How to update chia docker with persistent option?

[mcybz]

So I created a docker with the "persistent" option instead of -v mount points. I haven't read anywhere how this affects upgrades? Don't want to lose the config but also need to update to 1.8.1.

Here was the initial command used to launch the container:

sudo docker run --name mychia -e service="wallet" -e keys="persistent" -d ghcr.io/chia-network/chia:1.5.0

Currently the container is running. I've done a

docker pull ghcr.io/chia-network/chia:latest

But not sure what next step is. I see people talking about "deleting the container" that sounds like my keys are gonna go ..."poof". Bit cautious and unsure how to proceed.

Appreciate any guidance here
