使用Ansible创建领事集群的问题

Question

I'm trying to create a Consul cluster using Ansible and i'm using this example https://github.com/brianshumate/ansible-consul .i'm using the vagrant file to up 3 Ubuntu machines

the problem is that the task Install unzip package seem to always fail,and it gives this error message:

fatal: [consul1.consul -> localhost]: FAILED! => {"changed": false, "msg": "Could not detect which package manager to use. Try gathering facts or setting the \"use\" option."}

Ansible seem unable to recognize the package manager,even though ansible localhost -m setup | grep mgr ansible localhost -m setup | grep mgr shows that the variable ansible_pkg_mgr has the value apt

i'm not sure what could be the source of the problem.i tried upping 3 debian machines and i still have the same problem.

UPDATE: here's the task file for consul

The problem is with the Alpine package Manager,somehow it seem to cause an error with Ubuntu,so all what i did is use Apt instead of Apk.

here's the new version of the task file
