Now I have a situation that I have same yaml files, each of them contains things like deployment, service, ingress, etc. I have to create them concurrently, I tyied ansible to achive if but failed, so I want to know if kubernetes has an API endpoint can post the yaml file to it and create resources like what the command kubectl create -f sample.yaml did.You can also give me other advice to achive my purpose if you like.
I can also accept if there's a way to post my yaml file to kubernetes api and create all resources in it
Then you can simply concatenate all individual yaml files into one big yaml file but each separted by --- in between.
For example to install kubernetes-dashboard you simply use: kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml, examination of this yaml file reveals structure you need (excerpt below):
...
# ------------------- Dashboard Secret ------------------- #
apiVersion: v1
kind: Secret
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-certs
namespace: kube-system
type: Opaque
---
# ------------------- Dashboard Service Account ------------------- #
apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system
---
# ------------------- Dashboard Role & Role Binding ------------------- #
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: kubernetes-dashboard-minimal
...where each block between comments could be separate yaml file. Note that comments are optional and separator between contents of individual yaml files is ---.
Just some sidenotes:
--recursive switch to kubectl as detailed in the official documentation and run against folder that contains all individual yaml files. This way you retain capability to individually pick any yaml file, and can deploy/delete/apply... all at once if you choose so...
