Hello Ben Thank you for your time
I'm using this one: https://github.com/rrbarreto/ose-wordpress/blob/master/wordpress-template.json I see. So the files are being replaced when the PV is mounted because the image with the contents are created before, right ? > Your goal should be to have an image that is immutable w/ respect to application logic. I'm newbie with openshift / docker so I'd appreciate very much if you could give me any example from how I can do that Thank you Regards Robson 2016-07-08 13:18 GMT-03:00 Ben Parees <[email protected]>: > Not sure which wordpress image/example you're using since there are two in > there, but if you started from this one: > https://github.com/openshift/origin/blob/master/examples/wordpress/template/wordpress-mysql.json, > then the wordpress source lives in /opt/app-root/src within the image and > since you're mounting a PV to that path, you're replacing the > /opt/app-root/src image content with the contents of your PV. > > Fundamentally that wordpress image isn't designed to have > /opt/app-root/src be a volume. > > If you want the source code to be on a PV so you can safely edit it and > have your changes persisted, you need an image that's going to, on startup, > copy its source from a location within the image, to a location that you're > mounting the PV at, and then run the source from that PV directory. > > But in general that would not be a recommended pattern.
