How would I set that? I tried looking in the docs and couldnt find anything about it other than it saying the containers automatically choose a location.

it's there in the API. I'm not sure how to do it in wrangler, maybe look here for clues? https://github.com/cloudflare/workers-sdk/blob/9c5601a7f5dc11869bf29fe5b4cb5c4558a75951/packages/workers-utils/src/config/environment.ts#L192

                }
            ],

this is my config. i ran a deploy but the container still says the last location it was in, which isn't in the region i specified. I also get a warning in the wrangler config saying: Property constraints is not allowed

Wrangler also doesnt show the edit in the list of applied changes it shows when deploying

edit: seems i had to delete the container completely to get it to start in the right location

Minori•11/1/25, 9:43 AM

so I was thinking of being able to use Containers as a backend for our game servers, so let's say our matchmaking code that runs on workers or DO, we wanna spawn a gameserver that remains as long as the session is active or there's players in it, is that possible?

<@235148962103951360>OP•11/1/25, 10:04 AM

it is possible to an extent

<@235148962103951360>OP•11/1/25, 10:04 AM

as far as i know, the containers dont expose ports and arent really accessible publicly

<@235148962103951360>OP•11/1/25, 10:04 AM

however, there are ways around it such as using playit.gg or an ssh tunnel to a machine/instance that is able to expose the ports etc

<@235148962103951360>OP•11/1/25, 10:05 AM

i have run a minecraft server with containers and it works

<@235148962103951360>OP•11/1/25, 10:05 AM

disk is ephemeral, so youll have to backup/restore game server data/files

We really don't mind the ephemeral nature of Containers as these instances are meant to elastically spin up and down so their player progress is stored elsewhere

<@235148962103951360>OP•11/1/25, 10:07 AM

the only thing is just exposing your game server

<@235148962103951360>OP•11/1/25, 10:07 AM

playit.gg or an ssh tunnel are 2 of the options

Minori•11/1/25, 10:07 AM

<@235148962103951360>OP•11/1/25, 10:08 AM

have a look at this it should give u an idea of how you could do it

<@235148962103951360>OP•11/1/25, 10:08 AM

the only issue is the instance specs

<@235148962103951360>OP•11/1/25, 10:09 AM

you need an enterprise plan to customise them i believe, or ur stuck with the default presets which arent exactly ideal for game servers e.g. 1/2 vcpu and 4gb ram for minecraft for example isnt great. the ram is ok for a small survival sever but 1/2 cpus is too weak

<@235148962103951360>OP•11/1/25, 10:09 AM

i tried with 1/2 cpu/4gb and loading chunks took a while

Minori•11/1/25, 10:09 AM

I really wish they have better instances icl

<@235148962103951360>OP•11/1/25, 10:09 AM

and the server was constantly behind

<@235148962103951360>OP•11/1/25, 10:10 AM

there are higher ones

<@235148962103951360>OP•11/1/25, 10:10 AM

but the specs arent suited for minecaft at least. maybe its ok for some other games

Minori•11/1/25, 10:10 AM

We do have the option of integrating Steam's Networking Relay if we can't expose the gameserver ports directly

Minori•11/1/25, 10:10 AM

I have to check how much Unreal's dedicated servers eat and go from there

<@235148962103951360>OP•11/1/25, 10:10 AM

do you plan to make your own game

<@235148962103951360>OP•11/1/25, 10:10 AM

that could work yeah

<@235148962103951360>OP•11/1/25, 10:10 AM

<@235148962103951360>OP•11/1/25, 10:10 AM

these are the available instance types

<@235148962103951360>OP•11/1/25, 10:11 AM

i believe enterprise can customise it

<@235148962103951360>OP•11/1/25, 10:11 AM

Do containers retain the process's memory or flush them constantly?

AAnon Do containers retain the process's memory or flush them constantly?

Isaac McFadyen•11/1/25, 4:01 PM

They retain it for the lifetime of the container.

Isaac McFadyen•11/1/25, 4:02 PM

When the container is shut down the memory goes with it though, the same as you'd have on e.g. Docker

How would I set that? I tried looking in the docs and couldnt find anything about it other than it s
