# Using a filesystem volume:
quarkus.datasource.devservices.volumes."/path/from"=/container/to <1>
# Using a classpath volume:
quarkus.datasource.devservices.volumes."classpath:./file"=/container/to <2>
quarkus.datasource.devservices.volumes."classpath\:./file"=/container/to <2>
----

<1> The file or folder "/path/from" from the local machine will be accessible at "/container/to" in the container.
<2> When using classpath volumes, the location has to start with "classpath:". The file or folder "./file" from the project's classpath will be accessible at "/container/to" in the container.

CAUTION: The colon character `:` needs to be escaped in `.properties` files as `\:`, or it will be interpreted as a key/value separator.

IMPORTANT: when using a classpath volume, the container will only be granted read permission. On the other hand, when using a filesystem volume, the container will be granted read and write permission.
