SWE or Observability?

Hi everyone, I’m looking to gain a little bit of insight from those who are more experience than me. This week I’ve received two internship offers from medium-sized companies, an SWE internship, and an Observability internship, for a few months. I’m currently not sure what’s the best option, what are your thoughts? Which one is more beneficial long term when looking into applying at larger companies?

Also, just to clarify, is Observability the same as DevOps? A different branch from DevOps? Does Observability include the same amount of coding an SWE would? I’m quite new to Observability, so any insight is appreciated.

Mono-repo vs. multi-repo

I know that there is a debate about storing all source code in a mono-repo vs multiple repos.

I am thinking about it from a security perspective:

A separation to multiple repos reduces the risk of source code exposure/leakage.
More granular access control can be applied on distinct repos.

However, maybe this isn't a high risk as having an insider threat or an account takeover that may inject a malicious code, so setting up codeowners will do the work even in a mono-repo.

What are your thoughts?

Controlling GitHub Organization Repository Creation

Hi All,

For any of you that use or are a part of a GitHub Enterprise organization, how does your organization manage the creation of new repositories? Do you allow any member to create new ones, or do you have a process/control mechanism for their creation?

My organization has been exploring the idea of setting up a review process for the creation of new organization repositories (not forks or branches), but it doesn't seem like there's a straight forward way to do this aside from either only allowing the organization owner to create the repositories, or having a written policy without any technical controls.

Thanks in advance for your input.

Starting my first DevOps Engineer position

Coming from the classic corporate IT world working as a Sys Admin, I‘ll enter the world of DevOps in February.

My programming skills are subpar to be bluntly honest and I have no idea how developers work.
I‘m also a little nervous since it‘s a complete switch from a Windows environment to Linux and Apple only.

It‘s a local web development agency and the technologies used in DevOps are Docker, Kubernetes, nginx, Ansible (among other stuff like Python scripting).
I got access to a cloud hoster‘s page and already created an Ubuntu server to screw around with.
Also got some documentation for Linux basics and some of the mentioned technologies but trying to work through that stuff I feel like an idiot who doesn‘t understand anything.


Could anyone provide me with resources to study and/or do some exercises?
Mainly DNS in Linux and Docker would be helpful.


Thanks a lot and y‘all have wonderful holidays!

Linux Foundation 35% off certifications - is this a good chance or a repeated campaign?

I want to get the CKAD certification. Linux foundation currently (until 12am tonight) has a 35% sale. Is this really a special deal and a unique opportunity or is this a recurring thing and I can expect such a sale soon again?

AWS CodeDeploy multiple artifacts to same EC2 target.

I've encountered a problem with CodeDeploy pipeline that is driving me nuts. I'm new to AWS (come from Azure DevOps, where what I'm trying to do was trivially easy), so please bear with me.

In CodeDeploy, I'm trying to build a pipeline that deploys two artifacts from separate repositories to the same target EC2 machine.

In my pipeline, there are two source triggers from two separate CodeCommit repositories, one for each artifact I want to build. These triggers create two CodeBuild artifacts, each stored in S3.

Once the Deploy stage of the pipeline begins, the idea is to deploy both artifacts onto the same target server into two separate folders. For example, one artifact should be in "/home/user/artifact1", while the second would be in "/home/user/artifact2".

This "works"... it deploys the first artifact successfully to "/home/user/artifact1".

When it begins to deploy the second artifact, the first artifact is completely removed from the EC2 instance. "/home/user/artifact1" is now an empty folder. The pipeline then successfully deploys the second artifact. This leaves me with a successfully completed pipeline execution, but the final state of the EC2 instance has only the last artifact deployed.

I feel like I'm missing something simple... but coming from a heavy Azure background, learning AWS has just not been intuitive for me. Compared to deployment pipelines in Azure DevOps, the AWS CodeDeploy tool feels extremely limited. It seems like this should be trivial to do, so I'm obviously missing something... Any help would be great, because AWS documentation hasn't been very enlightening.

Thanks.

Automate git push with Ansible

Hi everyone,

I’m trying to automate deploys. I have two repositories. First I am cloning the repository (called DEV) to my PC, then push from my PC to the repository called PROD.

Here my first yaml, this way I am cloning the external repository (DEV) on my local PC

--- -
hosts: localhost
gather_facts: false
tasks:
- name: clone repo test
git: repo: https://github.com/test/test-repo.git
dest: /home/user/git-test/
clone: yes
update: yes

How do I push the repository located in */home/user/git-test* (local) to PROD repository using Ansible?

Any examples?

I created an Outlook add-in sample with python for the community

Hello everyone,

I just finished creating an Outlook apps addin template for python!

https://github.com/Masterjx9/Outlook-Addin-TaskPane-python

Its basically a modified version of the office addin taskpane JS repository from here: https://github.com/OfficeDev/Office-Addin-TaskPane-JS combined with a modified version of the azure webapp sample from here: https://github.com/Azure-Samples/python-docs-hello-world

Why is this good? - This allows you to use Python as the backend for your Outlook addin instead of using node.js. So you can use flask, and any other python modules with your outlook addin. Microsoft ONLY has examples from asp.net or node.js for there office addin samples, so I am hoping this will help others who want to make an addin for outlook or office in general but with using something like python.

6 DevOps Trends for 2022

Wrote my view of DevOps trends for 2022. Would be interested in opinions or suggestions what else you think is trending.

Here is my list:

1. SBOMs are Getting Traction
2. Race to Replace Docker is On
3. Cattle Clusters and Inter-Cluster Ingress
4. Wider Adoption of Blue-Green and Canary Deployments
5. Bridging the Gap Between Internal Platforms and Production
6. Establishing DevOps Baseline (This means focus on education as too much legacy technologies are mingled with what is considered best practices).

Which enterprise VPN do you use?

We have internal services hosted in AWS that our employees must access. Does anyone have a VPN service you recommend that can scale, and automate (things like user creation and initial setup)?

Currently we use OpenVPN AS, but we cannot continue using that for two reasons:
- It gets very expensive when you reach 100+ users.
- You cannot automate the deployment or creation of users.

I just wanted to say thank you. Thanks for being kind and supportive. Wishing you all Merry Christmas and Happy New Year.

As a programmer & DevOps engineer, I was committed to share my knowledge with community on DevOps, Docker, Kubernetes, Ansible, Cloud, Terraform, GitLab CI, Jenkins,Splunk, Prometheus and More!. Where I (We together) have reached now, I couldn't have done it with out your support.

When I started my YouTube journey didn't received much support, but it was my friends and you are in forefront of those who motivated me to kept going. I wanted to develop a set of free DevOps courses that will allow people with minimal coding experience, and take them step by step with clear plan to reach their goals. Whatever your background, as long as you are willing to put in the work you can find an entry into this field.This is completely free, there's no stealth upsell (really, there's nothing to sell, there's literally no way to pay me).

You gave me a safe place to be and encouraged my interests. Everyone went above and beyond to make sure I didn't fall through the cracks. And I wanted to let you know: I remember and you all will be in my heart. The work I did is not in vain.

You are loved, and appreciated, and make a literal lifetime of difference to a YouTuber like me. As I'm not a professional YouTuber, I'd love to hear your feedback and support

Thank you.

Admin: I just want to say thanks to all of the DevOps community.

CI for services that send email?

I have a service that must leverage SMTP (AWS SES or Office 365 APIs) to send invite codes to new members. So far it seems like this singular integration breaks any hope of E2E testing. Has anyone circumvented this, such as to implement CI?

CentOS 8 is dead :( Any recommendations for a free/Azure friendly alternative?

Just realized our CentOS 8 VM's are about to loose support. My small company doesn't use them for much, so we haven't kept a close eye on them.
Any recommendations? CentOS stream? I really love using Azure Update Management for our Windows VM's; so it it plays well with Azure that's a huge bonus.

Looking for a notifications tool for internal tools

Hello, I'm looking for a tool with specific purpose.

I'll try to explain the need first. My company is really big and consists of many groups so there are a lot of different tools that were developed. One group could be the customer of another group, by using their tool. This means that this group is interested in the release process of that tool (like release notes, urgent notes, etc).

I'm looking for a self-hosted and open-source tool that is a website where users can register their tools and other users can "subscribe" to notifications of the tools. For example, if the tool have a new version, the owners can send the release notes to all the users that are subscribed to the tool.

Also, if for example the system of the tool is down (or planned to be down), the owners can notify the subscribed users using the notifications. In addition, users can check the history of previous notifications. The users are intenal and we could configure them using the internal mailling list.

The tool should be self-hosted so we could run in a container on our cloud. Actually, I didn't came up with this idea, I already came across with such tool, but I could not find it online. Can someone suggest it?

How to create a hosting company using docker + kubernetes?

The hosting model for old sites and systems was with cpanel. And the best solution on the market for servers was CloudLinux. I'm looking for something for the private cloud model, a dashboard that I can offer hosting plans, vps and the like, using docker and kubernetes for high scalability.

​

Is there any panel that allows you to sell VPS or website hosting with kubernetes integration?

DevOps as tier 1 developer support

I've been with my current team for a few months now, and it's struck me as odd that DevOps is the first point of contact for developer requests, which is anything from restarting services, checking user permissions (merges/PRs/Pipelines) troubleshooting application stacks, project/process tweaking in Jira/ADO... you get the idea.

While these requests are generally DevOps related, I'd say a good 40% of them are more suited to IAM, senior developers, POs/PMs etc.

My question is - is this the expectation for a DevOps team? Experience tells me no, but maybe I've just been lucky up to this point.

P.S. I should add that while I don't mind supporting my colleagues, I know that our engineers are capable of doing so much more than responding to support requests
