Kab lus no xaus cov ntawv txhais lus ntawm OpenWhisk los ntawm tus sau . Niaj hnub no peb yuav saib cov txheej txheem ntawm kev xa tawm OpenWhisk hla Kubernetes nrog cov lus raug kho kom ua haujlwm nrog cov ntawv thov tam sim no. Nws tseem yuav npog cov txheej txheem ntawm kev khiav haujlwm OpenWhisk siv Knative thiab TektonCD ntawm Kubernetes siv Nodejs runtime.
Deploying OpenWhisk ntawm Kubernetes
Ob peb hnub dhau los, kuv tau sim siv OpenWhisk rau Kubernetes los tsim qhov chaw sim yooj yim thiab nrawm. Thiab txij li thaum kuv yog tus tshiab rau Kubernetes, kuv ntseeg tias ib hnub thiab ib nrab tau siv rau kev xa mus ua tiav. IN Cov chaw khaws cia muaj cov lus qhia meej heev rau kev xa tawm OpenWhisk ntawm Kubernetes. Nov yog cov lus qhia xa mus rau Mac (Kuv kuj yuav ua txhua yam ntawm Linux vim kuv nyiam Linux. - kwv yees. tus txhais lus).

Txhim kho OpenWhisk hla Knative
Priti Desai tau ua tiav qhov kev teeb tsa saum toj ntawm pawg hauv IBM huab, nrog rau ntawm lub minikube tsis tu ncua, siv Knative Build thiab BuildTemplates. Kuv tseem yuav nruab rau saum minukube, raws li yuav ua li cas nyob rau hauv peb blog ua ntej - siv qhov tseeb software versions. Txij li thaum Knative Build thiab BuildTemplates tau raug tso cai tawm, kuv yuav siv qhov kev pom zoo hloov hauv daim ntawv Tekton Pipelines. Cov seem ntawm tsab xov xwm tau sau tom qab nyeem cov ntaub ntawv rau Tekton Pipelines, tab sis yog raws li cov tswv yim ntawm Priti. Txhawm rau ua haujlwm, koj yuav tsum nkag mus rau qee qhov Docker Registry - Kuv, zoo li tus thawj sau, yuav siv DockerHub.
