I cannot tell you how many times I have tried to "Dockerize" my side projects ... this will be a great talk! Thank you @nickpalenchar ! 🔥
So glad to see a talk like this. All new devs should know about containers and their portability for cloud-native development. KUDOS, Nick.
I did not know about the layer hashes. Really useful!
Agreed! Super underrated!
Hi Nick! Docker is definitely well known nowadays; are there are container technologies that you've tried or heard of?
Hey Andy, I haven't tried any other container technologies--Docker has always suited my needs so I've never felt the need to explore alternatives. Although I have heard of rkt, and the Open Container Initiative Standard also looks interesting as a concept, though I know nothing of either.
What a great Docker introduction! Loved the ocean/whale metaphor, and a great walkthrough of some of the basic concepts, commands, and errors. Great talk!
Hey Nick! Awesome talk; I actually wanted to ask you what inspired you to make the transition from acting/directing to tech? I'm someone who's in between those two worlds, working a full tech job while enjoying the acting bits here and there. I'm curious about what your story is?
Great question Nic. I have a strong arts background and even went to a performing arts high school--it's where I got a lot of foundational leadership skills and of course plenty of practice in public speaking. Lesser known though was that I did some small time video game programming but never could fathom understanding computer science formally, so I avoided it for the greater part of my upbringing. I discovered freeCodeCamp after graduating college and helped form meetups in New York City. It eventually inspired me to complete a Coding Bootcamp and break into the industry. My theatre skills have helped me tremendously with leadership and team morale, which anyone would agree are important parts to the software collaboration process!
Wow, that's awesome Nick. I can relate, that theater has helped with both team morale and leadership. Thanks for sharing (: I'll have to also start learning Docker 😅👏🏿
Awesome talk @nickpalenchar ! What are some of the benefits of using a container such as Docker when you are building software? What do you primarily use it for in your day to day job?
Thanks Molly! There are many key benefits but in one way or another it all comes back to portability, and that's useful at any phase in development.
For sandbox/prototyping, I might want to try out a new thing without muddling my local environment. I'll search docker hub for a container (say python3), and run the tag on my machine with
docker run <tag_name>, and boom--I have all the correct binaries installed in the container without having to install anything myself. When I'm done with it, I can remove the container. My local environment never gets cluttered at any point in thisFor production, it's often said containers helps eliminate the "runs on my computer" type of surprises. Running a container creates an isolated environment that's identical rather its in your computer or a remote server.
is Docker free to run? Do we need to to have a linux system running on a server service like aws?
Hi Paul,
Docker is free to run and you can install it on your Window, MacOS and Linux machine.
Thank you, @scooterphoenix . I tried it on windows and it got difficult to set up, which I then abandoned. It's much straight forward in setting it up in a Linux system. After creating a simple container, I just didn't know where or how to deploy. I will have to try it once again from scratch.
Sorry you had a bum time with Docker on Windows. Maybe we should have a container chat in one of the chat rooms. Once you create your app and create an image from it, you can share that image with others to build upon and use or you can deploy your image to AWS Fargate or if your app requires high availability, then some sort of container orchestration is what you'd look at, like EKS.
Great talk Nick! Love learning a bit more about Docker. What's the best use case for using Docker containers? Is it mainly used to deploy to production? Or can we use it for development as well?
As someone who has used docker, but mostly through cut and paste this is really interesting. Curious what people who haven't used docker before think.
Love this talk! Docker has been a bit of a mystery to me for too long. What are the key benefits of using Docker?
I am so glad to listen to this talk. I will docker to my web dev journey. Thank you for the introduction.
Docker has always been hard for me to get into learning and this talk was a wonderful way to get introduced to what Docker is and how to use it. Thanks Nick!
