Just wondering, career question(s).

Hey everyone, to cut straight to the point: I’m 25 years old and currently in IT support (entry level). My goal is to eventually become an infrastructure engineer / SRE.

How long would you say it would take someone to get from an entry level support job to at least a Junior Infrastructure Engineer?

How much would you say I could accomplish in five years time? I know this is super subjective, but yeah.

Every time I scroll this sub I always see comments full of people talking about the intricacies of all these technologies etc, like how did some of you even get to that point?

Github actions - How to compile .scss files to .css files?

Hey all,

When I try to compile it, I am receiving this error in github actions:

Error: /src/scss/main.scss: no such file or directory

}

Here is my main.yml, I am following[Sass Build Action](https://github.com/marketplace/actions/sass-build#quick-start) as the template to convert .scss to. css.

build:
runs-on: ubuntu-latest
steps:
- name: Compile CSS from SCSS files
uses: gha-utilities/[email protected]
with:
source: /src/scss/main.scss
destination: /src/scss/main.css

#deploys to heroku
- uses: actions/checkout@v2
- uses: akhileshns/[email protected] # This is the action
with:
heroku_api_key: ${{secrets.HEROKU_API_KEY}}
heroku_app_name: "ga" #Must be unique in Heroku
heroku_email: "[email protected]"
- name: Compile CSS from SCSS files
uses: gha-utilities/[email protected]
with:
source: /src/scss/main.scss
destination: /src/scss/main.css

Here is my project directory

.github
-> workflows
-> main.yml
src
scss
-> main.scss
-> main.css (untracked in git, and is used locally)
package.json

From my understanding, main.yml starts with the directory level of package.json. Thus, why is it giving out the error?

Connecting Terraform to Terragrunt

This is a tutorial on how to keep your Terraform modules DRY.

Often companies end up with enormous replications of the same resources in different folders.

GitLab Runner Infrastructure

What approach do you guys use for hosting GitLab runners?

I’m building out test automation infrastructure. I have the test runner in a docker image. Mostly web based GUI and API testing, with quite a bit of GUI testing that takes a while to run. (I know API>GUI testing but I work on large project with large distributed team, I can’t control everything)

I have a static EC2 image that handles jobs sent from the test pipeline. The tests run in parallel in a number of separate containers.

I’m fairly new to DevOps and not sure how to scale this up. My boss suggested a kubernetes cluster which from the sounds of it can do all that and a lot more. I’ve seen ECS and autoscaling EC2 groups in my research as other possible approaches. Any guidance or words of wisdom for a novice?

Looking for a calendar web app prederably hosted in docker to add events and send reminders to some emails list before the events

Hey all. I'm looking for some simple web application to add some events (downtime and similar) with some date, time, details which will then send us some reminders X hours prior to the event. Preferably I would like to host this app in some docker container. Bonus part is to be able to subscribe to the calendar through Outlook for example to show the events with the normal calendar.

Any suggestions? Thanks.

Azure or AWS?

I am a system engineer with no cloud experience and when I browse job boards most all are looking for cloud experience. Which cloud infrastructure should I most focus on learning? I'm sure the concepts carry over but I want to focus on the one which will make me the most marketable.

Equivalent of Consul/Consul-Template in AWS for real-time configuration management?

New to cloud esp. to AWS. Unfortunately I could not find anything that I could use in AWS in-place of consul-templates that I am used to when working on-prem. Basically, right now we are having to manually change config files and update them again and again which is very annoying and cumbersome. What is the standard for this on AWS?

Individual dev environment?

I'm currently working at a company where each developer has their own designated environment in AWS. Curious if anyone else out there uses a similar model. And, if so, very curious how much you all are spending per dev environment?

Why DevOps is paying so much?

Curious question, DevOps seems to be bombing and payscales seem to be at the top.

I am college dropout working as SRE and compared my salary to a data scientist with a master and I am earning a little above him when we discussed openly about salary.

I think like cheating because I believe the learning curve for being a data scientist is higher than someone who does SRE. Is this a bubble? Will it explode someday?

Pulling/Pushing out any AWS ECR images from/to AWS ECR through AWS Route53 CNAME

The main idea of this article is to show how to use CNAME of Route53 to pull or/and push images from/to AWS ECR service. By default, Amazon doesn’t allow to do it (SSL handshake is not working. SSL has been signed by Amazon side).

I played around with Amazon API and Python and proxy and I have found several solutions:

* Use Python and develop wrapper to log in, pull & push AWS ECR images from/to ECR through AWS Route53 CNAME of AWS ECS service.
* Use Some proxy (Ex: Nginx, Traefik, etc) and make forwarding rules with needed headers. This implementation is \`TBD\` soon!
* Amazon ECR interface VPC endpoints (AWS PrivateLink).

The full article you can read here: [https://medium.com/@solo.metalisebastian/pulling-pushing-out-any-aws-ecr-images-from-to-aws-ecr-through-aws-route53-cname-7c92307f9c25](https://medium.com/@solo.metalisebastian/pulling-pushing-out-any-aws-ecr-images-from-to-aws-ecr-through-aws-route53-cname-7c92307f9c25)

Is docker swarm good enough for production?

I'm getting into docker swarm lately. Everything I've done with it I've done locally of in a test environment.

Especially looking for someone well versed in docker. I've heard swarm is great for dev environments but not for production. Is this true? And if it is why is it not good for production environments?

I haven't seen any issues so far but like I said I've never even considered using it for production until now.

Why is the Interview Process a pain in the ass?

Interviewing for my second title within the DevOps/SRE space.

Why the hell do so many companies have a multiple-hour interview or technical task as a part of the interview process?

I understand that they want to ensure that the person they're hiring understands what they're doing, but I simply cannot schedule a 2, 3, or even 4 hour block (all numbers that have been estimated to me) out of my free or working time to further myself along in the interview process. What happened to references, or simple 1-hour technical interviews?

So far, I've declined further candidacy for 3 jobs, and I'm sure that number will grow.

Anyone else commonly experience this mess? How do you handle it? Am I being ridiculous?

How to learn high level devops concepts as a dev ?

Hi guys,

I'm a full stack dev but I must say my understanding of many devops concepts are very poor, I can get around by following some tutorials and using dev friendly solutions but it comes with limitation, sometimes vendor locking and I don't really like using GUIs as in my experience they cause more problems than they solve and I rarely use those since I mostly live in the shell anyway.

I believe even a higher level understanding can help troubleshoot some problems so I'm looking forward to better understand concepts like, reverse proxies, CDN, load balancing, understand docker better etc.

Thanks in advance.

Can readfromhead work with posfile together?

Set posfile only will send data correctly. But if set with readfromhead will get error

<source>
  @type forward
  port 24224
  pos_file /a/pos_file/path
  read_from_head true
</source>

Because of readfromhead, fluentd can't start successfully.

If set readfromhead only, fluentd can start but can't send data.

Can't they work together?

Has anyone considered moving from DevOps to just Dev?

A bit of background:

I switched careers 2 years from non-tech to DevOps and I’m now in my 3rd role and have been in it for 8 months. It’s a Senior role and pays pretty well but I’m not really involved in actual dev work, neither in my DevOps chapter nor the dev squad in which I sit.

The thing is, I really enjoy writing and contributing to application software but don’t have loads of experience in doing so. I’ve done some Python application work in a previous role and I’m currently learning Java in my spare time.

Anyone else been in a similar position? Would love to know how you approached it!

Running AWS Services In A Laptop Using LocalStack

LocalStack is a fully functional mock of AWS services running locally on your computer. We can use it to develop and test cloud and serverless apps offline. It can run through the CLI, in a Docker container, or in a Kubernetes cluster. We can use it to create mocks of S3 buckets, Lambda functions, RDS databases, ECR repositories, and more.

I got an opportunity to become a DevOps but I'm scared to go for it

Hope it's okay to discuss career direction here.

A little about me:

* 26 y/o
* 4 years in IT (3 as helpdesk, 1 in current role at a FAANG company)
* Almost no DevOps knowledge

**I know**: Python, PowerShell, some git, some Ansible, I'm OK at Linux, I know networking concepts and fundamentals, I'm comfortable at troubleshooting and I like documenting stuff.

**Weak points**: Storages, not fully comfortable with Ansible, don't fully understand a lot of Dev subjects like different APIs, webhooks and in general, anything I listed under "I know:", I'm still no expert at those things.

**Zero hands on knowledge (I know the concept)**: K8s, CI CD tools, IaC tools like Terraform, etc.

Another thing I wanted to mention is my learning process. Sometimes I feel like it takes me longer than average to get something. I'm actually lacking confidence in general at my field, but overall, I'd say I do a good work as a Sysadmin.

One of my former colleagues (from my current role) offered me to join the company he works at. My role would be DevOps even though he knows I have zero experience. He mentioned that he saw potential in my skills and that he'd help me develop whatever skills needed for this role.

Honestly I'm a bit confused as to whether I should go for it. Salary isn't a factor currently because I'm more focused on gaining experience. The location is the same as well, which is nice.

It's a startup, as opposed to my current FAANG company, which is a bureaucratic mess sometimes.

I'm afraid to disappoint my former colleague. We worked together for like 6 months and during that time he was somewhat of a mentor for me. I'm not sure if I'm ready for this role but I know it's a good place to take my career to at my age.

What do you guys think? What other factors should I consider before talking to him about whether I'm in or not. I'm only 11 months in to my current role and I'm worried my tenure is too short.

Thanks :)

Vault and 1Password for different cases

Does anybody uses vault and 1Password together? I feel like they solve different things. Vault is really for managing secrets for automation while 1Password is for a team or person to manage their passwords.

Sure, vault can be used for passwords but it’s a bit technical and not everyone on the team wants a cli based tool when they want to login somewhere.
