What is the difference between exposed and published ports in Docker?
Exposed ports in Docker are ports that are available to be connected to from the outside world. Published ports on the other hand are ports that have been actively bound between the host machine and the Docker container. By publishing a port, you are exposing it to outside traffic in a secure way. Exposed ports can make vulnerable services accessible, while published ports are bound to a specific IP address and port, which ensures security and isolates it from the outside world.1. Expose a port when creating a container: Use the -p flag when running the docker container create command and specify the port you want to expose. For example, this command exposes port 80:
```
$ docker container create --name example-web -p 80:80 nginx
```
2. Expose a port on an existing container: Use the docker container update command and specify the port you want to use. For example, this command exposes port 80:
```
$ docker container update --expose 80 example-web
```Expose in Docker allows containers to communicate with the world outside the container. It publishes information about a container’s services (e.g. ports) to the host machine.
Expose in Kubernetes enables applications to provide information to the outside world. It creates an external endpoint for users to access the application, even if they are outside of the cluster. It is used to provide load balancing, service discovery, and service mesh.Expose 80 in Docker means that the container is listening to all incoming traffic on port 80. This is typically used when setting up a web server or other service that needs to be accessible from the public internet.
