Install GCS FUSE in Google Cloud Container Optimized OS (COS)

Question

Could you please provide the commands to install gcsfuse in Google Cloud Container Optimized OS (COS) and mount a bucket? Also I'm not sure which would be recommended, doing it directly on OS or on the container.

I came across this command here

docker run --privileged -v /mnt/disks/bucket:/bucket --device /dev/fuse my_gcsfuse /go/bin/gcsfuse -o allow_other <BUCKET> /bucket

Is this the way to install and mount a bucket in Google Cloud Container Optimized OS (COS) at container level?

Answer 1

Here 4 options that you may want to consider:

1. running docker from within a container (aka DIND) on COS is perfectly possible as you did, but read the answer for the link you posted, you must add a flag for the mount to work e2e
2. DIND is not really installing. If you really want to install, you can refer to a hack I used to install docker-compose and follow the installation instructions for gcsfuse
3. you could use Cloud Run instead, and configure your my_gcsfuse (or use the latest official Dockerfile) as a sidecar container. Sidecar and main containers use shared volumes
4. if you use a custom image, merge both Dockerfiles - see the builder base image to copy the gcsfuse executable from - and use the new image to run on COS

The last option has my preference.

Answer 2

GCSFuse currently does not support Google Cloud Container Optimized OS (COS).
