Not able to make a folder in elasticsearch pod using yaml file

问题

我想在 Elasticsearch pod 内部创建一个名为 synonyms 的文件夹，位置在 /usr/share/elasticsearch/ 下，我应该如何修改我的部署 YAML 文件以实现这一目标。

这是我的部署清单文件：

  1. apiVersion: apps/v1
  2. kind: Deployment
  3. metadata:
  4.   name: elasticsearch
  5.   namespace: elk
  6. spec:

  43.           mountPath: /usr/share/elasticsearch/synonyms  # 挂载到 Elasticsearch pod 的路径
  44.         env:
  45.           - name: cluster.name
  46.             value: elasticsearch-cluster
  47.           - name: node.name

  57.           - name: network.host
  58.             value: "0.0.0.0"
  59.       initContainers:
  60.       - name: fix-permissions
  61.         image: busybox
  62.         command: ["sh", "-c", "chown -R 1000:1000 /usr/share/elasticsearch/data"]
  63.         securityContext:
  64.           privileged: true
  65.         volumeMounts:
  66.         - name: data-volume
  67.           mountPath: /usr/share/elasticsearch/data
  68.       - name: increase-vm-max-map
  69.         image: busybox
  70.         command: ["sysctl", "-w", "vm.max_map_count=262144"]
  71.         securityContext:
  72.           privileged: true
  73.       - name: increase-fd-ulimit
  74.         image: busybox
  75.         command: ["sh", "-c", "ulimit -n 65536"]
  76.         securityContext:
  77.           privileged: true
  78.       volumes:
  79.         - name: data-volume
  80.           persistentVolumeClaim:
  81.             claimName: elasticsearch-pvc  # 为数据存储创建一个 PVC
  82.         - name: synonyms-volume  # 添加这一行用于 synonyms 文件夹挂载
  83.           emptyDir: {}  # 创建一个空目录供挂载

请注意，我已经在容器部分添加了一个新的 volumeMount 来挂载 synonyms 文件夹，并在 volumes 部分创建了一个名为 synonyms-volume 的空目录，用于挂载到 Elasticsearch pod 内部的 /usr/share/elasticsearch/synonyms 路径上。这样，你就可以在该位置创建 synonyms 文件夹了。

您可以使用init容器创建文件夹，并使用您正在运行的命令以后根据需求使用主容器。

此外，如果您正在运行多个不同的init容器，您可以使用一个容器来执行多个命令。

  1. dnsPolicy: ClusterFirst
  2. initContainers:
  3. - command:
  4.   - sh
  5.   - -c
  6.   - chown -R 1000:1000 /usr/share/elasticsearch/data
  7.   - mkdir /usr/share/elasticsearch/XYZ
  8.   - sysctl -w vm.max_map_count=262144
  9.   - chmod 777 /usr/share/elasticsearch/data
  10.   - chomod 777 /usr/share/elasticsearch/data/node
  11.   - chmod g+rwx /usr/share/elasticsearch/data
  12.   - chgrp 1000 /usr/share/elasticsearch/data
  13.   image: busybox:1.29.2
  14.   imagePullPolicy: IfNotPresent
  15.   name: set-dir-owner
  16.   resources: {}
  17.   securityContext:
  18.     privileged: true
  19.   terminationMessagePath: /dev/termination-log
  20.   terminationMessagePolicy: File
  21.   volumeMounts:
  22.   - mountPath: /usr/share/elasticsearch/data
  23.     name: elasticsearch-data
  24. restartPolicy: Always
英文:

You can create the folder using init container with command that you are running and utilize it as per requirement later with Main container.

Also, you are running multiple different Init containers you can keep one container with multiple commands

  1.   dnsPolicy: ClusterFirst
  2. initContainers:
  3. - command:
  4. - sh
  5. - -c
  6. - chown -R 1000:1000 /usr/share/elasticsearch/data
  7. - mkdir /usr/share/elasticsearch/XYZ
  8. - sysctl -w vm.max_map_count=262144
  9. - chmod 777 /usr/share/elasticsearch/data
  10. - chomod 777 /usr/share/elasticsearch/data/node
  11. - chmod g+rwx /usr/share/elasticsearch/data
  12. - chgrp 1000 /usr/share/elasticsearch/data
  13. image: busybox:1.29.2
  14. imagePullPolicy: IfNotPresent
  15. name: set-dir-owner
  16. resources: {}
  17. securityContext:
  18. privileged: true
  19. terminationMessagePath: /dev/termination-log
  20. terminationMessagePolicy: File
  21. volumeMounts:
  22. - mountPath: /usr/share/elasticsearch/data
  23. name: elasticsearch-data
  24. restartPolicy: Always
