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 e au ngā mea katoa i runga i Linux, nā te mea e pai ake ana ahau Linux. — āhua. kaiwhakamaori).
- Te tāuta i te kaiwhakahaere mōkihi
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[I roto i te Linux Kāore tēnei taahiraa e hiahiatia ana, ahakoa kei te wātea te pia. — āhua. kaiwhakamaori]
- Tāpiri monomai
minikubeиkubelet:
$ asdf plugin-add kubectl
$ asdf plugin-add minikube[Anō, ka pekehia e mātou tēnei taahiraa Linux. — āhua. kaiwhakamaori]
- 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 0.25.2[kua tāutahia ngā putanga motuhake, engari i tirohia e au ngā mea katoa i runga i ngā putanga hou e wātea ana mō Linux; Ki taku whakaaro ka taea e koe te tāuta haumaru i te mea hou rawa atu. — āhua. kaiwhakamaori]
I roto i te Linux Ko te mahi o tēnei taahiraa he rite ki tēnei (kua tāutahia ngā mea katoa ki ~/bin, kei roto i taku PATH, tuhipoka a te kaiwhakamāori):
$ 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=RBAC[Ka pai nga mea katoa ki ahau me te roopu minikube 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
$ cd incubator-openwhisk-deploy-kube/

$ brew install kubernetes-helm
$ helm init # init Helm Tiller, не нужно на Helm v3+
$ kubectl get pods -n kube-system # verify that tiller-deploy is in the running state, не нужно на helm v3+
$ kubectl create clusterrolebinding tiller-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:default
$ helm install ./openwhisk/helm/ --namespace=openwhisk -f mycluster.yaml[I roto i te Linux Ka rerekē paku ngā putanga hou (i te wā nei ko te putanga 3.0.1). — āhua. kaiwhakamaori]

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.
