Itema e-mail signature generator
The following code will build and create an Docker image file that can be started as a container.
./mvnw install dockerfile:build && rm -f itema-isig.tar.gz \
&& docker save no.itema/isig | gzip -c > itema-isig.tar.gz
The image file will weigh in at about 134MiB.
If Java is not installed on your system, the iSig service can run using Docker only. See the README in the docker folder
