Is it possible to increase ram after creating the container?

[w84death]

I got here with the same problem. I have 32GB to use and the container only senses 2GB.

I'll write a script later today

[sickcodes]

The easiest way would be docker start -ai yourcontainer

docker exec -it containerid /bin/bash

vi Launch.sh

And add RAM=16 for 16GB of ram at the top of the script

[sickcodes]

The correct solution is: https://github.com/sickcodes/Docker-OSX#quick-start-own-image-naked-container-image

[avijoni]

docker update --memory=16g container-name

[sickcodes]

docker update --memory=16g container-name

Woah didn't even know you could do Docker update!

[avijoni]

Btw, don't forget to expand swap space. I had issue adding more ram, without adding more swap space. Swap should be at least the size of memory. Hope this helps.

docker update --memory=4g --memory-swap=4g container-name

you can put --memory-swap=-1 for unlimited

Cheers.

im tryng to change ram memory but no luck
i changed the launch.sh and the docker ram, but macos does not recognize more than 4gb of ram (my windows pc is 32gb and wsl gives full access to windows ram, does not limit)
can you help me where exactly i change to recognize more ram in macos?
more info: im running docker-osx:ventura
I would like to use macos ventura to study development on xcode

Having the same problem.
EDIT:
Recreated the container with RAM=16

How were you able to change the ram on it??

I had the most success following this:

The easiest way would be docker start -ai yourcontainer

docker exec -it containerid /bin/bash

vi Launch.sh

And add RAM=16 for 16GB of ram at the top of the script

When adding more cpu I had to add the following to lines in the beginning of Launch.sh like this:

CORES=8
SMP=8

Just adding CORES does not work and the container exits immediately after starting.

Realmente tive sucesso aqui. muito obrigada. Depois de 3 dias tentando consequi agora.

I really had success here. thank you very much. After 3 days of trying I got it now.

[antoniovini47]

Thanks, that worked! Just need to restart the container after that.

[mateusdata]

Perfeito.

[dannypurcell]

Brilliant, Thanks!

Confirming this works, just went through the following:

• Set up a Sonoma image according to the README
• Run docker update --memory=4g --memory-swap=4g <container-name>
• docker exec -it <container-name> /bin/bash
• Make the top of file edits as shown in the screenshot here, save and exit vi
• Shutdown from OSX Apple menu
• docker restart <container-name>

Now able to run XCode Simulator to run on a Sonoma 14.7.2 image
