GCS store Proxy

A minimal web app to serve static assets stored in Google Clould storage buckets via HTTP.

Rationale

I ended up writing this as I couldn't find a viable way to expose GCS objects via HTTP while at the same time enforcing authentication/authorisation. Hence I have resorted to writing a simple app to proxy HTTP requests to

Building and running

# Build the executable
cd main && go build . && cd .. && cp main/main gcs-proxy

# running supplying the configuration file as it's sole argument
./gcs-proxy config.toml

Configuration

The program expects a few mandatory configuration parameters to be supplied a .toml file. This is the expected file structure:

[Gcs]
# Full path to the GCP Service account credentials
ServiceAccountFilePath = "/etc/gcs-proxy-sa.json"

# A mapping from request path fragment to bucket name
Buckets = { "bucket1" = "loadballancer-test-bucket" }

[Web]
# The port the app will be listening to
Port = 9999
