 Yadda ake gudanar da kwantena na Docker

El daemon Docker zai riga yana aiki. Yanzu, don gudanar da akwatin mu na farko, zamuyi amfani da umarnin:

Kamar yadda aka ambata a sama, akwatinan Docker ana amfani dasu ta tsoho akan cibiyar su. Akwai hotunan daruruwa ko dubbai, don haka za mu yi bincike don aiwatar da wanda yake sha'awar mu. Misali, umarnin bincike don nemo hoto game da Linux Mint, ɗayan shahararrun rabarwar Ubuntu, zai zama mai zuwa:

sudo docker search "linux mint"

Binciken da ya gabata zai nuna mana wani abu kamar haka:

Lokacin neman hoto don gudanar da akwati, koyaushe dole muyi amfani da wanda ke da shafi "Yayi" ko "Official", wanda ke nufin cewa ya fito ne daga aikinku ba daga kowane mutum bane kawai. A cikin jerin da suka gabata babu wani na hukuma, amma akwai na Ubuntu. Zamu gudanar da akwati ta amfani da hoton Ubuntu na hukuma (daga na baya) tare da umarni mai zuwa:
