无法将文件从谷歌云存储桶复制到 VM 实例

Question

I am trying to transfer file from cloud bucket to VM instance.

I connected to VM instance by SSH, And used gsutil code like this :

gsutil cp gs://[bucket name]/[file name] /home

and then error was occur

Copying gs://huji/final-project-deep-learning-19-tf.tar... OSError: Permission denied. GiB]

So I tried this command :

sudo gsutil cp gs://[bucket name]/[file name] /home

And then, downloading completed.

Copying gs://huji/final-project-deep-learning-19-tf.tar... | [1 files][ 1.7 GiB/ 1.7 GiB] 76.2 MiB/s

but I cannot find any files and the disk volume hasn't changed. Can anybody explain why this happens and how to copy files from cloud? thanks.

Answer 1

1. Create a service account link :

    gcloud iam service-accounts create transfer --description "transfer" --display-name "transfer"

2. Set up a new instance to run as a service account:

    gcloud compute instances create instance --service-account transfer@my-project.iam.gserviceaccount.com --scopes https://www.googleapis.com/auth/devstorage.full_control

For example, the scope for full access to Cloud Storage is https://www.googleapis.com/auth/devstorage.full_control . The alias for this scope is storage-full

3. SSH to the VM instance:

    gcloud beta compute --project "my-project" ssh --zone "us-central1-a" "instance"

4. Copy the files :

    gsutil cp gs://bucket/file.csv .

5. List the files:

    ls file.csv
