Minikube and Kubectl explained for Beginners

In the [1st video "Minikube and Kubectl"](https://youtu.be/E2pP1MOfo3g) I cover the **theory** from:

* What is Minikube?
* What is Kubectl?

To **practice**:

* Setup of a minikube cluster locally

The [2nd video "Basic commands of Kubectl"](https://youtu.be/azuwXALfyRg) is basically a demo, where I'll go through basic commands by showing how to:

* create, edit, delete a pod
* useful debugging commands - e.g. how to get interactive terminal of the container
* apply configuration file

Please check it out and I hope these videos are helpful for some of you. 🤓

Confused about a core concept - what am I missing?

Docker allows applications & their dependencies to be bundled up so that they run predictably and reliably in any environment. Sure.

What if the app is a web app? Since the app runs in the browser, the underlying OS/local env doesn't _really_ matter, thus what's the benefit of docker here? In this case, I feel like the browser is the environment, is that right?

Or is the server it's hosted on still the environment?

Clearly, I have no true understanding of docker and I'm clearly missing something, but really want to understand. My question probably makes no sense, but if anybody could help fill my knowledge gap I would be extremely grateful.

Is testing part of a build process, or should they be seen as completely separate steps?

Disclaimer: All binaries should be fully tested before letting them touch production side. Period. This is something is fully believe in and won't deviate from.

There's basically 2 views on this:

1\. **Yes, the testing is part of the build.**

When you push something to your branch, this branch should be build and tested fully. This means the developer will have to wait for the entire process(includes unit testing and integration testing) to complete. The mindset here is that an untested binary is not a valid output and should not exist.

2\. **No, the testing is a separate**

Same thing as above, but if you push something to a branch ci/cd picks up your new changes and builds your code. This binary/output is then stored somewhere as an untested blob. *Then depending on your configuration*[1], you can run another job to test the output. This test job then does whatever the other method of working does and stores/deploys the tested output.

-----------------
My opinion:

Personally I'm in the mindset of the latter because it decouples the build from the testing, giving you the benefit of [1]. Not every branch needs to be tested on every push. I want to push and get results asap. I don't want to wait. The former mindset makes no sense to me since it just sounds like "tests are mandatory so every build should be tested", but that doesn't mean you should implement it on a technical level like that.

I'm curious about opinions from this sub.

Is a devops job a good move for me?

I am looking for new jobs and I am currently fullstack developer (technically lead architect) for the startup I work at. I do a lot of devops in my current role and am about to sit the AWS CSAA exam and I do enjoy this aspect of my work. I am interviewing for a Head of Devops role at a challenger bank which I think I have a good shot at but this would likely not include any application development.

I would like my future roles to be things like Head/VP of Engineering do you think this is a good career move?

Is there a way to hit a particular pod for a request.

So i have a kube cluster deployed for a service which runs around 50 pods. A few of them having been going out of memory and I am pretty sure there is memory leak in my application. I have written an endpoint in my application which takes the heap dump and then uploads it on s3. I want to take this heap dump on a long running pod so i can debug the mem leak. Is there way i can hit a particular pod using postman by passing in some selectors?

[DevSecOps] Stick to CentOS 7.x for DevSec Linux Baseline or attempt to adapt it to CentOS 8.x?

I'm using https://github.com/dev-sec/linux-baseline to create hardened image basic templates. However, the repo hasn't been updated to support the newer distributions yet, and I need to stick to CentOS for a specific project.

In terms of best practices, should I stick to CentOS 7.x as a known safe default, or or try to lift up the DevSec Linux Baseline to support CentOS 8.x instead, without really knowing what I'm doing?

Build a Serverless appliance with cloud-init and faasd

Have you heard of faasd, [the new provider](https://docs.openfaas.com/architecture/faas-provider/) for OpenFaaS? It's just like OpenFaaS on Kubernetes, the same API, same UI, CLI and ecosystem, but without the complexity and stress of running a scale-out distributed system.

In this short tutorial I'll show you how to leverage cloud-init, a standard way to install packages and to configure cloud hosts to get a faasd host in less than 5 minutes flat. Or your money back.

[https://blog.alexellis.io/deploy-serverless-faasd-with-cloud-init/](https://blog.alexellis.io/deploy-serverless-faasd-with-cloud-init/)

If you're avoiding Kubernetes, or keen to use the right tool for the right job, would you use this? What would you like to see in terms of documentation and literature around it? If you try out the tutorial, please let me know what you think.

VPN *INTO* China

Hi guys,

I just received a very... unusual requests from one of my clients.

He's located in EU and needs a possibility to connect to an FTP server located in China.

Of course, port 21/22 is blocked from outside of China and of course a special whitelisting rule cannot be added.

Because... why would it be so simple?

So my question is: Do any of you know of some sort of VPN/Proxy/server in a basement that I can use in order to "get into China"?

Thanks...

Looking for recommendations on a Orchestration tool for my specific use case

I wish to orchestrate the following

Terraform plan/apply to AWS
Packer build for AMI’s
Ansible for configuration within the client OS

It is for a new project, I already have good knowledge of the above but need to bring in an orchestration layer above, as currently ops are pushing manually to AWS

Goals
Changes are made within a Git repo by a ops engineer and are put through several automated steps to validate and obtain approval prior to deploy
LDAP integration
UI to be view deployments
Secure
Highly Available
Easy to manage (Team is made up of mainly infrastructure folks, not developers)

I was leaning towards Jenkins but not sure if its over kill for our requirements - we don’t develop applications only automate the deployment of infrastructure and deployment of instances etc

I appreciate any advise you are able to offer

Is Packer still the best choice for building images for multiple clouds?

We need to run custom images on a number of clouds and currently this is mostly done through bash scripts and the like. I was looking into using Packer to consolidate all this under one tool, is it a good choice? Any competing tools that show promise?

Deploying using a batch to multiple machines, what tools will help me?

So right now I'm working with a legacy system, I know a big surprise, and our system is distributed across multiple machines that are identical. For example we have 4 servers of type x, 4 servers of type y, and 4 servers of type z all which work to run our application, each of these servers uses a batch file that pulls down some code from a repo and builds out the repo it pulled down.

Now what I want to know is what type of tools I can use to make our deployments faster, centralized, and to avoid as much human error as possible, currently our deployment requires logging onto each machine and running the batch file which is laboring , not to mention very prone to human error. I imagine I could write some scripts to call out to each machine and have it run all my batch file as long as it is in a common path across machines but this loses me a few things and overall just really doesn't seem like a good solution I could go further into why but I think we understand. My next thought was to use something like octopus and have that installed on each machine and then using a process within Octopus to trigger the batch on each machine and in that way I could avoid human error, have a centralized tool that I have some experience with in the past.

While I believe Octopus solves the issue I'm working on I'm curious of any other ideas for how I could approach this problem. Any and all suggestions / criticism about my current solutions are appreciated.
