Install command
> sudo apt-get install pure-ftpd

Create group
> sudo groupadd ftpgroup

Create user
> sudo useradd -g ftpgroup -d /var/ftp/sillycat -s /bin/bash sillycat

Create Virtual User
> sudo pure-pw useradd sillycat -u sillycat -g ftpgroup -d /var/ftp/sillycat

first sillycat is virtual user
second sillycat is the system user, lock the user in the directory.

Create virtual user data
> sudo pure-pw mkdb

Soft link the user db to auth directory
> sudo ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/60puredb

Restart the server
> sudo /etc/init.d/pure-ftpd restart
Restarting ftp server: Running: /usr/sbin/pure-ftpd -l puredb:/etc/pure-ftpd/pureftpd.pdb -l pam -8 UTF-8 -u 1000 -J ALL:!aNULL:!SSLv3 -O clf:/var/log/pure-ftpd/transfer.log -E -B

Permission
> sudo chmod -R 777 /var/ftp

Verify the installation

> sudo apt-get install ftp

> ftp localhost 21

2 Set up PureFTPD in Docker on Ubuntu
Check docker version
> docker version
Client:
Version:      1.11.2
API version:  1.23
Go version:   go1.5.4
Git commit:   b9f10c9
Built:        Wed Jun  1 21:47:50 2016
OS/Arch:      linux/amd64

Server:
Version:      1.11.2
API version:  1.23

Git commit:   b9f10c9
Built:        Wed Jun  1 21:47:50 2016
OS/Arch:      linux/amd64

All similar to non docker, the docker file is as follow:
> cat Dockerfile
#Set up FTP in Docker

RUN apt-get -qq update

RUN pure-pw mkdb
RUN ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/60puredb

#start the application
EXPOSE  21
RUN     mkdir -p /app/
ADD     start.sh /app/

CMD [ "./start.sh" ]

docker run -d -p 21:21 -p 30000-30009:30000-30009 -v $(shell pwd)/ftp:/var/ftp --name $(NAME) $(IMAGE):$(TAG)

debug:
docker run -ti -p 21:21 -p 30000-30009:30000-30009 -v $(shell pwd)/ftp:/var/ftp --name $(NAME) $(IMAGE):$(TAG) /bin/bash

clean:
docker stop ${NAME}
docker rm ${NAME}

logs:
docker logs ${NAME}

publish:
docker push ${IMAGE}


> cat start.sh
#!/bin/sh -ex

#start the ftp
/etc/init.d/pure-ftpd restart
#tail the logging
tail -f /dev/null

Exception:
421 Unable to switch capabilities : Operation not permitted

Solution:
I am running that in one virtual ubuntu system. I will directly run that in my CentOS or RaspberryPi.
It works on CentOS.

3 PureFTP runs on RaspberryPi

All the configurations are the same for RaspberryPi

I was doing the things on and external USB hard driver through NTFS.
I get issues when I run the docker application
Error Message:
docker: Error response from daemon: error creating overlay mount to /mnt/driver1/data/docker/overlay/2a1f2702b7538a9ea5e070bd708e7f97c0df255fb76d73b48b2543f5c5fb40e1-init/merged: invalid argument.
See 'docker run --help'.
Makefile:12: recipe for target 'run' failed

Error Message:

Solution:
Do NOT use USB Driver to store docker images. Only configure the tmp directory to USB
> cat /etc/default/docker
# Docker Upstart and SysVinit configuration file

# This is also a handy place to tweak where Docker's temporary files go.
export TMPDIR="/opt/docker/tmp"

The Dockerfile need to be changed, it is not right to run things like that directly on raspberryPI arm system.

We need build the PureFTP ourselves with options.

That is done. It is running great there.

And when we are using FileZilla, make sure we are setting Transfer Settings to “Active”.
