Ahh, you're back. Good to see you again. What's that? You're anxious to hear more of the tale? Oh, ok - let's get going then, no reason to delay. Where was I.. ahh yes, videos.
That was round 1 of watching that particular set of videos, over the next couple of days I watched them at least 1 more time. Now I felt ready to sit down & work with containers.
Got the Ubuntu laptop out, set my iPad to the side with Chucks Docker video ready to go & started off. Following along with the video - mostly - I did not use the Linode cloud service, I did everything from my own laptop. That meant, of course, I had to do a bit of Googling & reading on how to install Docker on Ubuntu, which was pretty easy.

After the setup, I just followed along with NetworkChuck. Using Docker itself was fast, smooth & quite frankly fun! I did have to quickly learn a bit about Linux firewalls as I couldn't get the demo website that I deployed to load from any device on the network outside of my localhost. But hey, it's a learning opportunity & those are always valuable. Once I had that configured, everything worked as expected.
So what was my take-away? Well, I know how to install Docker on Linux, I can deploy & configure containers, I know how to manage/view those containers, & I understand the concepts of how Docker works & why it's so fast (hint: 1 kernel shared with the host OS & the container itself). I also picked up how I can manage the local Linux firewall.
So for the first 3-ish hours I've spent with Docker, I feel rather successful. This isn't the last of my walk with Docker, I'll have 1, maybe 2 more posts to finish off my tale.
Thanks for taking the time to read this. See ya next post!
