问题描述
在使用Flux配置时,成功部署了一个HelmRelease。现在他想对其进行补丁。但他不确定如何使用这种补丁格式。以下是他当前的配置(没有postRenderers时,他不会出现错误):
apiVersion: kind: HelmReleasemetadata: name: ${elasticsearch_flx_app_name} namespace: ${elasticsearch_flx_app_name}spec: interval: 1m install: disableWait: true upgrade: disableWait: true chart: spec: chart: search-guard-flx version: "2.5.0" sourceRef: kind: HelmRepository name: my-oci namespace: flux-system postRenderers: - kustomize: patchesStrategicMerge: - apiVersion: apps/v1 kind: StatefulSet metadata: namespace: ${elasticsearch_flx_app_name} labels: app: ${elasticsearch_flx_app_name}-${cluster_env} test_label: foo values: # ... values omitted for brevity
他得到的错误是:
preparing upgrade for elasticsearch-flx resetting values to the chart's original version Warning error 55s (x4 over 29m) helm-controller reconciliation failed: Helm upgrade failed: error while running post render on files: trouble configuring builtin PatchStrategicMergeTransformer with config: ` paths: - '{"apiVersion":"apps/v1","kind":"StatefulSet","metadata":{"labels":{"app":"elasticsearch-flx-dev","test_label":"foo"},"namespace":"elasticsearch-flx"}}' `: '/{"apiVersion":"apps/v1","kind":"StatefulSet","metadata":{"labels":{"app":"elasticsearch-flx-dev","test_label":"foo"},"namespace":"elasticsearch-flx"}}' doesn't exist
用户解释说他的补丁意味着“在这个命名空间和这个应用标签中找到一个StatefulSet,并添加test_label: foo”。但在内联补丁中混合选择器和修改感觉有点奇怪。他可能误解了吗?
解决方案
请注意以下操作注意版本差异及修改前做好备份。
方案1
根据您提供的配置,您的补丁似乎有一些问题。在patchesStrategicMerge
中,您应该使用metadata
的labels
字段来指定要修改的StatefulSet的标签。以下是修复后的配置示例:
apiVersion: kind: HelmReleasemetadata: name: ${elasticsearch_flx_app_name} namespace: ${elasticsearch_flx_app_name}spec: interval: 1m install: disableWait: true upgrade: disableWait: true chart: spec: chart: search-guard-flx version: "2.5.0" sourceRef: kind: HelmRepository name: my-oci namespace: flux-system postRenderers: - kustomize: patchesStrategicMerge: - apiVersion: apps/v1 kind: StatefulSet metadata: labels: app: ${elasticsearch_flx_app_name}-${cluster_env} spec: template: metadata: labels: test_label: foo values: # ... values omitted for brevity
在上面的示例中,我们将metadata
的labels
字段移动到了正确的位置,并在spec
下的template
中添加了labels
字段。这样,补丁将正确地修改StatefulSet的标签。
方案2
如果您觉得在内联补丁中混合选择器和修改有点奇怪,您可以尝试使用单独的补丁文件来修改StatefulSet。以下是一个示例补丁文件的配置:
apiVersion: apps/v1
kind: StatefulSet
metadata:
namespace: ${elasticsearch_flx_app_name}
labels:
app: ${elasticsearch_flx_app_name}-${cluster_env}
spec:
template:
metadata:
labels:
test_label: foo
您可以将上述内容保存为一个单独的文件(例如statefulset-patch.yaml
),然后在patchesStrategicMerge
中引用该文件:
apiVersion: kind: HelmReleasemetadata: name: ${elasticsearch_flx_app_name} namespace: ${elasticsearch_flx_app_name}spec: interval: 1m install: disableWait: true upgrade: disableWait: true chart: spec: chart: search-guard-flx version: "2.5.0" sourceRef: kind: HelmRepository name: my-oci namespace: flux-system postRenderers: - kustomize: patchesStrategicMerge: - statefulset-patch.yaml values: # ... values omitted for brevity
这样,您可以将选择器和修改分开,并更清晰地管理补丁文件。
方案3
如果您仍然遇到问题,可能是由于版本差异或其他原因导致的。在这种情况下,您可以尝试查看相关文档或寻求社区支持以获取更多帮助。
