* add minio-go dep, update deps * add minio s3 client minio has an s3 compatible api and is an open source project and, notably, is not amazon, so it seems best to use their client (fwiw the aws-sdk-go is a giant hair ball of things we don't need, too). it was pretty easy and seems to work, so rolling with it. also, minio is a totally feasible option for fn installs in prod / for demos / for local. * adds 's3' package for s3 compatible log storage api, for use with storing logs from calls and retrieving them. * removes DELETE /v1/apps/:app/calls/:call/log endpoint * removes internal log deletion api * changes the GetLog API to use an io.Reader, which is a backwards step atm due to the json api for logs, I have another branch lined up to make a plain text log API and this will be much more efficient (also want to gzip) * hooked up minio to the test suite and fixed up the test suite * add how to run minio docs and point fn at it docs some notes: notably we aren't cleaning up these logs. there is a ticket already to make a Mr. Clean who wakes up periodically and nukes old stuff, so am punting any api design around some kind of TTL deletion of logs. there are a lot of options really for Mr. Clean, we can notably defer to him when apps are deleted, too, so that app deletion is fast and then Mr. Clean will just clean them up later (seems like a good option). have not tested against BMC object store, which has an s3 compatible API. but in theory it 'just works' (the reason for doing this). in any event, that's part of the service land to figure out. closes #481 closes #473 * add log not found error to minio land

Minio Go Client SDK for Amazon S3 Compatible Cloud Storage

The Minio Go Client SDK provides simple APIs to access any Amazon S3 compatible object storage.
This quickstart guide will show you how to install the Minio client SDK, connect to Minio, and provide a walkthrough for a simple file uploader. For a complete list of APIs and examples, please take a look at the Go Client API Reference.
This document assumes that you have a working Go development environment.

Initialize Minio Client
Minio client requires the following four parameters specified to connect to an Amazon S3 compatible object storage.
| Parameter | Description |
|---|---|
| endpoint | URL to object storage service. |
| accessKeyID | Access key is the user ID that uniquely identifies your account. |
| secretAccessKey | Secret key is the password to your account. |
| secure | Set this value to 'true' to enable secure (HTTPS) access. |
package main
import (
"github.com/minio/minio-go"
"log"
)
func main() {
endpoint := "play.minio.io:9000"
accessKeyID := "Q3AM3UQ867SPQQA43P2F"
secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
useSSL := true
// Initialize minio client object.
minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
if err != nil {
log.Fatalln(err)
}
log.Printf("%#v\n", minioClient) // minioClient is now setup
}
Quick Start Example - File Uploader
This example program connects to an object storage server, creates a bucket and uploads a file to the bucket.
We will use the Minio server running at https://play.minio.io:9000 in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.

useSSL := true
// Initialize minio client object.
minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
if err != nil {

// Make a new bucket called mymusic.
bucketName := "mymusic"
location := "us-east-1"
err = minioClient.MakeBucket(bucketName, location)
if err != nil {
// Check to see if we already own this bucket (which happens if you run this twice)
exists, err := minioClient.BucketExists(bucketName)
if err == nil && exists {
log.Printf("We already own %s\n", bucketName)
} else {
log.Fatalln(err)
}
}
log.Printf("Successfully created %s\n", bucketName)
// Upload the zip file
objectName := "golden-oldies.zip"
filePath := "/tmp/golden-oldies.zip"
contentType := "application/zip"
// Upload the zip file with FPutObject
n, err := minioClient.FPutObject(bucketName, objectName, filePath, minio.PutObjectOptions{ContentType:contentType})
if err != nil {
log.Fatalln(err)
}
log.Printf("Successfully uploaded %s of size %d\n", objectName, n)
}
