如何使用go模板将值与字符串进行比较

Question

我想循环遍历一个值文件，在/中为该名称空间创建一个名称空间和一个网络策略，默认情况除外。我只想创建策略，而不是默认的命名空间，因为默认情况下它就在那里。

值文件：

namespaces:
- name: default
- name: test1
- name: test2

模板文件：

# Loop through the namespace names and create the namespaces
{{- range $namespaces := .Values.namespaces }}
{{- if ne "default" }}
apiVersion: v1
kind: Namespace
metadata:
name: {{ $namespaces.name }}
---
{{- end }}
{{- end }}
# Loop through the namespace names and create a network policy for those namespace
{{- range $namespaces := .Values.namespaces }}                                                                                                                                                             
---                                                                                                                         
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: {{ $namespaces.name }}-networkpolicy
namespace: {{ $namespaces.name }}
spec:
podSelector: {}
ingress:
- from:
- namespaceSelector:
matchLabels:
name: {{ $namespaces.name }}
---                                                                                                                         
{{- end }} 

我得到的错误是：

Error: UPGRADE FAILED: template: namespaces/templates/namespaces.yaml:3:7: executing "namespaces/templates/namespaces.yaml" at <ne>: wrong number of args for ne: want 2 got 1

这可能很简单，但没有看到。希望有人能帮忙。

这对我有效：

# Loop through the namespace names and create the namespaces
{{- range $namespaces := .Values.namespaces }}
{{- if ne $namespaces.name "default" }}
apiVersion: v1
kind: Namespace
metadata:
name: {{ $namespaces.name }}
---
{{- end }}
{{- end }}
# Loop through the namespace names and create a network policy for those namespace
{{- range $namespaces := .Values.namespaces }}                                                                                                                                                             
---                                                                                                                         
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: {{ $namespaces.name }}-networkpolicy
namespace: {{ $namespaces.name }}
spec:
podSelector: {}
ingress:
- from:
- namespaceSelector:
matchLabels:
name: {{ $namespaces.name }}
---                                                                                                                         
{{- end }}
