The document discusses new runtimes in OpenWhisk for supporting Go, Swift, and binary actions. Specifically: - A new ActionLoop runtime was created to efficiently support Go actions and be more performant than the Docker skeleton runtime. - The ActionLoop runtime was extended to support generic binaries, scripting languages like Bash and Haskell, and compiling Go and Swift actions from source code. - Images with the ActionLoop runtime can be used both to execute actions directly and to compile Go and Swift actions offline.
OpenWhisk Go/Swift/Binaries Runtime
- 2. What is it? • At the core, a new runtime – born to support GO Actions – designed to be efficient than the docker skeleton – action loop • It was extended to support – generic binaries (and scripts!) – compilation of go actions in source code – improved swift actions – images-as-compilers for offline compilation
- 3. A quick reminder why the "action loop" Test: 100 threads executing 100 actions executed on OSX using Docker for Mac (executables compiled for linux-amd64) Go performances against DockerSkeleton
- 4. The ActionLoop "Protocol" X fd3 stdout +
- 5. ActionLoop: a simple concept • Works for any binary executable – very similar to an unix pipe – it is actually implemented with pipes • Provides high performances – because the binary is started once – and it is kept running • The simple idea: – A binary must: – Loop on • read one line of text in stdin • decode it as a json • execute the action • log in stdout and stderr • output in fd3 – Why fd3? long story short: compatibility
- 7. ActionLoop Images actionloop actionloop- golang-1.9 actionloop- swift-v4.1 Supports Generic Binaries AND Generic Scripts (BASH, Haskell...) Supports Generic Binaries AND GoLang Sources Supports Generic Binaries AND Swift Sources replace or complementing dockerskeleton?
- 8. GoLang/ Swift samples The images can compile those actions
- 9. New Feature: offline compilation • Images actionloop-golang-v1.9 and actionloop-swift-v4.1 compiles on the fly • They can be also used as offline compilers: – place your source in src – docker run -v $PWD/src:/src –v $PWD/out:/out actionloop-golang-v1.9 compile – the binary is left in out/main
