touch: cannot touch '/opt/couchdb/etc/local.d/docker.ini': Read-only file system

[adamko147]

When all ini files are mounted from ConfigMap into /opt/couchdb/etc/local.d couchdb won't start with error "touch: cannot touch '/opt/couchdb/etc/local.d/docker.ini': Read-only file system"

Expected Behavior

Since all configuration is provided in ini files (no environment variables needed) couchdb should start without problems

Current Behavior

currently docker-entrypoint.sh fails with "touch: cannot touch '/opt/couchdb/etc/local.d/docker.ini': Read-only file system"

Possible Solution

Possible solution would to touch the config file only when needed, e.g if admins not found in mounted config

Steps to Reproduce (for bugs)

Try to apply following manifest

apiVersion: v1
kind: ConfigMap
metadata:
  name: couchdb
data:
  couch.ini: |
    [admins]
    admin = -pbkdf2-c1f5f3ba577b63a07ccdb90929a1710d,d18f8ab420a27636470ae5205e082b27,10

    [couchdb]
    uuid = 792c574198077a896c234d9d99713b40
    single_node=true

    [couch_httpd_auth]
    secret = d5addf639614a8364d5e7d4def000b48
