Docker build

An originary Daedalus Project utility which allows users to create Docker images during CI/CD jobs.

This tool is curently used for creating all Docker images from Limani project. Images were only allowed to be uploaded to Docker Hub but other registry URL's can be used.

Installation

From source

Just follow these instructions:

git clone https://git.windmaker.net/a-castellano/DockerBuild.git && cd DockerBuild
make build
sudo make install

Using Repos

Add packages.windmaker.net repo:

apt-get install -y gnupg ca-certificates wget
wget -O - http://packages.windmaker.net/WINDMAKER-GPG-KEY.pub | sudo apt-key add - 
echo "deb [arch=amd64] http://packages.windmaker.net/ focal main" >> /etc/apt/sources.list 
apt-get update
apt-get install docker-build

Usage

This tool uses environment variables in order to obtain registry name, credential, image names, etc.

The following environment variables must be set in order to make this tool work:

DOCKER_REGISTRY_USER - specifies registry user.
DOCKER_REGISTRY_PASSWORD - specifies registry user password.
DOCKER_IMAGES_MAINTAINER - specifies Image maintainer name.
IMAGE_NAME - specifies the name of the image that this toll is creating.
IS_BASE_IMAGE - specifies is the image we want to create is a base image (see below)

Default registry is docker.io, when de default registry is being used the variable DOCKER_ORGANIZATION_NAME must be set, it can contain a user name instead of organizacion.

In order to use differente registry it mus be defined using variable DOCKER_REGISTRY_URL.

docker-build will look for a folder named as IMAGE_NAME value containing a valid Dockerfile.

export DOCKER_ORGANIZATION_NAME="acastellano"
export DOCKER_IMAGES_MAINTAINER="Álvaro Castellano Vela <alvaro.castellano.vela@gmail.com>"
export DOCKER_REGISTRY_USER="acastellano"
export DOCKER_REGISTRY_PASSWORD="my_dockerhub_password"
export IMAGE_NAME="test"
export IS_BASE_IMAGE=1

Base images

When [Limani](https://git.wind ddmaker.net/a-castellano/limani) CI/CD creates docker images during master deploy, all docker images must use the same tag, base images generate a timestamp, non base images read that timetamps and will use it in order to generate the same tag as base image.
