Is this a request for help?:
When we deploy azure npm in a k8s alpha or beta version cluster, azure-npm is always in failing state, k8s version parsing is failing, and there are even on logs showing why it's failing:
|
// CompareK8sVer compares two k8s versions. |
|
// returns -1, 0, 1 if firstVer smaller, equals, bigger than secondVer respectively. |
|
// returns -2 for error. |
|
func CompareK8sVer(firstVer *version.Info, secondVer *version.Info) int { |
|
firstMajor, err := strconv.Atoi(firstVer.Major) |
|
if err != nil { |
|
return -2 |
|
} |
|
|
|
firstMinor, err := strconv.Atoi(firstVer.Minor) |
|
if err != nil { |
|
return -2 |
|
} |
|
|
|
secondMajor, err := strconv.Atoi(secondVer.Major) |
|
if err != nil { |
|
return -2 |
|
} |
|
|
|
secondMinor, err := strconv.Atoi(secondVer.Minor) |
|
if err != nil { |
|
return -2 |
|
} |
|
|
|
if firstMajor < secondMajor { |
|
return -1 |
|
} |
|
|
|
if firstMajor > secondMajor { |
|
return 1 |
|
} |
|
|
|
if firstMinor < secondMinor { |
|
return -1 |
|
} |
|
|
|
if firstMinor > secondMinor { |
|
return 1 |
|
} |
|
|
|
return 0 |
|
} |
|
|
|
// IsNewNwPolicyVer checks if the current k8s version >= 1.11, |
|
// if so, then the networkPolicy should support 'AND' between namespaceSelector & podSelector. |
|
func IsNewNwPolicyVer(ver *version.Info) (bool, error) { |
|
newVer := &version.Info{ |
|
Major: k8sMajorVerForNewPolicyDef, |
|
Minor: k8sMinorVerForNewPolicyDef, |
|
} |
|
|
|
isNew := CompareK8sVer(ver, newVer) |
|
switch isNew { |
|
case -2: |
|
return false, fmt.Errorf("invalid Kubernetes version") |
|
case -1: |
|
return false, nil |
|
case 0: |
|
return true, nil |
|
case 1: |
|
return true, nil |
|
default: |
|
return false, nil |
|
} |
|
} |
failing k8s version could be like this: 1.17.0-beta.1
