Things that requires travis org admin access,

• [x] Enable travis for this repo (done by @acorncom)

Set the following,

travis env set AWS_ACCESS_KEY_ID "$AWS_ACCESS_KEY_ID"
travis env set AWS_SECRET_ACCESS_KEY "$AWS_SECRET_ACCESS_KEY"
travis env set COUCH_USERNAME "$COUCH_USERNAME"
travis env set COUCH_PASSWORD "$COUCH_PASSWORD"

• [ ] Replace the COUCH_URL in .travis.yml with actual db
• [ ] If the target couch db is a new one, we need to populate it with at least v1 docs since generating docs for both v1.x and v2.x takes more than 50mins which is the max period for travis builds.

Status update here: just gave @sivakumar-kailasam access to what I'm aiming to have be the official Couch account (https://emberjs.cloudant.com/). He's going to work on some things there and I'll work on tracking down AWS details

[sivakumar-kailasam]

Populating the docs from my local partially for 1.x docs to begin with.

[sivakumar-kailasam]

I've indexed v1 docs from my machine. I need help with,

• [x] Enabling cron on a daily/hourly basis so that new docs will get published w/o us having to do anything.
• [x] Setting the ember-learn team's encrypted AWS creds for travis

[sivakumar-kailasam]

@acorncom I've replaced my personal keys for AWS since core would anyway update all keys related to cloudant, heroku and AWS. So #12 is good to merge. Do enable the cron for an hourly run though via travis UI (can't be enabled via config)

[sivakumar-kailasam]

The generator code & travis works off my s3 bucket for the generated docs. Need to get the core team to give us a s3 bucket & setup keys for us

[acorncom]

S3 bucket and keys is on the agenda for a conversation with Godfrey Chan on Friday

Travis CI setup is over for this repo. Tracking new doc publishes via #30
