<div dir="ltr"><div><div><div>Hi,<br><br></div>Indeed, running the agent as a container requires giving the container many privileges : access to the host network, host PID namespace, bind mount /run/netns and the Open vSwitch socket. So it's pretty much equivalent to running the Skydive executable (that has no external dependency).<br>The analyzer does not need these privileges and can be started as a "regular" container.<br></div><br></div><div>To start the agent container, the command is :<br>docker run --privileged --net=host --pid=host -v
/var/run/openvswitch/db.sock:/var/run/openvswitch/db.sock -v
/var/run/netns:/host/run -e SKYDIVE_NETNS_RUN_PATH=/host/run skydive agent<br><br></div><div>Now, to answer your question, you can either :<br></div><div>- use environment variables by adding "-e SKYDIVE_AGENT_ANALYZERS=<a href="http://1.2.3.4:8082">1.2.3.4:8082</a>" to the previous command line.<br></div><div><br>- create the configuration file on the host (for instance /etc/skydive.yml) with a section :<br>agent:<br> analyzers: <a href="http://1.2.3.4:8082">1.2.3.4:8082</a><br>and bind mount it into the container agent by adding the parameter "-v /etc/skydive.yml:/etc/skydive.yml" to the previous command line.<br><br></div><div>One final hint, you could easily bootstrap an analyzer with elasticsearch (for graph and flows history) on your first node by using the docker-compose service provided in the Skydive repository in one command : "docker-compose up"<br></div><div><br></div><div>Regards,<br></div><div>Sylvain<br></div><div><br><div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Dec 6, 2016 at 11:19 AM, Kostya <span dir="ltr"><<a href="mailto:konstantin.dorfman@gmail.com" target="_blank">konstantin.dorfman@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello Akshay,<div>I'm recently new to the project, so take this with a grain of salt:</div><div><br></div><div>Running analyzer/agent in container gives to it same access to host's network stack as running skydive as a process.<br></div><div>Integration of skydive and openstack is about how to configure openstack, so that skydive agent will run automatically on every compute node and analyzer will run on controller.
