OpenWhisk
OpenWhisk is an open source, distributed Serverless computing platform able to execute application logic (Actions) in response to events (Triggers) from external sources (Feeds) or HTTP requests governed by conditional logic (Rules). It provides a programming environment supported by a REST API-based Command Line Interface (CLI) along with tooling to support packaging and catalog services. Additionally, it now provides options to host the platform components as Docker containers on various Container Frameworks such as Mesos, Kunernetes, and Compose.
Three most important issues to address in the move towards graduation:
- Est. release process for ZIP of source code
- Est. release process for Docker and other platform binaries
- Increase additional company and individual Contributors to maintain all project repos.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?
- It had been our intent to have Apache host our staging (and move it out of disparate private builds within various companies). However, INFRA indicates they only typically allocate 1 VM per project for use with demos and minor things. They indicate that perhaps a corporate donation is in order (ala. Spark).
- Goal: standup testing resources at Apache and utilize for public CI and performance testing of OpenWhisk on Kubernetes
- Needed resources:
- Minimum 5 worker node kubernetes cluster. Each worker nodes can be fairly modest (2-4 virtual cores; 4-8GB of memory)
- 2 nodes for control plane: Controller, Kafka,Nginx (each Docker containers)
- 1 node for CouchDB
- 2 nodes for Invokers (containers)
- See discussion here: OpenWhisk / Kubernetes proposed epics/action items/questions
- Minimum 5 worker node kubernetes cluster. Each worker nodes can be fairly modest (2-4 virtual cores; 4-8GB of memory)
- Formal hand-off of OpenWhisk trademark/logo from IBM needs to be executed; need to identify process for this.
- Discussion started w/ Apache legal via "legal-discuss" mailing list with subject "Trademark handoff for "OpenWhisk" name and logo".
How has the community developed since the last report?
- TBD
- The bi-weekly Zoom "Technical Interchange" continues to be well received and attended.
- Complete videos posted to OW YouTube channel and detailed notes to our CWIKI.
