I'm thinking of creating a website and l'm thinking of using docker in the process. How do I use it in the creation of my website ?
Been seeing a lot of these threads with impossibly open-ended barely tenuous one-liner quotations being posted around technical communities. Is those a new AI thing?
Hi, Mr. Docker.
You seem pretty active on Lemmy. But it also looks like you really don't like using search engines.
Some might say "bait". But, judging by your past activity, it just seems like this is your usual behavior.
So, please, before littering these communities with low-effort posts, use a search engine like DuckDuckGo, or Qwant.
Also, why do you think you even need Docker? I find it funny how you named your profile after something you don't know much about.
You mean this ?
Yes. It looks like it is not working in India. It was just an example I used to avoid mentioning Google. There are many others.

Good One 😆😆😆
You would use docker to host the website itself either using Nginx, Apache, or WordPress depending on the complexity of your site.
This totally depends on what you want out of your website. Describe it to us.
Is it a static page (meaning just serving up some html and associated images?) If so, Docker will be a waste of time.
No, it's going to be a dynamic website, having videos, and also changes would be made in the given data as per convenience.
You can run really any webserver setup with docker, so once you figure out what you need then you can set up your docker-compose stack.
For example for PHP sites that might be nginx, php-fpm, and mariadb containers.
Docker is just going to be used to run the applications which host your website. What you need to decide first is what your website will be and that will inform the decision on what technologies will be used to host your website. For example, if you are thinking of something like a blog, you might choose WordPress as the main hosting platform. This will need some sort of database behind it, for which you might choose MySQL or Postgres. You would also need some sort of web server software, which you might choose Nginx or Apache. At a basic level, you could now have the entire web stack defined: E.g. WordPress, MySQL, Nginx.
Ok, so now you need to sort out where those technologies will run. The easy, older solution is to spin up a physical box and load all of the software packages on the native Operating System (OS) of that box. This works perfectly well, until it's time to start patching and updating the OS and software. And you will want to do those updates. This will probably go well for the first few upgrades, but eventually something will go sideways. Often this will be that several of your software packages will require different version of the same, underlying library. Or, something will just not install right and your website stops working. This is where docker comes in.
Docker lets you run each software package in it's own contained environment. Each application runs in it's own container, and the other containers are only reached via network calls. It's like having a separate virtual machine for each service (this is how we used to actually run stuff like this); but, without all the overhead of actually having multiple virtual machines. So, even if you upgrade package XYZ in the Nginx container to version 2.1, the MySQL container could have package XYZ still running at version 1.9. Neither container knows or cares about what is running in the other containers.
The other advantage of containers is that the base OS and software in the container is usually well defined and doesn't change much. The container will be able to reach permanent storage for any configuration and data files. But, if something goes wrong with the OS or software inside the container, then that container is destroyed and a new copy spun up and attached to the config/data storage. Software upgrades can also take advantage of this, as you can often stop the current container and start a container running the new version of the software, attach it to the config/data storage and maybe run some sort of "upgrade database" command. This makes for less mistakes and chances for things to not go well.
If your goal is to learn to self host, I would recommend putting those posts over in the !selfhosting@slrpnk.net. They are likely to get a better reception than in the programming and Linux communities you spammed with this post. Though, even there you may run into a bit of the RTFM! vibe you got here if you are posting questions without context and which appear to be low effort "I want to do something but have made no attempt to learn anything on my own". I'd recommend spending some time reading long form blogs/guides on web hosting and watching YouTube videos. Again, long form stuff. Skip the clik-bait-y crap with titles like "get your website running in 5 minutes!
<insert stupid emojis here>
". You'll want to learn the basics on Docker and what is required to run and host a web site. Once you are able to get containers going, try setting up a web stack on your local system (don't go paying for anything yet) and see if you can get it working and understand how it works. You're almost certainly going to screw it up a few times in the process, that's ok. That's another great feature of containers, you can bork them up really, really bad and not have to care. You delete the container, maybe wipe the attached storage and try again.Good luck.
Docker is a tool for packaging your application and all its dependencies into a container. This means that your application will work the same on any machine - yours, the developers', and the server.
Why do you want to use docker?
You should have a use-case for the technology first.
