Ansible Tower 忽略了流水线
pipelining is being ignored by Ansible Tower
我正在尝试启用流水线，但无论我尝试什么，它都不起作用。
ansible.cfg内容：
[defaults]
transport = ssh
host_key_checking = false
retry_files_enabled = false
nocows=true
remote_user=ansible
# display_skipped_hosts = false
allow_world_readable_tmpfiles = True
warning = False
roles_path = ./roles
ansible_managed = Ansible managed: {file} modified on %Y-%m-%d %H:%M:%S by {uid} on {host}
callback_whitelist = profile_tasks
[privilege_escalation]
become_method = su
become_exe = 'sx su -'
[ssh_connection]
pipelining = true
ssh_args = -C -o ControlMaster=auto -o ControlPersist=600s -o ControlPath=/tmp/ansible-ssh-%%h-%%p-%%r
Ansible Tower 版本：3.4.1（由 Redhat 提供）
使用的 Ansible 环境版本：2.9、2.8 和 2.7
RHEL 6 上的 Ansible Tower 运行s 和我尝试针对的 VM 运行 该剧本在 RHEL 7 上。
我没有访问 Tower VM 的权限来检查配置。
这是我剧本的日志运行ning:

我原以为只会看到一个 SSH：EXEC 而没有 PUT。
难道我做错了什么？我确实尝试过 mitogen 并且它有效，除了 Become 部分，所以我不能使用它。我希望能够启用流水线。
另外要提的是，RHEL7 VM，剧本将在其中检查日期、写入文件并删除它，在 /etc/sudoers 中有这一行：Defaults !requiretty
我也尝试在每个任务中使用 vars 并设置 ansible_ssh_pipelining: true 但结果相同。
可以在 Tower 的更高级别禁用流水线吗？我累了，犯错了吗？我快要疯了...
原因是“su”被用作become_method。好像不支持流水线
代码中可以找到如下注释：
