'geoip' failed to build: COPY failed

[tiofabby]

Hi,
I am trying to build freegeoip image from a docker-compose file but without success so far.
I am getting below issue indeed:

[root@vps....]# docker-compose up -d
Building geoip
Step 1/8 : FROM golang:1.9
 ---> ef89ef5c42a9
Step 2/8 : COPY cmd/freegeoip/public /var/www
ERROR: Service 'geoip' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder927407744/cmd/freegeoip/public: no such file or directory

This is what I have in my v3 docker-compose file:
Dockerfile of freegeoip being in /freegeoip folder

geoip:
   build: freegeoip
   network_mode: "host"
   environment:
   - FREEGEOIP_INTERNAL_SERVER=:8888
   - FREEGEOIP_HTTP=:9090
   logging:
     driver: "json-file"
     options:
       max-size: "5m"
       max-file: "2"

Am I doing something wrong?

Thank you
Fabrice
