Sei Kubespray?
Takasangana naKubernetes makore anopfuura maviri apfuura - izvi zvisati zvaitika takanga tine ruzivo rwekushanda neApache Mesos uye takabudirira kusiya docker swarm. Naizvozvo, kuvandudzwa kwek8s kwakabva kwatevera iyo Brazilian system. Hapana minicubes kana manejimendi mhinduro kubva kuGoogle.
Kubeadm panguva iyoyo aisaziva kuunganidza etcd cluster, uye yedzimwe sarudzo, kubespray yaive mumusoro mibairo yeGoogle.
Takaitarisa tikaona kuti taifanira kuitora.
Musi waSeptember 23, 20.00 nguva yeMoscow, Sergey Bondarev achaitisa , kwaanozokuudza nzira yekugadzirira kubespray kuitira kuti ive inonaka, inoshanda uye isingatenderi kukanganisa, uye ipapo pfungwa "haasi ese mayoga ane hutano hwakaenzana" haimuke.
Pawebinar, Sergey Bondarev achakuudza mashandiro anoita kubespray, chii musiyano kubva kubeadm, kops, rke. Iye achagovera akasarudzika maficha ekubespray uye iyo cluster yekumisikidza algorithm. Ichaongorora maficha (zvakaipira) zvekushanda kwemaindasitiri.
Saka sei tichibata kubespray nemaoko ese ari matatu?
- Inonzwisisika uye yakavhurika. Iwe unogona kugara uchiwedzera dzimwe nguva iwe pachako.
- Unogona kuimisa paCentos, uye pane kumwe kugoverwa π
- HA-setup. Kutadza-kushivirira etcd cluster ye3 masters.
- Kugona kuwedzera node uye kugadzirisa cluster.
- Kuiswa kweimwe software senge dashboard, metrics server, ingress controller, nezvimwe.
Iyo ansible script inoshandawo ne mitogen. Izvo zvinopa kukwidziridzwa kwe10-15%, hapasisina, nekuti yakawanda yenguva inopedzwa kurodha mifananidzo nekuiswa.
Nechinangwa kutaura, panguva ino sarudzo yekubespray yekumisikidza cluster haina kunge iri pachena sezvazvaive makore maviri apfuura.
Muchidimbu...
Semuenzaniso, kops - inoita senge cubespray inokutendera iwe kuti uise sumbu kubva pakutanga, kunyange kugadzira chaiwo michina iwe pachako. Asi chete AWS, GCE uye openstack basa. Ndeupi rudzi runomutsa mubvunzo - nei ichidikanwa kana makore aya aine manejimendi ekugadzirisa, kunyangwe mune yakavhurika stack, semuenzaniso selectel kana mail.ru. rke - vamwe vanhu vanoifarira, asi ivo vane yavo nzira yekuumbwa kwesumbu ririkugadzirwa uye havana mikana mikuru yekugadziridza zvikamu zvemasumbu. Uyezve, iwe unoda yakatomisikidzwa node ine docker yakaiswa. kubeadm - inodawo Docker, chishandiso kubva kuvagadziri veKubernetes, iyo yakazodzidza nzira yekugadzira-inoshivirira setups, chengetedza iyo config uye chitupa mukati mesumbu, uye ikozvino hapana chikonzero chekufambisa mafaera aya pakati pemanodhi. Chishandiso chakanaka, asi chakanangana chete nekusimudza bani rekutonga. Iyo haina kana kuisa network musumbu, uye zvinyorwa zvinoratidzira kushandisa zviratidziro neCNI pamurume.
Zvakanaka, chokwadi chakakosha ndechekuti zvese izvi zvitatu zvinoshandiswa zvakanyorwa mukuenda, uye kana iwe uchida chimwe chinhu chakasiyana, iwe unofanirwa kuziva enda kuitira kugadzirisa kodhi uye kugadzira chikumbiro chekudhonza.
Cubspray chinhu chinobatika chiri nyore kudzidza pane kuenda.
Zvakanaka, uye zvakadaro, uchishandisa zvakafanana zvinonzwisisika, unogona kunyora ako ega zvinyorwa zvekuisa docker uye sumbu uchishandisa rke kana kubeadm. Uye aya manyoro, nekuda kwehunyanzvi hwawo hudiki kune zvaunoda, achashanda nekukurumidza kupfuura cubespray. Uye iyi yakanaka, inoshanda sarudzo. Kana uine kugona uye nguva.
Uye kana iwe uchangotanga kujairana , ipapo kubata cubespray kuchava nyore uye nekukurumidza.
Uye icho chingori chikamu chezvatichataura nezvazvo. Hazvizove zvinofinha. Huya uye . Kana kunyoresa uye . Chero zvaungada.
