Launch.json config for listening to a containerized app not working

I have a straightforward setup and I see Debugger listening on ws://127.0.0.1:5555, but when I try to listen to the debugger port, VS Code hangs and doesn't output any error message. Why would it work on Linux, but not on Windows, and what are the fixes?

{

"version": "0.2.0",

"configurations": [

{

"type": "node",

"request": "attach",

"name": "Attach to Docker Container",

"address": "localhost",

"port": 5555,

"localRoot": "${workspaceFolder}",

"remoteRoot": "/usr/src/app"

}

]

}




It looks something like this, and I was wondering what I can do to debug and find out why it's not working. I am using ts-node-dev.

Exploring the 12-Factor App Methodology: A Blueprint for Building Scalable and Resilient Cloud-Native Applications

Hey everyone,

I wanted to share a comprehensive blog post I just published about the **12-Factor App methodology**—a set of best practices designed to help developers build scalable, maintainable, and resilient cloud-native applications.

If you're working with **DevOps**, **microservices**, or building applications that need to thrive in **cloud environments**, understanding and applying these 12 factors can be a game-changer. In the post, I dive deep into each principle, explaining how they contribute to building modern, robust applications. I've also included book recommendations for each factor to help you explore these concepts further.

**What you’ll find in the blog:**

* An overview of all 12 factors, from codebase management to treating logs as event streams
* Practical insights on how to implement these principles in your projects
* Book recommendations to deepen your understanding of each factor

If you're interested in improving your application development practices, I think you'll find this post valuable.

🔗 \[[Check out the blog here](https://medium.com/@srivatssan/the-12-factor-app-methodology-a-blueprint-for-modern-cloud-native-applications-c1aea2984bde?sk=e2e214a30f30be4dfe7495b5fc27c80a)\]

I'd love to hear your thoughts and any experiences you've had implementing the 12-Factor App principles in your work!

Advice about Staff Role

I recently got promoted to Staff Engineer and I'm trying to find my footing. I've been leading Observability at my company for a few years. I've done trainings, worked on tooling improvements and we've now aligned my ideas with our business goals, and I'm working on a proper roadmap. I'm confused about the shape of my role based on my interests.

I like the intersection of SRE/DevOps/Platform and how teams are using tooling. As an example, I'm not stimulated by the idea of migrating our company off DataDog to OpenTelemetry so we can use other vendors. I'm much more excited about working with teams to leverage OpenTelemetry and other abstractions in ways that make our system much easier to debug. As a concrete example, I worked on an approach where we collect a lot more telemetry and automatically attach it to spans/traces in DataDog. Possibly I could get excited about it.. but not sure yet. I'm also passionate about education, so I love doing presentations and sourcing folks to increase engineer competency with our tools. I'm also pretty passionate about architecture and love building things. I also love to feel the pain of the Observability tool and would love to continue building apps that utilize them.

What does that make me? I've gotten a couple of suggestions:

Office of the CTO - detach myself from a team and report directly into the CTO
Staff Platform Engineer - become a Staff Engineer on the Platform side. I'm not sure what the usual expectation is with this though. I'm not a fan of going all the way and writing TerraForm and such for the rest of my days.
Staff Observability Engineer - I've seen a couple posts like this but these all seem to require deep knowledge of Prometheus and other tools in that space, which feels more SRE/DevOpsy to me.
Staff Engineer within a team - this is my current state, which I dislike because it doesn't give me enough time to focus on Observability.

I'd love to get some feedback from others who have navigated this journey, made strides, have thoughts, ideas, anything! Thanks in advance!

Is writing CI(/CD) tool agnostic pipelines the way to go in 2024?

Wouldn't it make most sense to create pipelines that only call scripts that you could run on any system or container, independent of what tools you use?

How do you guys do it?



Right now we're using Jenkins for CI.

Yep, just because we're stuck using Bitbucket.

To make pipeline creation easier, we're putting every little shit into Jenkins Libraries to call an insane amount of Groovy functions to "simplify" pipeline creation and management.
1. Main Pipeline calls the library function that contains the actual pipeline with its stages (in the worst case we're adding 50+ line long map full of parameters to the function call - with stuff like 'what stages to run', 'what registry to push to', etc.).
2. For every stage, the pipeline calls new functions for each task, using the map from the function call at the beginning for their settings.
3. These task functions now call Jenkins pipeline steps (the actual stuff that does things, like Shell, Maven, Docker Builds, etc.) - yet these goddamn task functions are Jenkins pipeline steps themselves too.

We did it, because:
a) - changing 200 Jenkinsfiles distributet between 70 repos became a pain in the ass to manage. Much fun having to change ONE function in any of them.
b) - our devs should be able to use and create pipelines without our input.
c) - to streamline the setup and structure of our repos.

It's not as bad as it seems. Mostly since I actually document that stuff.
But the size it's reached is immense and we're slowly drifting into a "there's no way out" situation with Jenkins.

Working on this feels somewhat wrong now.

Salaries in the Netherlands

Hey fellow engineers, I have been looking into salaries range for devops engineer position in the Netherlands and found they are from 43.400 EUR and 71.100 EUR per year. I would like to see whether it is accurate from your experience.

I have been working as a contractor for the small Dutch firm for some time and lately I have been thinking about moving to the country, but I am not sure, for instance, that 43.400 EUR is a competitive salary for our specialty and if it is going to cover the costs, to be honest. Also, not sure if that’s gross or net amount.

So, basically, I would like to hear from your side what is an actual average salary and how competitive is the market now if, for instance, my employer would not be able to match the average or close-to-average.

Do you link feature flags with observability? Could that be valuable?

In this demo, I have cobbled together an early PoC on how you can use OpenFeature (an open standard for feature flagging) and OpenTelemetry to tie feature flagging and observability in a vendor agnostic way.

I have taken a simple example of changing LLM models underneath using feature flags and getting tracing and logs data from the application in SigNoz.

It is a early demo as of now, but would love ideas on what would be interesting use cases for you to see here? Is this something which would be useful for you?

Using Docker Containers vs Installing Software / Tools on Bare Metal

So, A stupid question but I have to ask. I am doing some projects / home labs so that I can add them into my resume since I have no professional experience.
I want to know if it is better to use docker container or is it frowned upon by interviewers because it is easy compared to installing on bare metal and configuring it.

Like let's say, I want to deploy Grafana and use Prometheus and Loki as a data source. I can easily spin up the containers for Grafana and Prometheus do my lab, post it on LinkedIn and be done with it.

Is it the right / production way to do things? I mean I know what the tools is for and know how to use it or maybe I am just overthinking it (?).

Managing expectations without managing expectations?

Essentially, being green on a team of 3 (including 2 other devops engineers) - they both interviewed me and know my skill learn and where I align, plus their job posting was looking for a junior devops engineer. The two other engineers are brilliant, Principal level engineers. Since i joined, (1+yr ago) - I have had a bit role on the team, and now it’s progressing a lot more. Taking over established processes for application deployments, troubleshooting for pipelines, the developer teams which we support are inquiring or reaching out via our MS teams channel and or tickets. I am also being assigned more work, with less detailed ways of completing the tasks - which is Great! Not complaining about this at all, as I think this will help me figure things out and learn more.

Now the developers we support, I dont know if they realize my skill level or lack there of, / devops internal level. Everyone I work with and help support has seemingly 8+yrs professionally and they are able to complete multiple tasks (whether devops or developer) in a matter of a day or week.

With these new assignments and less detailed ways of completing things, It is taking me a little longer than I would like. Since it is also a lot of troubleshooting, and making sure I am using the tech - which 9 times out of 10 - I have never used before, so that adds to the time. So what should maybe take a day for example took me 3 working days if i am being honest. I have further things coming down the pipeline - requests from the development teams - which I realize may take a slight delay as well.

Is there a way to help manage those expectations? I am learning, I admit I’m not as proficient or effective as my colleagues, but its embarrassing having to say I’m not progressing or stuck on XYZ for 2 days, when I’m sure in the heads of the development team it was a simple ask/task. I also dont want to be dependent on my colleagues as well.

Seeking feedback, maybe a better way to handle a situation like this - I know i need to improve and the learning is endless, and definitely feeds like a ways to go before I feel “caught up”

DNS registrar-level outage: a thought experiment

I'm designing some backup components for our infrastructure and have exported the zone records for my primary domain, mydomain .com to BIND format and saved the files to a remote bucket. But it occurred to me: mydomain .com's registration is hosted by our cloud provider. If our cloud provider account were in some way compromised, or if the project that housed the zone files were deleted, our DNS would be toast.

Even if the zone files were removed but the project was fine, we wouldn't be able to log in to the cloud provider to restore the zone files, because we use SSO using our mydomain .com domain.

Looking at the WHOIS contact information for mydomain .com, all of the contacts are someaddress@mydomain .com - which means that they would be offline in the event of a DNS emergency. So even communicating with the registrar would be difficult and add quite a bit of time to our RTO.

Have you ever war-gamed this scenario before? Was there a risk mitigation you came up with that was satisfying?
