如何通过 Test-Kitchen 运行 对 ansible 角色进行幂等测试?
How to run idempotence test for ansible role via Test-Kitchen?
使用 Travis 非常简单-CI:
# Run the role/playbook again, checking to make sure it's idempotent.
- >
ansible-playbook -i tests/inventory tests/test.yml --connection=local --sudo --extra-vars "take_ownership_of_tmp=$OWN_TMP"
| grep -q 'changed=0.*failed=0'
&& (echo 'Idempotence test: pass' && exit 0)
|| (echo 'Idempotence test: fail' && exit 1)
但我不能使用 Travis,因为我需要在 Debian 系统上测试我的角色。我将 Test-Kitchen 与 ansible_playbook provisioner 一起使用。
例如:
我的.kitchen.yml
---
driver:
name: vagrant
provisioner:
name: ansible_playbook
hosts: test-kitchen
ansible_verbosity: 2
ansible_verbose: true
require_ansible_repo: false
require_chef_omnibus: false
require_ansible_omnibus: true
require_chef_for_busser: false
ansible_omnibus_url: https://raw.githubusercontent.com/neillturner/omnibus-ansible/master/ansible_install.sh
platforms:
- name: debian-6.0.10-64-nocm
driver_config:
customize:
memory: 1024
cpus: 2
box: puppetlabs/debian-6.0.10-64-nocm
box_url: https://atlas.hashicorp.com/puppetlabs/boxes/debian-6.0.10-64-nocm/versions/1.0.2/providers/virtualbox.box
suites:
- name: default
verifier:
ruby_bindir: '/usr/bin'
测试剧本(test/integration/default/default.yml)非常简单
---
- hosts: all
roles:
- preconf
vars:
#some vars here
我可以向 default.yml 添加第二次调用 preconf 角色,但这没有帮助。
一个电话厨房returns我改变了一些项目:
PLAY RECAP ********************************************************************
localhost : ok=12 changed=8 unreachable=0 failed=0
但是有两个调用它 returns 项目的总和而不是两个单独的结果
PLAY RECAP ********************************************************************
localhost : ok=24 changed=10 unreachable=0 failed=0
那么,我如何才能 运行 剧本第二次检查幂等性测试的结果?
自己通过 BATS 测试解决了问题:
#!/usr/bin/env bats
#
#
# Idempotence test
#
@test "Second run should change nothing" {
run bash -c "ansible-playbook -i /tmp/kitchen/hosts /tmp/kitchen/default.yml -c local | grep -q 'changed=0.*failed=0' && exit 0 || exit 1"
[ "$status" -eq 0 ]
}
UPD 服务器规格变体:
describe command('ansible-playbook -i /tmp/kitchen/hosts /tmp/kitchen/default.yml -c local') do
its(:stderr) { should match /changed=0.*failed=0/ }
its(:exit_status) { should eq 0 }
end
两个 ansible_playbook
and ansible_push
厨房供应商现在都支持 idempotency_test
参数,它实际上是第二次运行剧本并检查 failed
或 changed
任务。
您可以像这样简单地将 idempotency_test: true
添加到您的 .kitchen.yml
