bucketserver's Introduction

BucketServer

Serve GCS Bucket content anonymously

Serves a private bucket on Google Cloud Storage for anonymouse users by redirecting to a signed url of an object. A key file for a service user needs to be created. BucketServer will bind the specified port to all IP addresses on the local node. Please make sure you do not serve your private bucket to an unintended network. For example a VM on GCP with an external address might lead to serving the private bucket to the internet.

# Install BucketServer
go get -u -v github.com/google/BucketServer
# Create a service account
$AccountName = 'bucketserver-sa'
gcloud iam service-accounts create $AccountName --display-name "Service account for BucketServer"
# Get the Email of the service account
$Email = (gcloud iam service-accounts list --filter "EMAIL:($AccountName@*)")[1].Split() | Select-Object -Last 1
# Create a key JSON file for this service account
gcloud iam service-accounts keys create key.json --iam-account $Email
# Get a unique bucket name
$BucketName = [System.Guid]::NewGuid()
# Create the bucket
gsutil mb -c regional -l europe-west4 gs://$BucketName
# Grant read access to the service account
gsutil iam ch -e '' -d serviceAccount:$($Email):objectViewer gs://$BucketName
# Copy File to bucket
Get-Date > t.txt
gsutil cp t.txt gs://$BucketName
# Run BucketServer
$key = Get-Childitem key.json
$job = Start-Job -ScriptBlock {  &"$ENV:GOPATH\bin\BucketServer" $Args[0] $Args[1] $Args[2] } -ArgumentList @($BucketName, $key.Fullname, "8080")
