Question on Kubernetes

In the below yaml file in the training we create a POD. Is that within the POD we are running a container of nginx ?apiVersion:v1
kind: Pod
metadata:
name: nginx
labels:
app: nginx
tier: frontend
spec:
containers:

  • name: nginx
    image: nginx
#2

It looks like it is indeed a pod running the nginx image.

BTW: you should take YAML and put it into a code block using the </> key, since otherwise the appears of your YAML will be completely garbled, as you have above. So it looks like this:

apiVersion: v1
kind: Pod
metadata:
  labels:
    run: nginx
  name: nginx
spec:
  containers:
  - image: nginx
    name: nginx
#3

When you say POD running with nginx image. In a POD you will have containers . And you can spin multiple POD’s. Are you saying that the POD itself is like a machine with nginx or a container with nginx. And within that container/POD we can run multiple containers? Sorry to ask as i am just starting my journey with kubernetes

or

Is it that the POD is a logical entity or logical grouping and within that we have created a container with nginx ?

A pod is a sort of grouping of containers (one or more) that handle things like networking, shared volumes, policies for handling failed containers, and certain security settings. So you can think of a pod as something that “contains” one or more containers. It makes it easier to manage containers, and easier to group containers that need to work very closely together.

#5

so in the below i am just creating a POD and running a container within that POD correct?

apiVersion: v1
kind: Pod
metadata:
labels:
run: nginx
name: nginx
spec:
containers:

  • image: nginx
    name: nginx

That’s a good way of thinking about it, yes. You’re running a pod; the pod is running an nginx container.
