部署在 Kubernetes 集群上的 Nodejs 应用程序上的 502 Bad gateway

Question

我正在 kubernetes 上部署 nodejs 应用程序，在部署 pod 启动后 运行，但是当我尝试通过入口访问应用程序时，出现 502 bad gateway 错误。

Docker 文件

FROM node:14

# 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
CMD [ "node", "index.js" ]

使用入口或什至使用 pod 集群 ip 我无法访问它正在抛出 502 错误网关 nginx 的应用程序

Answer 1

问题已解决，我在我的应用程序中使用了 SSL，因此它没有使用给定的入口重定向 url。

需要在 ingress.yaml 文件中添加以下注释。

nginx.ingress.kubernetes.io/ssl-passthrough: "true"
nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
