Client example

This a client that simulates a gRPC consumer. We're using this for the time being to document the interaction with the gRPC interface.

To use it run arduino-cli daemon and then client_example.

To test the proxy settings first run:

docker run --name squid -d --restart=always \
  --publish 3128:3128 \
  --volume /path/to/squid.conf:/etc/squid/squid.conf \
  --volume /srv/docker/squid/cache:/var/spool/squid \
  sameersbn/squid:3.5.27-2

The squid.conf file to use is in this directory so change the volume path to that.

To verify that requests are passing through the local proxy run:

docker exec -it squid tail -f /var/log/squid/access.log

If it works you should see logs similar to this:
