zipkin docker start error

docker-compose -f docker-compose.zipkin.yml up fails both for me and @ZolotarevIgor-mail-ru with

example client fails

Prerequirements:
tarantoolctl rocks install http 2.0.1
tarantoolctl rocks install tracing

Run:
tarantool formatter.lua,
tarantool publisher.lua in separate terminal window,
tarantool client.lua in separate terminal window.

Last one fails with

LuajitError: client.lua:85: Print string error: {"status":595,"reason":"Couldn't connect to server"}
fatal error, exiting the event loop

while tarantool formatter.lua still logs

started
entering the event loop
GET /format?helloto=world

tarantool publisher.lua logs only

entering the event loop

and there are some traces in Jagger:

Example uses deprecated HTTP v2

use HTTP v2 module, which is deprecated now (tarantool/http#142). HTTP v1 is installed by default from servers and, since v1 and v2 code is incompatible, example fails. It confuses users trying to run code from README (https://t.me/tarantoolru/182158).

how to install tarantool ?

intall tarantool in this way https://www.tarantool.io/en/download/os-installation/1.10/rhel-centos-6-7/ . but run tarantoolctl rocks install http 2.0.1 error, like this :

Installing http://rocks.tarantool.org/http-2.0.1-1.rockspec

Error: Could not find header file for TARANTOOL
No file tarantool/module.h in /usr/local/include
No file tarantool/module.h in /usr/include
You may have to install TARANTOOL in your system and/or pass TARANTOOL_DIR or TARANTOOL_INCDIR to the luarocks command.
Example: luarocks install http TARANTOOL_DIR=/usr/local
