Munyika yekuvandudza masisitimu uye manejimendi, imwe yeakanyanya hunyanzvi matekinoroji emakore achangopfuura ne Docker midziyo. Iyi puratifomu yakashandura mavakirwo ezvikumbiro, kutumirwa, uye kumhanya, zvichiita kuti nharaunda inoshanduka uye inoshanda. Muchikamu chino, tichatarisa zvakadzama kuti Docker chii, kuti inoshanda sei, uye kuti iwe unogona sei kuwana zvakanyanya kubva pairi kuti uvandudze mafambiro ako.
Kana iwe wakambonetsekana nekuenderana kwesoftware munzvimbo dzakasiyana siyana kana kusangana nematambudziko ekufambisa maapplication kubva mukusimudzira kuenda pakugadzira, Docker ndiyo mhinduro yawanga uchitsvaga. Yayo mudziyo-yakavakirwa nzira inobvumira maapplication kuve akawanda malaptop, inopindirana y nyore kubata.
Chii chinonzi Docker?
Docker inzvimbo yakavhurika sosi yakagadzirirwa kuvandudza, kutumira, uye kumhanyisa zvikumbiro zvemidziyo. Chinangwa chayo chikuru kudzikisa matambudziko ekuenderana pakati penzvimbo nekuputira zvese zvinodiwa pakumhanyisa application mupakeji imwe.
Mukutaura kwakapfava, mudziyo weDocker chinhu chinotakurika chinosanganisira chishandiso uye zvese zvaro Runtime environment, semaraibhurari, zvinoenderana, uye zvigadziriso. Izvi zvinoreva kuti iwe unogona kumhanyisa application yako pane chero system ine Docker yakaiswa pasina kunetsekana nezvayo kusawirirana kweshanduro kana zvigadziriso.
Docker midziyo inoshanda sei?
Kusiyana neiyo michina chaiyo Kusiyana nemidziyo yechinyakare inoda yakazara sisitimu yekushandisa kune yega yega application, Docker midziyo inogovera iyo host inoshanda sisitimu, ichiita kuti ive yakareruka uye inoshanda zvakanyanya. Chigaba chega chega chinomhanya chakazvimiririra, chichiva nechokwadi chekuti maapplication haapindirane.
Docker's performance process yakavakirwa pa:
- Docker Mifananidzo: Iwo matemplate asingashanduke ane zvese zvinodiwa kumhanyisa mudziyo.
- Midziyo: Ivo vari kuita zviitiko zveDocker mufananidzo.
- Docker Injini: Ndiro mushando unotarisira midziyo.
- Docker Hub: Nzvimbo yepamhepo inochengeta mifananidzo yakagadzirira kushandisa.
Mabhenefiti makuru eDocker midziyo
Kushandisa Docker kunopa akawanda mabhenefiti kana achienzaniswa nedzimwe nzira dzekuendesa. visualization uye software deployment:
- Kutakura: Docker midziyo inogona kumhanya pane chero sisitimu yekushandisa ine Docker yakaiswa.
- Kubudirira: Nekugovana system kernel, midziyo inoshandisa mashoma zviwanikwa pane chaiwo machina.
- Scalability: Inofambisa kugadzirwa uye manejimendi ezviitiko zvakawanda zvekushandisa.
- Kubatana: Inoita shuwa kuti iyo application inomhanya nenzira imwechete mukuvandudza uye kugadzira.
Docker vs. Virtual michina
Imwe yeanonyanya kuenzanisa iri pakati peDocker nemakina chaiwo. Kunyangwe ese ari maviri achibvumira maapplication kuti ashande munzvimbo dzakasarudzika, anoshanda zvakasiyana:
| Feature | Docker | Michina chaiyo |
|---|---|---|
| Kushandisa zviwanikwa | Low | Alto |
| Kutanga nguva | Kurumidza | Kunonoka |
| Kubatika | Alta | Pakati nepakati |
| Kuiswa kwemurwere kwake ega | Yakagoverwa nemugamuchiri | Complete insulated |
Kazhinji kutaura, Docker isarudzo iri nani kana kumhanya uye kushanda nesimba kuchidikanwa, nepo michina chaiyo inokodzera zvirinani kunharaunda uko kuzviparadzanisa nevamwe kuri pamberi.
Mafungiro akakosha mumidziyo yeDocker
Docker Injini
Ndiyo yepakati injini yeDocker uye inogonesa kumhanya kwemidziyo. Inoshanda pasi pemutengi-server modhi, uko iyo Docker Daemon inobata zvikumbiro uye inotarisira midziyo.
Docker hub
Iyo online repository kwaunogona kuwana zviuru zve mifananidzo yakagadzirira kushandisa kana kurodha yako. Kune mifananidzo yepamutemo yezvishandiso zvakakurumbira seNginx, MySQL uye Redis.
Docker Kudzora
Chishandiso chinorerutsa kumhanya midziyo yakawanda sechikamu cheimwe application. Yakanakira mapurojekiti anoda akati wandei akabatana masevhisi, sedatabase uye sevha yewebhu.
dockerfile
Iri faira remavara rine iyo mirairo kugadzira mufananidzo weDocker. Inokutendera kuti uite otomatiki kuvakwa kwemifananidzo yakasarudzika.
Kuendesa uye Kushandisa Docker Containers
Kuti utange kushandisa Docker, unofanira kutanga waiisa pane yako system. Kana yangoiswa, unogona kuona kuti zvese zviri kushanda nemazvo nekumhanya:
docker run hello-worldUyu murairo uchadhawunirodha uye womhanyisa mudziyo wekuyedza unosimbisa kuti Docker iri kushanda nemazvo.
Muenzaniso wekushandisa neDocker Compose
Kana iwe uine application inoda webhu server uye dhatabhesi, unogona kutsanangura zvese huduma mune faira docker-kunyora.yml uye womhanya navo ne:
docker-compose upIzvi zvinotanga ese masevhisi mumidziyo yakasiyana asi yakabatana.
Container Orchestration neKubernetes
Kana purojekiti ichikura uye ichida kubata akawanda midziyo pamaseva akasiyana, Kubernetes inova chishandiso chakakosha. Inobvumira:
- Automate deployments uye zvigadziriso.
- Tonga zviwanikwa uye kuenzanisa mutoro.
- Ita shuwa kuwanikwa kwepamusoro.
Kutenda kuDocker, manejimendi ekushandisa uye kutumira kwave kuita zvakanyanya uye kuchinjika. Kugona kwayo kugadzira nzvimbo dzakasarudzika uye dzinotakurika dzinoita kuti ive yakanakira vanogadzira uye zvikwata zveIT. Nezvishandiso zvakaita seDocker Compose uye Kubernetes, zvinokwanisika kuunza iyo kubudirira y scalability kune inotevera nhanho, zvichiita kuti zvive nyore uye zvakanyanya kudzora manejimendi ekushandisa mune chero nharaunda. Govera chishandiso ichi kuti vanhu vazhinji vazive nezvazvo..
