In my dockerfile i'm trying to install binaries for Postgres, the thing is that the command:
RUN apt-get update \
&& apt-get -y install libpq-dev gcc
is trying to reach http://deb.debian.org/ over port 80.
Is there any way i can force this command to reference https://deb.debian.org/ over 443 instead of unencrypted http 80?

I'm trying to use Google Cloud Build to build my project which requires TexturePacker.
I managed to install TexturePacker but once script execute its CLI I get this error:
/usr/bin/../lib/texturepacker/TexturePacker_: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /usr/bin/../lib/texturepacker/TexturePacker_)
Tried to install necessary lib but still no success (like below):
FROM gcr.io/cloud-builders/yarn
RUN apt-get update && apt-get install -y libgl1-mesa-glx
RUN apt-get install -y libstdc++6
RUN wget https://www.codeandweb.com/download/texturepacker/5.2.0/TexturePacker-5.2.0-ubuntu64.deb && dpkg -i TexturePacker-5.2.0-ubuntu64.deb
Does anyone has an idea on how to fix it?
I was managed to solve it using this Dockerfile:
FROM node:latest
RUN apt-get update
# Install updates and dependencies
RUN apt-get install --no-install-recommends -y -q curl python build-essential git ca-certificates libkrb5-dev imagemagick && \
apt-get clean && rm /var/lib/apt/lists/*_*

Trying to build a simple ubuntu apache web server docker image, I get an error while the docker build command tries installing packages. I am using the Ubuntu base image in Docker to do this. Below is the code in my Dockerfile;
FROM ubuntu
RUN apt-get update
RUN apt-get install apache2
RUN apt-get install apache2-utils
RUN apt-get clean
EXPOSE 80
CMD ["apache2ctl", "-D", "FOREGROUND"]
My Host OS is Mac OSX El Capitan, and the error I get when the build fails is;
The command '/bin/sh -c apt-get install apache2' returned a non-zero code: 1
and my docker build command is;
docker build -t="webserver" .
Any help please. Thanks in Advance.
You should use the '-y' apt-get flag when building an image.
apt-get will ask you permission to continue with apache installation, and since you can't interact with the apt-get while building the image, you must pass the '-y' flag that means 'yes' to apt-get prompt.
Try changing it to:
FROM ubuntu
RUN apt-get update
RUN apt-get install apache2 -y
RUN apt-get install apache2-utils -y
RUN apt-get clean
EXPOSE 80
CMD ["apache2ctl", "-D", "FOREGROUND"]
or even:
FROM ubuntu
RUN apt-get update && apt-get install apache2 apache2-utils -y
RUN apt-get clean
EXPOSE 80
CMD ["apache2ctl", "-D", "FOREGROUND"]
I'm using docker to put together a script and its get stuck when this package xorg asks the prompt for the country of origin for the keyboard, I'll attach the image.
I've tried piping in the command like this from other answers I've read
RUN echo "29" | apt-get install -y xorg
But it didn't seem to work. I'm not sure how I get this to auto answer 29. Any help is appreciated.

There are quite a few issues I see with the Dockerfile provided.
Defining a volume inside the Dockerfile provides little to no value. It's much better to define this in your docker-compose.yml or as part of your run command. I've got a blog post going through the issues with this.
Splitting up the apt-get update from the later apt-get install commands can result in situations where the apt-get install will fail. There's a section in the best practices about this.
For your error message, I'd run apt-get in the noninteractive mode. You can also preconfigure debconf if you need a non-default value set during install.
Splitting each apt-get into a separate RUN command is creating lots of excessive layers, these should be merged where possible. This is also described in the best practices documentation.
Here's a sample of an install command that works for me taking the above into account:
FROM ubuntu:16.04
RUN apt-get update \
&& DEBIAN_FRONTEND=noninteractive apt-get install -y \
build-essential \
xorg \
libssl-dev \
libxrender-dev \
wget \
gdebi \
libxrender1 \
xfonts-utils \
xfonts-base \
xfonts-75dpi
Every time we reinstall nginx using passenger, we have to provide to it a bunch of options to define the paths, modules and options we'd like to activate, which can be a bit of pain.
Does anybody know of a way to automate this using some kind of answer file?
Yes you can use a provisioning tool like Chef or Puppet but in some cases those can be overkill. I just have a Bash script with some variables at the top that get changed as necessary, I then just transfer the script to the target server and execute it.
The actual packages for nginx & passenger I keep in my own S3 bucket.

passenger-install-apache2-module supports non-interactive, automatic, headless installs or upgrades through command line options. You can use those options to automate answers. This is documented in the manual: http://www.modrails.com/documentation/Users%20guide%20Nginx.html#_non_interactive_automatic_headless_installs_or_upgrades
Alternatively, you can install Phusion Passenger as if it's a normal Nginx module, and use the normal Nginx installation automation scripts: http://www.modrails.com/documentation/Users%20guide%20Nginx.html#_installing_as_a_normal_nginx_module_without_using_the_installer
You could use a provisioning tool such as chef or puppet. It may be overkill to use it for this case on its own, but you could use it to prepare entire servers or workstations from the ground up.
