Clientset

A simple clientset interface to the k8s api-server.

Instructions

1. Install dependencies

    $ mkdir -p ${GOPATH}/src/k8s.io
    $ cd ${GOPATH}/src/k8s.io
    $ git clone https://github.com/kubernetes/code-generator.git
    $ git clone https://github.com/kubernetes/gengo.git
   

2. Generate the clientset

    Note: - the code-generator:
            - is not aware of Go modules
            - will read definitions from the pkg/apis/itemresource/v1 package in this (github.com/keith-cullen/clientset) module
            - place generated code in ${GOPATH}/src/github.com/keith-cullen/clientset
          - the generated code must be copied from $GOPATH/src/github.com/keith-cullen/clientset into this module
   
    $ cd clientset
    $ ${GOPATH}/src/k8s.io/code-generator/generate-groups.sh all "github.com/keith-cullen/clientset/pkg/client" "github.com/keith-cullen/clientset/pkg/apis" itemresource:v1
    $ cp -r ${GOPATH}/src/github.com/keith-cullen/clientset/pkg .
   

3. Create the CRD

    $ kubectl apply -f item_crd.yaml
    $ kubectl get ns
    $ kubectl get crds
   

4. Build and run

    edit run.sh
   
        KUBECONFIG=
        KUBERNETES_MASTER=
        KUBERNETES_SERVICE_HOST=
        KUBERNETES_SERVICE_PORT=
   
    $ go build
    $ ./run.sh
   

5. Show the CRD instance

    $ kubectl describe item item1 -n itemns
   

6. Clean the project

    $ ./clean.sh
