How to access EODATA and Object Storage using s3cmd on Linux on EO-Lab

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

Installation from your system repository on Debian/Ubuntu systems:

Check for updates:

$ sudo apt update

Install s3cmd:

$ sudo apt install s3cmd

Installation from the 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 it is 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

s3cmd configuration

Enter the following command:

$ s3cmd --configure

Enter new values or accept defaults in brackets with Enter.

Refer to the user manual for detailed description of all options.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty to use the environment 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 [eodata.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: eodata.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 How to generate and manage EC2 credentials on EO-Lab.

After the creation of credentials please remove the file .s3cfg from your Home folder and then reconfigure s3cmd by entering:

s3cmd --configure

and the following values:

New settings:
Access Key: (your EC2 credentials)
Secret Key: (your EC2 credentials)
Default Region: none
S3 Endpoint: s3.fra1-1.cloudferro.com
DNS-style bucket+hostname:port template for accessing a bucket: s3.fra1-1.cloudferro.com
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.
