I just went over some common Object Storage providers so I can attest if they work or not with Discourse.
| Provider | Service Name | Works with Discourse? |
|---|---|---|
| Amazon AWS | S3 | Yes |
| Digital Ocean | Spaces | Yes |
| Linode | Object Storage | Yes |
| Google Cloud | Storage | Yes |
| Scaleway | Object Storage | Yes |
| Vultr | Object Storage | Yes |
| BackBlaze | Cloud Storage | Yes |
If you got a different service working, please add it to this wiki.
Configuration
In order to store Discourse static assets in your Object Storage add this configuration on your app.yml under the hooks section:
after_assets_precompile:
- exec:
cd: $home
cmd:
- sudo -E -u discourse bundle exec rake s3:upload_assets
When using object storage, you also need a CDN to serve what gets stored in the bucket. I used StackPath CDN in my testing, and other than needing to set Dynamic Caching By Header: Accept-Encoding in their configuration it works ok.
DISCOURSE_CDN_URL is a CDN that points to you Discourse hostname and caches requests. It will be used mainly for pullable assets: CSS and other theme assets.
DISCOURSE_S3_CDN_URL is a CDN that points to your object storage bucket and caches requests. It will be mainly used for pushable assets: JS, images and user uploads.
We recommend those being different and for admins to set both.
In the following examples https://falcoland-files-cdn.falco.dev is a CDN configured to serve the files under the bucket. The bucket name was set to falcoland-files in my examples.
AWS S3
What we officially support and use internally. Their CDN offering Cloudfront also works to front the bucket files.
In order to use it add this to the env section of your app.yml file, adjusting the values accordingly:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: us-west-1
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backups
DISCOURSE_BACKUP_LOCATION: s3
Digital Ocean Spaces
DO offering is good and works out of the box. Only problem is that their CDN offering is awfully broken, so you need to use a different CDN for the files.
Example configuration:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: whatever
DISCOURSE_S3_ENDPOINT: https://nyc3.digitaloceanspaces.com
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backups
DISCOURSE_BACKUP_LOCATION: s3
Linode Object Storage
An extra configuration parameter, HTTP_CONTINUE_TIMEOUT, is required for Linode.
Example configuration:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: us-east-1
DISCOURSE_S3_HTTP_CONTINUE_TIMEOUT: 0
DISCOURSE_S3_ENDPOINT: https://us-east-1.linodeobjects.com
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backup
DISCOURSE_BACKUP_LOCATION: s3
GCP Storage
Listing files is broken, so you need an extra ENV to skip that. Also skip CORS and configure it manually.
Example configuration:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: us-east1
DISCOURSE_S3_INSTALL_CORS_RULE: false
FORCE_S3_UPLOADS: 1
DISCOURSE_S3_ENDPOINT: https://storage.googleapis.com
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backup
DISCOURSE_BACKUP_LOCATION: s3
Scaleway Object Storage
Scaleway offering is also very good, and everything works fine.
Example configuration:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: fr-par
DISCOURSE_S3_ENDPOINT: https://s3.fr-par.scw.cloud
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backups
DISCOURSE_BACKUP_LOCATION: s3
Vultr Object Storage
An extra configuration parameter, HTTP_CONTINUE_TIMEOUT, is required for Vultr.
Example configuration:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: whatever
DISCOURSE_S3_HTTP_CONTINUE_TIMEOUT: 0
DISCOURSE_S3_ENDPOINT: https://ewr1.vultrobjects.com
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backup
DISCOURSE_BACKUP_LOCATION: s3
Backblaze B2 Cloud Storage
You need to skip CORS and configure it manually.
Example configuration:
DISCOURSE_USE_S3: true
DISCOURSE_S3_REGION: "us-west-002"
DISCOURSE_S3_INSTALL_CORS_RULE: false
DISCOURSE_S3_CONFIGURE_TOMBSTONE_POLICY: false
DISCOURSE_S3_ENDPOINT: https://s3.us-west-002.backblazeb2.com
DISCOURSE_S3_ACCESS_KEY_ID: myaccesskey
DISCOURSE_S3_SECRET_ACCESS_KEY: mysecretkey
DISCOURSE_S3_CDN_URL: https://falcoland-files-cdn.falco.dev
DISCOURSE_S3_BUCKET: falcoland-files
DISCOURSE_S3_BACKUP_BUCKET: falcoland-files/backup
DISCOURSE_BACKUP_LOCATION: s3
