Small sample program to facilitate discussions

Description

./app.py invokes a get() or post() operation, depending on absense or presence of a payload argument consisting of a JSON payload containing a "message" string property.

The counter value is stored in a DynamoDB table that has a single row with id and counter_value attributes. The key field id can be overridden by export COUNTER_KEY=some-key.

• the get() function returns a JSON payload:

  • current time
  • current counter_value from the DynamoDB table
  • and the message Automation For The People

• the put() function takes a JSON payload containing a message property as input, and also returns a JSON payload:

  • current time
  • incremented counter_value from the DynamoDB table
  • and a copy of message that was passed on the command line.

Setup:

Type make all to:

• install python3 prerequisites stored in requirements.txt
• deploy a tiny Cloudformation stack creating the DynamoDB table.

Example Usage:

• The retrieve the current time and the current counter value (the get() function):

  ./app.py
  

• To echo an arbitary message, and increment the counter (the put() function):

  ./app.py '{ "message" : "some-string" }'
