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.

Help understanding the point of documentation

Will preface by saying I get the point of BRDs and things like relationship diagrams but i dont get the point of things like documenting what fields are in the database since most databases do a great job at having these things properties easily accessible with descriptions, data types, et Al.

Despite this i often have sr managers request to have things documented in areas outside of the system. Just curious when these types of documents come in use since they're always requiring updates and are a considerable lift to maintain and update on top of the dev work.

Designing a DevOps tool chain maintenance activity

Hey there,

We have tools like Jenkins, GitLab, Artifactory hosted in different Azure VMs as Docker containers. Every week we have to restart the containers as per a process. In detail, these have to happen for each tool.

1. Check if the local files for the image are up to date with the remote repository
2. If not, pull the latest code.
3. If there is new code, build the image again
4. Docker compose down
5. Restart docker
6. Docker compose up


At the moment, we have done this manually by SSH ing into the server and executing the commands. But I am thinking of designing a automated way to handle this work. I am wondering what is the best way to do this process automatically ? Is it possible to do something like a Jenkins pipeline or do I need to go the Ansible/Rundeck route ?

audit.log and cloudwatch agent

What timestamp conversion code are you guys using for the auditd log file? Epoch time seems to not be supported, they all come through as one entry with many actual log lines. It seems like the audit log would have been an important one to support out of the box.

How many micro services does it take to run your App?

Just a quick ask trying to find out how many micro services does your app need to run. That is if you are using micro services. The app am currently supporting uses about 70 different micro services. All I can say, I miss the monolith.

What's your greatest DevOps learning in 2021?

For me, this is what I learned,

Jenkins is not the only CI/CD tool
Security is getting more attention and obviously it has to
Kubernetes is winning all over
DevOps is NOT A ROLE, stop calling people DevOps Engineers
The use of AI and automation in your SDLC is so cool
Just using Git and pushing/pulling things is not GitOps

Share yours!

LOG4J shell from a devops perspective

Helle dear devops guys,

I want to know as devops guys what are our responsabilities facing log4shell vulnerability? How should we react and what we need to add in our CI/CD pipelines ? In our nexus repo? Etc.
Untill now i just wrote a shell script that defined all our apps that use log4j 2.x and 1.x , and it's up to the architect to decide if we should upgrade or not, but beside that what can i do more as a devops engineer ?

Thank you all,

Question about blue/green deployments with databases.

I'm unable to fully comprehend best procedure to implement database migration between the two environments. Wouldn't there be data discrepancies between blue and green? Should I be using database replication between these two so the data is always up-to-date? Most blue/green strategies I read deals with applications deployment but lacks on how to deal ⠀with data. Any input is appreciated.

Structuring internal documentation or product/project?

We have several projects/products mostly for B2B customers. Internally we use Confluence for documentation all sorts of decisions, processes, architecture, operations guides, research, security, high level, etc..

Our documentation can still be a mess, with many documents covering multiple aspects that makes it difficult to organize.

How do other people structure project documentation that makes it easy for not only your team to find things, but also business people, and devs from other teams so they don't bug you about "where do I find X?"

How to use hetzner load balancer in kubernetes running in hetzner cloud?

I've set up a new kubernetes cluster on hetzner cloud using kubeadm. I have 1 master node and 2 worker nodes, they are up and running. I used Cilium as the CNI plugin and Traefik as ingress controller. The problem is related to load balancer services - how can I use the hetzner load balancer with them? I tried setting load-balancer.hetzner.cloud/name: "load-balancer-1" to the traefik load balancer service, and even specified loadBalancerIP pointing at the created hetzner load balancer.

Nothing seems to work.... Has anyone managed to get the hetzner load balancer working with kubernetes?

Multiple Interview Rejections, feeling a bit bummed, looking for feedback...

Hello Everyone,

Over the past few months I have been interviewing with several companies (around 10) for a variety of Cloud and DevOps roles. Unfortunately, I have been rejected or declined from every place I have interviewed at so far....usually after the technical interview portion (no problems with the culture / fit interviews). I am trying to remain positive and look at this as growth opportunities to identify what gaps I have and what I need to study up on (mainly things like containers, Ansible, Python, etc. to be specific) and plan on spending some time to study over the next few months. I also know that at the very least this is giving me some interview 'practice' since I have been at my current job for the past 5 years and have forgotten how to interview if that makes sense. But I am just feeling kinda shi**y about the whole situation to be honest. I was hoping throughout this '1st round' of interviews I would get at least one job offer.

Anyway, not trying to turn this into a pity party. But really I just wanted to ask if anyone out there is in the similar boat? Are there other things I should be concentrating on to get better or to help grow myself? I am thankful that at least I am getting the feedback on what areas I need to improve on, and not just the generic "sorry you weren't the right fit" response from the recruitment teams. And the bigger relief that I still have my current job that I can fallback on throughout this process.

Any feedback / thoughts / advice would be greatly appreciated. Thanks!

I can't run these commands

wsl --shutdown
wsl

and I get cannot find the application, don't have permissions, which is weird. I am using wsl2. I think it works on powershell if I remember, but this is really weird.
