I'm an IRL DevOps Eng and was curious if my problem would interest you?

I thought hey- since I know there are readers of all sorts on this subreddit, from starting out to experienced vet, I thought this might be a nice idea to illustrate a fun problem I'm having to see if anyone wanted to give it some thought?

I've got a Jenkins Server running in Kubernetes. I have a Bitbucket server (internally). I am not able to connect to Stash via the"Bitbucket Server Integration" plugin... and the issue seems to be with certs as per the error raised in the plugin, however I have verified my certs are correct in the truststore for the Jenkins container inside my pod (remember, it's on kubernetes)... so, what do you think could be the issue? ;)

Goal Setting is Bullshit: Try this Instead

“Set goals and you’re set for success.”

These might be the exact words that you would hear across the internet from the millionaire gurus while you procrastinate thinking of your goals. You might even have a diary that has your goals listed and defined. But what’s lacking?

Object and Block Storage: How They Differ?

The difference between block and file storage makes heads spin due to the complexity of definitions and technical jargon across the internet. Even a technical person sometimes forgets the business value and makes decision fatigue their best friend when trying to figure out the value proposition of

basic questions about getting into devops career...

Hi. Thanks for reading. First a little background about myself.

- Mid 30's
- 3 years exp as Software Developer mainly using JS.
- Some experience with other programming languages including Python and Java.
- Experience creating basic Docker containers, CI/CD (CircleCI), deployments on Heroku and DO.
- Just above basic linux knowledge (Fedora is my main OS)
- Previously passed CCNA (I still remember some basic networking concepts)
- Read the Phoenix Project

I was contemplating switching to a more DevOps role but had a few questions first. I've already done an extensive search for answers but would like some further clarification:

- How common are Jr/Entry level DevOps roles? Would I be considered for a junior role given my skills and experience?
- How difficult is it to learn some of the DevOps related tools such as Ansible, Kubernetes, Terraform?
- True or False: DevOps usually requires on call.
- What's the best way to practice and learn all of these DevOps tools? What should I be building and demonstrating in my projects?
- Which cloud service is best for beginners to practice out of the Big3 - Azure, GC, AWS?
- How much programming do you actually do on a day to day?
- True or False: DevOps is typically a thankless job.
- How accurate is this roadmap?
- What programming language is most useful for a DevOps role? The roadmap says Go.
- True or False: DevOps is typically more stressful/high pressure compared to Software Dev and other tech related roles.
- How much do certs matter?
- True or False: DevOps is basically Softare Dev, Systems/Network Admin, SRE all rolled into one.
- Do you feel any job satisfaction?
- Anybody want to partner up and learn all this stuff together?
- Are any of your companies in Canada looking for a jr/entry level Devops? If yes, feel free to send me a PM.

Thanks ✌️

What Techs Should I Use While Moving from a Monolith To Microservice Architecture?

I know there's no right answer, I'm just looking on some input to use in helping me create arguments for which techs to use. My company has developed a very large application in a monolith using an early version of Grails (2.3.11). This has caused a lot of issues, including not being able to really upgrade Grails in any way even though the current version in 2 major version ahead, and there is some HUGE reworking and additions of really nice features we've never gotten to use. That and a couple other issues have caused us to want to slowly adopt a microservice-based architecture instead (We know we'll never be able to really FULLY move the app all the way to microservices, but splitting out as much as we can will help a lot).

We've always just built (either manually or through Jenkins) the .war file and uploaded it to EBS. I'm trying to create a game plan for moving towards microservices that sets us up for success as early as possible. Right now my gameplan is to start with containerizing the current application and deploy it that way, then it becomes easy to create the "first" microservice in another container and not be doing a whole lot of building it in the main app and potentially causing issues at one time.

I wanted to know if anyone had any good articles or stories of their own on moving from a monolith to microservices that were built similarly. What opinions do you have on using EBS even with microservices? Should we move to all EC2 instances early on? Should we try something like EKS? Do you like Docker over K8s or the other way around for some reason? Open to all information.

No, you can't do it better in Python or bash (challenge)

Doing DevOps today? 99% either abuse bash or abuse a general purpose programming language.

bash does not meet any modern expectations from a programming language: syntax, error handling, data structures

General purpose languages such as Python, Ruby, etc are not domain specific enough to have the desired facilities.

Here is small example of straightforward solution to a small problem: list all CloudFormation stacks that are managed by the given CodePipeline.

Your are welcome to prove me wrong about this particular example - come up with at least as clear and as concise solution in either bash or Python. I think it can not be done.

Domain structure for multi-cloud, multi-environment

Are there any articles/docs that reference planning out a DNS structure for multi-cloud, multi-environment setups? I've tried searching out there using different terms that I can think of, but I'm not finding what I need. Here is the basics of what I'm looking for information:
- How to structure private and public dns structures to support multiple environments (prod,qa,uat,dev, etc), that will run between multiple providers (onPrem, <insert cloud providor here>).
- Would adding several subdomains allow for easier scaling in the future, albeit more work to setup now. Examples below would be CNAMES based on client location.
- public ex1. www.useast1.aws.prod.example.com
- public ex2. www.uswest1.aws.prod.example.com
- by using the above examples of FQDN's is that giving too much information away, with regards to security. Should there be some obfuscation in the names.

Currently, we dont have a need for this complex of a setup, but is it worth the trade off of pre-creating this structure reduce future growth.

Any CircleCI experts able to help me? I can't access my context/environmental vars in my docker image (aws-ecr/build-and-push orb)

Hey all, as the title suggests I am trying to build & push a docker image to AWS ECR. Everything works good until the containers try and run! My app is dependent on the ENV vars, which are coming in as undefined.

Couple of notes:

1. I have no problem when I declare export environmental vars locally and test.
2. I have added the environmental vars to the CircleCI context and referenced that context (this works for other processes without problem.
3. I can see the step in CircleCI where the env vars are prepared.
4. Problem is, when I build & run, the containers are not able to access the vars. I have confirmed this with cloudwatch logs on the containers.

Here is the relevant line in my config.yml:

version: 2.1
- aws-ecr/build-and-push-image:
context: CIRCLE
requires:
- Build react app
account-url: AWSECRACCOUNTURL
aws-access-key-id: AWSACCESSKEYID
aws-secret-access-key: AWSSECRETACCESSKEY
create-repo: true
path: ./server
region: AWSREGION
repo: my-socket-app-repo
tag: "latest"

Any help is greatly appreciated! Thanks

Is there a service to handl rewriting URLs?

Hi all.

We are trying to reduce some technical debt/remove legacy applications in our ecosystem.

We've come across a simple .NET core app that a previous employee called "Domain Forwarder".

It essentially has a JSON list of hostname/hostname+path redirects and simply 301's.

For example, we have a bunch of legacy domains that have been setup with a rule to send them to a page on our website depending on what domain they are going to. If you go to abc123.com, you might 301 to ourwebsite.com/abc123.

This is setup in Azure on App Services and has all our legacy domains binded to it.

Is there a better tool/service that can handle all this for us? We want to reduce as many apps as possible so would be good if we had a service (preferably within Azure) that can handle forwarding of these domains/paths for us.

Thanks

I’m a software engineer that had to learn ops. I am not always sure how to set thinks properly. Any course / tutorial to follow?

Recently, my position made me implement the whole project architecture on AWS (with Terraform).

We are mostly deploying code on Lambda, but we also need to deploy some apps on EC2 instances.

I have successfully deployed an ALB with a single EC2 using docker swarm and Traefik.

However, I never managed to do zero downtime deployment with it. I had to develop a custom bash script to do blue / green deployment. (The script find the next color, deploy it, check the health of the app, switch the Traefik config to redirect traffic to the new color, check that everything is working, shutdown the previous color)

I’m using docker swarm mainly because it’s easier to deploy services, and I’m only deploying a single node app, with a single elastic search and 2 nodes of Traefik.

I feel like I’m doing something wrong, but I cannot point my finger at it.

Docker Swarm tutorial are quitte old, as I feel the majority of people are using Kubernetes.

Any help, tutorial would be awesome! I’m more than happy to share my scripts / terraform config

How do you keep on top of calendar tasks such as renewing certificates?

How does your team manage calendar related tasks such as renewing certificate, app provisioning profiles etc?

We use Confluence for documentation but I don't think there's a calendar plugin with reminders.

We are thinking of using Outlook.

Wondering if anyone has any better way of managing these things?

How Can I Keep the Storage Bill Cheap

Hello Reddit!

I have a project that uses about 16TB of bandwidth per month from users downloading files. I would like to keep quick download speeds, but the site does not make enough money to use any big-name brand providers.

Digital Ocean Spaces starts at $5 a month, but with 16TB, it's closer to $300 a month.

Does anyone know any cheaper alternatives or have advice for lowering the bill?

Favorite way to provision and configure ec2 instances?

Hey people,

&#x200B;

I'm looking to deploy some applications in ec2. The applications need to be configured with environment variables and require docker. I'm trying to think what are some of the quickest and easiest ways to provision new ec2 instances, and manage their configuration as a one-off and ephemeral instance?



I'd ideally like to use one tool for the provisioning and configuration, and would like to avoid needing to build out a CD pipeline. What tools are you guys using for provisioning and configuration? Ansible, AWS CDK, terraform?

Python or Batch script

Hello everyone. I recently got assigned with refactoring some batch scripts.

It included multiple logical part that could be seperated. Downloading dependencies, configuring downloaded dependencies and running some tests. The script was a little bit bloated so i moved dependency managment to maven, and wrote a python script so it would be easier to maintain. But %50 percent of the python script is just calling subprocesses to run tests and copying files.

Im kinda on my own. Company dont care how i do it and they are generally new to best practices to devops.

Most useful part of the python script is the -h option generated by argparse module. And i also made the script independent from the working directory (it takes command line parameters for directories it works on and has good default values)

Am i right to rewrite batch into python in this situation? Batch script was seperated into 7 files totaling at 300ish lines. Python script is 100ish lines

New to IT, should I consider a career in DevOps?

I'm a 26 yo guy, security studies major (geopolitics, military, international relations, internal security, etc. had some IT stuff but not much), just finished my master's degree and I have some decent job prospects in the local government administration or the law enforcement, but my programmer friend (5 years as a full stack developer, Java pro) said I should consider a career in DevOps (he explained to me what that is and after some digging it sounded interesting) considering my skills

so, my skills include:

• I'm a 7 year Linux user, 3 years Arch Linux, I'm not a sysadmin but I know the basics, like managing services, making my own services, managing accounts and permissions, ssh, making simple bash scripts (for selecting audio sinks and utility stuff like that), htop, ps - e, grep on daily basis, I basically love Linux, especially when it breaks, so I can spend countless hours fixing it in vim, when not using browser I tend to spend time mostly in CLI-apps as it feels romantic, neomutt for mail, cli Spotify client, weechat for IRC, etc.

• so Arch has this user package repository called AUR, I maintained few packages there, that's how I picked up git, pulling, pushing, commits, felt simple,

• I learnt a bit of MySQL, I can set up a new database, operate on data, SELECTs, JOINs, etc., we had a database class, that's where I picked up most of it,

• we were also taught how SSL works, so I know how to create a local certification centre, self-sign my website certificate and use it, learnt on apache, it was pretty cool, obviously the browser won't accept it, but still,

• what was also fun, we were taught how to create a private VPN? between two computers, ipsec racoon tunneling, had to generate asymmetric RSA key pairs,

• I installed OpenWRT firmware on my tp-link router, so it would have SSH capabilities, so I can now SSH to my router from my phone, make router send a magic packet to my PC to turn it on and SSH to my PC if I need something,

• I picked up a bit of Java for fun, liked the concept of object programming, I could create simple CLI apps like phone book or polling app on my own, but I gotta say that when I encounter a Python code (happens often when I use some amateur Linux apps) it feels way more readable,

• my friend sent me some simple project which I had to run with docker-compose up, I was amazed at the technology, frontend website, database and main backend program all on three different containers, I could SSH into each of them as all of them had separate internal IPs and different ports, the technology is neat, fascinating stuff, three separate but interconnected Linux installs!

So I'm not sure if this is stuff every IT graduate does like it's nothing or do I hold some promise? I never worked in IT, so it's okay if I don't fit in, it's more of a hobby for me. Cheers to you all, especially those who contribute to open source stuff!
