Container Hands-On

<!--HTML--><p>This session will be done in a training, hands-on&nbsp;format, covering topics related to containers.</p> <p>Topics include:</p> <ul> <li>Container basics (usage, underlying technologies)</li> <li>Image management and optimizations</li> <li>Container clusters and orchestration</li> <li>Containerized application lifecycle with Helm</li> <li>Autodevops</li> </ul> <p>It is recommended to bring your own laptop to follow the different&nbsp;exercises. Please make sure you have docker (&gt;17.09) installed on your laptop, you&nbsp;can login to lxplus-cloud.cern.ch and that you have enough quota on your personal OpenStack project - minimum 2 instances, 4 cores.</p> <p>HANDS ON:&nbsp;<a href="http://clouddocs.web.cern.ch/clouddocs/aviator/docs/index.html">http://clouddocs.web.cern.ch/clouddocs/aviator/docs/index.html</a></p> <p>LIVE NOTES:&nbsp;<a href="https://hackmd.web.cern.ch/s/B1YFyMl5M">https://hackmd.web.cern.ch/s/B1YFyMl5M</a></p> <p>UPDATE: We're providing an alternative way to get hold of the necessary clients and libraries.</p> <p>You can simply launch a VM in your OpenStack Personal Project, as follows:</p> <pre> # ssh lxplus7-cloud-testing # openstack server create --image 2ddd02c9-68df-4507-b329-9dec05635543 --flavor m2.medium --key-name &lt;YOURKEYPAIR&gt; &lt;YOURUSERID&gt;-handson</pre> <p>The last part of the training will involve some examples running on Kubernetes.</p> <p>Please try to create a cluster in advance, issuing the following command:</p> <pre> # ssh lxplus7-cloud-testing # openstack coe cluster create --cluster-template kubernetes --node-count 1 --keypair &lt;YOURKEYPAIR&gt; &lt;YOURUSERID&gt;-handson-kub</pre> <p>If you need any help prior to the session contact one of the organizers.</p>
