Wait, why 8080? Isn't 80 the default for NGINX?

Hmm, the environment variable name seems a bit odd, but I guess it's a custom setting.

This looks straightforward, just need to make sure the namespace and container image are correct.

I know I need to use the `kubectl` command, but I’m uncertain if I should include the `--namespace` flag or just set it in the YAML file.

I practiced a deployment with multiple replicas, but I’m a bit confused about how to expose the port correctly.

This question feels similar to the practice one about creating a deployment, but I can't recall if I need to specify the namespace in the command.

I think I remember how to create a deployment, but I'm not sure about the exact syntax for setting the environment variable.

Hmm, this looks like a standard deployment creation task. I'll need to use the `kubectl create deployment` command and then set the appropriate flags for the namespace, name, replicas, image, and environment variable. I'm confident I can handle this, but I'll double-check the syntax just to be sure.

Okay, this seems pretty straightforward. I'll need to use the `kubectl create deployment` command, and then configure the deployment with the specified parameters. I'm a bit unsure about the environment variable syntax, but I'll look it up in the documentation to make sure I get it right.

Alright, let's do this. I'm going to create the deployment using the `kubectl create deployment` command, and then use the `--namespace`, `--replicas`, `--image`, and `--env` flags to configure it as required. Shouldn't be too tricky, as long as I get the details right.

Hmm, this looks straightforward enough. I'll need to use the `kubectl create deployment` command and specify the namespace, name, replicas, image, and environment variable. Shouldn't be too difficult, but I'll need to double-check the syntax.

Okay, let's see. I'll need to create a new deployment in the kdpd00201 namespace, with the name "frontend" and 4 replicas. The container image is lfccncf/nginx:1.13.7, and I'll need to set an environment variable of NGINX__PORT=8080 and expose that port.
