Backblaze B2 Storage Adapter for Ghost

A Backblaze B2 storage adapter for Ghost version 4 (also compatiable with version 3.x).

Installation

git clone https://github.com/zaxbux/ghost-storage-b2.git
cd ghost-storage-b2; npm i
cd ..
cp -r ghost-storage-b2 ./content/adapters/storage/b2

Configuration

You will need to obtain or create app keys and create a bucket in your B2 Cloud Storage Account.

If your Ghost configuration file, add the B2 configuration options:

{
  // ...

  "storage": {
    "active": "b2",
    "b2": {
      "applicationKeyId": "",
      // See table below for all config values
    }
  }

  // ...
}

Alternatively, the B2 storage adapter can be configured with environment variables:

| JSON File Option | Environment Variable | Value | ------------------ | ----------------------- | ----- | applicationKeyId | B2_APPLICATION_KEY_ID | Your B2 application key ID. | applicationKey | B2_APPLICATION_KEY | Your B2 application key. | bucketId | B2_BUCKET_ID | Your B2 bucket's ID. | bucketName | B2_BUCKET_NAME | (optional) Your bucket's name. | pathPrefix | B2_PATH_PREFIX | (optional) The prefix to add to uploads. | downloadUrl | B2_DOWNLOAD_URL | (optional) Use a custom URL for downloading. (CDN, etc.)

Custom Domain

If you're using a custom domain instead of the default backblaze domain, e.g. with a CNAME pointing cdn.example.com to f001.backblazeb2.com, and your bucket name is my_bucket:

• Set downloadUrl to https://cdn.example.com/file/my_bucket

Debugging

To debug the storage adapter, set the DEBUG environment variable to ghost-storage-b2.
