卡夫卡制作者不在码头集装箱工作

Question

我已经创建了一个简单的卡夫卡应用程序，发送信息给一个主题。当我在本地环境中运行它时，它工作得很好。但是，当我将它移动到Docker容器时，它无法连接到代理。我认为在容器网络设置中存在问题，但我无法解决。

应用程序代码：

from kafka import KafkaProducer

producer = KafkaProducer(
    bootstrap_servers='xxxxxxxxxx.mdb.yandexcloud.net:9091',
    security_protocol="SASL_SSL",
    sasl_mechanism="SCRAM-SHA-512",
    sasl_plain_password='xxxxxxxxxx',
    sasl_plain_username='xxxxxxxxxx',
    ssl_cafile="YandexCA.crt",
    api_version=(0,11,5))

producer.send('test_topic', b'test message')
producer.flush()
producer.close()

Dockerfile：

# For more information, please refer to https://aka.ms/vscode-docker-python
FROM python:3.10

# Keeps Python from generating .pyc files in the container
ENV PYTHONDONTWRITEBYTECODE=1

# Turns off buffering for easier container logging
ENV PYTHONUNBUFFERED=1

# Install pip requirements
COPY requirements.txt .
RUN python -m pip install -r requirements.txt

WORKDIR /app
COPY . /app

# Creates a non-root user with an explicit UID and adds permission to access the /app folder
# For more info, please refer to https://aka.ms/vscode-docker-python-configure-containers
RUN adduser -u 5678 --disabled-password --gecos "" appuser && chown -R appuser /app
USER appuser

# During debugging, this entry point will be overridden. For more information, please refer to https://aka.ms/vscode-docker-python-debug
CMD ["python", "app.py"]

所以它在终点站运行得很好，但在码头却失败了。是什么引起的？

Answer 1

所以问题就在密码里。有一些人物在逃避，就像：

ENV PASS=xxxxx\6xxxxx

当由env设置时，它正确工作，但是当设置在docker文件中时，它被转义了。所以在Dockerfile中，我是这样设置的：

ENV PASS="xxxxx\6xxxxx"

一切都开始运作了。
