A Clojure library for loading gcloud credentials from an environment variable instead of a .json file.
When interoping with the Google SDK the initialization process is more or less as follows:
- Load credentials from file
- Initialize credentials
- Initialize the SDK by passing the credentials to it.
- Access resource in the Google cloud
This library allows the credentials to be loaded from the environment variable:
You can also load the credentials from a custom environment variable. I've found this really useful when deploying applications or running CI/CD outside the Google cloud.
You still need to perform steps 2 - 4 to get up and running.
(The dash in the package name creates problems)
- Get the
jsonfile containing your service account creditials by following the instruction here https://cloud.google.com/docs/authentication/getting-started
- Copy the contents of your
.jsoninto the GOOGLE_APPLICATION_CREDENTIALS environment variable. In your
~/.bash_profileand in Travis CI you should escape your credentials using singe quotes (
(require '[googlecredentials.core :as g-cred]) ;; By default load from GOOGLE_APPLICATION_CREDENTIALS (-> (. StorageOptions newBuilder) (.setCredentials (g-cred/load-service-credentials)) (.build) (.getService)) ;; Load from custom environment variable (def firebase-options (-> (new FirebaseOptions$Builder) (.setCredentials (g-cred/load-service-credentials :firebase-config)) (.build)) (.initializeApp FirebaseApp firebase-options) ;; Load from custom environment variable as string (def firebase-options (-> (new FirebaseOptions$Builder) (.setCredentials (g-cred/load-service-credentials "FIREBASE_CONFIG")) (.build)) (.initializeApp FirebaseApp firebase-options) ;; generic example (def cred (-> (<options-builder>) (.setCredentials (g-cred/load-service-credentials)) (.build)) (<cloud-library>/<initialisation-function> cred)
