1. 背景
当我们写了一遍vaule.yaml，再写一遍value.schema.json这是非常繁琐的。因此，有这样一块关于 helm 的插件使用一条命令即可达到目的。
2. 安装
该插件适用于 Helm v2 和 v3 版本，因为它与 Helm 二进制版本无关
$ helm plugin install https://github.com/karuppiah7890/helm-schema-gen.gitkaruppiah7890/helm-schema-gen info checking GitHub for tag '0.0.4'karuppiah7890/helm-schema-gen info found version: 0.0.4 for 0.0.4/Darwin/x86_64karuppiah7890/helm-schema-gen info installed ./bin/helm-schema-genInstalled plugin: schema-gen
复制代码
或者你也可以下载helm-schema-gen命令
tar tvf helm-schema-gen_0.0.4_Linux_x86_64.tar./helm-schema-gen --helpmv helm-schema-gen /usr/local/bin/
复制代码
3. 用法
该插件适用于 Helm v2 和 v3 版本
让我们采取 values.yaml 如下示例
replicaCount: 1
image: repository: nginx pullPolicy: IfNotPresent
imagePullSecrets: []nameOverride: ""fullnameOverride: ""
serviceAccount: # Specifies whether a service account should be created create: true # The name of the service account to use. # If not set and create is true, a name is generated using the fullname template name:
podSecurityContext: {} # fsGroup: 2000
securityContext: {} # capabilities: # drop: # - ALL # readOnlyRootFilesystem: true # runAsNonRoot: true # runAsUser: 1000
service: type: ClusterIP port: 80
ingress: enabled: false annotations: {} # kubernetes.io/ingress.class: nginx # kubernetes.io/tls-acme: "true" hosts: - host: chart-example.local paths: [] tls: [] # - secretName: chart-example-tls # hosts: # - chart-example.local
resources: {} # We usually recommend not to specify default resources and to leave this as a conscious # choice for the user. This also increases chances charts run on environments with little # resources, such as Minikube. If you do want to specify resources, uncomment the following # lines, adjust them as necessary, and remove the curly braces after 'resources:'. # limits: # cpu: 100m # memory: 128Mi # requests: # cpu: 100m # memory: 128Mi
nodeSelector: {}
tolerations: []
affinity: {}
复制代码
现在，如果您使用插件并将 传递values.yaml给它，您将获得 JSON Schemavalues.yaml
$ helm schema-gen values.yaml{ "$schema": "http://json-schema.org/schema#", "type": "object", "properties": { "affinity": { "type": "object" }, "fullnameOverride": { "type": "string" }, "image": { "type": "object", "properties": { "pullPolicy": { "type": "string" }, "repository": { "type": "string" } } }, "imagePullSecrets": { "type": "array" }, "ingress": { "type": "object", "properties": { "annotations": { "type": "object" }, "enabled": { "type": "boolean" }, "hosts": { "type": "array", "items": { "type": "object", "properties": { "host": { "type": "string" }, "paths": { "type": "array" } } } }, "tls": { "type": "array" } } }, "nameOverride": { "type": "string" }, "nodeSelector": { "type": "object" }, "podSecurityContext": { "type": "object" }, "replicaCount": { "type": "integer" }, "resources": { "type": "object" }, "securityContext": { "type": "object" }, "service": { "type": "object", "properties": { "port": { "type": "integer" }, "type": { "type": "string" } } }, "serviceAccount": { "type": "object", "properties": { "create": { "type": "boolean" }, "name": { "type": "null" } } }, "tolerations": { "type": "array" } }}
复制代码
您可以将其保存到这样的文件中
$ helm schema-gen values.yaml > values.schema.json
复制代码
如果是下载的helm-schema-gen命令
helm-schema-gen value.yaml > values.schema.json
复制代码
