kubernetes - 使用不同名称的 kustomization.yaml

Question

出于 CI/CD 的目的，该项目正在维护 2 个 kustomization.yaml 文件

常规部署 - kustomization_deploy.yaml

回滚部署 - kustomization_rollback.yaml

要运行 kustomize build，当前目录中需要一个名为“kustomization.yaml”的文件。
如果项目想要使用 kustomization_rollback.yaml 而不是 kustomization.yaml，这怎么可能？ kustomize 是否接受文件名作为参数？文档对此没有指定任何内容。

Answer 1

目前无法改变 kustomize 的行为支持其他文件名(通过使用预编译的二进制文件)，而不是:

kustomization.yaml

kustomization.yml

Kustomization

以下所有情况都会产生相同的错误输出:

kubectl kustomize dir/

kubectl apply -k dir/

kustomize build dir/

Error: unable to find one of 'kustomization.yaml', 'kustomization.yml' or 'Kustomization' in directory 'FULL_PATH/dir'

根据 CI/CD 平台/解决方案/工具，您应该尝试其他方式，例如:

拆分Deployment进入 2 个目录 kustomization_deploy/kustomization_rollback与 kustomization.yaml

As a side note!

File names that kustomize uses are placed in the:

• /kubernetes/vendor/sigs.k8s.io/kustomize/pkg/constants/constants.go

// Package constants holds global constants for the kustomize tool.
package constants

// KustomizationFileNames is a list of filenames that can be recognized and consumbed
// by Kustomize.
// In each directory, Kustomize searches for file with the name in this list.
// Only one match is allowed.
var KustomizationFileNames = []string{
  "kustomization.yaml",
  "kustomization.yml",
  "Kustomization",
}

The logic behind choosing the Kustomization file is placed in:

• /kubernetes/vendor/sigs.k8s.io/kustomize/pkg/target/kusttarget.go
