在docker多阶段构建中,如何防止其他阶段与特定阶段并行运行? 我有一个多阶段的Dockerfile。其中一个阶段构建opencv堆栈。 FROM node:12.22.1 AS client_build
COPY client/package*.json .
RUN npm install
RUN npm run build
FROM pkg_builder AS open_cv_builder
ARG PYTHON_VERSION
RUN cd ~ && \
python${PYTHON_VERSION} -m pip install numpy==1.18.

im目前正在开发一个python脚本,该脚本可以执行数千次POST请求,将虚拟数据填充到数据库中。POST请求向后端发送一个字符串,将该字符串填充到数据库中。
前10000个请求运行良好,但随后出现了一个ConnectionError。
这是我的代码sqlfiller.py的简化实现。
import requests
url = "http://localhost:3100/api"
payload = "test"
#40 represents all business-days in two months
for i in range(40):
我有Django应用程序,它将芹菜用于异步任务。此外,我在本地使用RabbitMQ,但在Heroku上我尝试安装CloudAMQP插件。应用程序启动时没有任何错误,但是发送给芹菜的任何任务都会因错误而失败: Errno 111连接在这里被拒绝,这是heroku日志在开始时的样子:
heroku[celery.1]: Process exited with status 0
heroku[celery.1]: Starting process with command `celery worker -A mysite -l info --beat`

我正在将我在Django 2.2中的应用程序迁移到3.2版本,当通过测试时,它给出了以下错误,这似乎是框架固有的错误。应用程序运行得很好,但测试停止了。 python manage.py test --keepdb

我一直通过为我的Django应用程序使用PostGreSQL。最近,我开始看到以下问题:
...
File "/env/lib/python3.7/site-packages/django/utils/asyncio.py", line 26, in inner return func(*args, **kwargs)
File "/env/lib/python3.7/site-packages/django/db/backends/base/base.py", line 220, in ensure_connection self.
这是回溯(复制粘贴):
Traceback Switch to copy-and-paste view
/usr/local/lib/python2.6/dist-packages/django/core/handlers/base.py in get_response
response = middleware_method(request) ...
▶ Local vars
/usr/local/lib/python2.6/dist-packages/django/middleware/common.py in process_request
完全错误是:

在python2.7上运行版本为“0.4.25”的moto,我得到以下错误:NotImplementedError: The get_caller_identity action has not been implemented
import boto3

@mock_sts
def test_get_caller_identity():
sts = boto3.client("sts")

在Amazon Athena中执行两个请求之间是否有时间限制?例如,我从python代码发起一些请求,如下所示:
the request request1 at time t1
the request request2 at time t2
the request request3 at time t3
我的问题是,是否存在限制间隔
t1 and t2
t2 and t3
因为在27次请求之后,我的请求被取消或失败。
