Increase RAM of existing container

[dmbr0]

I am trying to increase the ram of an existing container. I have tried this from another post:

docker update --memoryswap=8g --memory=8g containerID

but it returns:

unknown flag: --memoryswap See 'docker update --help'.

does anyone know a way to do this?

[dmbr0]

Edit launch.sh and change RAM

docker update --memory=8g --memoryswap=8g containerID
