portabledize

Bundle your app in a systemd portable service!

Installation

wget https://raw.githubusercontent.com/asiffer/portabledize/master/portabledize.sh

Get started

You need to provide two files:

The systemd service file (like my-service.service)
Extra files you want to map to the target image (you need to provide one binary at least)

Here is an example with a single binary to copy.

# files.txt
./my-binary /usr/bin/my-binary

Then you can run the script.

portabledize.sh -s my-service.service -f files.txt

It creates an image file my-service.raw in the current directory. You can modify the output directory with the -d option.

Important

It is important to keep this naming convention (if you provide wtf.service, it builds wtf.raw). Systemd won't accept image with filename different from service name.

Finally you can attach your service anywhere (where systemd runs!).

sudo portablectl attach ./my-service.raw
# sudo portablectl detach my-service

You can look at the ./example directory to see a true but basic sample.

Github Action

This repo follows the structure of a custom github action. So basically you can integrate portabledize to your CI/CD.
