Work for a junior DevOps role?

I was hired for a junior DevOps role and my manager is letting me choose what kind of things I want to work on. What kind of work should I focus on to level up my DevOps career and make myself productive for my company?

So far I created some Prometheus alerts, scheduled CloudWach events with a script to clean out unused AMI and volumes in AWS, and created some infrastructure for an application using Terraform.

Available work consists of creating PRB with Jenkins for various things, Kafka things, ElasticSearch things, Prometheus and AlertManager things.

Upskill to DevOps or Python/JS?

I've saved up enough cash to give me 6-12 months out of work to upskill. My background is general IT (20 years), and I've done everything from roll-outs to integration to IT Management to building open source web development projects for NGOs. I love Linux the most, corporate Windows IT stuff the least. I'm average at networking, having to cram a full day on subnetting if I'm going to revise CCNA stuff, for example - I never remember it all.


I want to focus on DevOps or Programming now as I'm hitting the big four-o, and I would love to work remote full-time (I've done it before in short stints and currently do half the week remote). I want to self train rather than pay thousands for a rushed intensive bootcamp, only because I don't perform well in those kind of training camps.

What questions do you ask when you join a new firm?

So when you join a firm as a devops engineer, what questions do you ask to get to know the infrastructure? Apart from the techstack like cloud provider, docker, Jenkins, kubernetes, is there anything else that you should ask to get a in depth understanding.

Thank you and I hope this post helps new and experienced engineers.

The Ultimate Guide to Building REST APIs with PowerShell

Hey everybody,

I wrote a blog post on how to create REST APIs with PowerShell and Universal Dashboard. I included examples for retrieving parameters, processing files, working with XML and dealing with all the types of HTTP Verbs UD supports.

If you have any questions, let me know. I hope it's helpful!

Starting my first devops role in the new year. Just wanted to share.

I have been working as a system administrator for the last 18 months but teaching myself devops tools in my spare time.

I have also been building out Kubernetes in our dev environment at work, my manager wanted to explore whether it would be advantageous to the dev team.

I interviewed for some entry level devops roles in the autumn and after some negotiation am joining a startup to bring my slightly more ops focused knowledge to the team. I'm looking forward to filling in my knowledge gaps on the dev and process side of things.

I was brutally honest with the companies I interviewed with about what knowledge I had and did not have, emphasized that I was keen to learn and keep developing my skills. Seems to have paid off.

Very excited about it.

Any advice for hitting the ground as running as possible?

Should I Move To A City With Jobs?

So ... I'm a senior engineer and currently work remotely for a company. The city I live in has zero tech. I'd have to look for a remote job or move if I leave my current company willingly or unwillingly.

I'm at the age where i'm looking to settle down. Get a girlfriend, dog, look to buy a small place, etc..

Debating to just terminate my current apartment lease (pay the $3000 fee) and move to a big tech city and start fresh. My current lease ends in 10 months, Maybe wait it out? Maybe start the jump now?

I like the current city I live in as well as the two tech cities I'm debating to move to, Not sure what to do...

Would love any advice from anyone that has maybe been in.a similar situation, because I have this fear of settling down in a city that has no opportunity for my skillset.

Need Assistance with Cloudfront Distribution Redirects

Hey guys,


Looking for some help with redirecting a request from one AWS bucket to another domain.


i.e [app.domain.com](https://app.domain.com) will return the user to an Cloudfront distribution with a html file that does nothing.
What's the best way to redirect that traffic to [domain.com/docs](https://domain.com/docs) ?


So far using Lambda Edge, redirecting the request using 302 and location headers would maintain the url [app.domain.com](https://app.domain.com) and show some of the content, but accessing any other content in that cloudfront distribution causes issues.


Any advice for more advance routing stuff?

container running on my ec2 insatnce cannot connect to my mongodb (atlas)

Hey,

​

so i have created a cluster on mongodb-atlas and peered it with my vpc.
i checked that i can connect from a server to the mongodb and it worked - yay.

now, the issue starts when i run my docker containers on a docker-swarm that runs on the same server.
it looks like the containers running on that instance are not WHITE-LISTED by atlas. this is weird because the entire VPC is whitelisted.
somehow the container doesn't associate with its private ip.
did anyone else encounter the same issue ?
any ideas on how i can solve it ?

Is anyone using a vpn with Okta integration? What server product?

We are using Okta for SSO although not a lot of services are actually tied to Okta yet in our org, which I'm trying to change. One of these is the vpn, we've currently got a very manual openvpn process of creating signed certs and using an LDAP server that's tied to Okta for synchronization. It ... sort of works? Most of the time? At any rate, I'm looking for a real vpn server that I can run on AWS that's got actual Okta integration, but I'm not coming up with a lot in my searching. Anyone got options? I'm ok telling my management chain that we've got to purchase something rather than just rolling our own open-sourced solution if that's what it takes.

Where shall I begin

In the new year my major goal is to get a job in devops. I am looking for some advice on where to start.

Currently a Windows Sysadmin with about 5 years experience working in aerospace/defense classified networks.

I have a basic knowledge of docker decent powershell skills and a limited understanding of devops in general.

Where should I start here? I am considering getting the entry AWS cert and learning python after new year as a starting point. Would greatly appreciate any advice. I have read other similar threads but was hoping for some advice specific to my situation. Merry xmas y'all :)

Should I use docker swarms for "threads"?

I have 1 containerized app (docker). After it launches, it figures out what it needs to do on its own, then after 1-20min, the task ends and it shuts down.

My goal would be to have 20 "threads" running at all time. And maybe even adjust the threads depending on server performance. I've never used docker swarm not any other orchestration tool. Is docker swarm good for this task? Should I just use use a cronjob + bash script?

Multirepos vs. Monorepo: trying to create a product to manage many repos as there was only one. Any feedback?

Hi,
In my previous job, I worked closely with dev and devops, and realized that the choice of multi/mino repos was an endless battle.
Why not create a product that can reconciliate both worlds.
I’m thinking about a product where you can prevent writing to folders or files, or where you can play with the configuration of all the repos, as you were configuring only one (branch protection, ...).
What do you think about that?
I have a landing page, but I will not provide it to you, otherwise, you will think I m advertising for it. I just want to have a talk with devops people about that.
Thanks

DevOps at scale: challenges and solutions

I was asked to implement automation/DevOps at scale, where IT is far from being the core business. I don't want to go deep in the meaning of DevOps, let's say they're ok with automation and pipelines.
If you are in a big org, with thousand of services and apps, which was the biggest challenge? And how did you solve that?

Kops cluster having different enviroments that are mostly independant of each other

I have a KOPS cluster that I am using for two different environments called envA and envB which I'd like to have share the masters and then have affinity rules on my pods so that they only run on certain nodes. I was thinking that I could use instance groups and node labels? Would this be a safe solution or should I do the extra work and cost to have a differen cluster? I'd rather not but if it's my best option then I guess I have to, neither of the environments are production or external facing

China's cloud needs are growing at high speed, but is China ready for DevOps?

Local players like Tencent, Baidu, and Alibaba dominate China's cloud market.

While the whole world embraces AWS, Microsoft, Google, and other cloud platforms, Alibaba cloud leads in China and has an exceptional growth rate, with 47.3% of China’s cloud computing market share.

The problem is, China has strong regulations over the usage of the internet in a particular way, and their great firewall of China restricts most of the cloud companies to embrace DevOps. For example, you can't access the Docker images easily in China, and the distribution & collaboration of software seems pretty hard.

I recently wrote an article that should help some of you understand [how the cloud market works in China and how to enter the Chinese cloud market](https://hackernoon.com/cloud-and-devops-market-in-china-a-brief-overview-wcu30p8).
