Use wget --post-data "xxx" -q $URL to make a POST request to URL with xxx as the post data.

i just have the same problem as you so i decided to create minimum image from alpine that do lot more than busy box and less than ubuntu https://hub.docker.com/r/prima101112/palugada

you could do curl traceroute or even vim to edit inside pods or container

or if you want to still go with busybox usually i will go

kubectl exec -it busybox -- wget {url}
kubectl exec -it busybox -- cat index.html

that command will show the response

hope this will help

busybox has wget but this limited and unsuitable for posting. You can combine busybox with netcat (or nc) for achieving the result. You only need to download netcat binaries for your platform. And here we go:

POST_PATH="/login.cgi"
HOST=199.188.1.99
BODY="Put here HTML body...."
BODY_LEN=$( echo -n "${BODY}" | wc -c )
echo -ne "POST ${POST_PATH} HTTP/1.0\r\nHost: ${HOST}\r\nContent-Type: application/x-www-form-urlencoded\r\nContent-Length: ${BODY_LEN}\r\n\r\n${BODY}" | \
  nc -i 3 ${HOST} 80

Based on Sending HTTP POST request with netcat post.
