Ka mutu tenei tuhinga i te raupapa o nga korero kua whakamaoritia mo OpenWhisk mai i te kaituhi . I tenei ra ka titiro tatou ki te tukanga o te tuku OpenWhisk ki runga i nga Kubernetes me nga whakahau kua whakatikahia hei mahi me nga putanga o naianei o nga tono. Ka kapi hoki i te mahi whakahaere i nga mahi OpenWhisk ma te whakamahi i te Knative me TektonCD i runga i nga Kubernetes ma te whakamahi i te wa whakahaere Nodejs.
Te whakamahi i te OpenWhisk ki nga Kubernetes
I roto i nga ra torutoru, i whakamatau ahau ki te tuku OpenWhisk ki Kubernetes ki te hanga i tetahi waahi whakamatautau ngawari me te tere. A, i te mea he hou ahau ki a Kubernetes, e whakapono ana ahau kua pau te ra me te hawhe mo te tuku angitu. IN He tino marama nga tohutohu mo te tuku OpenWhisk ki runga i nga Kubernetes. Anei nga tohutohu tuku mo Mac (Ka mahia ano e ahau nga mea katoa i runga i te Linux na te mea he pai ki ahau te Linux. — āhua. kaiwhakamaori).

asdf, ka mutu ka whakatika aunoa~/.bash_profilehe rite ranei ki tenei:
$ brew install asdf
$ [ -s "/usr/local/opt/asdf/asdf.sh" ] && . /usr/local/opt/asdf/asdf.sh
$ source ~/.bash_profile- Tāpiri monomai

$ asdf plugin-add kubectl
$ asdf plugin-add minikube- Tāutahia te minikube me te kubelet:
$ asdf install kubectl 1.9.0
$ asdf global kubectl 1.9.0
$ asdf install minikube 0.25.2
$ asdf global minikube 0.25.2I runga i te Linux, ka mahia tenei mahi penei (kua whakauruhia nga mea katoa ki roto i te ~/bin, kua raarangi ki taku PATH, te tuhipoka a te kaiwhakamaori):
$ curl -L0 minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && mv minikube ~/bin/
$ curl -L0 https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && mv kubectl ~/bin/- Waihangahia he miihini mariko minikube (Me whakauru i mua i te Pouaka Virtual):
$ minikube start --cpus 2 --memory 4096 --kubernetes-version=v1.9.0 --extra-config=apiserver.Authorization.Mode=RBACminikube start , kaore he tawhā me nga uara taunoa. — āhua. kaiwhakamaori]

Done! kubectl is now configured to use "minikube"- Te huri i te whatunga i Docker ki te aratau moepuku:

$ kubectl create namespace openwhisk
$ kubectl label nodes --all openwhisk-role=invoker- Ka whiwhi tatou i nga ihirangi o te putunga me te whakakore i te momo mo te whakauru ki te konae mycluster.yaml:
$ git clone https://github.com/apache/incubator-openwhisk-deploy-kube.git

Te whakauru i te OpenWhisk ki runga Knative
I mahia e Priti Desai te whakaurunga ki runga ake o te kahui i roto i te kapua IBM, tae atu ki te minikube auau, ma te whakamahi i nga Knative Build and BuildTemplates. Ka whakauru ano ahau ki runga o te minukube, i runga i te pehea i roto i to maatau rangitaki i mua - ma te whakamahi i nga putanga rorohiko hou. I te mea kua whakakorehia a Knative Build and BuildTemplates, ka whakamahia e au te whakakapinga e taunakitia ana ki te ahua o Tekton Pipelines. Ko te toenga o te tuhinga i tuhia i muri i te panui i nga tuhinga mo Tekton Pipelines, engari kei runga i nga whakaaro o Priti. Ki te mahi, ka hiahia koe ki te uru ki etahi Docker Registry - Ko ahau, pera i te kaituhi taketake, ka whakamahi i a DockerHub.
