Tsab xov xwm no xaus cov lus txhais ntawm OpenWhisk los ntawm tus sau. Niaj hnub no, peb yuav tham txog cov txheej txheem ntawm kev xa tawm OpenWhisk ntawm Kubernetes, nrog rau cov lus txib kho kom ua haujlwm nrog cov ntawv thov tam sim no. Peb kuj tseem yuav tham txog kev khiav OpenWhisk functions siv Knative thiab TektonCD hauv Kubernetes nrog Node.js runtime.
Kev Siv OpenWhisk Rau Kubernetes
Tau ob peb hnub, kuv tau sim siv OpenWhisk rau Kubernetes los tsim ib qho chaw sim yooj yim thiab ceev rau cov haujlwm. Thiab vim kuv tshiab rau Kubernetes, kuv kwv yees tias nws siv sijhawm ib hnub thiab ib nrab los ua kom tiav. Cov chaw khaws cia muaj cov lus qhia meej heev rau kev xa tawm OpenWhisk hauv Kubernetes. Nov yog cov lus qhia xa tawm rau Mac (Kuv tseem yuav ua txhua yam rau Linux, vim kuv nyiam Linux. — daim ntawv sau los ntawm tus neeg txhais lus).
- Txhim kho tus thawj tswj pob khoom
asdf, tom qab ntawd peb kho nws cia li~/.bash_profilelos yog nws sib npaug:
$ brew install asdf
$ [ -s "/usr/local/opt/asdf/asdf.sh" ] && . /usr/local/opt/asdf/asdf.sh
$ source ~/.bash_profile[rau Linux Cov kauj ruam no tsis tsim nyog, txawm hais tias brew muaj. - kwv yees. tus txhais lus]
- Ntxiv cov plugins
minikubeиkubelet:
$ asdf plugin-add kubectl
$ asdf plugin-add minikube[Dua li no, peb hla qhov kauj ruam no Linux. - kwv yees. tus txhais lus]
- Nruab minikube thiab 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[cov version tshwj xeeb tau teeb tsa, tab sis kuv tau kuaj xyuas txhua yam ntawm cov versions tshiab tshaj plaws rau Linux; Kuv xav tias koj tuaj yeem nruab qhov tseeb tshaj plaws tau yam tsis muaj teeb meem. - kwv yees. tus txhais lus]
rau Linux Cov kauj ruam no tau ua tiav ib yam dab tsi zoo li no (txhua yam tau teeb tsa hauv ~ / bin, uas yog nyob rau hauv kuv txoj kev, tus neeg txhais lus cov lus):
$ curl -L0 minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && mv minikube ~/bin/

Txhim kho OpenWhisk ntawm Knative
Priti Desai tau teeb tsa rau saum IBM huab cluster, thiab rau ntawm minikube ib txwm muaj, siv Knative Build thiab BuildTemplates. Kuv kuj tseem yuav teeb tsa rau saum minukube, raws li yuav ua li cas Kuv tau sau txog qhov no ua ntej hauv peb lub blog siv cov software versions tshiab. Txij li thaum Knative Build thiab BuildTemplates tau raug tshem tawm lawm, kuv yuav siv qhov hloov pauv uas pom zoo, Tekton Pipelines. Cov ntawv sau tas los tau sau tom qab nyeem cov ntaub ntawv Tekton Pipelines, tab sis yog raws li Priti lub tswv yim. Tsab ntawv no yuav xav tau kev nkag mus rau Docker registry - zoo li tus sau thawj, kuv yuav siv DockerHub.
