+# lambder-replicate-snapshots
+
+replicate-snapshots is an AWS Lambda function for use with Lambder.
+
+REQUIRES:
+* python-lambder
+
+## Getting Started
+
+1) Test the sample lambda function
+
+    python lambda/replicate-snapshots/replicate-snapshots.py
+
+2) Deploy the sample Lambda function to AWS
+
+    lambder functions deploy
+
+3) Invoke the sample Lambda function in AWS
+
+    lambder functions invoke --input input/ping.json
+
+4) Add useful code to lambda/replicate-snapshots/replicate-snapshots.py
+
+5) Add any permissions you need to access other AWS resources to iam/policy.json
+
+6) Update your lambda and permissions policy in one go
+
+    lambder functions deploy
+
+## Sharing your lambder function
+
+If you decide to share your lambder function, you want to be sure you don't share
+the name of your s3 bucket. We suggest you add `lambder.json` to your
+`.gitignore` so it won't be commited to your repo. Instead, copy it to
+`example_lambder.json` and remove any secrets before pushing to a public
+repository.
+
+## Using virtualenvwrapper
+
+Your Lambdas should be as small as possible to reduce spinup time. If you need
+to include extra python modules, use virtualenvwrapper.
+The deploy script will look for a site-packages directory in
+$WORKON_HOME/lambder-replicate-snapshots and bundle those packages into the zip
+that it uploads to AWS Lambda.
