Install the Minio implementation:

go get

And then run minio on Docker

docker run -d --restart always -p 9000:9000 -p 9001:9001 --name storage-minio --volume=minio:/var/lib/minio -e MINIO_ROOT_USER='minio-user' -e MINIO_ROOT_PASSWORD='minio-password' minio/minio server --console-address ":9001" /var/lib/minio


Import the storage package.

import ""

You can use the following possibilities to create a storage:

// Initialize default config
store := minio.New()

// Initialize custom config
store := minio.New(minio.Config{
Bucket: "fiber-bucket",
Endpoint: "localhost:9000",
Credentials: Credentials{
AccessKeyID: "minio-user",
SecretAccessKey: "minio-password",


// Config defines the config for storage.
type Config struct {
// Bucket
// Default fiber-bucket
Bucket string

// Endpoint is a host name or an IP address
Endpoint string

// Region Set this value to override region cache
// Optional
Region string

// Token Set this value to provide x-amz-security-token (AWS S3 specific)
// Optional, Default is false
Token string

// Secure If set to true, https is used instead of http.
// Default is false
Secure bool

// Reset clears any existing keys in existing Bucket
// Optional. Default is false
Reset bool

// Credentials Minio access key and Minio secret key.
// Need to be defined
Credentials Credentials

// GetObjectOptions Options for GET requests specifying additional options like encryption, If-Match
GetObjectOptions minio.GetObjectOptions

// PutObjectOptions
// Allows user to set optional custom metadata, content headers, encryption keys and number of threads for multipart upload operation.
PutObjectOptions minio.PutObjectOptions

// ListObjectsOptions Options per to list objects
ListObjectsOptions minio.ListObjectsOptions

// RemoveObjectOptions Allows user to set options
RemoveObjectOptions minio.RemoveObjectOptions

Default Config

The default configuration lacks Bucket, Region, and Endpoint which are all required and must be overwritten:

// ConfigDefault is the default config
var ConfigDefault = Config{
Bucket: "fiber-bucket",
Endpoint: "",
Region: "",
Token: "",
Secure: false,
Reset: false,
Credentials: Credentials{},
GetObjectOptions: minio.GetObjectOptions{},
PutObjectOptions: minio.PutObjectOptions{},
ListObjectsOptions: minio.ListObjectsOptions{},
RemoveObjectOptions: minio.RemoveObjectOptions{},
type Credentials struct {
AccessKeyID string
SecretAccessKey string
