构建包含Firebase凭证文件.json的golang

Question

I've written an Golang program designed to is parse a scv file and upload data to FireStore, this program was build to share with people who just write scv path to upload info.

I'm using this to use firebase-admin:

opt := option.WithCredentialsFile("path/to/serviceAccountKey.json")

This approach works fine when I do:

$ go run main.go

but when I build the project and execute the binary I got this:

$ cannot read credentials file: open firebase-config.json: no such file or directory 

I did read this approach but it means share firebase-config.json too, the idea of this Go program is just share the executable without any doc else.

Is there a way to build the program including the json or authenticate firebase-admin using json directly like this?:

opt := option.WithCredentials({< authentication json >})

I have no found documentation or examples using this method WithCredential.

I don't know if this is the best way to solve this but this is the way I did it:

1. I decided to place this script executable into /opt/< dir-name >/bin
2. I wrote an extra function which creates the auth .json /opt/< dir-name >/auth.json
3. All the script executes using this /opt/< dir-name >/auth.json file
4. I write another func which deletes the auth.json when the execution ends

So, now I can do this:

var file string = "/opt/< dir-name >/auth.json" 
sa := option.WithCredentialsFile(file)

Now I can share this script with the directive "Install into /opt/< dir-name>/bin and add this to your $PATH"
