ansible - 使用 delegate_to 运行 adhoc wait_for

Question

我的 Makefile 有以下步骤

   create:
       do create stuff
       # extra ansible adhoc command to wait for ssh

   setup:
       do other stuff

我想在 do create stuff 之后添加一个步骤，等待所有主机都可以访问其 ssh 端口，但我不想提交一个额外的剧本来执行此操作:

  - hosts: all
    tasks:
      - name: wait for ssh port
        wait_for:
          host: '{{ ansible_ssh_host }}'
          port: 22
          timeout: 300
        delegate_to: localhost

我尝试使用一个临时命令来运行上面的命令，但使用本地操作

ansible all -i inventory -m local_action -a 'wait_for port=22 timeout=300'

但这不是正确的原因

ERROR! this task 'local_action' has extra params, which is only allowed in the following modules: command, win_command, shell, win_shell, script, include, include_vars, add_host, group_by, set_fact, raw, meta

来自评论:

• So you want to check whether all the target servers are pingable or not ? – Shasha99
• Not pingable. Ssh-able.

我不知道你为什么要使用 Ansible 来做这件事。这是一个简单的 bash 循环(添加一个外部循环来迭代您的主机):

for i in {1..30}; do
  ssh $host true 2> /dev/null
  if [ $? -eq 0 ]; then
    exit
  else
    sleep 10
  fi
done
