Modifying an Existing Docker Image

To install a custom package or modify an existing docker image we need to

run a docker a container from the image we wish to modify
modify the docker container
commit the changes to the container as a docker image
test changes made to image

1.) Running a docker container from an image

Lee Benfield's Java decompiler CFR is straight forward and can even batch decompile jar container.

Download the most recent version of CFR (crf 0.1.15 at the time of writing)

cd /usr/local/bin && wget http://www.benf.org/other/cfr/cfr_0_115.jar

Run decompile with output into terminal

java -jar /usr/local/bin/cfr_0_115.jar javaclasstodecompiles.class

Diagrams

Markdown Preview Enhanced supports rendering flow charts, sequence diagrams, mermaid, PlantUML, WaveDrom, GraphViz, Vega & Vega-lite, Ditaa diagrams. You can also render TikZ, Python Matplotlib, Plotly and all sorts of other graphs and diagrams by using Code Chunk.

Please note that some diagrams don't work well with file exports such as PDF, pandoc, etc.

Flow Charts

This feature is powered by flowchart.js.
