CosmWasm builder

Building

Start by building the image:

docker build -t build-cosmwasm .

This will do an initial build to cache the cargo packages.

Running

With the container built, you can run the follow command to compile and run unit tests:

docker run -v $(pwd)/my-first-contract:/usr/src/myapp:rw build-cosmwasm

This is where you can use the volume mount to point the container to a different contract, or updated logic.

Example output

$ time docker run -v $(pwd)/my-first-contract:/usr/src/myapp:rw build-cosmwasm

As you can see, the total runtime was 3.961 seconds. I found this to be standard as long as there aren't large changes in the included dependencies.
