Hello!
seems the readme's for a few of the examples are the same and also don't match the actual example.
readme is talking about a Slack slash command. Happy to update the readme once I've implemented the solution?
I've been trying to use kinesis-firehose-cloudwatch-logs-processor as part of my kinesis firehose stack, but because all Serverless applications get deployed as nested stacks there is no easy way to reference the resources in the parent stack if there are no outputs. For instance, "serverlessrepo-auto-subscribe-log-group-to-arn" application has outputs and can be easily integrated.
I strongly believe that before being published the applications need to have the resource outputs specified in the template.
Overall, I'm loving the Serverless Repo!
The source code URL in the SAR listing for kinesis-firehose-apachelog-to-json-python points at https://github.com/aws-samples/serverless-app-examples/tree/master/python/kinesis-process-record-python - it should instead point at https://github.com/aws-samples/serverless-app-examples/tree/master/python/kinesis-firehose-apachelog-to-json-python
The listing does however deploy the correct Lambda, it's just the source link that is incorrect.
While evaluating aws sam as a CD solution for lambda functions I had struggles finding appropriate guides or documentation, and had to combine random examples and guides to get my "safe deployment" pipeline working.
I managed to setup everything after consulting different github repos and guides, but the CodeDeploy Deployment fails with this message:
The IAM role arn:aws:iam::${awsacc}:role/${lambda-app-name}-CodeDeployServiceRole-${generated-version} does not give you permission to perform operations in the following AWS service: AWSLambda. Contact your AWS administrator if you need help. If you are an AWS administrator, you can grant permissions to your users or groups by creating IAM policies.
The implicitly generated IAM Role looks like this:
{
"Role": {
"Path": "/",
"RoleName": "${lambda-app-name}-CodeDeployServiceRole-${generated-version}",
"RoleId": "${SOME_ROLE_ID}",
"Arn": "arn:aws:iam::${awsacc}:role/${lambda-app-name}-CodeDeployServiceRole-${generated-version}",
