Uploading to S3 in 18 lines of Shell (used to upload builds for http://soltrader.net)

s3.sh

# You don't need Fog in Ruby or some other library to upload to S3 -- shell works perfectly fine
# This is how I upload my new Sol Trader builds (http://soltrader.net)
# Based on a modified script from here: http://tmont.com/blargh/2014/1/uploading-to-s3-in-bash

S3KEY="my aws key"
S3SECRET="my aws secret" # pass these in

function putS3
{
  path=$1
  file=$2
  aws_path=$3
  bucket='my-aws-bucket'
  date=$(date +"%a, %d %b %Y %T %z")
  acl="x-amz-acl:public-read"
  content_type='application/x-compressed-tar'
  string="PUT\n\n$content_type\n$date\n$acl\n/$bucket$aws_path$file"
  signature=$(echo -en "${string}" | openssl sha1 -hmac "${S3SECRET}" -binary | base64)
  curl -X PUT -T "$path/$file" \
    -H "Host: $bucket.s3.amazonaws.com" \
    -H "Date: $date" \
    -H "Content-Type: $content_type" \
    -H "$acl" \
    -H "Authorization: AWS ${S3KEY}:$signature" \
    "https://$bucket.s3.amazonaws.com$aws_path$file"
}

for file in "$path"/*; do
  putS3 "$path" "${file##*/}" "/path/on/s3/to/files/"
done

@malbin not yet as it's outside my use case - only uploading <100MB files.

Fair point though. When I have that requirement I'll write a wrapper to do it - "simplest thing that could work but no simpler" :)

If you like this, you may find bashmenot useful. Among other things, it includes GNU bash functions to work with S3.

Great. It will be good if you print usage or putting top comments about how to use the script.

Thanks. I ended up using this as a base for a little script that I find handy: https://github.com/matiaskorhonen/shells3

Wrote a shell script to list a bucket here: https://github.com/kaihendry/s3listing/blob/master/listing.sh Be great to get your feedback.

maybe you need to use

date=$(TZ=utc date -R") 

to have a correct date (I did, on an alternate provider using S3 API though)

Thanks for sharing !

Hey I am getting an error like this :

< ..Code>SignatureDoesNotMatch</ Code>
<..Message >The request signature we calculated does not match the signature you provided. Check your key and signing method.</ Message>

I have checked the keys are correct, is it something to do with the signature or "https://$bucket.s3.amazonaws.com$aws_path$file" format has changed?

I adjusted the script:

• Specify the objectName instead of the file:
• Output the HTTP Headers

Updated Version

#!/bin/bash

objectName=test.properties
file=/home/mdesales/dev/github/spring-cloud-config-publisher/src/test/resources/app/ctg-config-with-matrix-outputTypes/application.properties-test
bucket=publisher-********
resource="/${bucket}/${objectName}"
contentType="text/plain"
dateValue=`date -R`
stringToSign="PUT\n\n${contentType}\n${dateValue}\n${resource}"
s3Key=AK*******NQ
s3Secret=xZ******************dAc
signature=`echo -en ${stringToSign} | openssl sha1 -hmac ${s3Secret} -binary | base64`
curl -v -i -X PUT -T "${file}" \
          -H "Host: ${bucket}.s3.amazonaws.com" \
          -H "Date: ${dateValue}" \
          -H "Content-Type: ${contentType}" \
          -H "Authorization: AWS ${s3Key}:${signature}" \
          https://${bucket}.s3.amazonaws.com/${objectName}

Hi chrismdp,

I ran the same script in my environment it is giving out an error.
SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method.AKI*****************LQPUT

Can you please help me with that..
I am also trying to create a download shell script as well if you have any information regarding that do let me know.

Thanks In Advance.
:) 👍

bro @Boomser13, I was in the same boat. I was missing "#!/bin/bash" at the top of the script, it started working when I added it.
(sh and bash are different it seems, and sometimes when not specified it defaults to sh)

Updated to handle region codes and storage classes (acl and content type could also be parameterised):

#S3 parameters
S3KEY="my-key"
S3SECRET="my-secret"
S3BUCKET="my-bucket"
S3STORAGETYPE="STANDARD" #REDUCED_REDUNDANCY or STANDARD etc.
AWSREGION="s3-xxxxxx"

function putS3
{
  path=$1
  file=$2
  aws_path=$3
  bucket="${S3BUCKET}"
  date=$(date +"%a, %d %b %Y %T %z")
  acl="x-amz-acl:private"
  content_type="application/octet-stream"
  storage_type="x-amz-storage-class:${S3STORAGETYPE}"
  string="PUT\n\n$content_type\n$date\n$acl\n$storage_type\n/$bucket$aws_path$file"
  signature=$(echo -en "${string}" | openssl sha1 -hmac "${S3SECRET}" -binary | base64)
  curl -s -X PUT -T "$path/$file" \
    -H "Host: $bucket.${AWSREGION}.amazonaws.com" \
    -H "Date: $date" \
    -H "Content-Type: $content_type" \
    -H "$storage_type" \
    -H "$acl" \
    -H "Authorization: AWS ${S3KEY}:$signature" \
    "https://$bucket.${AWSREGION}.amazonaws.com$aws_path$file"
}

Extending @ORANGE-XFM response and following this docs
If executing this script from MacOS bash you need to set date like this
date=$(TZ=utc date +"%Y%m%dT%H%M%SZ")
in order to get rid of the bad date format errors

Hi.
I use your script, but got an error message :

The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.

Any of you guys got message like this?

cc: @chrismdp

There's a problem with the locale. It works fine with en_US.utf8 locale but doesn't work with other languages because of the date string. I think it's better if there's an LC_TIME=en_US.utf8 somewhere in the script.

is there anyone that knows where i can get shells ?

@miznokruge I guess you are using one of the new regions after January 30, 2014. From http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html

This latest signature version is supported in all regions and any new regions after January 30, 2014 will support only Signature Version 4. For more information, go to Authenticating Requests (AWS Signature Version 4) in the Amazon Simple Storage Service API Reference.

This script using V2 API version, so to use new regions after January 30, 2014 you will need support v4 standard.

How to configure this with wasabi ?

Stoked to come across this. We are using it to upload files from AIX servers, which doesn't support (read: admins won't install) the AWS cli and related stuff. Thanks!

My company is using rook for s3 storage. So I have different base URL for my bucket. "http://abc.rook.com" like this.
so if I create a new bucket with let say "piyush" and put some object inside "test" then my URL becomes like this "http://abc.rook.com/piyush/test/abc.txt". I am able to put object using s3api but not with above curl script.
Please suggest what change I need to do.

I have the same problem

The request signature we calculated does not match the signature you provided

How to fix that?

For those with root access, just install awscli and be happy doing that in only one line https://aws.amazon.com/getting-started/hands-on/backup-to-s3-cli/
