======The Cumulocity agent in LXC Container ======
====Create a new LXC Container====
First you have to create e new container. To do this please follow this:

[[http://wiki.netmodule.com/app-notes/virtualisation?s[]=lxc|LXC Virtualization]]
====Generate a new SSH public key====
We need for the agent SSH. We create the key in the lxc container.
<code bash>
ssh-keygen
#The new key
cat /root/.ssh/id_rsa.pub
#cp the key and go to the router and copy the key in this file
vi /etc/dropbear/authorized_keys
</code>
====Build the agent====
Now we need to make some installation.
<code bash>
#g++
apt-get install g++
#curl and libcurl
apt-get install libcurl3-dev & apt-get install curl
#make for Makefile
apt-get install make
</code>
Download the Cumulocity C/C++ SDK:
<code bash>wget https://bitbucket.org/m2m/cumulocity-sdk-c/get/d627781f3afa.zip
unzip d627781f3afa.zip
cd m2m-cumulocity-sdk-c-d627781f3afa
</code>
Create an init.mk file, and define specific macros CPPFLAGS, CXXFLAGS and LDFLAGS, LDLIBS and CXX for compiling.
<code bash>
CXX:=/usr/bin/g++
CPPFLAGS:=-I/usr/include
CXXFLAGS:=-Wall -pedantic -Wextra
LDFLAGS:=-L/usr/lib
LDLIBS:=-lcurl
</code>
If you have defined init.mk now you have to create the makefile.
<code bash>
cp Makefile.template Makefile
</code>
Add the Cumulocity agent to the SDK:{{:app-notes:netmodulecumulocityagentlxc.tar.gz|}}
<code bash>
tar -xvzf netmodulecumulocityagentlxc.tar.gz
cd netmoduleCumulocityAgentLXC
</code>
Move the content of **src** folder to the **src** folders of the SDK.
<code bash>
cp src/* sdk_folder/src/
#Copy also the srtemplate.txt
cp srtemplate.txt sdk_folder/src/
</code>
Edit the configfile (c8yAgent.conf) and move it.
<code bash>
cp c8yAgent.conf /etc/
</code>
Now we can build the agent.
<code bash>
make

#If you want, you can delete all and rebuild again:
make clean
make
</code>
Now go to the **src** folder.
<code bash>
make
chmod 775 -R main
</code>
<code bash>
./main
</code>
