Feature/image service

[bookpanda]

• Add build package workflow
• imageService: FindByPetId, Upload, AssignPet, Delete

Business Logic

image.FindByPetId(): finds images of that pet

image.Upload(): uploads to S3 and create a row with url of that S3 (empty foreign key)
If upload has field petId, then it create the row with petId (have foreign key)

image.AssignPet(): assigns row with specified url with that pet id (add foreign key)

image.Delete(): deletes row and object in S3

When creating pet

For image upload, keep the url from response, imageService.Upload(file) returns Image

For pet create, attach images’ urls into the POST request, petService.Create(pet + urls) ==calls==> imageService.AssignPet(urls, petId)

If delete image, imageService.Delete(id)

When updating pet

If delete image -> imageService.Delete(id) (image id got from petService.FindOne() fetched by client)

If upload image -> imageSrv.Upload(petId)

How to connect S3 bucket

make an AWS account, make an S3 bucket in ap-southeast-1 region, name it anything and paste the name in config.yaml, make sure S3 bucket has public policy

Tests

(FindPetById, AssignPet needs to wait for johnjud-backend)

Upload

Delete

file's URL works

Hello, sorry for late notice. One question, don't we need any access key or secret key in order to manage our S3 bucket?

it's in ~/. aws/credentials of the local machine. The AWS SDK uses the key from that directory, no need to specify.
We will only use AWS as test, The prod bucket will not be AWS from what I've heard

[Nitiwat-owen]

If the prod bucket is not AWS, so we need to change our codes in the future right?

[bookpanda]

yes, but Tar said it is AWS-compatible, so I hope the code would stay the same.
