Docker uwegerdes/baseimage

A common base image for my Dockerfiles to save some disk space and build time.

The base for this image is ubuntu:latest but it might change in the future.

Install Docker

For Windows or Mac users: open https://www.docker.com/get-started in your browser.

Linux users: install Docker with:

curl -sSL https://get.docker.com | sh
sudo adduser [yourusername] docker

Building with settings

If you want to build it with other settings load the Dockerfile in an empty directory, perhaps edit it to your needs.

If you have an apt-cacher-ng proxy server (try uwegerdes/apt-cacher-ng) you should check hostname -i or change it to an address available in your local networt (not localhost) or omit the APT_PROXY line in the command above.

There is also a timezone parameter for the baseimage, here set to Europe/Berlin.

Build the image with (mind the dot in the last line):

$ docker build -t uwegerdes/baseimage \
	-t uwegerdes/baseimage:2022-08-21 \
	--build-arg APT_PROXY="http://$(hostname -i):3142" \
	--build-arg TZ="Europe/Berlin" \
	--build-arg TERM="${TERM}" \
	.

Usage

Use this baseimage in other Dockerfiles:

FROM uwegerdes/baseimage

Settings

The build-args are saved and used by all images depending on this image.
