Passing a JSON file as environment variable to aws lambda update-function-configuration cli

Question

I am looking for a solution to pass a JSON file as environment variable to aws lambda update-function-configuration cli.

for example:

aws lambda update-function-configuration --function-name "test" --environment var.json

and the variable JSON file would be:

{
  "Variables": {"string": "string",
    ...}
}

So, basically looking for a dynamic solution to insert environment variables to Lambda function via CLI.

Thanks in advance

Answer 1

Assuming the content of the var.json is as follow:

{
    "key1":"value1",
    "key2":"value2"
}

Then you can run the aws cli like this:

aws lambda update-function-configuration --function-name "test" --environment "{\"Variables\":`cat var.json`}"
