build.sh

The build.sh file has seven commands to make working with this app easier than it already is

• deps: go get and update all the dependencies
• clean: removes the ./bin folder
• test: uses SAM local and the event in event.json to test the implementation
• build: creates the executable
• getparams: updates the SAM template with the values from the AWS Systems Manager Parameter Store
• delparams: removes the values of the environment variables in the SAM template
• deploy: deploy the function to AWS Lambda

Prerequisites

While executing the the build script there are a few programs that are used:

• jq
• yq
• aws cli
• sam cli

AWS Systems Manager

Within the AWS Systems Manager Parameter store there are three parameters that are used in this app:

• /arn/trello
• /gocal*/clientsecret
• /gocal*/token
• /gocal*/interval
• /gocal*/tokenpointer
• /gocal*/cspointer

TODO

• Update the deps target in build.sh to make use of dep or simply have a smarter approach than list all dependencies
• Make sure that all the calls to SSM are correctly traced with XRay
• Come up with a better way to deploy the same function with different parameters
