Does anyone know how many Microsoft Developers work on GitHub vs Azure DevOps?

How about the future, do you see a time when all the Azure DevOps capabilities will be rolled into GitHub.

Docker Swarm getting going - Quintessential Questions

Hey Folks,

Coming into Docker Swarm from an absolute basics (singular, compose files) perspective, there are a few things I worry about and I want to know more. Any help that can be lent is great.

​

* 1) **STORAGE** \- In Docker Swarm, I see that you can define a volume driver
* A) where is this data bound to by default in a swarm?
* B) Should I be using shared storage like netapp or glusterFS with a Swarm?
* C) in a non stateless service deployment, where would I expect to see each containers data being stored among a deployment? (question similar to A but more particular)
* D) Are there plugins I should be using for storage? What is a best practice for stateful services/services which need volumes
* 2) **NETWORKING -** In Docker Swarm, I am going to have multiple hosts that will be hosting these services since that is what Swarm is all about
* A) What IP address should I expect my services to be available at?
* B) Should I expect Swarm, from an external network perspective, to behave instead as if I had a cluster of servers available and essentially load balance between a few of these? The difference being that I could have multiple different services running on the swarm as long as they don't use the same port?
* C) Can two stacks with the same port be deployed onto swarm or will that throw an error?
* 3) **ORCHESTRATION -** Are there common tools that are used with Swarm? If so, what are the most common ones that are recommended?
* A) [Portainer.io](https://Portainer.io) for any future onlookers is one I know personally

​

Thanks any and all!

Just putting this out there for now.. (asking for help)

Would any soul be willing to help me get a python app deployed to a kube cluster? I have a potential job offer and if I can get this app deployed, I think I would get the job. They are looking for a junior hire they can mold to the position.

I've been working on this since last Wednesday. I containerized my app and got the cluster up and running by Thursday night. Deploying it to the internet has been tough. I've tried a few different ways to deploy and I am trying out one more. It may take an hour to do so and if it does not work, I really need to call in some help. I feel it has something to do with my choice of CNI provider. I may have picked an old version... I'll report back and in the meantime, please let me know what you would need to lend a hand.

Mods, please delete if this is not allowed.

Best redirect solution without provisioning a software load balancer?

I need redirects (and sub url redirects) to a page, for example:

old.example.com -> new.example.com
old.example.com/test -> new.example.com/docs
another.example.com/testing -> new.example.com/docs

Trying to avoid using something like nginx for management overhead, considering using cloudfront+s3 bucket but this seems overkill and will result in a lot of buckets.

​

Any suggestions are appreciated :)

INTERVIEW QUESTIONS - tough questions to ask interviewer

Hey Guys,

I've got an interview tomorrow and I've been encouraged to ask the 'tough' questions to the interviewer. Things that come to mind are:

-What does success look like in this role?

-What are the biggest gaps you guys have today?

-etc.

Does anyone have any other good questions they like to ask during interviews?

Any suggestions and feedback would be greatly appreciated. Thanks!

Is there still a place for traditional cloud servers in the world of containers?

I’m fairly early into my DevOps career in (3 years). All of the applications I’ve worked on so far have run on containers, whether it’s ECS Fargate, Openshift or K8s. I don’t really see a lot of drawbacks to them, but I’ve also not got much to compare them against. The general trend in the company I work for also seems to be moving towards using containers for our projects. They just seem to be regarded as ‘better’.

Is this fair to say? Or are there still reasons to choose say, EC2 for running apps on over containers?

How many hours a day do you actually work?

Yes, it's been asked a million times but here we are. I cannot help but to feel bad sometimes for not being as productive as I'd like, to the point it kinda ruins my life a little.

From my side, I think I actually put 3 hours of work at most a day (in a 9 to 4 schedule). 1 hour spent on meetings, 1.5 hours actually doing work (whether that's writing documentation, proposals, automating something in Ansible, doing research, etc), 0.5 hours responding to emails and shit, and that's pretty much it.

I'd like to consider myself a decent DevOps consultant/engineer but I always feel like everyone is doing more than me.

Anyways, how many hours do you really work? Don't be shy, your manager won't read you :-)

Learn Minikube and Kubectl | Getting started with Kubernetes

Hey everyone,

I wanted to share this video I created demonstrating kubectl using minikube on your local laptop or machine. The goal of this video was to be "digestible" for those starting in DevOps, Kubernetes, Linux, etc.

I go into some detail besides some general commands and a deployment. I'll do a "deeper dive" video or blog post at a later time.

Here's the video; let me know what you think!

Observability and monitoring stack

Hey guys,

We are transitioning to a microservice architecture in my company and I have been testing some stacks out but still because I don’t have experience on it not sure what will work better in a more production environment. We work mainly in Azure, we also have AWS and GCP infra but this project it’s mostly with Azure Cloud.

Some of the technologies I have been gathering info on:

- ELK
- ELG (with Grafana)
- Prometheus (for the infra metrics)
- Log collectors - Fluentd/Fluentbit, Logstash
- Log aggregators - ElasticSearch, Loki

Between Grafana and Kibana, I found the second one slower but maybe it was my testing that it wasn’t great.

Also I’m basically trying to decide with the team if it’s better a cloud hosted solutions or BIY (build it yourself).
Like Grafana Labs or Logz.io, that would reduce the implication and issues with scaling out and maintenance I think in the long run, so I’m also keeping that in mind.

Sorry for the long post, basically I want to read opinions from people that have been working or worked with some of these and why they still do it or if they changed.

Thanks!

How can people even use Azure?

After just sitting with Azure for a couple of days I'm immersly frustrated with it.

It gives me a notification that the server has restarted, when it's in fact only restarting.

Most settings are hidden and unituitive.

Things work one time, then don't and then work again.

Manuals seldom work as instructed.

Seriously. When having the option to choose AWS instead at just a little higher price, how can people still buy this shit? It's a joke in comparison. AWS may be a bit complicated but it's always logical and the feedback you get from the system is relevant and updated.

Long term strategy for production deployment for a solo dev

I'm currently in a process of planning on going live with some of my projects. Till this moment I would test everything on Amazon Lightsail but for production I want to find something with more value.

I use self hosted Gitlab as my CI/CD pipeline together with Terraform for provisioning VPS's as well Ansible to setup fresh VPS where I finally deploy containers to the docker swarm.

I like Terraform but support for different VPS providers is pretty limited so I will have to consider that.

Is there a better process I should consider? The reason I came up with the above strategy was mainly finances and simplicity, it seem like this is the cheapest way to host and deploy on bare VPS. I'm just not sure if the long term this is the best decision from maintenance perspective when I'll have 5-6 projects running in production.

Plus constant rumors about Docker swarm not being supported for long also made me thinking if I should not look into things like Rancher or Nomad.

I'm in the spot where I could still make some drastic changes as long they're worth it in a long run

My biggest consideration was if I should maybe invest more money into some managed service as my deployment platform like GAE or other that would handled most of the things for me like self scaling, updates etc. to have more time for actual development.

I would appreciate some feedback! Thanks.

Computer Science to Devops

Current a CS student , planning my path to devops . No prior tech background .

-Would RHCSA be a must? Or basic Linux + suffice?

- Programming language in my school curriculum C++ , Java , python for machine learning ( would that be enough to apply for a devops position when I graduate or I need to attend a bootcamp).Is JavaScript or GO used often ?

- got my AWS SA

-working on Terraform Associate Cert.

-then CKAD .

Anything else I should add or take off this list please?


How much Linux do I actually need? Also already learning how to build a whole pipeline with devops tools on weekends.

Best free APM for beginners?

Looking to move into the DevOps space, but I'm curious about monitoring. What have been the free tools that you've had experience with (mainly infra monitoring, tracing, and code-level visibility) that you thought were worth learning? Here is my current shortlist I'm considering (open to more and curious of thoughts on open-source vs commercial products):

​

\-OpenTelemetry

\-AppOptics DevEdition

\-Elastic

​

I also want a free option, not just a trial. Thanks!

How do you use redis-benchmark util to fill up a redis cluster memory?

So basically I have a redis cluster deployed in AWS (Elasticache cluster mode) and I'm trying to run a util/test to have it's available memory utilization to fill up past a threshold to test my auto scaling. I've heard that the built in redis-benchmark util can be used to achieve this task but I'm struggling to get any success with it. Anyone have experience with this?

Goal: Use either redis-benchmark or similar util to write random keys/values to redis to fill up roughly 6gb of memory storage.

How to switch to devops?

I am an automation tester of 7 years experience. I want to switch to devops as I am pretty bored with testing and want to learn something new. I am half way through learning all the necessary stuff like docker, kubernetes, Jenkins, git, nagios, linux and scripting with python. Basically doing all the starter devops learnings.

I cannot switch in my company to a junior devops position as I can't be released from my project.

I want to get hands-on experience before I try outside.

Also, if I am to try outside my company, what experience do I put.? Do I join as a fresher?

Please suggest. Thankyou

Replicate EC2 instance in packer

I'm currently facing a small issue at work where I need to change the way we manage EC2 Ubuntu instance.

Currently that instance is responsible for running number of different services and background jobs and the only thing that changes on that instance is the source code. There are no updates to packages or services running on that machine.

I know mostly what is running on the instance and I can get more details about the instance from the devs. However, I suspect that even if I do that and create packer build from it there will be few small things that will be missed and therefore the instance will stop working correctly.

What would be the best way to accomplish this?

Google just legit sucks to try and contact regarding Dev to Dev issues.

So, I'm a dev, and I'm trying to contact Google.

So, apologies for the rant.

However, we don't have a specific contact there for our needs. So, I have to legitimately try every single which way to get a live support person that seemingly does not exist.

Apparently, the Android platform is adding pixels to the device instead of changing the pixel location on a browser page.

So, this creates an issue where it causes our platform to refresh. However, this causes a bug if we remove it \[which we plan to do interim\].

So, we're trying to create a trouble ticket for them to address the problem.

***\*Crickets\****

So, meanwhile, this is seemingly common place. So, if you have the same issue where normal interactions cause a window refresh, this is likely the root. Though, sorry I can't get anyone to address it.

How do you manage resources like servers, accounts, accesses, switches?

I imagine most of you here work on bigger infrastructures with multiple resources involved. How do you manage all that? I hope not by using the spreadsheet or sheet of paper...

Are there any tools out there designed for managing servers, accounts, accesses etc? By managing I mean things like tracking IP addresses of the machine, perhaps MAC addresses or the hostname, the spec of the machine, software that runs on it, logins & passwords, ssh keys, physical location etc.

Same question about using accounts, e.g. 3rd party online accounts like gitlab / github / you name it within the automated, headless operations of the infrastructure. How do you manage credentials, billing etc.?

sentry.io - almost exceeding transaction limit

I have a new web app and I'm monitoring it with sentry.io. This is my first time using sentry and I don't know a lot about it, nor am I an experienced devop. I implemented sentry to catch errors on my website. I'm now up to 80% of my transaction quota.

I suppose that at some point I may want to look at performance monitoring but I'm not there yet. I don't know how to turn it off, or how I would limit which types of transactions are being monitored. I think my website sees very little traffic. Over a month I'll record maybe 100 transactions a day and every 3 to 7 days I'll get a day with 800 transactions.

​

The email warning I received from sentry suggested I look at this webpage to "manage my event volume": https://docs.sentry.io/product/accounts/quotas/manage-event-stream-guide/?utm\_source=sentry&utm\_campaign=quota\_notification#-how-can-i-see-a-breakdown-of-incoming-events

but I understand very little of these instructions.

I'm hoping someone can get me started in understanding how I can limit the transactions, and also what I might want to do to manage my event stream.

thanks

Where should Jenkinsfiles be stored using Remote Jenkinsfile Provider Plugin?

My team is in a peculiar situation where 1 jenkinsfile will run different repos. This is due to the portability aspect of each repo and how alike the build process is for each. We didn't want to duplicate the Jenkinsfiles and maintain each one by storing them in multiple different repos. So we are deciding to place the Jenkinsfile in their own repo and just use this plugin Remote Jenkinsfile Provider | Jenkins plugin.

However, what is the best practice when doing this? Should they just be contained with our Jenkins Shared Library repo? Or should they be in a separate repo?
