see if it is feasible and viable. Does the concept have market acceptance and potential?
* **Prioritize your features**. You do not want to simplify the software to the point where one of its core features is removed. The secret to creating MVP is to concentrate on a few important features. Prioritizing helps to point out all the elements you might want to have in your app. Basic features should not be sacrificed. Do not expand the limited scope of the product in the development process. Consider the user’s point of view, not only the developer’s or product manager’s.
* **Build an MVP and release**. Even though building an MVP does not fully represent the final version of a product, you should still maintain high quality in design, content, and user experience. The scope is limited, but the quality is not. The product must serve a target audience, focus at least on one problem, and be functional, usable, and comfortable. Create and release quickly.
* **Monitor the comments.** Seek feedback. Ask users to review the product. Incorporate user feedback into the development process to ensure the upgraded version meets the requirements. The purpose is not to obtain positive reviews, but to avoid bias and establish objectivity in gathering and analyzing them. Learn how to qualify feedback so that it benefits the company rather than harms it.

Based on the thorough market analysis and feedback obtained after creating an MVP, you can finally deliver the completed software to the market.

What is the proper method for implementing an MVP?

### How to Build a MVP Project Successfully?

**Keep track of your competitors**

Identifying the existing solutions helps to avoid pitfalls and flaws in what you are offering. How will your product assist your customers? Conducting competitive research before you build an MVP allows you to leverage the work of competitors as a foundation and learn more about what is not yet presented on the market. It is a starting point for deciding which market trends and opportunities to prioritize.

**Identify the ideal customer**

Who is more likely to be interested in your product? Each user group has its own preferences and requirements. Focus on a smaller number of people, since it is simpler and cheaper to reach them than if you were working for everyone on the market. Before deciding to develop an MVP model, do research. A market segmentation method eliminates irrelevant audience groups by using demographic, geographic, and behavioral factors like age, gender, occupation, region, purchase patterns, and others to obtain the data you need to better understand your possible target audience.

**Perform research**

Get an understanding of the problem and its solution. Answer the following questions: What is your market? Who is your audience? Which exact problem is your product meant to solve? What existing solutions does your competitor offer? Make a list of functions you want the product to have. Prioritize everything by categorizing them as must-haves, could-haves, and will-not-haves. Define success criteria for the [**MVP development process**](https://qarea.com/services/mvp-development) to evaluate desired results. Decide on the form of MVP you will be working with. One-feature or Product-mockup MVP?The best way to approach the project is to always begin with a minimum viable product that has just enough functionality to verify the concept without investing a lot of resources upfront. Always create an MVP to be ahead of the curve and prove the idea is working well.

I've come to the end of the DevOps road(map) - my mojo has gone.

I've been working in devops for quite a while and I don't think I find it rewarding anymore. It's not the technology stacks, I've always enjoyed being on the cutting edge of change, getting different things working together its more the mindset in the use or management of devops.

I dunno, I haven't enjoyed my last two jobs because of the internal politicing, the poor management, the lack of objectives and lack of direction.

Thing is I need a job because of family and cost of living etc, but I'm not sure I want to do devops work anymore.

I think I've become burnt out and disillusioned and I'm just venting as I decide my next steps

I've been thinking about doing independent consulting on the side for a while (and eventually maybe go into it full-time). But the challenge is I already get paid pretty well, so I don't know what I'd charge for my time to a client. What's the typical going rate?

Does any one know how to add XML transformation and variable substitution in Github Actions for Azure Deployment?

Essentially my company are moving our deployments away from Azure DevOps to GH Actions (as we are fully switching over to AWS in the coming months) - However I still need to put together a pipeline that imitates the Azure App Service deploy job we have in DevOps.

The Issue I'm having is that the xml transformation + variable substitution part of the job is super important (for using the correct connection strings based on deployment environment for instance), but there doesn't seem to be any documentation about how to add this onto the "azure/webapps-deploy@v2" action I'm using.

Below is the deployment part of my pipeline, any help on this would be appreciated!

- name: Log in with Azure
uses: azure/login@v1
with:
creds: '${{ secrets.AZURECREDENTIALS }}'

- name: Deploy to staging # deploys to staging
id: deploy-to-staging
uses: azure/webapps-deploy@v2
with:
app-name: WebApp
slot-name: staging
package: ${{ env.RUNNERTEMP }}/WebAppContent.zip

Job advice

After trying for more than a year trying to get into software dev position. I've largely given up in favor of a military application as a sysadmin.

I'm hoping this can be transitioned into some kind of dev-ops foot in the door, or is this widely unrealistic?

manage old dockerhub images

How do you keep track and solve the problem of old dockerhub images ? my own images are updated and rebuilt every day. no problems here. But i just noticed that i am using old images from dockerhub ( one of them is 5 years old :) ).

i was considering valid options arround this :

1. create a dockerfile using "FROM dockerhub/image" and adding apt-get update & upgrade. set the cicd and then using this image instead of dockerhub's
2. find a fork and use it
3. find a concurent project and migrate my config and use it
4. develop it my way

Deploying to multiple environments using Gitlab-Terraform

So I am currently making the transition from cloud formation to gitlab-terraform and I'm trying to wrap my head around trunk based deployment. We've done branch-per-environment in the past and have seen the pitfalls of that, so I am trying to see if this is a better solution.

A few hurdles we have is that we have three environments: Dev, Test, and Prod. And we have two gitlab servers. One responsible for deploying to Dev and the other is responsible for deploying to Test and Prod. It's a requirement for security purposes that I don't really want to get into, but syncing code between servers isn't the issue I am having.

I am confused on using one branch to deploy to multiple environments. I currently have the standard gitlab ci-yml working and we also pull in auto.tfvars file during the setup phase to control environment specific values. On the success of a development merge, we sync the code to the 2nd gitlab server, so that it can be used in the test / prod environment.

I guess my question is how am I supposed to handle deploying to test and prod with a single MR? I could definitely do it sequentially, where I run through my stages [setup, validate, plan, deploy\] again and swap out the environment variable so that the correct tfvars comes. But that seems clunky / wrong?

What is the cleanest way of doing this? Am I supposed to have a pipeline that goes sequentially? Or is there a slicker way of doing test / prod in parallel where I have two plans at the same time representing both environments that can be manually deployed? I feel like I am missing something here and haven't really been able to find a full solution yet.

How to manage and release features to different customers in both SaaS and self-hosted environments

Many organisations struggle with how to maintain a single repository and master branch to continuously deliver their software to their customers who require different features.

Some customers use online SaaS services, but some customers need to deploy in a private and self-hosted environment. You're struggling with how to keep the same released version.

If a new feature is only built for one particular customer at the beginning, you're struggling with how to canary ship a new feature to that particular customer and keep the same code for all the other customers.

You also struggle with how to respond quickly to customer requirements without involving too many engineers. If a customer success team can do that without engineers, that's perfect.

How to mitigate the situation?

Feature Flags Management Service is the must-have technology to solve these scenarios. Feature Flags is a modern engineering technology that decouples code deployments from feature releases, giving you control over who sees each feature and when they see it.

Feature Flags can be categorized into four pillars (Release Flag, Experimentation Flag, Operational Flag, and Permission Flag) in its lifecycle through development to customer success.

Operational flags and permission flags can be used to manage entitlements in software, which refers to controlling what features or functionality a user has access to based on their subscription or payment plan.

Release flags and experiment flags can help you to deliver a feature to a specific customer with minimal risk. It allows teams to test new features in production and progressively (percentage rollout) release the new feature to targeted customers to reduce the "blast radius".


I wrote an article of how to use feature flags to manage and release features to different customers in both SaaS and self-hosted environments. I hope this can help and get feedbacks.

📢 DEPRECATION ALERT: Mar 20 traffic from the old Kubernetes registry k8s.gcr.io will be redirected to registry.k8s.io

📢ICYMI this Monday, Mar 20, traffic from the older k8s.gcr.io Kubernetes registry will be redirected to registry.k8s.io


If you run in a restricted environment and apply strict domain name or IP address access policies limited to k8s.gcr.io, the image pulls will not function after k8s.gcr.io starts redirecting to the new registry.


How can you know if you're affected? it only takes a single line kubectl command to find images from the old registry! (see on the below post)


The deprecated k8s.gcr.io registry will be phased out at some point. Please update your manifests as soon as possible to point to registry.k8s.io.


This is actually good news, as the new Kubernetes community image registry registry.k8s.io will save major egress traffic costs for users not running on Google cloud ☁️

Question About Linking Repository To CI/CD

So I have a user account on the company Gitlab server.

When I want to link a repository to the company CI/CD tool by adding a custom private SSH key to CI/CD, am I adding the private SSH key that is linked to the public key of my own user account in Gitlab?

Am I correct in assuming this can't be right as everytime the CI/CD tool uses that REPO, it will have to pull the repo from my own Gitlab user account?

If this is the incorrect way to do it, what is the correct way to do it?

Test data for performance testing

There's some overlap here with data engineering and QA, but I'm more looking for information about how this problem is addressed in other companies and the role of devops/platform in it.

We badly need performance tests. Our service is used by hundreds of thousands of people all around the world. It has fallen over more times than I care to admit and I'm still a bit gobsmacked that we don't have any.

A sticking point we have is that the data in our non-production env where we would do these tests does not have anything like the same volume of production. We have many production RDS databases running on our platform. Our dot on the horizon is for the data from all these DBs to be ingested into a data warehouse where it can then be forwarded to multiple different endpoints. One of those would be the DBs on a non-production environment with a masking layer in between to scramble any sensitive columns. I'm glad we're agreed on the plan, but it feels quite ambitious and the data team who are building this aren't going to have it ready for a long time.

In the meantime, we need something a bit more straightforward. My first thought is to generate dummy data with a similar volume as production. It wouldn't be as good as data sourced from production but it would still allow us to get some value out of performance tests. Creating it looks to me like something that would be driven by developers and QAs, but I have little experience of doing it myself so I'm not sure how feasible it really is.

Can anyone share anything about how they've seen this problem tackled? Also setting up performance tests seems to be a task that involves different expertise working together (dev, platform, QA, data etc), so I'm curious about the different responsibilities that each role typically takes on. Thanks.
