He waeine pūmanawa iti, kawe hoki te ipu Docker e tākai ana i ngā mea katoa e hiahiatia ana hei whakahaere i tētahi tono: te waehere, te wā whakahaere, ngā whare pukapuka, me ngā taputapu pūnaha. Mō ngā tīma DevSecOps, ngā kaiwhakawhanake, me ngā tohunga haumarutanga, he mea nui te mārama he aha te ipu Docker kia taea ai te hanga i tētahi tuku tauine me te haumaru. pipelines.
Kāore i rite ki ngā mīhini mariko, kāore ngā ipu e mau ana i tētahi pūnaha whakahaere katoa. Engari, ka tohaina e rātou te kernel OS manaaki i a rātou e whakahaere ana hei tukanga motuhake. Mā tēnei hoahoa ka whakaitihia te utu nui, ā, ka taea e ngā ipu te tīmata tata tonu, ā, ka pai ai mō te whakawhanake me te whakatinanatanga pūmanawa hou. Ina ngana ana ki te mārama he aha te ipu i roto i te Docker, he mea tino nui kia mōhio ki ngā painga whai hua e whakaratohia ana e ia. Me whakaaro te hunga e whakaaro ana he aha te ipu Docker hei huarahi mahi-teitei ki te mariko tuku iho.
Tautuhinga:
Nā, he aha te ipu Docker i te ao tūturu? #
Koinei te taputapu e whakawhirinakihia ana e ngā kaiwhakawhanake mō te whanonga taupānga ōrite puta noa i ngā taiao. Ahakoa kei te whakatinana koe ki te whakaaturanga, ki te whakaputa rānei, mā te mārama ki te aha te ipu Docker ka āwhina i te whakarite kia maeneene te whakawhiti. Arā, he tauira ora te ipu i roto i te Docker o te ahua Docker. Whakaarohia te ahua hei mahere, hei tauira rānei e whakauru ana i te tono me ōna whakawhirinakitanga katoa. Ina whakarewahia, ka noho hei ipu: he tukanga e rere ana, e whai mana ana me tana ake pūnaha kōnae, whatunga, me ngā rohe rauemi. Ka wehea ia ipu mai i ētahi atu me te pūnaha manaaki, ahakoa ka taea te whakawhitiwhiti kōrero mā roto i ngā āhuatanga whatunga a Docker. I roto i ngā tatūnga uaua ake, ka whakaritea ngā ipu mā te whakamahi i ngā taputapu pēnei i a Kubernetes, ka taea ai e rātou te mahi tahi hei wāhanga o tētahi pūnaha nui ake. Hei mārama ake ki te aha te ipu i roto i te Docker, whakaarohia tōna ngāwari ki te whakarahi i ngā ratonga moroiti.
Ngā Āhuatanga Matua o ngā Ipu Docker #
Kōmāmā: Ka tiritiri i te kernel OS manaaki, nō reira kāore e hiahiatia he tāutanga OS katoa
kawe: Ka oma rite tonu puta noa i ngā taiao rerekē
Kua wehe: Ka wehea ngā tukanga, ngā pūnaha kōnae, me ngā whatunga
Ka taea te whakaputaI hangaia mai i ngā kōnae Docker mō ngā taiao ōrite
Whakaoho TereKa whakarewahia i roto i ngā mirihekona, ka tere ake te whanaketanga me te whakatinanatanga
Hanganga Ipu Docker #
Ina kōrero te tangata mō te "ipu Docker," ko te tikanga whānui o te tūāpapa Docker te tikanga. Mā te mārama ki te aha te ipu Docker ka mōhio ki ōna wāhanga:
- Mīhini Docker: Te wā whakahaere matua mō te hanga me te whakahaere i ngā ipu
- Ngā Whakaahua o Docker: Ngā mahere pumau mō ngā ipu
- Kōnae Docker: He tuhinga e whakamārama ana me pēhea te hanga i tētahi ahua
- Rēhita Docker: Rokiroki me te tiritiri i ngā whakaahua (hei tauira, Docker Hub)
- Docker CLI me te API: Ngā atanga mō te whakahaere i ngā ipu
Mā ēnei taputapu katoa ka taea te tuku tere, te tukurua hoki o ngā pūmanawa me te iti o te raruraru whakatū. Mā te tūhura i te mea he ipu Docker ka kitea tōna hiranga ki ngā hanganga hou.
Ngā Whakamahinga Noa mō ngā Ipu Docker #
Ngā ratonga iti: Whakahaerehia ngā ratonga motuhake e tauine motuhake ana
CI/CD Pipelines: Me whakarite kia rere ngā hanganga me ngā whakamātautau i roto i ngā taiao ōrite
Ngā Taiao Whakawhanake/Whakamātautau: Tohaina ngā whakaritenga matapae puta noa i ngā tīma
Ngā Taupānga Kapua-Tangata Whenua: Whakakotahitia ki ngā papaaho whakarite
Te Whakatakotoranga Haumarutanga: Whakamātauria te waehere takitahi hei ārai i te mōrearea
E whakaatu ana ēnei tauira whakamahinga i te maha o ngā whakamahinga o ngā ipu Docker i roto i ngā horopaki o te ao tūroa.
Nga Whakaaro Haumaru #
He rite tonu te hiranga o te haumarutanga ki te mahi. Ko ngā mahi pai rawa atu ko:
- Whakamahia ngā Whakaahua Taketake Iti rawa: He iti ake te mata whakaeke
- She kēne mō ngā ngoikoretangaHopukia ngā take i te tīmatanga o te pipeline
- Mana iti rawa: Kaua e rere hei pakiaka
- Ngā Pūnaha Kōnae Pānui-Anake: Maukatihia ngā ipu
- Waitohu Whakaahua: Whakamahia te Docker Content Trust hei manatoko i te pono
Kei te hipoki te haumarutanga i te katoa pipelinemai i te waihanga whakaahua ki te whakarite ipu me te whakapakeke i te OS manaaki. Ngā taputapu pēnei i Xygeni tautokona tēnei mā te matawai i ngā ngoikoretanga, ngā mea ngaro, me ngā whirihoranga hē puta noa i te CI/CD rerengamahi. Ko tētahi wāhanga o te mārama ki te aha te ipu Docker ko te mōhio ki ōna kawenga haumarutanga.
Whatunga me te Rokiroki #
E tautoko ana a Docker i ētahi kōwhiringa whatunga:
- Piriti: Ngā whatunga ipu taunoa, motuhake
- Kaihautū: Ka tiritiri i te puranga whatunga a te kaihautū
- Whakakikoruatia: Whakamahia i roto i ngā taiao maha-kaihautū
- Macvlan: Ka tohaina ngā wāhitau MAC mō te whakaurunga ki ngā whatunga ā-tinana
Mō te rokiroki, ka tukuna e Docker:
- Rōrahi: E whakahaerehia ana e Docker, ā, e pai ake ana mō te pumau
- Ngā Maunga Here: Te urunga tika ki ngā whaiaronga manaaki
He whai hua te Whakahaere Rauemi me ngā Ipu Mahi, engari he mea nui ngā rohe rauemi. Mā Docker ka taea e koe te whakawhāiti i te CPU, te mahara, te I/O, me ētahi atu mā te whakamahi i ngā taputapu pēnei i ngā rōpū-c me ngā mokowā ingoa. Mā tēnei ka noho tonu ngā ipu ki tō rātou ara me te kore e hemokai i ētahi atu tukanga. Ko ēnei āhuatanga he wāhanga o te turanga mō te whakatikatika mahi.
I te mea he nui ake ngā tīma e whakamahi ana i te whakapūmau ipu, mā te mārama pai ki te tikanga o te Docker ipu ka pai ake te whakahaere.ciste hanga katote e pā ana ki te tohatoha rauemi me te tauine mahi.
He aha te hiranga o ngā Ipu Docker i roto i te DevSecOps #
Ehara i te mea ko te mōhio ki te hangarau anake te mea nui ki te mārama ki a Docker, engari ko te whakahohe i te whanaketanga tere, haumaru, me te tauine. Ka āwhina ngā ipu i ngā tīma kia tere te neke me te kore e whakaiti i te pono. Mō ngā tīma haumarutanga, ka tukuna e rātou he taiao e taea te matapae, e taea te whakahaere, e ngāwari ake ai te aroturuki me te whakapakeke. Whakapai ake i ngā rerengamahi o tō tīma me te haumarutanga pūnaha!
I roto i te ahurea DevSecOps, me mahi tahi te tere me te haumarutanga, ka whakaratohia e ngā ipu Docker te turanga mō te tuku pūmanawa tonu, aunoa, me te haumaru. Mā te ako he aha te ipu ka āwhina a Docker i ngā tīma ki te whakarite i ā rātou whāinga whanaketanga me te pumau me te manawanui mahi.
