Dockermon Container / Image Build Details

The Dockermon container was tagged off of mysql/debian-8 container. From there it was tagged as webfreakeric/debian:0.1. After that, it was built with the following Dockerfile:

FROM webfreakeric/debian:0.2
WORKDIR /
RUN rm -rf /var/lib/apt/lists/* && \
rm -rf /etc/apt/sources.list.d/* && \
apt-get update && \
apt-get clean  && \
apt-get install -yq git curl gnupg iputils-ping vim procps redis tzdata socat && \
curl -sL https://deb.nodesource.com/setup_14.x | bash
RUN apt-get install -y nodejs && apt-get clean && rm -rf /var/lib/apt/lists/*
RUN rm -rf /etc/apt/sources.list.d/*

This installs Redis, Node 14, Git, socat and a few other basic utils to the system and then cleans the image of any temporary files.

From there, the image was exported and flattened into a new image to remove history / contexts (a problem with Docker is you can overload an image and it becomes massive). After that flattening, it’s built with the docker-compose.yml file and another build process which copies the dockermon-app code to the image and prepares it for distribution.

After that the image is packaged and pushed as webfreakeric/dockermon:latest and you can access it on Docker Hub.
