Short Q & A

Hi,

I'm looking to get into devops by following the roadmap on well...roadmap.sh (Do you guys have any other suggestions? I was a Business Analyst for 2 years and now I just started as a System Integration Analyst so I don't really have any devops guy to ask for guidance for now)

One of the questions that I'm fighting with is what hardware/software combination do I need? Should I go for a Macbook or should I just get a ThinkPad and drop Linux (LTS?) on it?

If you learn GCP, can you transition afterwards to AWS for example or are they just super different niche options?

Should I go for Python? GO? Is there another good option and how long of a beard (read this as experienced with the language) do I need to grow in order to land a junior position?

Are there any specific certifications I should look into that you also help me learn?

Recommendations for sast, sca, static analysis services (SAAS only)

I've been fiddling with Snyk for a bit and it is clunky as all get out. Also, there's a big price jump if you want to user the SAST product.

I do not want to manage/host my own tool, I would prefer to use a SaaS product. Any and all recommendations are appreciated.

OneDev 6.0 - self-hosted git service with CI/CD and issue board

OneDev is an open source self-hosted git service with built-in CI/CD and issue board.

The 6.0 release comes with some major improvements:

### Hierarchically organized projects

Projects can now be organized hierarchically to facilitate permission and setting inheritance, as well as cross-project issue list and board

### Issue burndown chart

For milestones with start date and due date specified, OneDev will display burndown chart for associated issues

### In-place edit of issue states and fields

Issue states and fields can now be edited in place in issue list and board, which makes issue editing much more convenient

### Issue link

Issue link to set up relationships between issues, such as parent-child, blocking/blocked by etc. Issue state transition can also leverage the link information to make the workflow smoother, for instance, to auto-close an issue if all its sub tasks are finished, or prevent an issue from being closed if any issue blocking it is still open. For details, please check this tutorial

### Helm chart to deploy into Kubernetes cluster

Helm chart now available in case you want to deploy OneDev into Kubernetes cluster

### Ingress and LetsEncrypt integration

When deployed into Kubernetes cluster, now it is trivial to set up ingress rules to expose OneDev web service, protected with LetsEncrypt certificate. For details, please check this tutorial

For details, please check https://github.com/theonedev/onedev/wiki/6.0

GCP execute api call based on alert

Hi, I want to configure some automation when memory usage on my GCE instance is above some threshold, basically I want the alert to trigger some Cloud Function to call an API or maybe there's a better way to do it....please share if you have previous experience.


Thanks!

Why Linux is needed for DevOps in 2021?

This question come of course from a total noob. Please, do not be harsh on me. I just could not find detailed answer and some people that I know, don't use linux at all and while they are not 100% time DevOps, they never needed a linux on their PC. Maybe this is true only if you are doing only some basic stuff and you are not full DevOps guy?


As far as I know, most stuff just works on Windows right now (docker, kubernetes, ansible etc). Do they works much better on Linux tho? Is there anything that just does not work on Windows and just require Linux?


I know that most of the cloud run on Linux but if you are working with AWS or Azure, you still work with everything by using either AWS or Azure portal or this looks different and for example you need to use console a lot and thus ssh to the server etc?

Recommended course to get into Python scripting & automation for AWS Cloud and DevOps? (as a Javacsript Dev)

I learned to code Javascript and Node.js from a Udemy course and made a couple webapps, but then found my real love in this field in cloud computing and networking. Got certified with AWS as a solutions architect. Found out many AWS jobs are asking for Python scripting skills with AWS. I was really interested in learning Golang, and I see some demand for it, but most jobs I'm applying to ask for Python scripting and automation specifically.

So that being said, I don't need to relearn programming basics like what a variable is or how to do a loop. I also don't want to make a web app or game with Python - I need to specifically learn the scripting, devOps and cloud automation side of it. Can you recommend any courses for this specifically (and as someone who already has programming fundamentals). Something that can get me hands on Python scripting training for SRE, Cloud, DevOps and SysAdmin work with Linux etc and fill the gap in my knowledge to prepare me for working on the job.

Is security through obsolescence a phrase?

Because Log4j shenanigans, had to check some services. This service is 5 major versions behind and has no CVE's - and has been on my hit list for "Why the hell haven't we updated this", but our application code can't handle the 5 major version changes.

Security through obsolescence FTW.

I started learning GoLang so that I can write Kubernetes Operators and API extensions but...

... will this knowledge and skills really help me with my career or any project that I work on?

Personally I think that if I have the ability to use GoLang:

\- Fix/Patch operator issues

\- Write custom solutions that are directly bound to k8s

\- Write my own operator and easily administer projects

\- Learn Test Driven Development with Go

\- Be closer as ever to developers and understand their needs while developing the apps

Is this right and should I stop and go to Kubernetes only specialization or this path is possible in companies as a normal DevOps or DevSecOps job?

How rare is it to get a job in US if you currently work in a different country?

If I wish to settle in US since it provides a better lifestyle for me for various reasons, can I get a job there if I currently work in a different country? Or is it too rare to happen? Is it more beneficial if I do a MS in US and then get a job?
I currently have 1.5 years of experience in DevOps Engineering, there's still so much to learn and I continue to do so. But, the thing is, I don't want to study MS for 2 years if I can get a job based on my experience.

My question is to those who are currently in US who have relevant experience to answer this question, and also to those who have achieved this case!

Logging in Offline mode

Hey gang!


I have a use-case where I have unix hosts (IoT devices) which are deployed on a customer's premises. I would like to capture logs and telemetry for them. Sometimes these devices are *not connected* to the internet but are still in operation. They can be "offline" for weeks (still assessing if that's how our users actually use them) while still being used. How do we buffer and forward these logs to a Log management service? Datadog and CloudWatch will reject logs with a timestamp older than 24h.

​

How might one architect the logging pipeline with this in mind?

I'll post some of my own thoughts but wanted to leave the conversation open and unbiased to start.

How do you keep organized?

I was trying to think of the subreddit to post this in. This isn't really the right one, but I've worked with DevOps & IT people for many years and I know they always have like fifty different things to do, so I guess I'll ask here.

I work for a small nonprofit. I'm a Linux server admin, a webmaster, I take support phone calls for both employees and customers, I manage livestreams from the company, and I manage google analytics and adwords for the company. The way the work load is balanced in the company, there is simply no one else to take any work off my shoulders, and that's fine. We're all very passionate and believe in what we are doing.

I work within a team of three, but I more or less have complete autonomy. On top of that I have a one year-old son, I take care of my one year-old step-granddaughter, and I have one more baby on the way. That means I really only get five hours of focused work a day (when we can afford to have a babysitter here). Beyond that I have 2-4 hours of work where I'm simultaneously cooking, taking care of children, etc. Beyond that, I have tremendously bad short term memory, to the point where sometimes forget what I'm doing as I'm doing it. No it's not some horrible brain illness, stop worrying about me, I've been dealing with it for most of my life and I'm fine.

Okay, all that aside: my life is chaos. And every attempt I have made at organizing it has fallen apart. To do ist, calendars, sticky notes, all that shizz - it's not enough, often times because I forget where I put what I was doing. I don't know how to prioritize or how t learn how to prioritize tasks. When I look around, all I see is fires to put out, and not enough time to do it.

The only time I have really been successful is if I get myself into a routine and execute that routine every day. But the problem that I'm having is I have to deal with so many fluctuating variables that I never establish a routine.

So I want to ask -- you professionals out there in demanding companies that want you work functionally thrice as much as you are physically capable of - what tips and tricks do you have for being organized and getting your work done?

Thank you.

Is there any tool to create diagrams with Git Branches? Something like PlantUML?

I am looking for a tool to design git branches flows declaratively, like PlantUML or something.

I know I can do this in tools like Draw.io but I wanted to do it via "code".

Does anyone know of any tool that allows me to do it?
