Preferred Dev/Deploy stack for basic python database app?

Retired devops guy here, almost a decade out of date. To update my skillset, I’d like to write a web/database app for a non-profit org I volunteer for.
My favored language is python. I’d like to do all-the-things as code, including provisioning, deployment, and database structure. I’d like to host it in the cloud, preferably free/cheap tier (it won’t get much traffic).
I’m starting the research phase, and thought y’all could help me focus in on what might be appropriate to look at.

Ever Struggled with SSL/TLS Certificate Chains? Check This Out!

Hey everyone 👋,

I've just published a simple guide on SSL/TLS certificate chains on GitHub. This is my own notes I have kept in for a long time and I thought I shared to everyone and I'm curious to know what you think? I made it very simple enough to understand, breaking down what certificate chains are, how they work, and gave a real world example.

If you find it useful, please star or watch my repo. If not, any feedback to make it better and simple?

Check it out and let me know: GitHub - Understanding Certificate Chains: A Simple Guide

Thanks in advance!

Eraser AI

I found a useful tool today after I sifted through a post here from several months ago via my technical diagram query. I’ve worked in the Fortune 100 space for the last several years and diagramming tools have not been easy or fun. I don’t think the AI feature of Eraser was out several months ago when this product was discussed, but I think it deserves another discussion.

For those with other AI-powered technical visual/design tool experience, does Eraser AI detail a complex architecture better than the others, LucidCharts beta AI for example
? I tried diagramming with ChatGPT 3.5 in the beginning and wasn’t impressed. But models have clearly improved since then, and watching Eraser AI diagram my two year project in less than a minute with < 200 words was satisfying.

I need 1000 concurrent iOS builds via Jenkins

We have a special requirement where we'll need 1000+ builds. All building concurrently.

Now, our main CI is Jenkins hosted in GCP.

What would be the best way to have this running?

1. AWS - Not very straightforward. But is it possible via ASG?

2. MacStadium - Seems the best option here since it's plugin has dynamic provisioning.

3. Anything else?

What does everyone think of this recommended path I shared below?

https://raw.githubusercontent.com/milanm/DevOps-Roadmap/master/DevOps%20Roadmap.png

I found this roadmap today and wanted to hear some opinions about it. I have some fair knowledge about Git, JS development, Linux, and networking.

If I can dedicate at least 2 hours a day for this journey if not more, how long should I take on average to learn more about each topic? Of course there won't be an accurate figure. But from everyone's experience, on average, how long does it usually take? And how many projects should I involve myself with?

Installing sentry on kubernetes

Hello, I have been struggling with installing Sentry on Kubernetes.

The challenge is I have not found any good helm chart. These ones I found do not appear to install sentry, and I am not clear as to the purpose of the charts.

Managing Ephemeral Storage in EKS with Bottlerocket Nodes

Hi everyone,

I have a question about ephemeral storage in EKS. I'm using version 1.29 and Bottlerocket images for the nodes. I deployed the cluster with Terraform. I noticed that the nodes have two volumes: a 2GB volume for the OS and a 20GB volume for data, which is the ephemeral volume.
Sometimes I encounter disk pressure issues, causing pods to be evicted. Before increasing the 20GB volume, which I understand is the default value, I want to understand how EKS manages this volume. Specifically, does EKS always maintain the volume at 80% usage? It seems to consistently hover around that capacity, leaving little room to handle these disk pressure incidents. I want to ensure that if I increase the volume to 40GB, it won't always remain at 80% usage.

Can anyone provide insights or share their experiences with managing ephemeral storage in EKS?Thanks!

Peer Code Review Tool

Hi,
We’re currently using GitLab with Atlassian Crucible for our peer code reviewing. GitLab doesn’t look like they’ll ever support a single code review for multiple projects.
Crucible is now in ‘basic maintenance’ mode therefore we’d ideally want to move to an alternative tool which is actively maintained.

Is there anything out there that does this as a standalone product or is the solution to find a tool like BitBucket which handles the repositories and the code reviewing?

Thanks

What do you use at your org? Azure DevOps or GitHub Team?

I am working with a team of devs and we have been using GitHub teams for some time. In the beginning it was pretty good. But now it is not enough anymore.

The team is not happy with the project management tools provided by GitHub.
Resources for GitHub actions are not enough, we are exclusively using self-hosted runners.
We are worried about GitHub packages and the storage limit set for it.
Basically we are paying 4 USD per user just for version controlling.

To all the devs working in organizations, what has your experience been like? Would you prefer working with Azure DevOps instead?

Oh and if it helps, we use Azure for all our resource requirements.

Thanks for your time!

Platform as a Product 101

So, we wrote up an intro/overview of what the platform as a product strategy looks like in practice since that concept has taken off in the past few months. But is anyone on here actually utilizing PaaP in their own organization that's not one of the big tech companies? Any examples you can share of how you're utilizing it in your own org?

Or is it all cap/irrelevant? Would love thoughts from both individual devs and those who maybe are in charge of leading full dev teams. :)

Check it out, thanks!

Elastic search question

Hi 👋 I am not a developer (or anything technical). I am a bootstrap founder looking for solutions for e-commerce and retail in my vertical using tech.

I discovered Elastic today. I uploaded a csv of products (skus) to test and can query the index with their example console to search for, as an example, a product with “cane sugar” in the ingredients. I’d like to know:

1) what code do I put in the php console to ask the index to show products that “do not contain cane sugar” for example (sort of an “if then” query)
2) how do I make a query that reads the ingredients or attributes in a product and then spits out (matches it to) their description (stored in the csv)? As in if a customer wanted to scan a product to read the ingredients attributes?
3) (I’m a total rookie I know) but how do I “export” what I’ve built and make it look pretty on the front end for customers to use on our website (integrate it) or app?

I know I’m totally out of my league here and feel quite dumb but this has been bothering me and I know there’s a simple solution, I just don’t have the skill yet would like to try. Also, if you don’t ask you’ll never know.

Terraform does not respect `depends_on`?

Hey Terraform gurus.

It seems that `depends_on` does not affect order in which Terraform creates resources. A minimal example:

resource "null_resource" "foo" {
provisioner "local-exec" {
command = "./foo"
}
}

resource "null_resource" "bar" {
depends_on = [null_resource.foo]
provisioner "local-exec" {
command = "./bar"
}
}

Output of `terraform plan`:

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
+ create

Terraform will perform the following actions:

# null_resource.bar will be created
+ resource "null_resource" "bar" {
+ id = (known after apply)
}

# null_resource.foo will be created
+ resource "null_resource" "foo" {
+ id = (known after apply)
}

Plan: 2 to add, 0 to change, 0 to destroy.

Why is `bar` goes before `foo`? Am I missing something?


Update: when I do `apply`, order is correct. So, I can't trust `plan`?

My version:

Terraform v1.8.3
on linux_386
+ provider registry.terraform.io/hashicorp/null v3.2.2

How are elevateduser and elevatedpassword used in a Packer template?

I had assumed that the user defined in the Packer `winrm_username` setting was logging in as an admin and could perform tasks as such. It seems there is some nuance to that. One of the things that it fails to do is run `Enable-WindowsOptionalFeature` in a Powershell provisioner with "Access is denied".

I'm concluding that the error is because the user isn't actually logged in as an admin and therefore must invoke a new Powershell environment with elevated privileges. This means using the `elevated_username` and `elevated_password` settings.

The Packer documentation doesn't often make it clear how to use a setting. For the `elevated_` settings, my guess is that I can use the automatically generated password used by the `winrm_username` user. I'm using HCL2 so this is `${build.Password}`. Does this mean `elevated_username` would be the same as `winrm_username` or would I use Administrator with it having the same password?

Do I need to do anything to inform Packer that a command should be executed in an elevated environment or does it automatically do that when it sees that the `elevated_` settings are configured?

Programming and the military.

So I’ve been thinking about how military ideas could work in software development, especially the commander's intent concept. And slowly incorporating it into my startup.

This concept sets clear goals, letting teams be flexible in how they achieve them, even if plans change. Unlike the strict, fear-based leadership seen in movies, the modern military focuses on trust and empowering subordinates to make decisions.

In software development, this means explaining the “Why” behind tasks so developers get the value, communicating the “What” for guidance, and treating your team like a sports franchise by investing in their growth and fostering a supportive culture. This approach is said to boost morale, productivity, and job satisfaction.

I made a project management tool called goleko and I'm thinking about changing things up in my team. It's been a bit hard for me. Maybe this will help, I hope.

Have any of you used these principles in your teams? What strategies have you found effective in motivating and leading your teams?

Can I switch from cloud support to devops?

I am working in VMware cloud support role for almost 1 year and this is my first job but I'm already sick of this support role. I'm really much interested in devops and I have started learning some tools related to devops. But the question that really stands up in my mind always is can I really switch to devops from my current role or am I wasting my time. Can I get some thoughts about this? so that I can choose one right path with confidence.

Dose devops engineer take responsibility for making Dockerfiles?

Does devops engineer take responsibility for making Dockerfiles?
or Frontend/Backend engineers take responsibility for making Dockerfiles?


When devops engineer configure CI/CD pipeline, does CI pipeline include pulling source codes from git and building Dockerfiles?
or dockerfiles are just built by developers, and CI pipeline just pulls the dockerfiles?
