I am deploying nodejs application on kubernetes, After deployment pod is up and running, but when I am trying to access the application through ingress it is giving 502 bad gateway error.
Dockerfile
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 . .

With ingress or even with the pod cluster ip I am not being able to access application it is throwing 502 bad gateway nginx
Issue got resolved, I am using SSL in my application as a result it was not re-directing with the given ingress url.
Need to add below annotation in ingress.yaml file.
nginx.ingress.kubernetes.io/ssl-passthrough: "true"
nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
