我正在尝试使用其文档中显示的示例来设置Traefik反向代理。当我尝试启动“whoami”服务时，出现以下错误：

Creating test_whoami_1 ... 

ERROR: for test_whoami_1  dictionary update sequence element #0 has length 22; 2 is required

我尝试使用带有以下代码的 Python JIRA 客户端：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from jira.client import JIRA

jira = JIRA(options={'server': 'http://server.atlassian.net'},
            basic_auth=('email@example.com', 'pass'))

projects = jira.projects()

for v in projects:
    print v

我收到以下错误：

Got recoverable error from GET https://server.atlassian.net/rest/api/2/serverInfo, will retry [1/3] in 17.5832343958s. Err: 401 Unauthorized

使用 python 2.7 (virtualenv)，使用pip install jira. 我尝试使用我的用户名和电子邮件，并且确定我的登录凭据是正确的（我可以使用我的浏览器使用相同的凭据登录而没有问题）。任何提示我做错了什么？

我正在尝试编写一个简单的 Ansible Playbook，请查看下面的片段。使用 Ansible 2.4.0.0、Ubuntu 17.04、Python 2.7.13。这是我第一次使用 Ansible 和 Playbooks，所以请不要太苛刻。我究竟做错了什么？

我在通过 Docker 注册表将n8n部署到 Heroku 时遇到问题，并且无法弄清楚我做错了什么。任何帮助将不胜感激。

手动配置 Postgres 版本 11：

heroku addons:create heroku-postgresql:hobby-dev --version=11 -a my-app

Dockerfile：

FROM n8nio/n8n

heroku.yml：

FROM n8nio/n8n

日志通过heroku logs --tail：

  #  - plan: heroku-postgresql:hobby-dev

  #    as: DATABASE
  config:
