cmd/go-cache-plugin: custom s3 endpoint url #14
Conversation
There was a problem hiding this comment.
This change seems fine, but we should also update the documentation in help.go, and I have a few other small comments inline.
Can you please also update the commit title and description to provide more context for what this is doing? We also don't use the conventional-commits type tags like "feat" for PR titles.
A suggestion for example:
cmd/go-cache-plugin: add support for a custom S3 endpoint URL
This allows use of other S3-compatible implementations for cache storage.
or words to that effect.

I think this flag needs a more descriptive name. Perhaps:
| S3URL string `flag:"s3-url,default=$GOCACHE_S3_URL,S3 URL"` | |
| S3Endpoint string `flag:"s3-endpoint-url,default=$GOCACHE_S3_ENDPOINT_URL,S3 custom endpoint URL (if unset, use AWS default)"` |
In particular: Make the name reflect that this is the endpoint URL, and note the meaning of the default.

Naming nit: Mixed case, please. I would just call this opts since there are no other options in scope here.

I suggest making this
| o.BaseEndpoint = &flags.S3URL | |
| o.BaseEndpoint = aws.String(flags.S3URL) |
The meaning is the same, but makes the intent clearer.

Oh, actually maybe a better way to do this is to add config.WithBaseEndpoint to the LoadDefaultConfig call, instead of here?

This is now tagged at and after v0.1.1. |
Allows to use custom endpoints that implement s3 API.
