persistPaths mounting as empty with multiple containers
dev:
replacePods:
- labelSelector:
app.kubernetes.io/component: app
persistPaths:
- path: /srv/app/public
containerName: php-container
- path: /srv/app/public
containerName: caddy-container
readOnly: true
persistenceOptions:
name: php-public
"php-container" writes files to "php-public" and "caddy-container" should be able to read it, but it doesn't. It loads an empty volume. Why?
@johnnypea that's strange, could you send us the replaced pod yaml? It should actually work like this.
Here you go...

@johnnypea thanks for the info, I see the problem now, your config needs to look like:
dev:
replacePods:
- labelSelector:
app.kubernetes.io/component: app
persistPaths:
- path: /srv/app/public
containerName: php-container
volumePath: php
- path: /srv/app/public
containerName: caddy-container
readOnly: true
volumePath: php
persistenceOptions:
name: php-public
The important bit is the volumePath as this will tell DevSpace to use the same path within the volume for your mounts.
@FabianKramm I see, thank you. Can volumePath be any acceptable path string?
@johnnypea yes it can, it's essentially the subPath on the persistent volume to use
