Unbound in docker dropping dns_net network after startup

[bmwhd123]

I have been using your examples to run pihole and unbound in containers on docker (deployed with portainer on raspberry pi). It worked well the first time I deployed it but upon a reboot of the raspberry, the unbound container starts, gets the local IP on the proper subnet that is configured for pihole to forward to, but then after a few seconds drops off that local network. In the unbound container log I'm seeing a single error repeated over and over: exec /unbound.sh exec format error

Here's my yml file:

Never mind. Fat fingered the path to the rpi version. All good.

Closing as resolved. Wrong image link used.
