我正在 kubernetes 上部署 nodejs 应用程序，在部署 pod 启动并运行后，但是当我尝试通过入口访问应用程序时，它会给出 502 bad gateway 错误。
Dockerfile

# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm ci --only=production
# Bundle app source
COPY . .
EXPOSE 3123

使用入口，甚至使用 pod 集群 ip，我都无法访问应用程序，它会抛出 502 bad gateway nginx
