Travis CI + docker-compose + ansibleでzabbixモジュールのCIをやる

Last updated at Posted at 2019-05-26

Travis CIとdocker-composeとansibleを使ってzabbixのモジュールをテストを自動化してみました。

やりたかったこと

  • Python2.7、3.5、3.6、3.7ごとのAnsible動作試験をしたかった
  • Zabbixの各バージョンでAnsibleのZabbixモジュールの動作試験をしたかった
  • Zabbixの複数バージョンを使うのでコンテナを使いたかった(バージョンごとにVMのインスタンスを立てたくなかった)

作成したファイル

今回作ったファイルは以下に保存されています。

https://github.com/sky-joker/travis-ci-zabbix-test

travis.yml

travis.yml は以下のように書きました。
composeをインストールしてpipでansibleとzabbix-api(zabbixモジュールを動かすのに必要)をインストールしてコンテナを立ち上げzabbixの起動を確認するPlaybookを実行し、各コンテナが起動したらlocaleを設定してからモジュールのテストPlaybookを実行しています。
テストするpythonのバージョンは 2.7 3.5 3.6 3.7 を指定しています。(3.8は無かった)

language: python
python:
  - "2.7"
  - "3.5"
  - "3.6"
  - "3.7-dev"

services:
  - docker

install:
  - sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
  - sudo chmod +x /usr/local/bin/docker-compose
  - pip install ansible zabbix-api
  - sudo docker-compose up -d
  - ansible-playbook zabbix_startup_check.yml
  - sh set_zabbix_locale.sh

script:
  - ansible-playbook test_zabbix_group.yml

docker-compose.yml

ここでは、zabbix3.0からzabbix4.2までのコンテナ（公式イメージ）が起動するように定義しました。
アクセスするポートごとにzabbixのバージョンを分けました。

zabbix_startup_check.yml

これは、compose実行後にzabbixの起動を確認するPlaybookです。
以下のように書いています。

---
- name: zabbix startup check
  hosts: localhost
  gather_facts: no
  tasks:
    - name: check login to zabbix.
      uri:
        url: "http://127.0.0.1:{{ item }}/api_jsonrpc.php"
        method: POST
        body:
          jsonrpc: "2.0"
          method: "user.login"
          params:
            user: "admin"
            password: "zabbix"
          id: "1"
        body_format: json
        status_code: 200
      retries: 60
      delay: 5
      until: result is defined and 'json' in result and 'result' in result.json
      register: result
      loop:
        - 8030
        - 8032
        - 8034
        - 8040
        - 8042

set_zabbix_locale.sh

デフォルトだと日本語などが使えない（英語のみ）のでコンテナ内でlocaleを設定します。

#!/bin/sh

for c in $( docker ps --format '{{.Names}}' | grep web ) ; do
    docker exec $c localedef -f UTF-8 -i zh_CN zh_CN
    docker exec $c localedef -f UTF-8 -i cs_CZ cs_CZ
    docker exec $c localedef -f UTF-8 -i fr_FR fr_FR
    docker exec $c localedef -f UTF-8 -i he_IL he_IL
    docker exec $c localedef -f UTF-8 -i it_IT it_IT
    docker exec $c localedef -f UTF-8 -i ko_KR ko_KR
    docker exec $c localedef -f UTF-8 -i ja_JP ja_JP
    docker exec $c localedef -f UTF-8 -i nb_NO nb_NO
    docker exec $c localedef -f UTF-8 -i pl_PL pl_PL
    docker exec $c localedef -f UTF-8 -i pt_BR pt_BR
    docker exec $c localedef -f UTF-8 -i pt_PT pt_PT
    docker exec $c localedef -f UTF-8 -i ru_RU ru_RU
    docker exec $c localedef -f UTF-8 -i sk_SK sk_SK
    docker exec $c localedef -f UTF-8 -i tr_TR tr_TR
    docker exec $c localedef -f UTF-8 -i uk_UA uk_UA
    docker exec $c apachectl -k graceful
done

test_zabbix_group.yml

実際に実行するテストは以下のように書いています。

---
- name: zabbix grpuo module test.
  hosts: localhost
  gather_facts: no
  vars:
    zabbix_server: "http://127.0.0.1"
    zabbix_user: "admin"
    zabbix_passwd: "zabbix"
    zabbix_ports:
      - 8030
      - 8032
      - 8034
      - 8040
      - 8042
    zabbix_groups:
      - Example1
      - Example2
  tasks:
    - name: create of zabbix host group.
      zabbix_group:
        server_url: "{{ zabbix_server }}:{{ item }}"
        login_user: "{{ zabbix_user }}"
        login_password: "{{ zabbix_passwd }}"
        validate_certs: no
        host_groups: "{{ zabbix_groups }}"
        state: present
      loop: "{{ zabbix_ports }}"

    - name: delete of zabbix host group.
      zabbix_group:
        server_url: "{{ zabbix_server }}:{{ item }}"
        login_user: "{{ zabbix_user }}"
        login_password: "{{ zabbix_passwd }}"
        validate_certs: no
        host_groups: "{{ zabbix_groups }}"
        state: absent
      loop: "{{ zabbix_ports }}"
