从文件递归创建配置映射 [英] Create configmaps from files recursively

问题描述

我在两个目录中有多个配置文件.例如

I have multiple configuration files in two directories. For example,

• conf.d/parentconf1.conf
• con.d/node1/child1.conf
• conf.d/node2/child2.conf

我需要使用ConfigMap将这些配置文件以相同的目录结构安装到kubernetes pod.

I need to mount these configuration files in the same directory structure to kubernetes pod using ConfigMap.

尝试使用

kubectl create configmap --from-file=./conf.d --from-file=./conf.d/node1/child1.conf --from-file=./conf.d/node2/child2.conf. 

按预期创建的配置映射无法表达嵌套目录结构.

Config map created, as expected, cannot express the nested directory structure.

是否有可能从文件夹中递归创建ConfigMap，并且仍将文件夹结构保留在ConfigMap的键条目名称中-因为其目的是将这些ConfigMap挂载到Pod中?

Is it possible to create ConfigMap recursively from folders and still retain the folder structure in the name of the key entry for the ConfigMap - since the intention is to mount these ConfigMaps into pods?

推荐答案

不幸的是，当前不支持在configmap中反映目录结构.解决方法是像这样表达目录层次结构:

Unfortunately, reflecting directory structure in configmap is not supported currently. Workaround is to express directory hierarchy like this:

apiVersion: v1
kind: ConfigMap
metadata:
   name: testconfig
data:
  file1: |
    This is file1
  file2: |
    This is file2 in subdir directory
---
apiVersion: v1
kind: Pod
metadata:
  name: testpod
spec:
  restartPolicy: Never
  containers:
    - name: test-container
      image: gcr.io/google_containers/busybox
      command: [ "/bin/sh","-c", "sleep 1000" ]
      volumeMounts:
      - name: config-volume
        mountPath: /etc/config
  volumes:
    - name: config-volume
      configMap:
        name: testconfig
        items:
        - key: file2
          path: subdir/file2
        - key: file1
          path: file1
