Logrotate config interpets string as list

[vosdev]

Bug Overview

using the nginx_logrotate_conf values from defaults/logrotate.yml:

(I did change the www-data user to nginx..). I tried putting quotes around the path, no change in result.

nginx_logrotate_conf_enable: true
nginx_logrotate_conf:
  paths: /var/log/nginx/*.log # String or list of strings
    # - /var/log/nginx/*.log
  options: # daily # String or a list of strings
    - daily
    - missingok
    - rotate 14
    - compress
    - delaycompress
    - notifempty
    - create 0644 nginx adm # Changes NGINX log permissions
    - sharedscripts

results in /etc/logrotate.d/nginx:

/
v
a
r
/
l
o
g
/
n
g
i
n
x
/
*
.
l
o
g
{
    daily
    missingok
    rotate 14
    compress
    delaycompress
    notifempty
    create 0644 nginx adm
    sharedscripts
    postrotate
        if [ -f /var/run/nginx.pid ]; then
            kill -USR1 `cat /var/run/nginx.pid`
        fi
    endscript
}

Expected Behavior

/var/log/nginx/*.log {
    daily
    missingok
    rotate 14
    compress
    delaycompress
    notifempty
    create 0644 nginx adm
    sharedscripts
    postr

Changing the string to a list with one entry gave me a working result:

nginx_logrotate_conf_enable: true
nginx_logrotate_conf:
-  paths: /var/log/nginx/*.log # String or list of strings
+  paths:
+    - "/var/log/nginx/*.log" # String or list of strings
    # - /var/log/nginx/*.log
  options: # daily # String or a list of strings
    - daily
    - missingok
    - rotate 14
    - compress
    - delaycompress
    - notifempty
    - create 0644 nginx adm # Changes NGINX log permissions
    - sharedscripts
