I was trying to update the existing CloudFormation stack with the below command.
aws cloudformation deploy
there is no option to pass parameter file with deploy option. we tried to pass parameter file with --parameter-overrides but it's giving the below error.
value passed to --parameter-overrides must be of format Key=Value
the command we try to execute is
aws cloudformation deploy --template-file sg.yml --stack-name Common-SG --parameter-overrides ip.json --no-execute-changeset
is there any way to pass the parameters in file with aws cloudformation deploy
Passing a parameters stored as JSON in a local file looks like:
aws cloudformation deploy \
--stack-name demo \
--template-file test.yml --parameter-overrides file://test.json \
and the test.json like this.
{
"Parameters": {
"BucketName": "myawesometestdemo"
}
}
test.yml

this might be too late already, but for the sake of future similar issue I found this answer on (https://github.com/aws/serverless-application-model/issues/111)
The command should look like:
aws cloudformation deploy --template-file sg.yml --stack-name Common-SG --parameter-overrides $(cat params.properties) --no-execute-changeset
Now this is not going to be a json file, since "parameter-overrieds" expects a Key=Value pairs!
workaround for this issue is pass parameters with jq command.
yum install jq
Below is the syntax for the same.
aws cloudformation deploy --template-file sg.yml --stack-name Common-SG --parameter-overrides $(jq -r '.[] | [.ParameterKey, .ParameterValue] | "\(.[0])=\(.[1])"' ip.json) --no-execute-changeset
