Name flag not working

[Steve Groom]

I do not get the expected Name: MyName at the beginning of the whoami http response.

I am testing a complex traefik scenario and have multiple whoami containers running and want to tag each one clearly with the Name option.

docker run -d -P --name whoami -e name="MyName" traefik/whoami

curl 127.0.0.1:59707
Hostname: f98a3f6efd8a
IP: 127.0.0.1
IP: 172.17.0.2
RemoteAddr: 172.17.0.1:39884
GET / HTTP/1.1
Host: 127.0.0.1:59707
User-Agent: curl/7.68.0
Accept: */*

In app.go:

207
208	if name != "" {
209		_, _ = fmt.Fprintln(w, "Name:", name)
210	}
211
212	hostname, _ := os.Hostname()
213	_, _ = fmt.Fprintln(w, "Hostname:", hostname)

$ docker run --help
Usage:  docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

Run a command in a new container

Options:
...
  -e, --env list                       Set environment variables
...

the env var for the name is WHOAMI_NAME.

$ docker run -d -p 80:80 --name whoami -e WHOAMI_NAME="MyName" traefik/whoami
$ curl localhost:80    
Name: MyName
Hostname: d306b50f3fc9
IP: 127.0.0.1
IP: 172.17.0.2
RemoteAddr: 172.17.0.1:50208
GET / HTTP/1.1
Host: localhost
User-Agent: curl/7.83.1
Accept: */*

If you want to use the CLI flags:

$ docker run -d -p 80:80 --name whoami traefik/whoami --name=MyName
$ curl localhost:80 
Name: MyName
Hostname: 72a4803cdf7a
IP: 127.0.0.1
IP: 172.17.0.2
RemoteAddr: 172.17.0.1:38316
GET / HTTP/1.1
Host: localhost
User-Agent: curl/7.83.1
Accept: */*

I suggest the README.md have a better example:

replace

docker run -d -P --name iamfoo traefik/whoami

with

docker run -d -P --name containername traefik/whoami --name reportedname
