Transfering Wordpress to k8s

Transfering wordpress site

Hello there, as I want to be prepared for the future I created my own K8s cluster for my business projects (sites or webapps for clients) but in the past I used just basic wordpress app.

Do u guys have any idea how to transform a already present wp site into a docker-container and deploying to kubernetes.

Thanks :)

Hands off, cloud based config management

Looking for something simple to handle basics - patching mostly. Want to have everything in IAC of some form.

This particular use case is for labbing with the most "production" aspect being Plex.

I've been looking at azure Automation but it seems a bit heavy handed.


On top I'm planning to run some other cicd product (devops agent, Argo, not sure yet) if there's maybe something open source that has both config management and deployment all in one?

It seems from my research that there's nothing quite simple and plug and play in the config management space yet.

Reproducible and portable development environment

Background: there are two machine, machine A has internet access while machine B does not, I can copy file from A to B

Machine B is for development purpose, so I need vim tmux git and some plugin include dot files on it; currently I use docker to build the image contains vim tmux and misc on machine A and copy to machine B for code development

And recently I heard about nix package management, so is it possible use nix to build development tools and port it to other machine?

I thought nix is somewhat more reproducible than docker, since docker image rely on the linux distributor, but I cannot find a way to make nix portable to offline machine

Broke AWS account during internship. How bad of a situation did a I put myself in?

So I broke one of the AWS account during my 3rd week at this internship at a very large company. Users are still able to log in but there’s some API errors when it comes to getting any type of resource in the account. That is due to my dumbass using an AdminPriviledge ARN in my IAM terraform script. So when I did terraform destroy I messed up the privileges for everyone who has access to the account.

For the experienced engineers, how bad is this? Is this something to fire an intern over?

I was one of the “senior” interns coming already with experience with terraform and other DevOps tools. Now I just fucked up so badly when I was banking on getting a return offer due to my financial situation.

What's your DevOps stack?

This is probably a broad question but curious as to what technologies people here use either in work or for personal projects for a full infrastructure to deployment or anything even in-between

At work we have started to migrate over to gitlab and leverage it's CICD tool and it's runners to deploy and run automated tests. We use quite a lot of Ansible for most of configuration and as well creation of our containers.

Some older pieces are still deployed with bash and salt stack. A large part of why I'm curious of how others do deployments is that we are hoping to move this over to AWX (Ansible tower) to help make our deployments HA and I'm curious how others handle this?

NOTE: we are not on kubernetes, nor is it a high priority to migrate, but still curious to hear If that is part of your stack and how it is!

What's the advantages (or main differences) of using Linux with AWS compared to using Windows Server with Azure today ? How many of you are well versed with Azure/Powershell ?

I need some advices from experts I am studying Windows Server with Active Directory on a virtual network with VM's and some Linux on the side... I live in a very remote place where there is no jobs for advanced sysadmin so I am thinking about going back to programming so I can do some WebDev being 100% remote but my main love is sysadmin... I can study 7-10hr's a day if I want and I wanted to be solid with both WinServer and Linux and was wondering if it was worth it to get the Azure Certs or go the Linux route with Aws ? Is it me or I feel like the good old day of sysadmin are starting to die off slowly and we are getting in automation/scripting a lot managing online services and pre configured iso's that pure sysadmin of system on premise is becoming less and less important or useful and everything is becoming infrastructure as code ? why not just go program then ?

A) What's the advantages (or main differences) of using Linux with AWS compared to using Windows Server with Azure today ? How many of you are well versed with Azure/Powershell ?

B) Do you feel that "on premise" is losing ground everyday to the Cloud ? We will need less and less Datacenter and we will be managing more Cloud services and automate everything ?

C) How long does it take to be solid Junior/Intermediate in both Windows Server and Linux with some Cloud ?

I already knows how to manage small AD, DC and all that file share, bit of Linux and already coded in C++ in the past so im not starting from 0 I can study all day most days for the next 2 years was wondering whats the best use of my time.. don't really feel like spending 2k on all the online official Azure Certs from MS

What is Continuous Delivery?



Technology is advancing at a breakneck speed, and customers expect to experience that from their service providers and products. In today’s fast-paced world, technology is advancing at a breakneck speed, and customers also expect the same speed from their service providers.

Continuous Delivery is a DevOps methodology that enables development teams to deploy changes such as new features, configuration, bug fixes, and experiments into production safely and quickly in a sustainable manner. The continuous delivery process requires a collaborative approach from different stakeholders in a software delivery process such as developers, operations, and testing teams. It streamlines the complexities of software delivery into a pipeline model that allows for a smooth flow of codes/changes from developers into the hands of end-users.

We refer to this pipeline as a DevOps CI/CD pipeline that allows organizations to deploy code changes to test and production environments through a repeatable and automated test release process empowering developers to release changes on demand.

Advice on helping pave the path for DevOps in IoT for a research scientist

Background: I have been working as a Research Scientist for an Institute focused on Industries and Production Engineering for about 4 years now. My educational background is ICT Engineering and enjoy programming. I am very active in Open-Source Communities and have a developed good skills in IoT and IIoT (shows through my published work as well as my software portfolio on GitHub).

I really am getting a good vibe about DevOps as a concept because it is enabling me to learn all tools that can make me independent in my development work i.e. My Code + My CI Pipelines + My complete loop of Operations.

AFAIK and understand, a lot of DevOps focuses on Web Tech, granted IoT is part of the Web but the paradigm itself uses a lot of different protocols that generally don't get deployed on machineries, sensor nodes, wireless gateways etc.

I am looking for some guidance on how does DevOps + IoT path would look like.

Skills I am good at:

- python, c++ (arduino), Yocto/OpenEmbedded, TSDBs (time-series DBs), Sound IoT Protocol (MQTT, CoAP, CBOR, etc.), git, docker, docker-compose, basic CI pipeline setups using Travis-CI, GH-Actions

- Currently learning: Rust, Kubernetes, golang
- Willing to learn: ansible, terraform, a Cloud Platform

But with a narrow focus on IoT and Operations in Industries.

Automation / Scripting

Hi everyone !

Does anybody knows the best way to build and provide a service that can be hosted on the cloud, receiving a file in IDML format from Adobe InDesign (via HTTP POST ideally, possibly FTP or other) able to provide in return the full PDF version with the most faithful rendering to that of InDesign, either via HTTP return or possibly deposit on FTP or cloud storage ?

I would be happy to exchange on the topic, as i encounter some troubles with it.
Thnks :)

Gamify Twitter with Prometheus and Grafana on Kubernetes

Hi everyone,

I personally have Gamified my Twitter banner with Prometheus, Grafana and some custom Python code on Kubernetes. I've made a write-up for inspiration: https://www.civo.com/learn/using-civo-kubernetes-to-gamify-twitter-with-prometheus-and-grafana

(And yes, It's more intended for FUN and just hacking around, rather than very serious business ;) )

What is a cool thing I can show high schoolers who learn programming that will be interesting to them?

Hey all,

I'm a DevOps engineer and I got this feeling that I want to go and volunteer somewhere.

I came up with the idea to go to my old high school and show them something DevOps-related that they might find interesting and if any of them want to, I could teach them a thing or two.

Now I'm trying to think what in our field would be interesting but simple enough that high schoolers could enjoy.

I could always just do a docker demo or IAC type of thing but I don't know if they'll find it interesting.

What are your thoughts?

Best monitoring tools for clouds?

I would like to know if you have used some monitoring tools and what are the best for cloud like Azure, AWS, GCP, etc. I would like to implement and monitoring my resources like the VMs, the networks, the infrastructure, the security, the applications, etc. in the different clouds. I have read that some goods are datadog, appdynamics, instana.

Which is better ?

Do you think it's more a enriching experience to work as a DevOps consultant and getting to work on a lot of different projects or as a DevOps engineer working on same company projects ?
