innosetup-idp-docker is a fork of the Docker Image amake/innosetup-docker. I wanted to fork this image to install and use Inno Download Plugin in addition to Inno Setup 6.
Because Inno Download Plugin has not a "silent install" option and amake/innosetup-docker is based on a X Server without display I inserted the needed files (idp.dll, idp.iss and default.iss) directly in the image.
Therefore it is possibile to use in the.iss file all the IDP directives; for more info see the directory examples in andykimpe/inno-download-plugin.
The Docker image is at https://hub.docker.com/r/adriespo/innosetup-idp.
Follow the same usage of https://github.com/amake/innosetup-docker/blob/latest/README.md.
