OpenWhisk comes with a one megabyte limit for function ZIP files. This can be a too harsh limit for many practical purposes. In addition, the Node 6 action comes with a long list of pre-packaged depdendencies, including some of the most popular NPM packages. The newer Node 8 action does not include any pre-packaged dependencies, which means we are forced to trade-off between using a modern Node version or having access to useful packages.
Fortunately, OpenWhisk also supports the creation of custom Docker images, so we can circumvent this trade-off by creating a Docker image that has exactly the dependencies pre-installed that we need, without any of the stuff we don't need.
Make sure you have Docker installed and are logged in to Docker Hub. The image is published under the trieloff namespace.
$ ./build.shOnce the function has been deployed, it can be tested using npm test
The package is based on the dependency list of the original Node 6 image, with a number of modifications:
- updated dependencies to the newest version (thanks to Greenkeeper)
- removed deprecated and useless dependencies
- added dependencies that are specific to Project Helix
