kubernetes: Pods can be composed of multiple containers

2 min read

One common misunderstanding with kubernetes is mistakenly assume "a pod" really means "a container".

A pod is the minimal unit we take into account in kubernetes but this does not mean that a pod is a container: A pod can be composed of several containers working together. We can easily see this on the READY column that are going to tell us for a given pod from how many containers it is composed:

$ kubectl  get pods
NAME                                     READY   STATUS      RESTARTS   AGE
ampa-7dcbfd689f-59ghw                    2/2     Running     0          5d1h
