Scripts

verify-weave.sh - Goes through all weave pods in the cluster, computes a checksum on the 'status ipam' list and tells you if there are any weave pods that disagree on their peer list. It was used this to identify the different groups of pods in the cluster and decide which we wanted to preserve and which ones we wanted to reset/restart. Another quick script bump-weave.sh - Used to remove the db file and restart for those weave pods we wished to reset.

Replace the Auth options hash value having token: <TOKEN_FOR_TESTING_THAT_LASTS_FOR_A_DAY> with an actual token. This token can be generated by the server side scripts and copied in. It supercedes the tokenUrl: if set.

Just to be 100% sure, feel free to verify the validity of the JSON Web Token generated using jwt.io, JWT debugger. Oh, and the TTL is set to 86400 which is a day. Enough time to generate a token and play around with it.

Ps: If there are any amendments that I can make to improve clarity or fix issues, feel free to leave a comment below. I'll get a notification and act on it as soon as I can.

Ps 2: I was experiencing an issue with CORS and so I submitted the issue (and this code) to the annotator-dev mailing list. Check the July 2014 archives for an email with the subject ... '[annotator-dev] Integrating Site With AnnotateIt Store'.
