CodePipeline CloudFormation Template configuration

Question

I'm trying to use the CloudFormation Template configuration field in a CodePipeline. If you edit the CloudFormation in CodePipeline it looks like this:

If my InputArtifactName is MyAppBuild and I have a CloudFormation config file in cfg-prd.json, my hope was I could enter MyAppBuild::cfg-prd.json and have it pick it up.

I get an error about the template file not being valid even though it works manually as:

--parameters cfg-prd.json

Answer 1

A nice trick to see what the Cloudformation layout should be is to create a pipeline which you know will work. Then use the CLI to extract a cloudformation template.

aws codepipeline get-pipeline --name <pipelinename>

You will get the JSON of the Codepipeline resource. There will be a few changes required but from this you can see exactly what the syntax should be and from there parameterised your template and create Codepipelines programatically.
