Agent installation and registration

Install docker

follow

https://docs.docker.com/engine/install/ubuntu/

Install required dependencies by Agent.
Code Block
sudo apt-get install jq


then download and install packages agent package from

https://github.com/open-horizon/anax/releases

...

https://open-horizon.github.io/docs/installing/advanced_man_install.html

to change

Code Block
/etc/default/horizon

like following

Code Block
ubuntu@ubuntu:~$ cat /etc/default/horizon
