Using nc (aka netcat) as a commonly available solution (but this syntax only tested for Alpine):

nc -lkp 8088 -e /bin/cat

nb:

• -l for listen
• -k to keep running for multiple calls (unavailable on busybox)
• -p for port parameter
• -e for program to execute (in the absence of a filename, cat echoes stdin to stdout)
