Seva Yopanda Makompyuta ndi OpenWhisk, Gawo 4

Nkhaniyi ikumaliza zolemba zomasulira za OpenWhisk kuchokera kwa wolemba Priti Desai. Lero tiwona njira yotumizira OpenWhisk pa Kubernetes ndi malamulo okonzedwa kuti agwire ntchito ndi mitundu yaposachedwa. Idzaphatikizanso njira yoyendetsera ntchito za OpenWhisk pogwiritsa ntchito Knative ndi TektonCD pa Kubernetes pogwiritsa ntchito Nodejs runtime.

Kutumiza OpenWhisk pa Kubernetes

M'kupita kwa masiku angapo, ndinayesa kutumiza OpenWhisk ku Kubernetes kuti apange malo oyesera osavuta komanso ofulumira. Ndipo popeza ndine watsopano ku Kubernetes, ndikukhulupirira kuti tsiku limodzi ndi theka linagwiritsidwa ntchito potumiza bwino. MU izi Zosungirako zili ndi malangizo omveka bwino operekera OpenWhisk pa Kubernetes. Nawa malangizo otumizira opangira Mac (Ndichitanso chilichonse pa Linux chifukwa ndimakonda Linux. - pafupifupi. womasulira).

  1. Kukhazikitsa woyang'anira phukusi asdf, pambuyo pake timakonza zokha ~/.bash_profile kapena kufanana kwake ndi izi:

$ brew install asdf
$ [ -s "/usr/local/opt/asdf/asdf.sh" ] && . /usr/local/opt/asdf/asdf.sh
$ source ~/.bash_profile

[Pa Linux sitepe iyi sikufunika, ngakhale brew ilipo. - pafupifupi. womasulira]

  1. Kuwonjezera mapulagini minikube ΠΈ kubelet:

$ asdf plugin-add kubectl
$ asdf plugin-add minikube

[Apanso, dumphani izi pa Linux. - pafupifupi. womasulira]

  1. Ikani minikube ndi 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

[matembenuzidwe enieni aikidwa, koma ndinayang'ana chirichonse pamitundu yaposachedwa ya Linux; Ndikukayikira kuti mutha kukhazikitsa zatsopano. - pafupifupi. womasulira]

Pa Linux, sitepe iyi yachitika motere (zonse zimayikidwa ~/bin, zomwe zalembedwa mu PATH yanga, zolemba za womasulira):

$ 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/

  1. Pangani makina a minikube (VirtualBox iyenera kukhazikitsidwa kale):

$ minikube start --cpus 2 --memory 4096 --kubernetes-version=v1.9.0 --extra-config=apiserver.Authorization.Mode=RBAC

[Zonse zimandiyendera ndi timu minikube start , opanda magawo komanso zosintha zosasintha. - pafupifupi. womasulira] 

$ minikube start
  minikube v1.5.2 on Debian 8.11
  Automatically selected the 'virtualbox' driver
  Downloading VM boot image ...

  Done! kubectl is now configured to use "minikube"

  1. Kusintha netiweki mu Docker kuti ikhale yachiwerewere:

$ minikube ssh -- sudo ip link set docker0 promisc on

  1. Pangani dzina ndikuyika chizindikiro cha ogwira ntchito:

$ kubectl create namespace openwhisk
$ kubectl label nodes --all openwhisk-role=invoker

  1. Timapeza zomwe zili munkhokwe ndikuchotsa mtundu wa ingress mu fayilo ya mycluster.yaml:

$ git clone https://github.com/apache/incubator-openwhisk-deploy-kube.git
$ cd incubator-openwhisk-deploy-kube/
$ cat << "EOF" > mycluster.yaml
whisk:
    ingress:
        type: NodePort
            api_host_name: 192.168.99.100
            api_host_port: 31001
nginx:
    httpsNodePort: 31001
EOF

  1. Ikani Helm ndikuyigwiritsa ntchito:

$ brew install kubernetes-helm
$ helm init # init Helm Tiller, Π½Π΅ Π½ΡƒΠΆΠ½ΠΎ Π½Π° Helm v3+
$ kubectl get pods -n kube-system # verify that tiller-deploy is in the running state, Π½Π΅ Π½ΡƒΠΆΠ½ΠΎ Π½Π° helm v3+
$ kubectl create clusterrolebinding tiller-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:default
$ helm install ./openwhisk/helm/ --namespace=openwhisk -f mycluster.yaml

[Pa Linux yokhala ndi matembenuzidwe aposachedwa (v3.0.1 inalipo) idzakhala yosiyana pang'ono. - pafupifupi. womasulira] 

$ curl -L0 https://get.helm.sh/helm-v3.0.1-linux-amd64.tar.gz | tar -xzvf - linux-amd64/helm --strip-components=1; sudo mv helm /usr/local/bin
$ kubectl create clusterrolebinding tiller-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:default
$ helm install ./openwhisk/helm/ --namespace=openwhisk --generate-name -f mycluster.yaml

Chidebe chokhala ndi dzina -ikani-package- kuwonongeka kwa Error

Ingowonjezerani nthawi yoyezetsa moyo wanu.

Kuyika OpenWhisk pa Knative

Priti Desai adakhazikitsa pamwamba pa gulu mumtambo wa IBM, komanso pa minikube wokhazikika, pogwiritsa ntchito Knative Build and BuildTemplates. Ndikhazikitsanso pamwamba pa minukube, kutengera momwe zinafotokozedwa mu blog yathu m'mbuyomu - pogwiritsa ntchito mapulogalamu aposachedwa. Popeza Knative Build and BuildTemplates idatsitsidwa mwalamulo, ndigwiritsa ntchito m'malo mwa Tekton Pipelines. Nkhani yonseyi idalembedwa nditawerenga zolemba za Tekton Pipelines, koma zidatengera malingaliro a Priti.
