Uploading a file to Atmos with Bash and Curl (and a little Python)

Here's an easy script to upload a file from bash using curl.  A small amount of Python is used here to compute the signature but you could substitue Perl or openssl if Python is not available.  The sections underlined should be modified to meet your local settings:

 

# Set up uid, key, and endpoint

uid="0206f43cfbb54e9099ee8de1ec77cf19/test1"

key="O4JmllPlIoqXPxcfWhrGV1TG2Y0="

endpoint="http://10.242.25.63"

# Choose the file to upload

file_to_upload=/etc/hosts

# Choose the Atmos directory to upload the file

atmos_dir="/share/"

# Build and send the Atmos request

filename=`basename $file_to_upload`

atmos_path="/rest/namespace${atmos_dir}$filename"

contentType="text/plain"

date=`date -u +"%a, %d %b %Y %H:%M:%S GMT"`

signstr="POST\n${contentType}\n\n\n${atmos_path}\nx-emc-date:${date}\nx-emc-uid:${uid}"

sig=$(python -c "import base64, hmac, sha; print base64.b64encode(hmac.new(base64.b64decode(\"$key\"), \"$signstr\", sha).digest())")

curl -i -X POST -H "Content-Type:$contentType" -H "x-emc-date:$date" -H "x-emc-uid:$uid" -H "x-emc-signature:$sig" --data-binary @${file_to_upload} ${endpoint}${atmos_path}

When you run the script, you'll get a success or failure response from the server:

HTTP/1.1 201 Created

You can parse the location response header to get the object ID if required.
