问题 I've been struggling so long with the error below. I've tried so many tutorials and stackoverflow answers and none of the solutions fixes my problem.

How to deploy SAM stack with localstack?

由 点点圈 提交于 2020-06-01 01:45:15
问题 I've written a SAM stack and I can build, package and deploy it on AWS. I can also use start-local or invoke to test. Now I need to test to other AWS resources. I've added those resources to my SAM template. It works well on AWS but I'm searching for a way to deploy my SAM stack in localstack (local dynamodb e.g.). Now I have to create the resources with the CLI and after that I can deploy my SAM stack (only lambda, API GW in this case). How can I do this? 回答1: I've just gone through this. I

Preflight response 403 forbidden. How can I allow options method without x-api-key?

由 偶尔善良 提交于 2020-04-30 08:47:22
问题 I'm using SAM to create my API in cloudformation. I'm getting a 403 FORBIDDEN on my options method (thus also my preflight for my get method). How can I allow my options method to reply with 200 OK without my x-api-key? I've tried so many stackoverflow answers but none fit my SAM template format. I've tried all the different combinations of my AllowHeaders. I've ommited the x-api-key - still the same 403 FORBIDDEN. If I send my x-api-key in postman with my request I get a 200 OK, but in my

Recommended Project Structure for multi-function SAM Template

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-22 08:47:47
问题 I have a new project that requires a relatively small amount of services, maybe 10 or less (and therefore it is not economical to place each in a separate project repository). Each service will be defined as an AWS::Serverless::Function via SAM Template. My question is: what is the recommended way to organize or structure such a project? Currently the structure is: |- src |- lambdas |- service-one |- stuff |- package.json |- service-two |- stuff |- package.json |- other-stuff |- test |-

Kotlin recommended way of unregistering a listener with a SAM

由 久未见 提交于 2019-12-11 00:28:16
问题 So i have an interactor which performs an insert operation with Realm and then notifies that the insertion is completed with a RealChangeListener. It is something like this: fun insertCar(item: Car) { realm.doInTransaction { val car = Car(...) val copy = copyToRealm(car) copy.addChangeListener(...) } } I can do it this way: fun insertCar(item: Car, listener: RealmChangeListener<Car>) { realm.doInTransaction { val car = Car(...) val copy = copyToRealm(car) copy.addChangeListener(listener) } }

But somehow i still have to manually configure the app client settings, domain, and federated identities to have a working login portal for the users. I have been looking here and there for possible solutions in automating these, but i cannot seem to find anything close to it. I would like to automate the configuration of the app client settings, domain, and federated identities via
