Ho amohela Kopo ho Sebelisa Lijana tsa Docker
Ts'ebeliso ea ts'ebeliso ho IOS XR e ts'ehetsa lijana tsa docker. U ka iketsetsa setshelo sa hau ho IOS XR u sebelisa docker, 'me u amohela lits'ebetso ka har'a setshelo. Lisebelisoa li ka ntlafatsoa ho sebelisoa kabo ea Linux efe kapa efe. Sena se loketse lits'ebetso tse sebelisang lilaebrari tsa sistimi tse fapaneng le tse fanoeng ke motso oa IOS XR file tsamaiso. Cisco NCS 540 e ts'ehetsa feela ts'ebeliso ea lits'ebetso tse thehiloeng ho docker.
Docker-Based Container Application Hosting
Karolo ena e hlahisa mohopolo oa ts'ebeliso ea ts'ebeliso ea setshelo mme e hlalosa ts'ebetso ea eona. Ho amohela kopo ea Container ho etsa hore ho khonehe hore likopo li amoheloe tikolohong ea tsona le sebaka sa ts'ebetso (sebaka sa mabitso) ka har'a setshelo sa Linux ho Cisco IOS XR. Moetsi oa kopo o na le taolo e felletseng holim'a tikoloho ea nts'etsopele ea kopo, mme a ka sebelisa khetho ea khetho ea Linux. Likopo li arohane le mekhoa ea lifofane tsa taolo ea IOS XR; leha ho le joalo, ba ka hokela marang-rang kantle ho XR ka li-interfaces tsa XR GigE. Lisebelisoa li ka fihlella habonolo sebakeng sa heno file litsamaiso tsa IOS XR.
Ho sebelisa Docker bakeng sa Likopo tsa Ho amohela ho Cisco IOS XR
Docker ke setshelo se sebelisetsoang ho amohela lits'ebetso ho Cisco IOS XR. Docker e fana ka ho itšehla thajana bakeng sa lits'ebetso tsa ts'ebeliso ho tsoa lits'ebetsong tse teng tsa moamoheli ho XR ka ho sebelisa libaka tsa mabitso tsa marang-rang a Linux.
Tlhokahalo ea Docker ho Cisco IOS XR
Docker e fetoha mohlala oa ho paka o ratoang ke indasteri bakeng sa lits'ebetso sebakeng sa virtualization. Docker e fana ka motheo oa ho iketsetsa tsamaiso ea potoloho ea bophelo ba ts'ebeliso. Docker e latela mokhoa o hlophisitsoeng o nang le setšoantšo sa motheo ka tlase se tšehetsang likarolo tsa lits'ebetso ka holimo. Litšoantšo tsa motheo li fumaneha phatlalatsa sebakeng sa polokelo, ho itšetlehile ka mofuta oa kopo eo u batlang ho e kenya ka holimo. O ka thetsa litšoantšo tsa docker ka ho sebelisa index ea docker le registry. Docker e fana ka ts'ebetso e ts'oanang ea git bakeng sa ho nts'etsapele lits'ebetso tsa setshelo mme e ts'ehetsa mochini oa "ntlafatso e nyane", moo ho ntlafatsoang phapang ea khoutu ea mohloli, e lebisang ntlafatsong e potlakileng. Docker e boetse e fana ka mochini oa "khoasolla o mosesaane", moo lits'ebetso tse ncha li jarollotsoeng kapele ka lebaka la ho arolelana likarolo tse tloaelehileng tsa li-docker lipakeng tsa lijana tse ngata tsa docker. Karolelano ea likarolo tsa li-docker lipakeng tsa lijana tse ngata tsa li-docker e lebisa tlhokomelong e tlase ea lijana tsa docker ho XR.

- Sebaka sa boema-kepe file polokelong ea mohloli e sebelisoa ho aha binary ea kopo file mochining oa hau oa (docker engine build) o amohelang.
- Sesebelisoa sa binary file e sutumelletsoa ho registry ea litšoantšo tsa docker.
- Sesebelisoa sa binary file e huleloa ho ngoliso ea litšoantšo ea li-docker ebe e kopitsoa ka sejaneng sa docker ho XR (moamoheli oa sepheo sa li-docker engine).
- Sesebelisoa se hahiloe mme se ts'oaroa ka har'a setshelo sa docker ho XR.
Ho nchafatsa likopo ho lijana tsa Docker

- Ntlafatso ea ts'ebeliso e hlahisoa joalo ka ntlafatso ea libs file (ntlafatso ea delta file) ebe o sutumelletsa ho registry ea litšoantšo tsa docker.
- Ntlafatso ea delta file (e nang le phapang feela ea khoutu ea kopo) e huloa ho tsoa ho ngoliso ea litšoantšo ea li-docker ebe e kopitsoa ho lijana tsa docker ho XR (moamoheli oa sepheo sa enjine ea docker).
- Li-container tsa docker li qala hape ka ntlafatso ea delta file.

Ho lokisa Docker e nang le li-VRF tse ngata
Karolo ena e hlalosa kamoo o ka hlophisang Docker e nang le li-VRF tse ngata ho Cisco IOS XR. Bakeng sa tlhahisoleseling mabapi le ho lokisa li-VRF tse ngata, bona Configuring Multiple VRFs for Application Hosting sehlooho.
Tlhophiso
Sebelisa mehato e latelang ho theha le ho tsamaisa Multi-VRF Docker ho XR.
- Theha Multi-VRF Docker e nang le litokelo tsa NET_ADMIN le SYS_ADMIN.
Ho e latelang example, sejana sa Docker se nang le li-VRF tse tharo (e mosehla, o moputsoa, le botala) sea hlahisoa. Example nka hore setšoantšo sa "multivrfimage" se fetileng se kentsoe ho sebelisoa taelo ea ho kenya sephutheloana sa appmgr.
Hlokomela:- Ho phahamisa litaba tsohle tsa /var/run/netns ho tloha moamoheli ho ea ho Docker ha ho khothalletsoe, hobane e beha litaba tsa marang-rang tse tsamaellanang le XR le sefofane sa tsamaiso ea sistimi ho Docker.
- Ha ua lokela ho hlakola VRF ho Cisco IOS XR ha e sebelisoa ho Docker. Haeba VRF e le 'ngoe kapa ho feta e hlakoloa ho XR, Multi-VRF Docker e ke ke ea hlahisoa
- Netefatsa haeba multi-VRF Docker e kentsoe ka katleho.
- Hokela ho setshelo sa multi-VRF Docker ka ho etsa taelo e latelang.
Router# appmgr e sebelisa lebitso la multivrfcontainer1 docker-exec-cmd /bin/bash/
Ka ho sa feleng, Docker e kentsoe sebakeng sa mabitso sa lefatše-vrf ho Cisco IOS XR. - Netefatsa hore na li-VRF tse ngata lia fumaneha ho tsoa ho Docker.
U atlehile ho qala Multi-VRF Docker ho Cisco IOS XR.
