Beka umfanekiso weDocker kwiDokku usebenzisa iAnsible

Isingeniso

Kutshanje ndifunde "ngepokotho" yePaaS efana neHeroku enegama elicacileyo-iDokku. Nditsalwe kakhulu kukukwazi ukongeza ngokulula isatifikethi kwisicelo kunye ne-vhost ngaphandle kwebhokisi, ngoko ke ndagqiba ekubeni ndidlulisele imifanekiso yam yedocker kwiDokku. Enyanisweni, ndadana ukuba i-Dokku ayinayo imiyalelo efana ne-Heroku

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

Kukho iqela tags ekuvumela ukuba usebenzise imifanekiso, kodwa umfanekiso ngokwawo kufuneka ube sele ukwinginginya ngalo mzuzu. Ngamanye amazwi, ukuze ukhuphe umfanekiso wendawo osanda kuwenza, kufuneka uqale uwukhuphele kumamkeli.

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

Ndiqhelene ne-Ansible kwaye ndidale imibhobho yokuhanjiswa kwe-backend elula ngayo, ngoko ke ukhetho belulula. Ewe, ndingadinwa kwaye ndibhale iplagin ye-dokku, kodwa hayi, hayi ngoku.

Incwadi yokudlala

Le ncwadi yokudlala igcina umfanekiso wendawo, ikopishe kumamkeli, iwubuyisele kwaye iwubeke kwi-dokku. Iposwe kwi-Gitlab repo. Kusekho indawo eninzi yokuphucula.

push-image.dokku.yml

push-image.dokku.yml

---
  - name: "DEPLOY APP '{{ appname }}' TO DOKKU"
    hosts: dokku_hosts
    remote_user: root
    gather_facts: false
    vars:
      tarname: "{{ appname }}__{{ image }}.tar"
      upload_dir: "/usr/local/src"
      upload_path: "{{ upload_dir }}/{{ tarname }}"
      apptag: "{{ upload_tag | default('latest') }}"
      dokku_image: "dokku/{{ appname }}:{{ apptag }}"

    tasks:
      - name: "Archive '{{ image }}' to upload"
        register: env
        delegate_to: localhost
        shell: 
          cmd: docker image save -o "./{{ tarname }}" {{ image }}

      - name: "Upload image '{{ image }}' to dokku at '{{ inventory_hostname }}'"
        register: upload
        copy:
          src: "./{{ tarname }}"
          dest: "{{ upload_path }}"

      - name: "Log - Upload result"
        debug:
          var: upload.dest

      - name: "Restore uploaded docker image"
        register: restore
        shell:
          cmd: docker image load -i "{{ upload_path }}"

      - name: "Log - Restore image"
        debug:
          var: restore.stdout_lines

      - name: "Retag image to '{{ dokku_image }}'"
        shell: 
          cmd: docker tag "{{ image }}" "{{ dokku_image }}"

      - name: "Create dokku tag for '{{ dokku_image }}'"
        shell: 
          cmd: dokku tags:create "{{ appname }}" "{{ apptag }}"

      - name: "Release '{{ appname }}'"
        register: release
        shell: 
          cmd: dokku tags:deploy "{{ appname }}" "{{ apptag }}"  

      - name: "Log - Release"
        debug:
          var: release.stdout_lines  

kucingelwa ukuba i-ansible sele ifakiwe kumatshini wendawo kunye ne-dokku kumamkeli

Sebenzisa ngolu hlobo

ansible-playbook push-image.dokku.yml -i some_inventory -e "appname=DOKKU_APP_NAME image=DOCKER_IMAGE"
