Resolution for manifest configuration errors

Step 1: Check port and selector configurations

- The values or names mentioned in the following are only for illustration purpose.
- Specify your host name, service name and app.kubernetes.io/name.

Open the Service and Deployment configurations.
Make sure the correct Application port is mentioned as targetPort.
Ensure that the value of targetPort matches with the application port that is exposed in the container. You may find the port number within the dockerfile that is used to build the container image. For example:
```
# syntax=docker/dockerfile:1

FROM node:18-alpine
WORKDIR /app
COPY . .
RUN yarn install --production
CMD ["node", "src/index.js"]
EXPOSE 3000
```
Dockerfile can be found within your application code repository. For example: https://sgts.gitlab-dedicated.com/wog/gvt/cstack/groups/tenants/internet/gvt-cstack-alex/apps/go-demo

Make sure the same value is specified for app.kubernetes.io/name in both the configurations.
Example of app.kubernetes.io/name in Service configuration.
Example of app.kubernetes.io/name in Deployment configuration.

Step 2: Check port and service names

Open the Service and Ingress configurations.
Make sure the same port name is mentioned in both the configurations.
Example of port name in Service configuration.
Example of port name in Ingress configuration.
Make sure the same service name is mentioned in both the configurations.
