Probably related commit: FIX: Use dualstack S3 endpoint for direct uploads (#29611) · discourse/discourse@0568d36 · GitHub

I use S3 object storage upload to DO Spaces. The issue is probably with this.

Configure an S3 compatible object storage provider for uploads

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
          - sudo -E -u discourse bundle exec rake s3:expire_missing_assets

Thanks

I commented out these lines which makes the rebuild run successfully but the site stuck on splash I think because cannot load assets. Safe mode same…

  after_assets_precompile:
    - exec:
        cd: $home
        cmd:
          - sudo -E -u discourse bundle exec rake s3:upload_assets
          - sudo -E -u discourse bundle exec rake s3:expire_missing_assets

Any idea? I know it’s a bad timing…

Hey Don, we’ll have a look. Thanks for reporting.

My rebuild with a Digital Ocean Spaces S3 setup started failing with this error:

Correctly ignore `use_dualstack_endpoint` when using custom service endpoint regardless of source of either setting

opened 06:43AM - 07 Jun 24 UTC

gdavison

bug

### Description The `use_dualstack_endpoint` parameter instructs the AWS SDK en…dpoint resolver to return a dual-stack endpoint. If a custom endpoint is configured for a service, the resolver returns an error. When a custom endpoint is supplied for a service, the value of `use_dualstack_endpoint` must be ignored. Test the following combinations: * Use dual-stack endpoint set on the provider, shared configuration file, or environment variable * No custom endpoint (returns default dual-stack endpoint), custom endpoint set on the provider, shared configuration file, or environment variable, base endpoint set in shared configuration file or environment variable (#32649 suggests adding base endpoint configuration on the provider) ### References See #37876 for the equivalent issue with FIPS endpoints ### Would you like to implement a fix? None

After 3.243.0 Host override cannot be combined with Dualstack, FIPS, or S3 Accelerate

guidance response-requested

### Describe the bug After the update to version 3.243.0 and I think the start …of using Aws\EndpointV2 it would appear that the option for `use_dual_stack_endpoint` and possibly `use_fips_endpoint` are always true. This prevents multipart uploads which use accelerator and any writes that use accelerator with possible other issues as a result. When tracing through the updates made in 3.243.0 and subsequent updates I was unable to determine where the options are actually being set to true, or if the default behavior for these options is being assumed as true on the AWS end and explicitly setting them to false is being ignored. I am using Laravel 9 with league/flysystem-aws-s3-v3 but the issue appears to be isolated with changes starting with aws-sdk-php v3.243.0 and later. Explicitly setting `"aws/aws-sdk-php": "3.242.1"` in composer resolves the issue ### Expected Behavior Default values for `use_dual_stack_endpoint` and `use_fips_endpoint` is false. Setting env variables `AWS_USE_DUAL_STACK_ENDPOINT` and `AWS_USE_FIPS_ENDPOINT` to false is respected. ### Current Behavior Default values for `use_dual_stack_endpoint` and `use_fips_endpoint` appears to be true. Setting env variables `AWS_USE_DUAL_STACK_ENDPOINT` and `AWS_USE_FIPS_ENDPOINT` to false is ignored. ### Reproduction Steps Create an S3 client with default Laravel S3 config and create a multipart upload ``` $client = Storage::disk('s3')->getClient(); $result = $client->createMultipartUpload([ 'Bucket' => $bucket, 'Key' => $key, 'ContentType' => $type, 'ContentDisposition' => 'inline', ]); ``` Results in error `Host override cannot be combined with Dualstack, FIPS, or S3 Accelerate` Environment variables used ``` AWS_ACCESS_KEY_ID=***** AWS_SECRET_ACCESS_KEY=***** AWS_DEFAULT_REGION=ca-central-1 AWS_BUCKET=my-bucket-name AWS_URL="https://s3.amazonaws.com" AWS_POST_END_POINT="https://${AWS_BUCKET}.s3.amazonaws.com/" AWS_USE_PATH_STYLE_ENDPOINT=false AWS_USE_ACCELERATE_ENDPOINT=true AWS_USE_DUAL_STACK_ENDPOINT=false AWS_USE_FIPS_ENDPOINT=false ``` ### Possible Solution _No response_ ### Additional Information/Context The specific error `Host override cannot be combined with Dualstack, FIPS, or S3 Accelerate` does not appear to be common but has recently been reported with aws cli on stackoverflow indicating it may actually result from a more recent change on AWS/S3 side of things. ### SDK version used 3.243.0 ### Environment details (Version of PHP (`php -v`)? OS name and version, etc.) php 8.0.12, laravel/framerwork ^9.0, league/flysystem-aws-s3-v3 ^3.0, aws/aws-sdk-php ^3.243.0

Maybe S3_REGION should be cleared if an endpoint is set here?

Strangely, that gives me this error:

Gem::LoadError: can't activate webrick-1.9.0, already activated webrick-1.8.2 (Gem::LoadError)

which I’d just seen on an instance I was using to run an import, which I “fixed” by upgrading.

I guess I just can’t upgrade this server right now.

Don · November 7, 2024, 7:48pm

I am not sure but maybe worth a try. I did a rebuild succesfully before do this.

And just after this try to rebuild with pick the commit. Second time run the rebuild successfully.

Falco · November 7, 2024, 8:14pm

@martin usually what we do here is providing a GlobalSetting to disable the behavior that people running incompatible S3 clones can then opt-in to make it work.

IMO, the current behavior should stay as the default, but provide toggles to increase compatibility.

See prior art in DISCOURSE_S3_HTTP_CONTINUE_TIMEOUT, DISCOURSE_S3_INSTALL_CORS_RULE, etc.

martin · November 8, 2024, 12:13am

Ah sorry my bad here everyone, these S3 clones always slip my mind. I actually had to fix this custom endpoint issue with Minio yesterday. I think the fix here can just to be never use dualstack if DISCOURSE_S3_ENDPOINT has been set since they are incompatible, and everyone here is seemingly using that.

Thanks for the quick fix! I’m back in business.

Thanks for the lucid explanation, Rafael!

That’s because there’s a lot of stuff to keep in mind! And the spec tests, I think, would require those annoying stub_requests which I know I hate writing.

FWIW, that sounds right to me. And you could probably write tests for that that didnt’ require stubs for stub_requests.

merefield · November 13, 2024, 11:29am

I don’t think this should be marked as fixed .

This change has very likely caused a break to backups on several instances (with others not knowing that their instances aren’t backing up yet presumably).

That suggests to me the specs are not broad enough to capture all the real use cases and changes are passing that shouldn’t have?

pfaffman · November 14, 2024, 5:01pm

It sounds to me like it is fixed just for sites that have use_s3 turned on but not those that are using S3 only for backups.

Though it is again possible to rebuild, it’s just that S3 backups are broken.
