[Resolved] groupVersion shouldn't be empty

 

Issue:- 

When creating the simple resource like pod, replicaset, deployments etc got a groupVersion error specified below. 

Error:- 

 groupVersion shouldn't be empty

Effect:-

Not able to create the resource because of the above error

 apiversion: v1  
 kind: Pod  
 metadata:  
  name: pod2  
 spec:  
  containers:  
  - name: c1  
   image: nginx  

Resolution:-

If you look at the above configuration precisely you will find the apiversion  has been specified incorrectly. It should have been apiVersion  k.So just a difference of block letter can make that error. The same error will occur even if you forgot to mention the apiVersion in the configuration or it is misspelled. Below configuration will work fine.

 apiVersion: v1  
 kind: Pod  
 metadata:  
  name: pod2  
 spec:  
  containers:  
  - name: c1  
   image: nginx  

 

Explanation:-

apiVersion is hardcoded in the kubernetes. So if you misspell it, not use it or make a error in the Capital and small letter as well it will give the above error.
