Wreck-It

•Misspell username•Upload Object to Container that doesn’t exist

•Create Server in a location that doesn’t exist

•Use a bad Flavor/Image•Remove Rackspace JARs from the classpath

•etc.

Bug Reports, Troubleshooting,

and Help

Bug Reports

•Get the version•Get the code•Get the wire and header logs•gist or pastie

Troubleshooting

•Download the version•Run the code•Compare the wire and header logs

Troubleshooting

•Isolate the problem•jclouds/User Problem (HTTP 4xx)•Rackspace Problem (HTTP 5xx)•Use curl to verify

Troubleshooting

•Debug the source code• mvn dependency:copy-dependencies "-DoutputDirectory=./lib" "-Dclassifier=sources”

Responding

•Ideally:• Contribute examples/doc• Send the link to the customer• jclouds.org/documentation/devguides/contributing-to-jclouds/

• github.rackspace.com/van5941/CLAs

Responding

•Encourage customers to join the jclouds community:• jclouds-user-subscribe@apache.org• www.mail-archive.com/user@jclouds.incubator.apache.org/

•developer.rackspace.com/support•javadocs.jclouds.cloudbees.net•#jclouds on IRC @ freenode.net•jclouds-user-subscribe@apache.org•jclouds-dev-subscribe@apache.org

Potpourri

•Moved to Apache Software Foundation•groupId change

• 1.6.0: <groupId>org.jclouds.X</groupId>• 1.6.1: <groupId>org.apache.jclouds.X</groupId>

•Package change• 1.6.0: import org.jclouds• 1.7 (2.0?): import org.apache.jclouds

Potpourri

•Google’s Guice & Guava•Removal of the AsyncApis in 1.7 (2.0?)•Dropping support for Java 1.6?•Cloud Files isn’t multi-region...yet•Cloud Databases in progress•More endpoints

Potpourri

•Command Line Interface•Jenkins Plugin•jclouds-chef•Who Uses jclouds?• CloudBees• Cloudify• EnterpriseDB• Pallet• ...

Potpourri

•More examples•Other installation methods•Stay up-to-date with jclouds• blog.phymata.com• @everett_toews

•What else can we do to stay in sync?
