Ke hoʻoholo ʻoe e kākau i kāu kaʻa ponoʻī no ka hopu ʻana i nā makau mai ka docker hub a i ʻole ke kākau inoa e hoʻohou hou / holo i nā pahu ma ka kikowaena, hiki iā ʻoe ke ʻike i ka Docker Cli pono, e kōkua i ka mālama ʻana i ka daemon Docker ma kāu ʻōnaehana.
No ka hana, pono ʻoe i ka mana Go ma lalo o 1.9.4
Inā ʻaʻole ʻoe i hoʻololi i nā modules, e hoʻokomo iā Cli me kēia kauoha:
go get github.com/docker/docker/clientHolo i kahi ipu
Hōʻike kēia hiʻohiʻona pehea e holo ai i kahi pahu me ka hoʻohana ʻana i ka Docker API. Ma ka laina kauoha e hoʻohana ʻoe i ke kauoha docker run, akā hiki iā mākou ke hoʻokō maʻalahi i kēia hana i kā mākou lawelawe.
