Hello World!

Welcome to the Hello World tutorial. In this short guide you will be able to :

  • Install and run the ClawIO Server Daemon (clawiod)
  • Install the ClawIO Controller (clawioctl) to interact with clawiod from a terminal

ClawIO Server Daemon

Download the latest release of clawiod for your platform, then extract and run it:

tar xvfz clawiod-*.tar.gz
cd clawiod-*

To start ClawIO, change to your clawiod build directory and run:

# By default, ClawIO stores data on your local filesystem
# at /tmp/clawio-namespace.
./clawiod

ClawIO should start running and will expose metrics at http://localhost:1502/metrics

ClawIO Controller

Download the latest release of clawioctl for your platform, then extract and run it:

tar xvfz clawioctl-*.tar.gz
cd clawioctl-*

To use the controller, change to your clawioctl build directory and run:

# By default, clawiod comes with an user called demo with password demo.
./clawioctl configure
Enter username (): demo
Enter password (******):
Enter authentication service base URL (http://localhost:1502/api/v1/authentication/):
Enter data service base URL (http://localhost:1502/api/v1/data/):
Enter metadata service base URL (http://localhost:1502/api/v1/metadata/):
Configuration saved to "/Users/labkode/.clawio/config"

Once the controller has been configured, we need to create our home directory.

./clawioctl metadata init
Home tree created!

Now we can list the contents of our home directory

./clawioctl metadata ls /
PATHSPEC  TYPE  SIZE MIMETYPE  CHECKSUM

At this point we do not have any data yet, so let's upload some files and create some folders

./clawioctl data upload ~/somefile.txt /somefile.txt
./clawioctl data upload ~/somefile.txt /somefile2.txt
./clawioctl data upload ~/somefile.txt /somefile3.txt
./clawioctl metadata mkdir /photos
./clawioctl data upload ~/myphoto.jpg /photos/myphoto.jpg

If we list again our home directory we will see the new added contents

./clawioctl metadata ls /
PATHSPEC       TYPE  SIZE  MIMETYPE                   CHECKSUM
photos         tree  102   clawio/tree
somefile.txt   blob  18    text/plain; charset=utf-8
somefile2.txt  blob  18    text/plain; charset=utf-8
somefile3.txt  blob  18    text/plain; charset=utf-8
