Otávio, boa noite !
Obrigado pela ajuda.
Estranho, eu iniciei, mas mesmo assim não esta funcionando.
Segue o código que estou utilizando para criar a imagem.
FROM node:latest
LABEL MAINTAINER="Thiago"
COPY . /var/www
WORKDIR /var/wwww
RUN npm install
ENTRYPOINT npm start
EXPOSE 3000
thiag@DESKTOP-QSEIU5Q MINGW64 /c/users/thiag/desktop/Docker/volume-exemplo $ docker build -f Dockerfile -t thiagomds/node . Sending build context to Docker daemon 6.656kB
