Eziokwu ghọrọ otu n'ime ndị kasị ewu ewu Njikwa nhazi usoro. Mgbe Uhie okpu zụtara na 2015 nọmba sonyere oru ngo gafere puku kwuru puku na Ansible aghọọla eleghị anya nke kacha eji ebunye ọrụ na usoro nhazi. Ngwa ya dịgasị iche iche dị oke egwu.

Enwere ike na-arụ ọrụ maka njikọ SSH na ndị ọbịa dịpụrụ adịpụ. Ọ na-emepe nnọkọ SSH, banye, depụta koodu Python na netwọk wee dee ya na faịlụ nwa oge dị iche. Mgbe nke ahụ gasịrị, ọ na-agba faịlụ a na igwe dịpụrụ adịpụ. Usoro ọrụ a dum dị ogologo ma na-agwụ ike, yabụ enwere ụzọ dị iche iche iji bulie ya.

Otu n'ime ụzọ ndị a bụ SSH pipeline nke na-enye gị ohere iji otu nnọkọ SSH mee ntụziaka, kama ịmepe nnọkọ ọhụrụ oge ọ bụla, nke nwere ike ịzọpụta anyị ọtụtụ oge. (Cheta naanị ịgbanyụ requiretty ntọala maka sudo n'ime gị /etc/sudoers faịlụ na igwe dịpụrụ adịpụ)

Ụzọ ọhụrụ a ga-esi mefefe ihe ga-ekwe omume bụ ọba akwụkwọ Python nke a na-akpọ Mitogen. Ọ bụrụ na onye ọ bụla anụbeghị maka ya, m ga-akọwa nkenke ọrụ ya. Ọ na-enye ohere igbu ngwa ngwa nke koodu Python na igwe dịpụrụ adịpụ, yana ike bụ naanị otu ihe atụ nke ojiji. Mitogen na-eji ọkpọkọ UNIX na igwe dịpụrụ adịpụ ma na-ebufe koodu Python nke ejiri zlib abịakọta ma tinye ya na pickle. Nke a na-enyere aka imezu ya ngwa ngwa ma chekwaa okporo ụzọ. Ọ bụrụ na ị nwere mmasị na nkọwa zuru ezu karị, ọ kacha mma ịgụ banyere ya na ibe "Ka o si arụ ọrụ". Mana taa, anyị ga-elekwasị anya naanị ka ụlọ akwụkwọ ahụ si arụ ọrụ na Ansible.

Mitogen n'ọnọdụ ụfọdụ nwere ike mee ka koodu nwere ike mee ngwa ngwa ọtụtụ oge ma belata oriri okporo ụzọ. Ka anyị lelee okwu ikpe ndị kacha ewu ewu wee hụ etu ọ na-enyere anyị aka.

Ugbu a enwere ụzọ abụọ nhata - ma hazie nhọrọ na faịlụ nhazi ansible.cfg, ma ọ bụ tọọ mgbanwe gburugburu ebe dị mkpa.

Ka anyị chee na ụzọ Mitogen arụnyere ga-abụ /usr/lib/python2.7/site-packages/ansible_mitogen/plugins/strategy. Mgbe ahụ:
