As a software engineering student how do I do DevOps

I am a SE student taking on a Capstone project class where I am assigned to a startup company. I have to figure our how and where to host their single web application and MySQL server. I know each choice is circumstantial so how do I make a decision based on my needs. I don't even know how much storage I need.

Requesting a roadmap to a Big 4 SRE

Hey Reddit,

​

I've posted here on/off for a couple years now. I'm at a point in my career where I'm starting to specialize in a specific job (monitoring, alerting, and log aggregation) and I'm starting to get pigeonholed into it, but also despite several attempts to negotiate with my employer I have not received a significant base salary increase since I joined. Furthermore there are some unsustainable engineering practices we have that I simply no longer wish to participate in and I think it's best I begin to consider other employment options.

Although I understand the fundamentals of DevOps, I think my current skillset is more suited towards some flavor of SRE. I've identified several new skills and concepts I will need to master in order to be able to efficiently transition to a new role (specifically one at a big company) and I've already began studying the interview process.

I just wanted to ask Reddit in general for some advice: What skills would YOU say could get me a general SRE job at a big company and how competent should I be in them? Also, what skills do I need to master to ACE an interview? Would mastering the DevOps roadmap and data structures/algorithms be enough? And for recruiters out there, are there any skills that would really make a candidate stand out? And what skills do you find candidates are too weak in?

Thank you for taking the time to read and respond :)

Using DevOps for Business Development

I know DevOps is not for this purpose, but what do you guys think about using DevOps for tracking account leads for business development? Like creating Epics for different projects that you are trying to win, and creating child issues linked so everyone can track the conversation progress easily.

Some of our colleagues use excel and powerpoint for tracking BD efforts, but this seems a bit old school.

Hoping for a constructive discussion or ideas to improve on this topic.

Inspec vs Twistlock

I was going through various compliance check tools, inspec was the most popular choice out there. But we do use twistlock in our team for vulnerability scanning and I see a compliance check there too.

Is there much difference between inspec and twistlock compliance checks other than former being opensource where we write compliance checks as controls and latter is a paid one already with all compliance checks present ,we just have to run it against the hosts we want to be tested.

PSA: Accidentally get a big charge in your Azure deve account? Microsoft may waive it if you ask!

I recently left some resources I was testing running in my personal Azure dev subscription.

Racked up about $100 in charges before I remembered and removed the resources.

I contacted Azure support and asked if they could waive the charges since I left them running accidentally. They agreed immediately.

So don't hesitate to contact them if you have some big charges! Probably worth a shot with AWS or GCP but haven't tried personally.

Moving from network engineering position to DevOps / software positions

​

Hi,

I'm a 23 years old network engineer with 4.5 years of experience at enterprises, I have the following knowledge:

\- Cisco networking - routers and switches also all the protocols.

\- Python scripting and network automation

\- Linux system administration

(not system admin experience but from network engineering perspective).

\- AWS fundamental knowledge

\- Check Point firewalls

\- Virtualization - VMware

​

These are my certs that I currently hold:

\- CCNP R&S

\- CCNA Security

\- AWS Cloud Practitioner

\- LPI Linux Essentials

​

I currently want to pursue a career in devops/SRE/software development and I'm not sure what is the best path for me.

I think about starting to pursue a CS degree because I didn't go to college yet, but I got another feeling of doing AWS Solution Architect associate cert and Linux cert and go more to the "devops/SRE route"

(also learrning docker + ansible + jenkins afterwards).

​

I'm not sure if my best way is to pursue a CS degree or get certs for a better position (Devops/Software)

​

Also I'm kind of wondering how to advance my skills in order to become devops engineer / SRE.

If someone can structure for me a learning path in terms of subjects, I can learn and also do labs and test for myself.

Also what are like the best tools for devops? I heard that AWS + Linux + Ansible + Docker + Kubernetes and Jenkins/TravisCI are the most common.

Thanks,

Alternatives to Redgate for SQL Database Automation

we've been using redgate software to automate our sql build and deployment practices for a few years now; however, they changed their license model a couple of years ago and its incredibly expensive now on a per-user basis.

The redgate tooling works very well for us combining sql source control with the DLM automation tools, the flexibility the filter files and comparison options provide is pretty important as we have close to 100 different databases, many of which have some specific deployment requirements to ignore particular objects. The comparison reports it generates are critical as well to provide visibility into changes being made. These are all features that fall into the 'must have' category for us. The other nice thing about redgate is that it actually generates all the code when commits are made so we have consistent SQL code across all our databases.

​

Would love to hear any suggestions you have on alternative tooling or approaches to full automation around the management of SQL Database schema and data.

Migrating to Helm 3

Hi all,

I've recently finished migrating our environments over to Helm 3 (goodbye and good riddance Tiller!). I've written some blog posts that documented some of the pitfalls I encountered when updating our scripts for Helm 3, as a lot of the flags for Helm have changed, and some don't even exist anymore.

There's also a great blog post by the Helm developers that explains the migration process from a high level. One thing that was missing is what to do if you find yourself wanting to roll back to Helm 2. How do you delete releases once they're migrated to Helm 3? Conveniently enough, release data is stored in k8s secrets now, so it's pretty easy to do.

Anyway, hopefully these are of use to some of you.

Kubernetes pulling wrong image

I have an issue where kubernetes is pulling the wrong image from ECR. Issue pretty much is serviceA:tagX has Image ID of ABC then serviceB:tagY has an Image ID of ABC as well so Kubernetes is deploying the serviceA image for serviceB. I'm using helm charts and right now am deploying manually (for now) via setting the tag as a values.yaml param. What can I do to prevent this issue from coming up again?

Puppet tutorial/book recommendation

Hey guys,

So I just got an offer letter today for DevOps position (yay!) and the team uses Puppet for their configuration management. I am trying to prepare myself for the role as much as I can before the start date and wondering if anybody can share resources for learning Puppet.

I have been using Linux Academy to learn RHEL/Git/Ansible and I liked them all so far but I do not like their Puppet tutorials.

I would really appreciate your input!

Checking what an upgrade will break?

Hi, I'm looking to upgrade some software at my current job, but I want to do it with minimal breakage.
In this case, it's Jenkins, and it's a big jump forward(our version is 2.2xx.3, newest appears to be 2.7.x).
Is there an aggregator of change-logs that will tell me what this will break? I don't want to go in blindly since that would be a huge pain in the ass.

Does anyone know a way to pass a file to a remote instance using ssh forwarding?

I'm using Terraform to instantiate and instance and It always generates a new instance with a new hostname. I wanted to pass a DNS value from a file using SSH forwarding to automate this process. does anyone have an idea? I'm thinking something like this.

cat efs_dns.txt | ssh -A ec2-user@$$(terraform output bastion-public_ip) ssh master.openshift.local

Here’s an idea: a 3D VR world of your Kubernetes cluster

Pods, containers, services, deployment, logs and live traffic visualized in a 3D space that anyone can move around in. Useful for debugging.
