Olá.

Já desenvolvi aplicação usando docker-compose. Estou tentando desenvolver algo utilizando Nginx que próprio curso de Docker apresenta.

Entretanto quando executo docker-compose upele apresenta o erro

Starting nginx ...
Starting nginx ... done
Attaching to nginx
nginx    | 2018/03/13 02:17:02 [emerg] 1#1: "server" directive is not allowed here in /etc/nginx/nginx.conf:2
nginx    | nginx: [emerg] "server" directive is not allowed here in /etc/nginx/nginx.conf:2
nginx exited with code 1

Meu docker-compose.yaml meu yaml está 80% comentado para apenas testar levantar o servidor

E esse é o docker-file

FROM nginx:latest
LABEL Author="Gustavo Soares" 
COPY /client/public /var/www/public
COPY /docker/config/nginx.conf /etc/nginx/nginx.conf
RUN chmod 755 -R /var/www/public
EXPOSE 80
ENTRYPOINT [ "nginx" ]

CMD [ "-g", "daemon off;" ]

Caso tenham alguma outra dúvida, esse é meu git https://github.com/GustavoFSoares/hospital/. O projeto é público e qualquer um pode acessar.

De todo modo, obrigado pela força!
