mkdir jessie-chroot
sudo debootstrap jessie ./jessie-chroot http://http.debian.net/debian/

Build docker image from tarball

cd jessie-chroot
sudo tar cpf - . | docker import - debian

Build new container

docker run -it --rm debian /bin/bash

docker run --name nifi -p 8080:8080 -d apache/nifi:latest

With interactive shell:

docker run -it apache/nifi bash

docker exec -it nifi bash

docker stop nifi

docker stop $(docker ps -aq) && docker rm $(docker ps -aq) && docker rmi $(docker images -aq) && docker volume rm $(docker volume ls -q)

(Docker aliases to set for the shell)

Restart rsyslog, the docker daemon and then all containers to switch to the new driver. Otherwise the docker daemon shows the following error message for the affected containers: “Configured log driver does not support reads, enabling local file cache for container logs”.
