This is a simple Docker container for jadx
The Dockerfile uses a minimalistic Arch Linux base image that installs jadx from blackarch's repo.
If you prefer to build the container yourself
$ git clone https://github.com/samsheff/docker-jadx
$ cd docker-jadx
$ docker build -t jadx .
If you trust me and prefer to download it directly from Docker Hub
$ docker pull samsheff/jadx
either way, then you can run it by executing
$ docker run -it samsheff/jadx
and passing it a volume argument
