Intro to Docker - A Tool Every Developer Should Know

Docker is a powerful tool that allows developers to set up environments quickly, configure complex systems and servers easily, and deploy software reliably, yet it is also a source of great confusion. In this video, we will get a look at what Docker is, how it works, and how to use it in our development tasks. Once you get used to how Docker works, it will become a valuable part of your development process.

Hey Tim, just a little note: docker ps -a is docker ps -a (and not something else) because it mimics UNIX 'ps' command, which stands for "processes"; '-a' stands for 'all', so basically you say "hey docker, list all processes (containers/apps)!" I hope someone will find this useful and it will help them remember the command

A suggestion, maybe you can create practice course videos, in order, you have different scenarios where you need to fix a bug, or you have to refactor some complex code. Something that you had to deal with in your career. That way you don't only teach us concepts but teach us how to think, and what tool is useful.

[@shreyasjejurkar1233]

Just for more info. In docker build command Tim mentioned that . (dot), it's not dot technically it's the relative path to dockerfile from that current location. Tim open terminal in the same folder as the dockerfile, that is why it's . (dot) meaning current folder location because there is actual dockerfile from which Tim wanted to create image. If the dockerfile is in subfolder, then instead of .(dot) we will have path to that file.
BTW Great intro, Tim! 🙌

One thing I was able to do with docker that is really great is I was able to create a system where when I do a build, after the build is done, it will run my custom program that will publish without build. After the publish, then it would create a docker file. Which would just copy the files, set the ports and use the entry points. It would first delete the old containers then rerun again. It allowed to be able to have something with docker that runs all the time. Even was able to map 2 common folders on my C drive and do the code in the way where the code is the same whether the docker or non docker version is used. I even was able to connect to the site from another computer on the network without firewall issues as long as ssl was not used. Its a great alternative to windows services.

I'm always wondering (and haven't looked it up yet) is how docker handles different architectures. I.e. what if I make my image on an x86 architecture and want to run it on arm64? Does it use emulation?

[@SunilMehta131]

important note for people who are trying above - the dockerfile should be named as "Dockerfile" otherwise it may result in an error like this - failed to solve with frontend dockerfile.v0: failed to create LLB definition: the Dockerfile cannot be empty

@@IAmTimCorey No worries. It's somewhat counterintuitive as you assume you drag it up as that's how nesting works, but dragging it down always works :)
