upgrade from 0.2.2 to latest version with already running containers

[phwoelfel]

Hello!

I'm currently on version 0.2.2 and would like to upgrade to the latest version of colima. The README says that I have to use colima delete and then colima start because I'm upgrading from pre 0.3.4.
I couldn't find out in the docs if colima delete will also remove the data thats stored in my container volumes/colima VM.

I have a postgresql container I'm using for development and which I would like to keep using after the upgrade.

So how can I upgrade colima from 0.2.2 to 0.4.2 without loosing my container data/volumes? Will colima delete keep the data and just remove the VM without touching my container volumes?

Thanks!

@phwoelfel unfortunately for now, there is no easy way around this.

You can try the following

• export docker images with docker save and load them back after upgrade with docker load.
• export containers with docker export command and restore them after upgrade with docker import.
• use a container to copy docker volume directories to the host. e.g. https://docs.docker.com/storage/volumes/#back-up-a-volume

Ability to seamlessly upgrade without loosing workload is being looked at, but there are no news yet.

Thanks for the fast answer (and sorry for replying so late ;-) )!

Okay I will manually save the data and move it to the new VM.

You should maybe add a note to the README that the colima delete will remove the VM and all the data within.
