Question

我正在构建一个角色，我可能希望将其作为多个剧本的依赖项。我想支持：

clusterA.yml
- hosts:
  - clusterA
  roles:
  - clusterA

Vs的：

clusterB.yml
- hosts:
  - clusterB
  roles:
  - clusterB

在clusterA或clusterB meta / main.yml中，我可能有：

dependencies:
  - { role: commondependency }

好的，在设置公共依赖关系时，我想ssh-keys扫描集群中的其他主机。群集可以是clusterA，也可以是clusterB，也可以是clusterY。我可以找到大量这样的例子：

- name: Key Scan Cluster
  shell: ( ssh-keyscan {{item}} && cat /opt/commondependency/.ssh/known_hosts | sort | uniq ) > /opt/commondependency/.ssh/known_hosts
  with_items: hosts['clusterA']

但我真正想要的是：

- name: Key Scan Cluster
  shell: ( ssh-keyscan {{item}} && cat /opt/commondependency/.ssh/known_hosts | sort | uniq ) > /opt/commondependency/.ssh/known_hosts
  with_items: the hosts I am running a playbook on right now

Answer 1

我们转到http://docs.ansible.com/playbooks_variables.html底部提到的方式：

- name: Key Scan Cluster
  shell: ( ssh-keyscan {{item}} && cat /opt/commondependency /.ssh/known_hosts | sort | uniq ) > /opt/commondependency/.ssh/known_hosts
  with_items: "{{ansible_play_hosts}}"
