Frequent Targetgroupbinding reconciliation on an EKS Cluster

Hi Everyone,

Viewing my event logs, my EKS cluster tends to perform a lot of reconciling (less than 15mins continuously) by Targetgroupbinding with exposed service containers.

I understand it has to perform leader board election but checking if this is normal behavior

What to expect for first DevOps interview? (with DoD-based contractor)

Hi everyone, while I think I have a federal "DevOps" role in the bag (seems to be taking forever for a solid offer letter though). I was invited by two DoD based companies to do an interview with them for mid-DevOps roles. I'm DevOps now, I think?

I use docker, Ansible, I create bash or python scripts to lockdown systems or to install sw prereqs, I do site reliability (but without monitoring software), I troubleshoot finicky service scripts, I ACAS scan systems for security vulnerabilities, I create and backup Linux systems, and of course more. So I do DevOps stuff but then I look at these job listings I applied for and I don't know cloud (@lat least no work experience), I don't know load balancers, I haven't produced code for a project, I don't know kubernetes, I don't practice leetCodes. Am I walking into a mind field for this interview? I have "PowerShell" scripting on my resume but now that I think of it, I have scripted anything in PowerShell since I made my few "Windows baseline configuration" scripts 2-3 years ago. 😶 I just use them quite often.

DevOps broadness is awesome when you're on the jobs but nerve-racking when you are trying to land a position. My current position was for Systems Administration but I kind of got thrown onto a very fast moving agile development project where I learned my above skills.

So what is expected of me if I don't know some of these technologies, what are some ways you guys navigate unknown technology questions in interviews?

Monitoring mobile apps

How do you monitor your mobile apps to see if it has issues loading?
Story: We have mobile apps available from both Playstore and App store. We get issues sometimes when the app doesn't load at all or shows a blank page. Web application(browser based) loads fine at all times. Hence all our monitoring checks pass as it's looking at web applications only.

My question is how do you ensure uptime on mobile apps? Please advise.

Folks In Healthcare Industries, what do you use for application monitoring?

Tl;dr: Large hospital, primarily Windows Desktop/Server, Epic. We have infrastructure monitoring covered, what do you recommend for application monitoring when there is TONS of health care applications already in the environment?

Without disclosing much, I work a hospital. Rather large one. We're an Epic shop. We run our own datacenter. Been here for 4 years, came onto the DevOps team recently. Started in operations, went over to the systems administration team so it's a huge plus as a lot of the monitoring tools I used to be the operator on, I am now the maintainer.

I had a realization today that we don't have a clear tool to do application monitoring. Infrastructure is certainly covered as we have vROps, Loginsight, NagiosXI and other solutions at our disposal to monitor the underlying infrastructure. I've tried working with Telegraf, which is integrated with vROps now; had my gripes and such with it but it does OK; just not the best or what I would want for my org for an application monitoring perspective. Best we can do right now is Windows Services monitoring, but I know we can do better than that.

There must be at least 200+ applications in the environment total. That's just a guess. I checked out roadmap.sh and it mentions Jaeger, New Relic, App Dynamics, Instana, OpenTelemtry. Checked out Dynatrace but the agent is 5gigabytes.... just seems a bit big.

What's your take?


Edit: I have a test environment at work that is usable. Additionally, my own homelab at home. So I'm ready to tear at something. Just wanted to gear it towards Healthcare applications specifically.

This is my nginx.conf:

}

}

Error from error.log:

My 2023 plan

I'm a noob to devops, but not a noob to software development. Anyway, my current job is titled as devops but it's actually code fixes and maintenance and shit, hardly an opportunity to learn cool new shit, particularly cloud native stuff, which I'm interested in. I've made a plan to learn cloud native stuff in my free time. Here's the plan below and let me know what you think:

Goal: deploy and manage full stack app in k8s

\- pick a cloud from either Azure, AWS, GCP

\- learn ArgoCD

\- learn Rancher

\- try out GitLab CI/CD

Thoughts on using GPT tools with databases

Team members have discussed the implementation of an AI product for querying databases. While I have some initial reservations, I am also intrigued by the product's innovative features. I understand that it may appeal to small/medium companies with limited resources, but I am interested in exploring its potential and determining if it offers any advantages over developing a solution using open-source tools.

I would welcome any insights or perspectives from those who have knowledge or experience with similar tools.

CVE vs CWE

Hi all, so my company is moving from Veracode to Mend(White source) for code scanning - I’m trying to do a small test to check if mend is able to catch all the vulnerabilities caught by veracode for the same library. I noticed that mend wasn’t able to catch some vulnerabilities that veracode could figure out. We also use codeQL for CWE scans and I don’t have that data yet with me- but I wanted to know how much of a difference will it make if I do get the CWE data for the same library- will it be able to make up for the discrepancy as CWEs are different from CVEs. I really need some help here! Thanks a lot in advance!

Azure DNS query logs for analysis

Hello Everyone,


I am working on a project where I have to do analysis of the DNS Queries (A record,AAAA record,CNAME record) on Azure Platform to make cloud infrastructure related decisions.


I have checked the metrics option in the Azure Portal that seems to be with limited with the scope i.e. query volume of A records.

I am looking for solution with more insights on the DNS Queries, can this be achieved using any Azure Services or any kind of scripting.


Thanks in Advance

Pearson VUE cancelled and refunded my 'AWS Professional devops engineer' cert test with no reason.

Anyone else have this issue? I signed up and payed earlier in January. Course showed as active upcoming. Today I received email stating my cert test time/date has been cancelled and refunded with no other reasoning. Is this normal? How can I guarantee this won't happen again or closer to the exam date?

Update: I contacted PEarsonVue customer support and they had no answers. They told me to apply again

Dockerized Jfrog Platform

Hi friends,

My team and I are looking to install the Jfrog platform (Artifactory, Xray) but we’re hesitant if we should run these services as docker containers. Especially the Postgres DB for each service. We are a supporting around 100 developers.

Update: it will be self-hosted.

Best way to draw attention of knowledge acquired through home labs

I want to get into a Dev-Ops job in the future, the issue I am facing is that all my previous work experience and training have been in the Electrical/Project Management field. Most of my knowledge of Dev-ops comes from running my home servers, setting things up as I need them, or seeing things that others have done that look interesting.

I am going to update my GitHub with a project to provision a Kubernetes cluster on my local Proxmox server using Terraform and Ansible, so I will at least have something for others to potentially look at. I know it is not terribly inventive, but it does show that I can at least use those technologies, along with Git.

My question is how can I show that I have this knowledge to potential job employers? I can easily pass the A+ certificate, but, I think that will lead to more of a help-desk role. I can do a help-desk role, but that seems like it leads more to a sys-admin role than a dev-ops role. If I study a bit, I can pass the CKA certificate, but after looking last night at job offers, it doesn't seem that many people are specifically looking for that certificate. Any suggestions?

I would like some constructive criticism on my resume

I recently found an entry level position in my area at a decent company and figured now would be a good time to plant myself in one company for a few years.

That said, I want to put my best foot forward as far as the resume is concerned. I'm using the resume that got me my most recent position, but I'm not sure how well it communicates my experiences or skills.

I'm open to plenty of changes, so don't be afraid to be direct. Thanks for taking the time to help!

Fig Scripts: Build internal CLI tools really fast

Hey everyone! I'm Brendan, founder of Fig. Fig makes the shell easier and more collaborative.

We recently started working on Fig Scripts, a ridiculously easy way to build and share internal CLI tools. I've included more info below. You can try it out here or watch this quick demo video.

Our ask

Our team would love to hear any feedback from people in the field on what we’ve built. Where would you use this? What would you use instead? It’s still early, there are kinks, but we really would love to hear your thoughts (positive or negative)! 😊

\------------------

Why did we build this?

There is surprisingly a lot of friction involved in building an internal CLI. Instead of writing business logic, a lot of your time is spent on boilerplate: integrating with the CLI framework, reading/validating user input, working out how to distribute/update your tool, tracking usage and errors, even adding colored output... This is stupid. You should be spending your time writing your business logic, not doing boilerplate!

How does Fig Scripts work?

We’ve built a platform to build, distribute, and manage your internal scripts and CLI tools. We handle all the boilerplate, you focus on writing your business logic.

Some key features are:

Jupyter-notebook style interface with multi-language support (bash, python, js/ts...)
Easy input definition: Fig's out-of-the-box terminal UI library makes accepting user input easy. We even generate the CLI flags for you.
Instant cross-device sync: Changes are instantly provisioned to everyone on your team.
Built-in usage monitoring and error reporting: See how frequently scripts/subcommands are used and what the most common errors are.

Coming soon, we are going to add integrations with popular developer infrastructure (like AWS, Docker, GitHub), cron jobs, new cell types (like markdown), more language support, and the ability to run scripts in the cloud.

Helm-Dashboard is generally available with the release of V.1.0.0

Komodor’s latest open-source project, [Helm-Dashboard](https://github.com/komodorio/helm-dashboard) is generally available with the release of V.1.0.0

Coincidently at the same time the project crossed 3K stars on GitHub (and hundreds of daily active users), only three months since it was released!

Some of the cool new features you can expect to see in the new version:

* Auto-update repositories when installed into cluster
* The ability to reconfigure charts without access to their source
* Specifying multiple working namespaces
* Self-sufficient binary, no helm/kubectl requirement
* REST API documented

As always, we welcome everyone to provide feedback and suggestions on the project’s roadmap on our social channels, [GitHub](https://github.com/komodorio/helm-dashboard), or the [Slack Kommunity](https://join.slack.com/t/komodorkommunity/shared_invite/zt-1lz4cme86-2zIKTRtTFnzL_UNxaUS9yw). We’ve even created a [user survey form](https://docs.google.com/forms/d/e/1FAIpQLScwuJf-LmpA2zk_fVaCh2eStZn5IjP0yGPWQ785wPEvDJLP7A/viewform) to make it easier on you 🙂

Custom systemd service for NodeApp on uBuntu fails to connect to local MongoDB instance.

So I have a two tiered application running on separate instances on AWS, an API and Mongo.

The API (node app) instance provisions with a custom service to start the node app with forever as the uBuntu user.

When this happens I am unable to get responses from Mongo, but if I stop the service and start the app manually with node or forever it works.

So this seems like a service issue and perhaps permissions to establish a connection to Mongo db?

Any pointers on where to look for possible cause ?

Edit: Solved by adding any environment variables to the .service file.
