podman injin kwantena ne wanda zai iya zama maye gurbin Docker. Wannan injin ɗin kamfanin Red Hat ne ya haɓaka shi (wanda mallakar IBM ne a yanzu) kuma yana da niyyar motsa shi da kaɗan kaɗan. Shin zai yi nasara? To zamu gani…
El bude tushen aiki yana da sauƙin amfani, wanda shine babban zane. Wannan shine sauƙin cewa akwai labarin Dan Walsh, injiniyan Red Hat, inda yake nuna matakan ƙaura don maye gurbin Docker da Podman, kuma waɗannan sune:
dnf install -y podman alias docker=podman
Kuma a ƙarƙashin wannan bayanin ya ƙare da cewa «Akwai wasu tambayoyi?»Da dan raha saboda yadda yake da sauki ...
Bayan wannan, idan kun riga kun saba amfani da Docker ba lallai bane ku damu da yawa dokokin, tunda Podman yayi amfani da irin waɗannan don yawancin. Wato, idan za a gudanar da akwati dole ne a yi amfani da shi Docker gudu, don yin shi tare da wannan aikin dole ne kuyi amfani dashi podman gudu. Yana da sauƙin tunawa da zaɓuɓɓukan.
Da kyau, ya zuwa yanzu komai yayi kama. Duk ayyukan biyu suna da kyau, buɗaɗɗen tushe, suna aiki tare da kwantena, suna da sauƙi, suna amfani da tsari iri ɗaya, da dai sauransu. Amma to? Menene Podman ya yi don ya cancanci samun shi? Da kyau, ɗayan bambance-bambancen shine ba bisa aljanu ba (ayyuka a cikin * nix duniya).
Kamar yadda kuka sani, Docker yana da daemon hade da shi. Wannan aljanin babu kamarsa kuma yana da tsakiya, wanda yake nufin cewa da zarar kunyi amfani da kwantena, rikitarwarsa zata girma kuma ta zama nauyi da nauyi. Abin da ya sa Red Hat ya yanke shawarar ƙirƙirar wannan kayan aikin don gyara wannan rashin dacewar.
A cikin Podman suna da abubuwan da aka rarraba don gudanar da kwantena kuma don haka guje wa faɗakar daemon kamar yadda yake faruwa a Docker. Ana amfani da waɗancan ɗaiɗaikun mutanen lokacin da ake buƙata, wanda zai haifar da ƙarancin amfani.
Baya ga wannan fa'idar, tana da wata babbar fa'ida. Podman na iya sarrafa kwantena kamar yadda Docker yake, amma kuma zaka iya yin shi da Pods, wato, mashinan da ake amfani da su a Kubernetes. Babban mahimmancin banbanci tsakanin akwati da kwalliya shine kowane kwafon na iya ƙunsar akwati fiye da ɗaya.
Wancan akwati da mai kula da kwantena za su ci nasara cewa, bisa manufa, ya fi inganci a cikin albarkatu, yana ba da damar keɓe duka shirye-shiryen da aikace-aikacen tsarin ta hanyar da ba ta dace ba kuma a ƙarshe, dole ne a shigar da shi a cikin Ayyuka daban-daban Tsarin tsarin ba tare da hakan yana shafar gina kwantena, aiwatarwa da rarrabawa.
PS: kodayake bashi da mahimmanci, zaku iya ƙara kayan aikin zane wanda zai ba ku damar aiwatar da ayyuka iri ɗaya kamar a cikin na'urar wasan bidiyo.
