<p class="MsoNormal"><span lang="EN-US" style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:#1F497D">When you play Tricircle, it’s important to know that Tricircle is the OpenStack API gateway to other OpenStack instances. In the Readme, Pod1,
Pod2 are two OpenStack instances, before trying Tricircle, you can make sure the environment is normal or not by executeing command separately on Pod1, Pod2, just Nova –os-region-name Pod1, or Nova –os-region-name Pod2, in fact, because Pod1,Pod2 are two
normal OpenStack instances, any command to Pod1,Pod2 should be successful. Otherwise that means there are some issue in the installation of the environment itself. Only when each bottom OpenStack can work correctly, then you can even manually add Tricircle,
or through the scripts in the github to install Tircircle automaticly, as the API gateway to Pod1 and Pod2, just like you add one load balancer before your multiple web servers.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:#1F497D">After the Tricircle was added, then the API will flow from Tricircle services like Nova-APIGW/Cinder-APIGW/Neutron API to the bottom Pod1, Pod2.<o:p></o:p></span></p>
