Volumes mounted as read-only, is this intentional?

[nathanielks]

I was curious to see what sort of filesystem performance gains there were compared to Docker for Mac. I wanted to test a repo that would make a lot of filesystem writes, but in my tests I encountered an error saying the volume was mounted read-only. My apologies for my ignorance, but is this intentional? Should containers launched via lima with volumes be mounted as read-only volumes? For reference, here's how to reproduce:

cd path/to/somewhere
git clone [email protected]:withspectrum/spectrum.git
cd spectrum
lima nerdctl run -it --rm -v "$PWD":/usr/src/app -w /usr/src/app node:14 node shared/install-dependencies.js

This will eventually print the following error:

error Could not write file "/usr/src/app/yarn-error.log": "EROFS: read-only file system, open '/usr/src/app/yarn-error.log'"
error An unexpected error occurred: "EROFS: read-only file system, mkdir '/usr/src/app/node_modules'".

The docker analog that works ok:

docker run -it --rm -v "$PWD":/usr/src/app -w /usr/src/app node:14 node shared/install-dependencies.js

The home is read-only by default.

Aha, I missed that! Thank you 🙇

by default it is read only. to be make it writeable by default do the following:

• edit the file and set write: true under mount section

$ vim ~/.lima/default/lima.yaml

• then restart lima

limactl list #this lists all running vms 
limactl stop default #or name of the machine 
limactl start default #or name of the machine
