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.

[@vadimstepanov239]

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

[@IAmTimCorey]

Thanks for sharing.

[@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! 🙌

You're so good at explaining complex technologies, you make it so easy! thank god I found your channel, I'm learning a lot 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. Regards from Argentina.

Top Tip: if you want to move a file to the top level folder of the project, drag it BELOW all the other files. The entire file list sidebar will be highlighted and your file to move to the root :)

[@IAmTimCorey]

Thanks for the tip!

[@thfreakinacage]

@@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 :)

[@angel_machariel]

For me, file handling such as moving, compressing and so forth, between multiple network locations is crucial. Do images exist to create virtual network locations so can test "live" said file operations? I'm using a "worker" service to do these things and a console program to start/stop the service and whatnot.

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.

That's a bit outside the scope of what I cover. I'm glad you are enjoying my content, though.

[@mikebreeden6071]

Another very useful video. Thank you very much. I will take the course if I have the time... but you know, crushed now. Docker might be able to remove some of the crush though. While web isn't my main thing, one of my projects is an Intranet (with a bunch of AJAX functionality). Say my website was the only site on that IIS server... and I had control of the server. (This would actually apply to any website). Say the website was written in .Net Core(y) instead of .Net Framework. What would be the difference between me installing the website to IIS (with the .Net Core handler) and installing it in a Container with Apache? Would there be a performance difference? Would there be anything to consider besides Db connections and file access?

[@simon-white]

Great intro! 42:04 docker ps "why is it not docker containers?" Turns out it is 😃 it's just an alias for "docker container ls" or "docker container list". Their documentation has a whole bunch of aliases. Sometimes the original commands are easier to remember as the logic is more apparent.

[@IAmTimCorey]

Thanks for sharing. But what does the "ps" stand for? I could see CL for container list or CO for containers or CS for the same. It's just interesting that they chose PS.

[@simon-white]

@@IAmTimCorey I asked the AI bots, they said ps means Process Status. Whether or not it's true, it makes sense; it's a similar operation to Get-Process in PowerShell, which gets processes and indicates whether they're running or not.
