No way to mount Single FIle.

[amanhigh]

I have usecase where i can't mount a directory but only a file.

Application uses a config /etc/tinyproxy.conf. Mounting /etc overrides all other configs. Hence there is need to just map single file.

Possible ways to do this

1. File using subPath from ConfigMap. But Voulmes don't support Config map currently.

2. Init Script that can run before Pod Start.

• Here i can mount my files /etc/tiny/tinyproxy.conf.
• Init Script can then copy /etc/tiny/tinyproxy.conf to /etc/tinyproxy.conf before starting Container.

The listed cases are not supported, but there is another solution that you can try.

https://gimlet.io/docs/onechart-reference#mounting-secrets-as-files

fileSecrets:
  - name: rabbitmq-conf
    path: /etc/rabbitmq
    secrets:
      rabbitmq.conf: |
        this is the conf file content
      definitions.json: |
        this
        is
        a
        multiline
        secret

It is technically a secret resource in k8s not a configmap.. you can add the file content in the values file.

Volumes configmap support is required feature and will land in OneChart. Thank you for the issue.

I tried this but it is not solving the problem, as it mounts the files however any files which exist in that directory would no longer be present. I have even tried adding Subpath as recommended in Stack Overflow. But this also leads to overwriting the full /etc/logrotate.d directory with one file default.conf in this case. fileSecrets: - name: config path: /etc/logrotate.d/ subPath: default.conf secrets: key.txt: Another File default.conf: | server { listen 80; server_name localhost; proxy_pass https://www.google.com/; } } Regards, Amanpreet Singh.

Oh, yes. I hate that problem.

Let me look at it.

hello @amanhigh,
The following use cases are possible now within onechart's volumes:

Case 1 (Mount an existing configMap as a file):

volumes:
- existingConfigMap: map
  path: /data/map.conf
  subPath: map.conf

Case 2 (Mount an emptyDir):

volumes:
- emptyDir: true
  path: /data
  name: empty

Case 3 (Mount a custom string as a file):

volumes:
- fileName: blabla.conf
  fileContent: |
     multi-line-text
     multi-line-text
  path: /data
