21 Days of Docker-Day 4- Docker Container Under The Hood

Welcome to Day 4, so far we learned about the basics of Docker, let’s move our discussion from 10,000ft overview to 1000ft.

But before we go there based on the last 3 days knowledge, can you please answer a few of my questions?

Q1: What is the Kernel version of your Docker container?

Q2: Why the first process inside the Docker container run as PID 1?

Q3: How much default memory is allocated to my Docker container?

Q4: Is there is any way to restrict how much amount of memory we can allocate to the container?

Q5: How does container get its IP or able to communicate to the external world?

These are the question which pops up in my mind when I first start exploring docker, you may not have a answer to these question if you are new to Docker but if you already start thinking in this direction you are heading in right direction 🙂

  1. I was wondering if you ever considered changing the structure of your blog? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or two pictures. Maybe you could space it out better?

    1. Thanks for the feedback, I will try to add more pics in the future blog but at the same time, I want thing to be more technical rather than story telling
