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

问题

我想在Elasticsearch的pod中创建一个名为synonyms的文件夹，位于/usr/share/elasticsearch/位置下，使用我的部署YAML文件，我需要做哪些更改才能创建这个文件夹。

您可以使用init container创建文件夹，并使用您正在运行的command根据需要在主容器中使用它。

此外，您可以运行多个不同的Init容器，您可以使用一个容器来运行多个命令。

  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

请注意，这是一个YAML配置示例，用于创建具有多个命令的init容器，并设置文件夹的权限和所有权。

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
