Docker Tutorial for Beginners: Learn Docker Step by Step

What is Docker?

Docker is an open-source platform that enables developers to automate the deployment of applications inside lightweight, portable containers. These containers include everything the application needs to run—code, runtime, system tools, libraries, and settings—so that it can work reliably in any environment.

Before Docker, developers faced the age-old problem: “It works on my machine!” Docker solves this by providing a consistent runtime environment across development, testing, and production.

Why Learn Docker?

Docker is used by organizations of all sizes to simplify software delivery and improve scalability. As more companies shift to microservices, cloud computing, and DevOps practices, Docker has become a must-have skill. Learning Docker helps you:

Package applications quickly and consistently

Deploy apps across different environments with confidence

Reduce system conflicts and configuration issues

Improve collaboration between development and operations teams

Work more effectively with modern cloud platforms like AWS, Azure, and GCP

Effortless Docker Mastery: The Ultimate Tutorial for Developers

Are you ready to delve into the world of Docker? Let's embark on this journey together with our Docker Tutorial.

First things first, what is Docker? Imagine it as a magic box where you can pack up your application along with all its dependencies. This box, called a container, can run anywhere! Isn't that amazing?

To start, you'll need to install Docker on your computer. Don't worry; it's a simple process. Once you have Docker installed, you can create your first container. Think of it as building your own virtual world for your application to live in.

Now, let's talk about Docker images. These are like blueprints for your containers. You can find ready-made images on Docker Hub or create your own.

Next up, Dockerfile. This is where the magic happens. With a Dockerfile, you can define exactly what goes into your Docker image.

Once everything is set up, it's time to run your container. Just a simple command and your application is up and running in its cozy little container.

But Docker is not just about running applications; it's also about managing them. You can start, stop, and even scale your containers with ease.

And that's just the tip of the iceberg! With Docker, the possibilities are endless.

So, are you excited to get started? Head over to our Docker Tutorial on TutorialAndExample.com to begin your journey into the world of Docker!

how to make cool blobby turing patterns in photoshop

i'll preface with i learned the basic loop from skimming a tutorial on youtube, but as someone who prefers written tutorials i'm sure many would appreciate one! also, the second part of this is some of the visual effects i figured out on my own using blending modes and stuff.

i'm using photoshop CS4 on a mac so some buttons and stuff might be in different places on windows and newer photoshop versions but all the actions are the same. my canvas is 1000x1000 pixels.

UPDATES (i'm hoping these'll show up whenever you open the readmore?)

it's possible to do something similar in krita using this plugin, made by the love @arcaedex

it's also possible to do this in photopea, a free browser alternative to photoshop! the results are pretty much identical.

FIRST off you wanna get or make a black and white image of some kind. it has to be one layer. can be noise, a photo, a bunch of lines, whatever. here's mine, just some quick airbrush lines:

now find the actions tab. idk what it looks like in newer versions of photoshop but you probably won't need to dig!

hit the little page thingy to make a new pattern. once you hit 'record', it'll record everything you do. the little square 'stop' icon will end it.

now you want to do a high pass filter. you can mess around with the radius to change the size of your squiggles, but the tutorial had it set to 6. experiment!

now add the 'threshold' adjustment layer. i use the adjustments tab but i think there's also a dropdown menu somewhere. keep it at the default, 128. merge it down. (control or command + E or you can right click it like some kind of weirdo)

and finally, the gaussian blur! the radius of this affects the shape and size of your squiggles as well. i like to keep it around 4.5 but you can mess around with that too.

after that, hit 'stop' on the action you're recording, and then repeat it a bunch of times using the 'play' button, until you have something you like, like this:

WOW!! that was fun!! and only a little tedious thanks to the power of macros. anyway, here's some fun layer blending stuff i like to do. it's with a different pattern cause i made this bit first.

anyway, using a black and white gradient (or a grey base that you do black and white airbrush on), make a layer with the vivid light. this will make the blobs look thicker or thinner.

then, for cool colors, do a gradient map adjustment layer over that:

and finally, my best friend, the overlay layer. just using a gradient here bc i'm lazy, but feel free to experiment with brushes, colors, and blending modes!

NOW GO. MAKE COOL SHIT WITH THE POWER OF MATH. AND SEND IT TO ME

also these are not hard and fast rules PLEASE mess around with them to see what kind of weird shit you can make. here's a gif. as you can see i added some random airblush blobs in the middle of it, for fun.

More in-depth thoughts on making the switch to csp? I’ve been debating it for a good while now and would love a secondary opinion! Also thoughts on having to use new brushes after the switch? <3

I'd been using krita since 2012, so it felt like i'd be cheating on it if i switched to csp. I think it was a combination of the fact that i know krita very well by now, plus i had made a whole bunch of pens on there and i'm pretty sure i can't bring them with me to csp, etc. oh and also the fact that krita is free. That was major for me, because i grew up without a lot of money and so i learned to work around getting expensive art supplies and such

However... Csp is totally worth it. It's been a process figuring out the set up and configurations, because it's not as simplified as krita (though krita has these same tools, some of them are different in either program. Some things are just two clicks in krita, and take longer in csp, while other things are a fifteen step process and krita, and csp already has an entire docker there waiting for you). But it's not too hard and it's fairly easy to look up anything i have questions about. They would be tied when it comes to set up, if not for the fact that csp has set ups ready to go for comics that feels a lot easier to work with. So that's win 1 for csp

Win 2 for csp was the brushes and stamps, etc that are on there. It takes a lot of getting used to, and i'm not a fan of the stabilization so far (not exactly sure if there is another option yet, but from what i can tell, individual brushes have stabilization options. Not bad, until i struggle to find an overall stabilization option, if there is one). In krita you can just hit "E" and it will turn whatever brush you're using into an eraser with the same texture and settings as the brush, and pressing "E" again turns it back. But in csp, erasers are limited and i don't like them very much.

But!! Texture,,, i'm a big fan of the everything else about the brushes. it kind of feels like working with actual physical materials (as much as it can). Watercolor mixes and acts like it's on real paper, etc etc. i'm really liking the pens that i found (because in csp, you really should be using the assets page to find brushes, or look up tutorials to make your own, but the default brushes are still amazing if you don't want to adventure out!). Krita is very limited on these. Csp sort of gives the effect of physical media and texture, whereas krita always has a digital look to it. If that makes sense? I'm not saying csp doesn't look digital, but it just has way more of that oomph that i've been wanting for my art for years now

All in all, i can say that i still recommend Krita, especially for beginners, and especially for people who can't afford to spend money on a program. It's still a VERY good place to draw and i'll likely still use it. It's a great starter and honestly, you don't have to make a change if you like it. But csp is also very much worth the money and you won't regret it
