Resource constraints problem

Rancher 1.x

Hi

I’m using “Bind9 Domain Name Server” from catalog and everything it’s working fine

i have tried to download the configuration , delete the stack and create from composer files and i got this error :

bind9 (Failed to allocate instance [container:1i706]: Bad instance [container:1i706] in state [error]: Allocation failed: No healthy hosts meet the resource constraints: [53:53/tcp, 53:53/udp portReservation, instanceReservation: 1].)

but no other dns servise is running on hosts.

rebuild the stack from catalog work as usual.

Hi
i found the problem , was the label io.rancher.container.system defined on hosts.
but i don’t understand why using catalog the problem don’t arise.
