Local Emulator for Google Cloud Storage

Google doesn't (yet) ship an emulator for the Cloud Storage API like they do for Cloud Datastore.

This is a stub emulator so you can run your tests and do local development without having to connect to the production Storage APIs.

THIS IS A WORK IN PROGRESS AND ONLY SUPPORTS A LIMITED SUBSET OF THE API

Inside the container instance, the value of the PORT environment variable always reflects the port to which requests are sent. It defaults to 8080. The directory used for the emulated storage is located under /storage in the container. In the following example the host's directory $(pwd)/cloudstorage will be bound to the emulated storage.

docker run -d \
  -p 8080:8080 \
  --name gcp-storage-emulator \
  -v "$(pwd)/cloudstorage":/storage \
  oittaa/gcp-storage-emulator

Example

Create a test file emulator-test.py.

python
from google.auth.credentials import AnonymousCredentials
from google.cloud import storage

BUCKET = "test-bucket"

client = storage.Client(
    credentials=AnonymousCredentials(),
    project="test",
)
bucket = client.bucket(BUCKET)
bucket = client.create_bucket(bucket)
blob = bucket.blob("blob1")
blob.upload_from_string("test1")
blob = bucket.blob("blob2")
blob.upload_from_string("test2")
for blob in bucket.list_blobs():
    content = blob.download_as_bytes()
    print("Blob [{}]: {}".format(blob.name, content))

Run the following commands to test the emulated storage.

bash
export STORAGE_EMULATOR_HOST=http://localhost:8080
python3 emulator-test.py
