I have trouble with using dockerfile to build image.
dockerfile:
FROM node:4.4
MAINTAINER paas
ENV NGINX_VERSION 1.11.6-1~jessie
RUN apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 \
&& echo "deb nginx.org/packages/mainline/debian/ jessie nginx" >> /etc/apt/sources.list \
&& apt-get update \
&& apt-get install --no-install-recommends --no-install-suggests -y \
ca-certificates \
nginx=${NGINX_VERSION} \
nginx-module-xslt \
nginx-module-geoip \
nginx-module-image-filter \
nginx-module-perl \

curl \
&& rm -rf /var/lib/apt/lists/*
RUN mkdir /etc/nginx/sites-enabled
# SSL Certificate Installation
ADD star_dar_kz.key /etc/ssl/
# ADD star_dar_kz.pem /etc/ssl/
# ADD dhparam.pem /etc/ssl/
# ADD nginx.conf /etc/nginx/
# ADD merchants.dar.kz.conf /etc/nginx/sites-enabled
COPY . /app
WORKDIR /app
RUN npm install --global gulp-cli
RUN npm install --global bower
RUN npm install
RUN bower --allow-root install
RUN gulp build --env prod
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
And after docker build, the GPG line appears as red and image creation fails. Why?
