I-Kubernetes 1.16 - indlela yokuthuthukisa ngaphandle kokuphula noma yini

Namuhla, ngoSepthemba 18, kukhishwe inguqulo elandelayo ye-Kubernetes - 1.16. Njengenjwayelo, ukuthuthukiswa okuningi nemikhiqizo emisha kusilindile. Kodwa ngingathanda ukudonsela ukunaka kwakho ezigabeni zefayela ezidingekayo CHANGELOG-1.16.md. Lezi zigaba zishicilela izinguquko ezingahle zephule uhlelo lwakho lokusebenza, amathuluzi okulungisa iqoqo, noma zidinge izinguquko kumafayela okulungiselela.

Ngokuvamile, badinga ukungenelela okwenziwa ngesandla...

Ake siqale ngokushesha ngoshintsho olungase luthinte wonke umuntu osebenze ne-kubernetes isikhathi eside ngokwanele. I-Kubernetes API ayisasekeli izinguqulo ze-API yensiza yefa.

Uma kukhona obengazi noma akhohlwe...Inguqulo ye-API yesisetshenziswa ikhonjiswe ku-manifest, kunkambu apiVersion: apps/v1

Okuthiwa:

Uhlobo lwensiza
inguqulo endala
Yini okufanele ishintshwe

Zonke izinsiza
izinhlelo zokusebenza/v1beta1
izinhlelo zokusebenza/v1beta2
izinhlelo zokusebenza/v1

ukuthunyelwa
idaemonset
ukuphindaphinda
isandiso/v1beta1
izinhlelo zokusebenza/v1

izinqubomgomo zenethiwekhi
izandiso/v1beta1
networking.k8s.io/v1

izinqubomgomo ze-podsecurity
izandiso/v1beta1
inqubomgomo/v1beta1

Ngingathanda futhi ukudonsela ukunaka kwakho eqinisweni lokuthi izinto zohlobo Ingress nayo ishintshile apiVersion on networking.k8s.io/v1beta1. Incazelo endala extensions/v1beta1 isasekelwa, kodwa kunesizathu esihle sokubuyekeza le nguqulo kuma-manifest ngesikhathi esifanayo.

Kukhona izinguquko eziningi kumalebula esistimu ahlukahlukene (amalebula we-Node) afakwe kuma-node.

U-Kubelet wayenqatshelwe ukusetha amalebula angafanele (ngaphambilini ayengasethwa ngokhiye bokuqalisa kubelet --node-labels), bashiya lolu hlu kuphela kuvunyelwe:

kubernetes.io/hostname
kubernetes.io/instance-type
kubernetes.io/os
kubernetes.io/arch

beta.kubernetes.io/instance-type
beta.kubernetes.io/os
beta.kubernetes.io/arch

failure-domain.beta.kubernetes.io/zone
failure-domain.beta.kubernetes.io/region

failure-domain.kubernetes.io/zone
failure-domain.kubernetes.io/region

[*.]kubelet.kubernetes.io/*
[*.]node.kubernetes.io/*

Amalebula beta.kubernetes.io/metadata-proxy-ready, beta.kubernetes.io/metadata-proxy-ready kanye ne-beta.kubernetes.io/kube-proxy-ds-ready azisangezwa kumanodi amasha, futhi izingxenye ezengeziwe ezengeziwe seziqalile ukusebenzisa amalebula ahluke kancane njengezikhethi zamanodi:

Isakhi
Ilebula endala
Ilebula yamanje

kube-ummeleli
beta.kubernetes.io/kube-proxy-ds-ready
node.kubernetes.io/kube-proxy-ds-ready

i-ip-mask-ejenti
beta.kubernetes.io/masq-agent-ds-ready
node.kubernetes.io/masq-agent-ds-ready

ummeleli wemethadatha
beta.kubernetes.io/metadata-proxy-ready
cloud.google.com/metadata-proxy-ready

I-kubeadm manje isusa ifayela lokuqala lokucushwa kwe-kublet ngemuva kwayo bootstrap-kubelet.conf. Uma amathuluzi akho abefinyelela leli fayela, shintshela ekusebenziseni kubelet.conf, egcina izilungiselelo zamanje zokufinyelela.

I-Cadvisor ayisanikezeli ngamamethrikhi pod_name и container_nameuma uzisebenzisile ku-Prometheus, hamba kumamethrikhi pod и container ngokulandelana.

Kukhishwe okhiye ngomyalo womugqa:

Isakhi
Ukhiye ohoxisiwe

hyperkube
--make-symlink

kube-ummeleli
--isitsha-somthombo

Isihleli siqale ukusebenzisa inguqulo ye-v1beta1 ye-API Yomcimbi. Uma usebenzisa amathuluzi enkampani yangaphandle ukuze uhlanganyele ne-API Yomcimbi, shintshela enguqulweni yakamuva.

Isikhashana sokuhlekisa. Ngesikhathi kulungiselelwa ukukhululwa 1.16, kwenziwa izinguquko ezilandelayo:

• isuse isichasiselo scheduler.alpha.kubernetes.io/critical-pod kunguqulo v1.16.0-alpha.1
• ibuyise isichasiselo scheduler.alpha.kubernetes.io/critical-pod kunguqulo v1.16.0-alpha.2
• isuse isichasiselo scheduler.alpha.kubernetes.io/critical-pod kunguqulo v1.16.0-beta.1

Sebenzisa inkambu spec.priorityClassName ukukhombisa ukubaluleka kwephodi.
