Ansible:考虑使用 'become' 、 'become_method' 和 'become_user' 而不是运行 sudo

Question

当我运行这个:
ansible host -u myuser -a "sudo su - otheruser -s /bin/bash"
我收到警告:

[WARNING]: Consider using 'become', 'become_method', and 'become_user' rather
than running sudo

host | SUCCESS | rc=0 >>

但是使用 become 等效于什么为 sudo su - otheruser -s /bin/bash ?

我试过:

ansible host -u myuser --become --become-user otheruser -a "/bin/echo hello"

但我得到:

host | FAILED! => {
    "changed": false,
    "module_stderr": "Shared connection to host closed.\r\n",
    "module_stdout": "sudo: a password is required\r\n",
    "msg": "MODULE FAILURE",
    "rc": 1
}

附言Ansible 版本:2.6.4

Answer 1

我必须指定 --become_method su .或者更具体地说 ansible host -u myuser --become-method su --become-user otheruser -a "/bin/echo hello"
附言我路过-a "/bin/echo hello" ，因为 ansible 期望在更改用户后运行一些命令。
