Learning one cloud provider or multiple?

Is it better to invest X amount of time into learning one cloud provider or the same amount of time into 2?

Obviously with the first option I would know it more in depth, but the second could make it easier while job searching right?

Also, is there that much info when it comes to each provider? GKS & EKS should work similar enough (it's the k8s themselves that you work with most of the time), then the IAM management (probably the biggest differences here) & then storage management. It's not like I need to be an expert in the provider to do devops, I only need to know the relevant parts...

Multi Cloud soultions & suggestions

I am looking for a solution(s) that can handle CI/CD for multi-cloud and possibly something that can suggest if moving to other plublic might save money.

So for example: If an application is deployed in AWS but maybe deploying in Azure might be cheaper. I would like to get suggestions and approximately how much savings.

For handling multicloud, I'd like the solution to have
1. Be able to deploy to multiple public clouds at once
2. Be able to deploy to other public clouds if application is down

Are there any sort of solution for the above?

I tried AWS Serverless monitoring with Dashbird - here's my honest review

As a startup, we always want to focus on the most important thing — to deliver value to our customers. For that reason, we are a huge fan of the serverless options provided by AWS (Lambda) and GCP (Cloud Function).

Monitoring the execution of the Lambda function starts to become a real issue when you have tens or hundreds of functions running at the same time. When we first started, we relied a lot on Cloudwatch Logs. Instead of creating a serverless monitoring tool ourselves, we were exploring off-the-shelf monitoring options in the market. Dashbird.io was one of services we explored. In this article, I will share the experience of using Dashbird.io, particularly on the onboarding process and the main offering by the platform: https://aws.plainenglish.io/aws-serverless-monitoring-using-dashbird-io-4714fe222e2a

Heroku and DevOps

A new client is intent on hosting production on Heroku. Is this as impractical as it sounds to me and do any of you have anything good or confidence building to say about it?

I'm worried about scaling and being tied into a PaaS that seems to be extremely heavy handed at config.

Seems like setting up CI/CD is pretty easy.

GitLab Commit 2021 - DevSecOps - Upgrade your development workflow with interactive code maps

Earlier this week, I gave a talk at GitLab Commit 2021 about how we can build our understanding of code, share that knowledge with other people, and use new tools for guidance and navigation as we create, fix and improve code. If you weren’t able to attend the event, I’m going to recap my talk here. If you prefer to watch vs. read, scroll down for a 14 minute video of my talk.

Here’s the problem I outlined:

> Acquiring knowledge about code is hard. And communicating it across teams is even harder.

So when we make structural changes to code, I think it’s important to pause for a minute and confirm our assumptions before we start changing things. Getting extra context and getting oriented is really important when making performance changes, refactoring or fixing tough bugs -- because navigation of code becomes less apparent when we make these types of complex changes.

This is particularly relevant in DevSecOps, because security has specific skill sets and values. Bringing security into DevSecOps requires everyone to learn more about people in adjacent roles, and learn a bit of their language and value system in order to collaborate and share context efficiently.

Here’s the example I shared:

Take the lifecycle of a bug fix, a basic communication process that happens every day between 3 different people in different roles. You’ve got:
1. The person reporting the bug (e.g. another developer, a QA tester or security tester)
2. The developer fixing the bug
3. The code reviewer

There are 2 handoff stages here: from the bug finder to the developer, and from the developer to the reviewer. At each stage, a knowledge transfer needs to happen between people with very different experience levels with the code in question. In fact, it’s possible that none of these 3 people really know this particular area of the codebase that well. But they all need to work together to get a code change written, reviewed and approved.

The bug finder knows that the dev team wants as much descriptive information about the bug as possible -- what the tester was doing, what they typed in, what buttons they pushed, what they saw, etc. This description can be accompanied by some screenshots and for UI bugs, this works great. But what about bugs in application behavior, where it’s the backend that’s misbehaving? Maybe the user is presented with inaccurate information or data belonging to someone else! Or they expect to go to page X but end up on page Y. What then?

Here’s the solution I proposed:

As a developer, wouldn’t it be great if the bug finder could send you the equivalent of a screenshot, but of the backend internals? How about a map of code paths, including all the dynamic and complex stuff like HTTP requests, caching, user session interactions, security and SQL?

This is all possible with code maps. And by code maps, I mean a visual presentation of code (other than the code as text) that makes a design aspect of the code easier to understand.

Making code maps is possible with AppMap, a free, open source tool that makes runtime recordings of code. AppMap works equally well with large and small projects, web applications, and microservices. It captures all the information I described above, and bundles it into a portable JSON format. It’s also easy to write programs that process, analyze and display AppMap data.

> Quick sidebar: Last week we released a GitLab integration for AppMap! Now you can upload AppMaps to the AppMap Cloud and log in with your GitLab account. You can also attach links to AppMaps stored in AppMap Cloud to your GitLab merge requests. Here’s a short demo video if you’d like to see this in action.

Here’s the demo I gave:

In my talk, I showed how to use AppMaps to transfer information about bugs from testers to developers, and from developers to code reviewers. Start

watching at the 5:00 mark in the video to watch the demo.

Next steps you can take:

If you’d like to try using code maps to accelerate code understanding and improve communication with your team, you’ll need to:

[Install AppMap](https://appland.com/docs/quickstart/) for VSCode or JetBrains
Install and configure the AppMap client agent for Ruby, Python, or Java
Show your dev team or pen testers how to run the app with AppMap enabled, and use the AppMap browser extension to [record what they see and do](https://appland.com/docs/reference/remote-recording.html)
Show everyone how to upload and download AppMaps - from your own internal repository, or from AppMap Cloud

AWS: Connect to EC2 instances using Systems Manager (SSM)

Hey everyone,

I'm sharing this video to show you how to securely access your AWS EC2 instances other than SSH. This option is great for those instances that need to have a public IP attached or need to be placed in a public-facing subnet for one reason or another.

Also, the Systems Manager may not be all that well known, but it might be depending on how you are using AWS. Lastly, there are pre-requisites to getting this working, but bounce around this video, it's for you anyway! :)

Bash Hell

I just picked up an MR review from a team member and it's a multi-file bash script, over 1500 lines. I'm just curious what other opinions are in using bash to this extent?

I personally would try to keep a bash or PoSH script under 100-150 lines and if I got into a situation like the submitter I would use a more equipped programming language, but I'm also not a senior dev and don't have enough experience to really have a good reason on why not to use bash like this. It just feels wrong if that makes sense.

Feedback wanted! Koncrete: Cloud-hosted CD for Kubernetes

Hey Devops reddit! We are David, Scott, and Tian - we've been working on a cloud-hosted CD service for k8s called Koncrete that we would love some feedback on.

# What is this thing?

Koncrete is cloud-hosted continuous delivery for Kubernetes, powered by ArgoCD. It's a super quick and simple way to get started with Gitops. In minutes you get ArgoCD with a few handy integrations pre-configured - like Authentication, Github webhooks, and Slack notifications. You can test it out for free here, it should really only take a couple of minutes to setup.

While setting up Argo itself is not particularly difficult, configuring integrations and hosting can be a distraction for those getting started with Gitops. Getting started with Koncrete is as easy as connecting a gitops ready repo (or our example repo) and a Kubernetes cluster*.*

# Background

We are the team behind Kalm, an open source k8s toolset we built during the W21 YC batch. While building Kalm, we had the experience of learning GitOps for the first time, and thought it was weird that the bulk of the tutorials we found were all about "How to Install Flux/Argo", and very little about GitOps best practices. We joked that it was as if we were searching for "How to Write Better Blogs" and all we were getting back were "How to Self-Host Wordpress" results.

So we decided to create a one click GitOps service for people want to focus more on setting up well crafted GitOps projects, and less on configuring and maintaining GitOps operators.

We're leveraging a lot of great open source projects (like ArgoCD) to make this happen. We plan to open source core libraries along the way.

# How to try it!

We're looking for help! We really need feedback from Kubernetes enthusiasts! Specifically:

Run through our [getting started demo](https://docs.koncrete.dev/Getting-Started-0e835a43c944493ea5a591dea5dc804d) (free). Any and all feedback would be amazing.
If you have experience with GitOps - do you think something like this is useful? Why / why not?

We offer a free tier that is sufficient for hobbyist projects and small production clusters, so there's no cost to test :)

Thanks all!

YAML in vscode not being validated with YAML extension

So I'm trying to setup YAML validation in VSCode for a myriad of YAML files my team is working with. I'm a little hung up on what is supposed to be done to set it up on windows. I installed the YAML extension and put in the \`settings.json\` where my yaml schema and files are located, i.e.:

"yaml.schemas": {
".\\path\\to\\schema.yaml": "*.yaml",
}

But when I go to my yaml files, no validation is happening. No redlines or nothing. Is there something else I need to do? The stuff I've looked at on the interwebs for help have been less than helpful...
