How do you use Go in your DevOps job?

I'm pretty proficient with a few languages, however Go has recently caught my eye and im learning the basics.

I know they say Go is up their with Python as the big language for DevOps Engineers.

What are some ways you are using Go in your job?

(I know popular tools like Terraform, Docker and k8s are written in Go. I'd like to exclude these, as it isn't very relevant what language these tools are written in unless you are a contributor to those projects)

Developing is hard

I am slowly starting to appreciate all the apps and websites i use more and more lately. The fact that everything works almost perfectly without breaking is very impressive. Reddit is a huge feat. The iOS is a remarkable piece of technology. I appreciate every single one of you. Our work is literally shaping the world.


Good stuff everyone.

Today I learned "Signoz architecture is more simpler than Prometheus+Cortex"

One of my AWS client's (a gaming company) was searching for APM and decided to do POC with DataDog, after reading /researching a couple of days I understood DD has more complex & heavy pricing. So I turned towards open-source mainly Prometheus and Grafana, but since it isn't the case of "one-size-fits-all" I was still diving deeper in open source and came across Signoz an open-source APM based on OpenTelemetry component. If anyone has used Signoz please let me know your views about it.

What do you do (as a junior) when you're new and cannot learn the systems without help but your entire team is too busy?

I'm the only junior in a team of nearly 10.

Been here for almost 2 months on my team. I've learned a few things about our systems. I was new to the vast majority of the technology. I've had about 4 short sessions 1 on 1 for anywhere from 10 mins to about an hour. The problem is that the complexity of this system takes at least 5 or 6 months (according to team)...and that's for more experienced people than myself. And no one really tells me to do anything or helps unless I ask and manage to find a free slot in their schedule.

I feel like I'm not doing much a lot of the time. I look over the ticket I'm working on but I've reached the farthest point I could get to without guidance. The other team members are working on much more important things than this ticket.

At this rate, I'll never learn enough to contribute, learn our systems and function independently. Not sure what to do.

EC2 vs Lightsail

If my plan is to have a Wordpress blog with 20-40 multi sites each with a few plugins, do I go all in on EC2?

The first multisite is already bogged down on crappy $7/mo shared hosting. Is lightsail going to be enough of a step up today? Is it going to be very expensive to switch from lightsail to ec2 in 5 months with 5 or so multisites up and running?

Can somebody link me to an article as to how I can learn about server usage? They talk of on demand hourly rates and network performance in gb’s used.


Hoping to learn a bit today! Love resources if you can point me the right direction!

Bachelors in IS or CS

Hey all,

I'm looking at continuing education. I currently have an Associates in Computer Systems Administration and have been a DevOps Engineer/SRE for the past 5 years. I was wondering if I should continue down the IS path or branch out and go down the CS path.

I want to continue working in the SRE/Cloud space but I do know my shortcomings are around development (Python, Go).

Would love to hear everyone's feedback.

Which Macbook Pro 14 inch configuration to get for DevOps?

Not sure if the 14in base model is sufficient or if I should upgrade the RAM and GPU? Problem is the upgrades are costly. So I don't know if it's worth it or even needed in the first place.

Setting up on premise cloud on windows mini pc for learning & keeping up my nextcloud instance

Hi guys,

I recently bought a low profile J4125(2.0GHz up to 2.7GHz) Windows 10 Mini computer RAM 8+256GB Ssd

While i want to learn vagrant and terraform.
I have some very basic questions:
I have some insight of using vagrant in past, however i want to know can I use vagrant on my linux laptop to spin a vm instance on windows machine remotely?

Secondly, All the videos on internet shows terraform deploying infrastructure to linux machines , can terraform be used to deploy virtual box instance of ant OS? Or i would need to use vagrant in between? I am aware of provider concept in terraform. But i dont quite get browsing trough the world wide web how virtual box provider will spin instances using terraform! 😕

Cannot get podman to work

Hello, I just installed podman with Homebrew and can't get it to work. I can search for images on docker.io but I get 503 errors when I try to pull them. I need to use --tls-verify=false because my work has deployed Zscaler, which basically injects its own cert.

% podman pull --tls-verify=false docker.io/library/busybox

AWS SNS for phone number verification (OTP)

Hello folks, we have a mobile application that we want to use a phone number verification mechanism such as OTP to verify users before signing in. For the backend we are planning to use AWS SDK to interact with the AWS resources that are needed for this. We are thinking of using SNS for this purpose but we aren't sure of all the things we need around this to achieve our goal.

What we are thinking;
\- Create SNS Topic and Subscription with SMS Protocol
\- Create a DynamoDB table to store the OTPs.
\- Use AWS SDK to interact with the resources.

We aren't sure whats the best and easiest method to achieve this, will we need Lambda functions or the backend can handle this process using the SDK? We're very open to suggestions.

Help Maintenance Page, What's under the hood?

TLDR;I want to have customers to be mapped to a Maintenance Page during the release while allowing the team to access the web applications for testing.----

Our PHP Laravel application is hosted inside EC2 on AWS behind an Application Load Balancer and runs Nginx as a Reverse Proxy.

I am tying to find the best practices for enabling and disabling Maintenance Mode on our web application. The way I do it now is by having an ansible script to verify a static page that Says "Maintenace time blah blah blah, we will be back soon." on the production servers, then change Nginx config to map requests to the static page, and finally turn off the Backend (PHP Laravel).

This approach works perfectly but we are facing a hard time smoke testing the application, each time we have to turn off the maintenance mode, start testing, and if we find something we turn it back on and deploy a hotfix.

The question is how the process/setup should be under the hood so customers always get maintenance but our team is always able to access the application during release? What are the best practices for maintenance?

Learn programming

Hi everyone,

I want to move a step forward DevOps/SRE world.
Currently I am a senior system administrator, I gained lot of experience with Linux, containers, Kubernetes and cloud

I think it's time to introduce some programming skills, I see a lot of companies are requiring this kind of skill for DevOps/SRE positions.

I'd like to start my programming journey using Go, but it's difficult to find some books/resources for a newbie like me

Do you have any suggestion?

SWE has eaten ops, DevOps and SRE. <rant>

&#x200B;

I've been working in tech for almost 20 years, I'm 37. I'm self taught and did not go to college.

I started as a minimum wage tech support rep, became sr. tech support, been an I.T. admin, linux sysadmin, SRE and Sr. SRE and now working at one of the biggest tech companies making 250k in total comp.

I'm very fortunate in having gainful employment at a high compensation level (relatively speaking), considering my lack of formal education and meandering path I've made through life (I had terrible drinking problem until age 25, sober 12 years now, and I was an aspiring semi-pro musician throughout my 20s, not always working).

Right now though, I'm extremely discouraged and frankly kind of annoyed.

I've just done several full-length job interviews for SRE roles at companies that I think are cool (well funded startups), and keep getting told the same thing, which is essentially:

"What we really need is an SWE who has the title of SRE".

&#x200B;

I feel like I've shot myself in the foot a few times mentioning that I consider myself to be a Devops/SRE professional and not a SWE in these interviews (after all, that IS the job I am applying for right?) to one person that then raises this as a red flag during the interview debrief or something.

&#x200B;

I do write code. It's just not the main thing I do, and my SWE colleagues are admittedly much better at it than I am, because that is what they spend all their work time doing. But I am much better at pulling everything together (IaC, pipelines, observability) and making sure it's running in a sane , scalable, and repeatable way.

&#x200B;

Perhaps my experience is not representative of the overall market. I feel like there is or was a time not long ago when SRE was fetching more $ than SWE because the breadth of knowledge required. I'm just not finding this to be the case, if you want to be an SRE it doesn't matter if you have years and years of UNIX/Linux, networking, ops etc, background, maybe you are better off just having a CS degree and 1 year of experience, and "knowing" kubernetes.

&#x200B;
