Request error when running demo hello example in README #695
Description
Hi, I am trying to run the end-to-end quick start examples from README, but I am unable to do so because of the request error with inv.
for res in socket.getaddrinfo(host, port, family, socket.SOCK_STREAM):
File "/usr/lib/python3.8/socket.py", line 918, in getaddrinfo
for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -3] Temporary failure in name resolution
....
urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPConnection object at 0x7f2816a49040>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution
.....
requests.exceptions.ConnectionError: HTTPConnectionPool(host='worker', port=8080): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f2816a49040>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))
Is there any procedure that I missed?
Here are a few things that I tried:
- running
docker compose up -d --scale worker=2 nginx
docker compose run cpp /bin/bash
from README will run two separate clusters. I fixed it by running them together and modify the cpp docker compose to use local host network.
- however, when I ran to the step
inv func.upload demo hello
it shows the request error shown above.
I used
/code/cpp# curl -X PUT localhost:8002/f/demo/hello -T /code/cpp/build/func/demo/hello.wasm
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

curl: (52) Empty reply from server
to bypass the error.
- Then the
invinvoke also causes the same error message of name resolution. I am unable to bypass the error by writing the python script from https://faasm.readthedocs.io/en/latest/source/api.html.
/code/cpp# python3 request.py
