📄️ Edit a POD
Remember, you CANNOT edit specifications of an existing POD other than the fields below:
📄️ Microservices
At times you may need two micro services which were developed and deployed separately to work together such as a web server and a logging service. And that is why you have multi container pods that share the same lifecycle which means they are created together and destroyed together. They share the same network space which means they can refer to each other as local host and they have access to the same storage volumes.
📄️ Node Affinity
nodeSelector provides a very simple way to constrain pods to nodes with particular labels.
📄️ Node Selection
You have different kinds of workloads running in your cluster.
📄️ Resources
The Scheduler that decides which node a part goes to.
📄️ Scheduling
A scheduler takes care of placing new pods onto nodes within the cluster.
📄️ Secrets
- Convert your secret data to a base-64 representation
📄️ Security Context
SecurityContext is one option to make sure that containers and pods don't request more than what it should request in terms of process privileges.
📄️ Services
Single-point entry to access one/more pods because
📄️ Deployment and StatefulSet
Similarities and Differences
📄️ Storage Classes
Volumes are used by pods to store data.
📄️ Taints and Tolerations
Taints and tolerations are used to set restrictions on what pods can be shared.Taints and tolerations have nothing to do with security or intrusion on a cluster.
