Help with Linux server

I’m new to server setup and maintenance and am stumped trying to setup my Linux server for a personal project.

I’ve got a completely fresh install of Linux - only things I’ve done so far is setup SSH access, install nodeJS and npm and clone my GitHub repo.

I set my server running and saw the console log I’d set up to indicate it’s running fine on port 5000. However when I try to access it from google chrome or Postman, I get ERR_CONNECTION_TIMED_OUT and no console log from my application, which is set to console log a message whenever it’s hit.

I’ve tried setting up a simple HTTP server using Python and that’s not working either.

I’m sure I’ve missed something super basic so if someone could point me in the right direction I’d much appreciate it.

great o'reilly ebook deal on humble bundle

I've had many people recommend some of these books to me over the years, but it can obviously be expensive to try to build a library of them. Anyway, I don't even know how I ended up stumbling into this today, but I thought I'd share it. Considering that 90% of people in this sub are asking for advice on what to learn, I am certain that there is 25 dollars worth of value in here for most of you.

Observability - The eBPF Effect

I recently published the first of a two part feature on the impact of eBPF on observability tooling. The first part looked at eBPF in general, this part looks at how vendors such as Groundcover, Odigos, Beyla and others are using ePBF in their products as well as some of the challenges and limitations they face:

If you are using any of these in prod, it would be really interesting to hear about it.

Version and project management tools

Hi,

I just got hired as a developer for a small team of 10 people with a possibility to hire 5 more. Group has no concept of version management system. On their network folders they have filename_bkp.* and filename.*

They use One note to write down projects we are working on. We are a Microsoft shop currently.

My previous job was with a 5000+ employees with a huge devops team. We used github and JIRA but I never configured any of them.

Now, I have been tasked to find version management and project management tools. Can you all suggest some tools?

thank you.

Correct stack for my growing project

Hi there. I just built a store. The frontend is in Vercel, the backend code is in render, images are stored in cloudinary and database in supabase. My project is growing, is this approach still suitable or do I need to consider moving to a service like AWS or something?
Any advice will be welcome

How can one do data(base) migrations or conversions?

How often do you release and how are your code changes reflected in database structure (schema)?

Let's say feature1 branch merge in some-source-code-repo.git needs to go out toghether with feature1-data branch merge in another-but-database-sql-code-repo.git - how do you make it happen in non-cloud and cloud?

What are my options? We do mix of liquibase/Python/Bash scripts against Psql and MySQL, there's some ansible scripting to setup a Redis (Valkey) reference structure, I'd maybe like to have one leash to do all this fragmented stuff with?

I'm curious what you guys use to manage your deployments into a cluster

I am using argocd and a GitHub action to build the container then use argocd-image-upater, it doesn't work great when taging containers as latest.

Curious how you guys manage this kind of deployed

Moving from SysAdmin to DevOps team at my company

Hey everyone,

I’ve been working as a sysadmin at a bank for a little over 2.5 years. My team manages the IT infrastructure. Throughout my time here I’ve been fortunate to develop great relationships with not only the manager of the DevOps team, but the team as a whole. That’s led to me owning the majority of the work the DevOps team needs from mine. I’ve even done a few projects for them, some being in quite a grey area of responsibility, as they were moreso DevOps projects but the team gave me them to help support my career growth (and to have another hand in supporting their efforts).

Let’s call my current manager (SysAdmin director) Jordan and the DevOps manager Marcus.


Marcus and I, especially, have had great rapport for a while. We have similar interests (weightlifting) and have always vibed. Over a year ago he joked about me joining his team at some point.

Now that’s finally happening.

We had a catchup where I directly told him I would love to join his team. He echoed the same sentiment and told me he would like me to be his “lieutenant”. Essentially his 2nd in command. He also shared that he hired someone externally (who I know well) about 6 months ago with the idea that he would fill that role, but unfortunately found that he’s lacking some of the qualities to fill it. Leadership and presence, primarily. Which I understand, as while I genuinely like this person, he is a bit sloppy and I can see him representing the team being an issue.

We’ll be talking specifics about this transition in about a month when he returns from travel. A few questions I have for you more experienced folks on how to approach this…


1. What salary should I target? I expect (and would like) my title to be DevOps engineer. My current title is systems administrator. I make 80k base + 15% bonus. The bonus applies to all employees and is based on company performance, not individual performance. Would it be unreasonable for me to target 100-110k base? I have only 5.5 years of total IT experience and no bachelors degree, which gives me some pause in negotiating.

2. Any tips on navigating this political situation? I’m aiming to minimize damage to my relationship with Jordan, as well as to the relationship between Jordan and Marcus. This is one of Marcus’s primary concerns in the transition, as our teams work closely together.

I really appreciate any guidance here. Thank you!!

live coding interview - confused

So I just had the second round of interviews in the hiring process and it was really not what I was expecting… I was prepared to write something related to automation, pipelines, IaC but the first question was to write some code that I would expect that a SWE wouldn’t have trouble to come up with a solution. I ran out of time, and moved to the next problem which was a follow-up on the first. I tried really hard to write something and even tried to explain my approach to the problem, but no working code came out at the time. I let the interviewer know that this isn’t something that would be part of the day of a DevOps person and he even agreed but 🤷🏻‍♂️ I’m super sad now because I was really looking forward to work with these folks and I left the call with the feeling that I did horribly bad. That’s it, sorry. I just needed to vent :(

Feeling guilty and useless

A junior being given more and more responsibilities. I don’t usually respond back to pings immediately unless I’m sure of the answer. But it’s all blurring and trying to figure out when I should be taking vacation,how many days (week or two) , and how much is too much.

I have 3/4 certs which I want to get to hit milestones but I am also expecting a baby boy soon in 6 months. How to keep work and life separate?

What are you guys doing to stay on top of things, learning new things without feeling like a dumbass. At what point do you ask for help - currently stuck on something new to me but I’m sure trivial for others. Damn this feeling sucks lol, just looking for advice is it really - how the hell do you manage

How do you measure team performance?

I was at a Platform Engineers meetup and a couple were saying that DORA metrics aren't an accurate way to measure team performance. Okay so I know what not to do, but how do you measure team performance?

What are industry standards on RabbitMQ queues and routing keys?

Hey everyone,

I'm trying to implement a rabbitMQ where I have several different publishers, and several consumers
I am using it as an event bus, so multiple applications are using the same RabbitMQ.

What are industry standards regarding routing keys and queues? I currently have multiple bindings on some queues, which I reuse in my consumer code.
Basically, queue A has 3 bindings 1, 2 and 3. In the consumer code, i listen to the queue, and according to the routing key, I execute one method or another. That sounds weird no?
The problem is that I can't use the shovel plugin to redrive from the DLQ to the main queue (because I lose the routing key, so I don't know which method should execute on consumer side).

How are you guys doing? Are you using one routing key per queue? If so, what's the purpose of routing keys?
Thanks!

One reason why I love Ansible over Puppet over Chef (Salt is somwhere between the latter two)

I need to recreate a lot of environments on regular basis as I am responsible for enabling our SEs and PS staff in terms of devops. As customers could use anything really I try to give them at least the basics of it all.

Anyway, my workflow is MacBook with local Ansible instance > deploy whatever is needed in either AWS or Azure using bash or ansible or mix thereof.

So I automated the deployment (with various client tools like Apache, Certificates and our own agents) so it can be reproduced in a few minutes.

So I just completed automating Ansible, Puppet and Chef with .. well Ansible.

How many lines of code you wonder (if not I tell you anyway)

Chef : 650 lines of Ansible Playbook
Puppet : 220 lines of Ansible Playbook
Ansible : 150 lines of Ansible Playbook


Does not include any AWS / Azure / Bash specific code.

Hate Chef .... Love Ansible ... the contrast is so crazy really (especially in terms of simplicity).

(kubernetes) Are helm release generated certificates less secure than the ones created by cert manager?

Hi,

to illustrate what I mean let's take mongodb-bitnami chart [https://github.com/bitnami/charts/blob/main/bitnami/mongodb/values.yaml](https://github.com/bitnami/charts/blob/main/bitnami/mongodb/values.yaml) `tls:` section is of interest to me.

I want to enable mutual tls between the client and the server(both are in the same kubernetes cluser). I have 2 options on how to do this:

1. Leave `autoGenerated` on `on`

2. Disable auto generation and instead prvide name of the secret generated with cert-manager

sually I'd go with solution 2, but as you can see in the values this chart requires very specific keys inside the secret `\`mongodb-ca-cert\`, \`mongodb-ca-key'`, unfortunately, cert-manager does not provide option to generate secret with non-standard key names. Making some kind of job would be a pain in the ass, seeing how certificates are replaced after a while.
So the question is, is it safe to simply use certs generated by mongo? My first problem is that it seems they never expire, it's just the same certificate forever. Another concert is that it's just fishy to generated ca and cert at the same time and then make client trust it. At this point is that cert even giving me anything?

If anyone has some words of wisdom I'd be grateful if you shared.

Do you know any big DevOps projects?

I'm a beginner and I want to learn by looking through the code of others more experienced than me to see how they approach things. Looking for something that combines kubernetes, cloud and CI/CD (basically lots of devops tools). Found a few projects on GitHub, but they're all too simple (nothing complex or advances, just scratching the surface).
Do you know or have any big devops projects that I can take a look at?

Help Needed: Enabling Streaming Responses for AWS Lambda Chatbot built with Flask


Hello everyone,

I’ve been working on developing a chatbot using Flask, and I’m now looking to enable streaming responses. Despite following multiple posts and guides, I haven’t been able to get it to work effectively. I’m considering using AWS Lambda and API Gateway to establish the streaming response functionality.

Has anyone successfully implemented streaming responses in a similar setup? Could you share any resources or guidance on how to achieve this?

Here’s a bit more about my setup:
- Framework: Flask
- Infrastructure: AWS (considering Lambda and API Gateway)

Any step-by-step guides, code snippets, or pointers to useful tutorials would be greatly appreciated!

Thank you!
