Hello world

[jeroenvandijk]

I've added a first implementation. A few notes:

• My first tests are succesful except for aws/doc, see below. See script/test for a working example
• I didn't have the right setup for the tools.deps uberjar creation used in script/compile so I used the setup from graalvm-clojure.
• This setup uses the graalvm configuration files generated via lein native-config. I only added three lines there
• Out of the box this pod supports the same credentials types as cognitects library. However customization is a bit harder due to the pods communication layer. For instance, I would need support for credential_process, something that is supported by other AWS tools, but this requires the implementation of a custom credential provider. This interface is not yet accessible outside of the pod. (some background here)

Hey @jeroenvandijk this looks really awesome and kudos to the effort!
One suggestion i have is to maybe use https://clojuredocs.org/clojure.core/with-out-str to proxy the call to (aws/doc ...) and capture the output of the call and send it back as a pod response? We need a shim method in the pod for this. What say?

[lispyclouds]

You could use an actual deftest like this to have better feedback

[jeroenvandijk]

Yeah you mean the use this for a proper unit test, right? I didn't think the unit test setup through yet. Should I look at one of the other pods for an example?

[lispyclouds]

yes and i think they are kinda simple and if you have better ideas for tests for the AWS ones that would be even more awesome!

[jeroenvandijk]

Ok cool, thanks! I'll have a better look tomorrow. Getting late here

@jeroenvandijk Here is an example bb script with tests included:

https://github.com/babashka/pod-babashka-sqlite3/blob/main/test/script.clj

This can be hooked up in CI

[jeroenvandijk]

Thanks! I've added tests now

[lispyclouds]

This can be surrounded by the with-out-str shim i think

[lispyclouds]

Then you can reply it as a map containing the out key like this That should handle it correctly

[jeroenvandijk]

I've captured the out value one level above 648a8c1 It's pretty close to the implementation of with-out-str

[jeroenvandijk]

Now with tests. I also added some missing namespaces. Everything seems to be working. Note that I haven't put it through serious AWS usage yet, but I believe it's a proper start.

Open items:

• with-out-str doesn't work for the output that comes from the pod. @borkdude Do we need to use something else then System/out or should I test it differently?
• migrate from leiningen to tools.deps like the initial setup by @borkdude (I need some assistence here)
• Setup CI script. @borkdude I assume you want to use CircleCI? I can otherwise look into a Github Action setup.

Oh and in addition I'm still thinking about how to integrate the credential interface for custom setups. But it's already usable without this addition through AWS environment vars.
