# Guide - Setup HedgeDoc S3 image upload to Google Cloud Storage
|
|
|
|
HedgeDoc has no direct/native support for storing images in Google Cloud Storage Buckets.
|
|
However since Google provides interoperability with S3, the S3 integration can be used.
|
|
|
|
This guide will help you in getting things setup.
|
|
|
|
## Setup the bucket
|
|
|
|
### Create a bucket in Google Cloud Storage
|
|
|
|
1. Create a new bucket [within the Cloud Storage portal](https://console.cloud.google.com/storage/browser).
|
|
2. Give it a name, select the region and type of storage (e.g. multi dual-region)
|
|
3. In "Choose how to control access to objects" disable "Enforce public access prevention on this bucket"
|
|
|
|
### Open the bucket to the public
|
|
|
|
In order to view the images uploaded to HedgeDoc the storage bucket needs to be set to public.
|
|
|
|
1. Click the bucket you just created in [the Cloud Storage portal](https://console.cloud.google.com/storage/browser).
|
|
2. Go to the Permissions tab
|
|
3. Scroll down to the Permissions section
|
|
4. Click Grant Access
|
|
5. Add `allusers` as principal
|
|
6. Give it role `Storage Object Viewer` to allow it to retrieve the roles
|
|
|
|
### Setup interoperability & create Service Account
|
|
|
|
1. Go to the [interoperability tab](https://console.cloud.google.com/storage/settings;tab=interoperability) in the Google Cloud Console
|
|
2. Scroll down to "Access keys for service accounts" and click on "Create a key for a service account"
|
|
3. Select "Create new account"
|
|
4. Give it a name, e.g. `hedgedoc`
|
|
5. Select the `Storage Object Creator` role and select Add IAM Condition
|
|
6. Give it a name, e.g. `Restrict to bucket`
|
|
7. In Condition Builder:
|
|
1. Condition type: Name
|
|
2. Operator: Starts With
|
|
3. Value: `projects/_/buckets/YOUR_BUCKET_NAME_HERE`
|
|
8. Skip the 3rd step (Grant users access to this service account)
|
|
9. Click done
|
|
10. Copy the Access Key and Secret to a text editor, we'll be using this later
|
|
|
|
### Add permissions
|
|
|
|
1. Go to [Roles](https://console.cloud.google.com/iam-admin/roles) within the IAM & Admin section in Google Cloud Console
|
|
2. Click Create Role
|
|
3. Give it a name (e.g. `Allow to view buckets`) and an id (e.g. `bucket-viewer`)
|
|
4. Click Add Permissions
|
|
5. In the filter (below the dropdown) type `storage.buckets.get`
|
|
6. Check the box in front of the `storage.buckets.get` entry, click Add.
|
|
7. Click Create
|
|
|
|
8. Go to [IAM & Admin](https://console.cloud.google.com/iam-admin/iam) section and go to the IAM page
|
|
9. Find the user we created in the previous step and edit it
|
|
10. Click "Add another role" and select the role we just created
|
|
11. Select the role we just created and select Add IAM Condition
|
|
12. Give it a name, e.g. `Restrict to bucket`
|
|
13. In Condition Builder:
|
|
1. Condition type: Name
|
|
2. Operator: Starts With
|
|
3. Value: `projects/_/buckets/YOUR_BUCKET_NAME_HERE`
|
|
14. Save it.
|
|
|
|
## Configure HedgeDoc
|
|
|
|
Set the following environment variables (or the [corresponding config.json values](/configuration/#amazon-s3)):
|
|
|
|
```env
|
|
CMD_IMAGE_UPLOAD_TYPE="s3"
|
|
CMD_S3_ENDPOINT="https://storage.googleapis.com"
|
|
CMD_S3_ACCESS_KEY_ID="GOOG1EXXXXXXXXXX"
|
|
CMD_S3_SECRET_ACCESS_KEY="XXXXXXXXXX"
|
|
CMD_S3_BUCKET="your-bucket-name"
|
|
```
|
|
|
|
The access key and secret key are the values you received when you enabled the interoperability feature.
|
|
|
|
After restarting HedgeDoc you should now be able to add images to your pages. |
