问题描述
限时送ChatGPT账号..我正在设置 Docker 容器.
I'm setting up Docker containers.
在服务器端，文件上传到 S3.
On the server side, files are uploaded to S3.
在我本地环境下上传成功.
It succeeded to upload under my local environment.
但是在Docker环境下上传失败.
However, it fails to upload under Docker environment.
客户端:React/axios服务器:Golang/gin数据库:mysql源代码:https://github/jpskgc/articlearticle
├ client
├ api
└ docker-compose.yml
这里是 docker-compose.yml:
Here is the docker-compose.yml:
version: '3'
services:
api:
build:
dockerfile: Dockerfile.dev
context: ./api
volumes:
- ./api:/app
ports:
- 2345:2345
depends_on:
- db
tty: true
volumes:
- $HOME/.aws/credentials.properties:/home/api/.aws/credentials.properties
这是访问 S3 的服务器端代码.
Here is the server side code to access to S3.
api := router.Group("/api")
{
api.POST("/post/image", func(c *gin.Context) {
var creds *credentials.Credentials
var err error
creds = credentials.NewSharedCredentials("", "default")
_, err = creds.Get()
if err != nil {
creds = credentials.NewCredentials(&ec2rolecreds.EC2RoleProvider{})
_, err = creds.Get()
}
cfg := aws.NewConfig().WithRegion("ap-northeast-1").WithCredentials(creds)
svc := s3.New(session.New(), cfg)
form, _ := c.MultipartForm()
files := form.File["images[]"]
var imageNames []ImageName
imageName := ImageName{}
for _, file := range files {
f, err := file.Open()
if err != nil {
log.Println(err)
}
defer f.Close()
size := file.Size
buffer := make([]byte, size)
f.Read(buffer)
fileBytes := bytes.NewReader(buffer)
fileType := http.DetectContentType(buffer)
path := "/media/" + file.Filename
params := &s3.PutObjectInput{
Bucket: aws.String("article-s3-jpskgc"),
Key: aws.String(path),
Body: fileBytes,
ContentLength: aws.Int64(size),
ContentType: aws.String(fileType),
}
resp, err := svc.PutObject(params)
fmt.Printf("response %s", awsutil.StringValue(resp))
imageName.NAME = file.Filename
imageNames = append(imageNames, imageName)
}
c.JSON(http.StatusOK, imageNames)
})
}
我希望图像在服务器端上传到 S3.
I expect images are uploaded in server side to S3.
但实际上并非如此.

推荐答案
我在 docker-compose.yml 中设置环境变量并在控制台中设置值.
I set environment variable in docker-compose.yml and set value in console.
environment:
- AWS_ACCESS_KEY_ID
- AWS_SECRET_ACCESS_KEY
$ export AWS_ACCESS_KEY_ID=$(aws --profile default configure get aws_access_key_id)
$ export AWS_SECRET_ACCESS_KEY=$(aws --profile default configure get aws_secret_access_key)
creds := credentials.NewStaticCredentials(os.Getenv("AWS_ACCESS_KEY_ID"), os.Getenv("AWS_SECRET_ACCESS_KEY"), "")
