Arc Google Cloud Storage
Arc GCS Provides an Arc
storage back-end for Google Cloud Storage
.
Please note as Arc has not been updated or activly maintained we are now switching over to Waffle
Installation
Add the latest stable release to your mix.exs
file:
defp deps do
[
{:arc_gcs, "~> 0.2"}
]
end
Then run mix deps.get
in your shell to fetch the dependencies.
Configuration
config :arc,
storage: Arc.Storage.GCS,
bucket: "gcs-bucket-name"
config :goth,
json: "/path/to/json" |> Path.expand |> File.read!
Custom Token Generation
By default, the credentials provided to Goth will be used to generate tokens. If you have multiple sets of credentials in Goth or otherwise need more control over token generation, you can define your own module:
defmodule MyCredentials do
@behaviour Arc.Storage.GCS.TokenFetcher
@impl Arc.Storage.GCS.TokenFetcher
def get_token(scopes) when is_list(scopes), do: get_token(Enum.join(scopes, " "))
@impl Arc.Storage.GCS.TokenFetcher
def get_token(scope) when is_binary(scope) do
{:ok, token} = Goth.Token.for_scope({"my-user@my-gcs-account.com", scope})
token.token
end
end
And configure it to use this new module instead of the default token generation:
config :arc,
storage: Arc.Storage.GCS,
bucket: "gcs-bucket-name",
token_fetcher: MyCredentials
Tests
To run the tests you need to set the following
ARC_TEST_BUCKET
- e.ggcs-bucket-name
GOOGLE_CREDENTIAL
- your JSON credential from Google- Finally
mix test
