a git tag too isn’t the image that was tested in a lower environment. (We do at least properly promote so there’s not a rebuild on tags).

So I’m curious how do you guys handle apps that are npm apps but are rest apis per se? In the past I’ve just always set the package.json version to 0.0.0 and disregarded it as I prefer the git tags/image tags as the source of truth. Now for npm packages of course the typical process is used.

How do you yaml

A?:

accessModes:
- ReadWriteOnce

or

B?:

accessModes:
- ReadWriteOnce

Personally, I can't even with B. I don't know if it's some sort of chemical imbalance in my brain but I get ultra confused if I see yamls structured this way.

I want to know if I'm the only one or not. No explanation necessary. You do you.

Logic Apps & Workflow Configuration Import into an Azure DevOps CI/CD Pipeline

In my Azure test lab, I currently have a Landing Zone deployed in Terraform via a CI/CD pipeline in Azure DevOps.

I would like to deploy an Azure Logic App, however, I have an existing Logic App workflow config I'd like to import into said Logic App as part of the CICD build process (I was thinking maybe a task or something within the build pipeline?). Moving forward the Workflow configs should then be managed as part of the build pipeline with the config files being hosted in an Azure Repo.

My question is, has anyone ever done this before, and if so what is the best way of going about it? I've spent some time having a go but cannot find the most efficient way of going about it.

TIA :)

Packer + QEMU for Ubuntu 22.04.1 ARM64 ISO

Has someone ever tried creating a custom VM image using Packer + qemu-system-aarch64 with a dedicated Ubuntu 22.04.1 ARM64 ISO image?

I have extensive experience in QEMU and Packer especially for AMD64 and have templates that can boot images using UEFI for x86. However, I found an ISO file from Ubuntu for ARM and you actually have an ISO file there. AFAIK a lot of ARM based devices don't have UEFI implementation and bootloading is not the same as OVMF.

During a Deep-Dive I found a very nice post from Canonical's MAAS called about creating images which provides a fantastic Packer template that is ARM64 / AMD64 interchangeable but only caveat is that it uses Ubuntu's Cloud-Images

I wanted to try the Live Server Image for ARM64

Any expert here in Golden Image Creation can guide me through if this is possible or not?

Is it possible for Password policy implementation in EC2 Ubuntu os level?



I was suggested by PCI-DSS requirement team to implement Password policy on our ec2 ubuntu servers. They have provided us with this link to follow: https://linuxhint.com/secure\_password\_policies\_ubuntu/

But, it's not working after I follow perfectly, still, I can create new passwords randomly for new users. What can be the issue here? Does ec2 really allow to implement of this on the os level?

is there such thing as "encrypting" a repo hosted on Github?

Hello,

I was asked to look into encrypting a github repo hosted on github.com. I understand that all data on github's infra is encrypted since they have all their SOC compliance. Has anyone heard of this before? I'm aware of tools to encrypt individual files but not an entire repo...

Is there any automation solution that isn't "only" CI/CD except Jenkins?

All I want is a solution I can write workflows/pipelines into, arrange them in views and trigger them with parameters (that are more clever than basic strings..), in a way that is better than Jenkins with a better UI. It seems like almost all Devops automation solutions are related mainly to CI/CD, in the sense that they are connected in a 1-to-1 ratio to some code repository. I don't understand why I don't hear people complaining about it more.

My company has much more processes that need automation than CI/CD. We have data-pipelines, DB migrations, on-demand IaC, scheduled tasks, QA pipelines, Customer related pipelines etc.. For each of these we need some other product that is specific to that use case, or some Jenkins invented solution.

I may not be knowledgeable enough in the market, but I'm aware that there are paid solutions. What I'm looking for is something open-source, un-opinionated, mature and container-native. The closest I've come to is argo-workflows, which is an amazing project, but it's just not there yet in terms of front-end/friendliness.

Openshift build/ s2i

I have a fairly good understanding of how s2i works from lab/courses, but I am needing some inputs from the community. Does anyone actually use the functionality for building container images from source repos, or is it all external tools for builds(drone/GH Actions/GitLab etc). My last workplace only deployed prebuild images to openshift from a external private registry.
