How to access EO DATA using s3cmd (Linux)

You can install the s3cmd using Python PIP or from Linux repository.

Installation from system repository on Debian/Ubuntu systems:

Check for updates:
 

$ sudo apt update

Installing from repository:
 

$ sudo apt install s3cmd

Installation from Python repository (on most Linux distributions with python and pip preinstalled):

Installing with PIP:

Check if you have PIP installed

$ pip

The program 'pip' is currently not installed. To run 'pip' please ask your administrator to install the package 'python-pip'

If not installed (Ubuntu):

$ sudo apt install python-pip

$ pip --version

pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)

$ sudo pip install s3cmd

If you see the following:

Traceback (most recent call last):

File "/usr/bin/pip", line 11, in <module>

sys.exit(main())

File "/usr/lib/python2.7/dist-packages/pip/init.py", line 215, in main

locale.setlocale(locale.LC_ALL, '')

File "/usr/lib/python2.7/locale.py", line 581, in setlocale

return _setlocale(category, locale)

locale.Error: unsupported locale setting

add the following line:

export LC_ALL=en_US.UTF-8

to the file:

~/.profile

Now you can check the .profile:

$ cat ~/.profile

export LC_ALL=en_US.UTF-8

$ source ~/.profile

$ s3cmd --version

s3cmd version 2.0.1

Configure s3cmd
 

$ s3cmd --configure

Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
 

Access Key [access]:<ENTER>

Secret Key [access]:<ENTER>


Default Region [RegionOne]: <ENTER>


Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.

S3 Endpoint [data.cloudferro.com:] <ENTER>


Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used


if the target S3 system supports dns based buckets.

DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]:  <ENTER>


Encryption password is used to protect your files from reading

by unauthorized persons while in transfer to S3

Encryption password: <ENTER>

Path to GPG program [/usr/bin/gpg]: <ENTER>


When using secure HTTPS protocol all communication with Amazon S3

servers is protected from 3rd party eavesdropping. This method is

slower than plain HTTP, and can only be proxied with Python 2.7 or newer

Use HTTPS protocol [No]: <ENTER>


On some networks all internet access must go through a HTTP proxy.

Try setting it here if you can't connect to S3 directly

HTTP Proxy server name: <ENTER>


New settings:

   Access Key: access

   Secret Key: access

   Default Region: RegionOne

   S3 Endpoint: data.cloudferro.com

   DNS-style bucket+hostname:port template for accessing a bucket: %(bucket)s.s3.amazonaws.com

   Encryption password:

   Path to GPG program: /usr/bin/gpg

   Use HTTPS protocol: False

   HTTP Proxy server name: _____

   HTTP Proxy server port: 0


 Test access with supplied credentials? [Y/n] <ENTER>

 Please wait, attempting to list all buckets...

 Success. Your access key and secret key worked fine :-)


 Now verifying that encryption works...

 Not configured. Never mind.


 Save settings? [y/N]  y <ENTER>

 Configuration saved to '/home/eouser/.s3cfg'

Now you can use s3cmd commands (additional information about s3cmd: http://s3tools.org/usage)
 

$ s3cmd ls

2017-12-11 15:30  s3://DIAS

2017-12-11 15:30  s3://EOCLOUD

2017-12-11 15:30  s3://EODATA


$ s3cmd ls s3://EODATA/

                       DIR   s3://EODATA/Envisat/

                       DIR   s3://EODATA/Landsat-5/

                       DIR   s3://EODATA/Landsat-7/

                       DIR   s3://EODATA/Landsat-8/

                       DIR   s3://EODATA/Sentinel-1/

                       DIR   s3://EODATA/Sentinel-2/

                       DIR   s3://EODATA/Sentinel-3/

                       DIR   s3://EODATA/Sentinel-5P/

In order to acquire access to Object Storage buckets via s3cmd, first you have to generate your own ec2 credentials with this tutorial.
After creation of credentials please remove file .s3cfg in Home folder and then reconfigure s3cmd by entering:

s3cmd --configure 

and following values:

New settings:
Access Key: (your EC2 credentials)
Secret Key: (your EC2 credentials)
Default Region: none
S3 Endpoint: cf2.cloudferro.com:8080
DNS-style bucket+hostname:port template for accessing a bucket: cf2.cloudferro.com:8080
Encryption password: (your password)
Path to GPG program: /usr/bin/gpg
Use HTTPS protocol: True
HTTP Proxy server name:
HTTP Proxy server port: 0

After this operation, you should be allowed to list and access your Object Storage.
