这个 Ansible 角色已创建并这个 .travis.yml已用作示例来测试该角色。除 sensu-client 外,所有服务均能启动。
尝试解决问题
为了解决问题向 travis 添加了一个调试步骤。构建完成时抛出了以下错误:
The command "sudo docker exec "$(cat ${container_id})" ansible-playbook /etc/ansible/roles/role_under_test/tests/test-${SITE}.yml | grep -q 'changed=0.*failed=0' && (echo 'Idempotence test: pass' && exit 0) || (echo 'Idempotence test: fail' && exit 1)
" exited with 1.
0.07s$ sudo docker exec --tty "$(cat ${container_id})" env TERM=xterm sudo systemctl status sensu-client.service -l

当 ansible 角色部署在远程系统上时,sensu-client 会启动,但它在 Travis 上会失败,尽管其他服务可以启动。
答案1
简洁的
initscripts
缺少软件包。这是在将本地系统上的文件与 Travis 使用的 docker 容器中的文件进行比较后发现的。/etc/init.d
查询后,/etc/init.d/functions
清楚了需要安装哪个软件包。
详细
似乎缺少文件/etc/init.d
,即:
Aug 08 00:18:19 c6354976113c sensu-client[1534]: /etc/init.d/sensu-service:
line 71: /etc/init.d/functions: No such file or directory
是真的吗?为了检查是否添加了另一个调试步骤:ls /etc/init.d
。结果如下:
$ sudo docker exec --tty "$(cat ${container_id})" env TERM=xterm ls /etc/init.d
README sensu-api sensu-client sensu-server sensu-service uchiwa
functions
确实失踪了。这个帖子表示initscripts
需要安装。当该包已添加到 Dockerfile然后构建再次运行它成功了。
