Inputs

    
match:
    default: all
    description:
    - The I(match) argument is used in conjunction with the I(wait_for) argument to specify
      the match policy.  Valid values are C(all) or C(any).  If the value is set to C(all)
      then all conditionals in the I(wait_for) must be satisfied.  If the value is set
      to C(any) then only one of the values must be satisfied.

retries:
    default: 10
    description:
    - Specifies the number of retries a command should by tried before it is considered
      failed.  The command is run on the target device every retry and evaluated against
      the I(wait_for) conditionals.

commands:
    description:
    - The commands to send to the remote HUAWEI CloudEngine device over the configured
      provider.  The resulting output from the command is returned. If the I(wait_for)
      argument is provided, the module is not returned until the condition is satisfied
      or the number of I(retries) has been exceeded.
    required: true

interval:
    default: 1
    description:
    - Configures the interval in seconds to wait between retries of the command.  If the
      command does not pass the specified conditional, the interval indicates how to long
      to wait before trying the command again.

wait_for:
    description:
    - Specifies what to evaluate from the output of the command and what conditionals
      to apply.  This argument will cause the task to wait for a particular conditional
      to be true before moving forward.   If the conditional is not true by the configured
      retries, the task fails.  See examples.
