Tu'u le ata o le Docker i le Dokku e fa'aaoga ai le Ansible

Folasaga

Na ou aʻoaʻoina talu ai nei e uiga i se "taga" PaaS tutusa ma Heroku ma se igoa manino - Dokku. Sa ou matua tosina lava i le mafai ona faigofie ona faaopoopo se tusi faamaonia i le talosaga ma vhost mai le pusa, o lea na ou filifili ai e faʻafeiloaʻi aʻu ata faʻailoga i Dokku. E moni, sa ou le fiafia ona e leai ni poloaiga a Dokku e tutusa ma Heroku

dokku container:push
dokku container:release
// Очень было бы удобно, но еще нет :(

E iai le au tags lea e mafai ai ona e faʻapipiʻi ata, ae o le ata lava ia e tatau ona i ai i luga o le talimalo i le taimi nei. I se isi faaupuga, ina ia mafai ona taʻavale le ata faʻapitonuʻu na e faia, e tatau ona e kopi muamua i le talimalo.

tags:create <app> <tag>                        # Add tag to latest running app image
tags:deploy <app> <tag>                        # Deploy tagged app image
tags:destroy <app> <tag>                       # Remove app image tag

Ou te masani i le Ansible ma ua ou faia foʻi ni paipa faʻapipiʻi pito i tua, o lea na faigofie ai le filifiliga. Ioe, e mafai ona ou vaivai i ai ma tusi se plugin mo dokku, ae leai, e le o le taimi nei.
