openwhisk-kubernetes-installer

This is a simple way to install and run Apache OpenWhisk locally. It requires Docker for Mac with Kubernetes enabled, and uses the OpenWhisk Deployment on Kubernetes. Most of the installer logic is in the alexkli/openwhisk-kubernetes-installer docker image used by the install script.

Requirements

  • Docker for Mac
  • with Kubernetes enabled
  • with 4 GB of RAM (advanced Docker settings)
  • with docker-for-desktop context (should be the default)
  • with a docker network host that allows access to the host from the containers via localhost (should be available by default)

Install

Single command:

docker run --net=host -v ~/.kube:/root/.kube alexkli/openwhisk-kubernetes-installer

Alternatively use this script from this git repository (which might do some more checks in the future):

./install-openwhisk.sh

This might take a few minutes.

The output should end with instructions how to install wsk and with the ~/.wskprops to use:

APIHOST=http://localhost:31001
AUTH=23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP
NAMESPACE=guest

Openwhisk experts: Please note that the API host is HTTP and not HTTPS, which avoids the annoying self-signed certificate issue that would have required use of wsk -i everywhere. Not using SSL is fine since this is only meant for local development installations.

Verify that it works:

wsk namespace get

Should output:

Entities in namespace: guest
packages
actions
triggers
rules

Stop/remove

Quitting Docker for Mac or stopping it's Kubernetes will shut things down. When starting it again, openwhisk should come back up.

To remove the installation, run this while Docker for Mac & Kubernetes is running:

./uninstall-openwhisk.sh

Admin commands

wskadmin

To run wskadmin, use the included wskadmin script:

  • create a user/namespace

    ./wskadmin user create userA
    
  • list all users/namespaces

    ./wskadmin db get subjects | grep key
    

helm

helm is also available as script. This can be used to inspect or manage the running environment, for example:

./helm get openwhisk

Develop

The alexkli/openwhisk-kubernetes-installer docker image is in the docker/ folder. Build it using make.

You can’t perform that action at this time.
