+## pCloud Docker Container
+
+The Dockerfile downloads and builds the simple linux client for pCloud cloud storage into a tiny
+alpine Linux container. 
+
+### Build instruction
+
+```
+docker build -f Dockerfile -t pcloud .
+```
+
+Use 'docker images' to show the created container image:
+
+```
+core@m1 ~/pcloud $ docker images
+REPOSITORY                   TAG                 IMAGE ID            CREATED              SIZE
+pcloud                       latest              c1a2d69d3699        About a minute ago   19.02 MB
+```
+
+### Usage
+
+The container requires privileged mode in order to expose the Fuse based file system to the host.
+The default path of the mount point within the container is /root/pCloudDrive with supporting 
+files in /root/.pcloud (which contains e.g. the saved password). In order to gain persistency 
+between reboots and container restarts, the /root directory must be exposed and shared with the host.
+This is done via the docker run '-v' option combined with ':shared'. 
+
+Because the pcloudcc client doesn't offer a command line option to set the password or read from a file, the container must be launched once in interactive mode to set and save the password. 
+
+Launch the pcloud container with your pcloud username and options to set and save the password.
+Once the message 'status is READY' is shown, you can stop the container with Ctrl-C (to relaunch it later as a daemon).
+
+```
+/usr/bin/docker run --name pcloud -ti --rm --privileged -v /pCloud:/root:shared pcloud -u <username> -p -s
+pCloud console client v.2.0.1
+Please, enter password
+<enter-password-here>
+sh: lsb_release: not found
+Down: Everything Downloaded| Up: Everything Uploaded, status is LOGIN_REQUIRED
+logging in
+Down: Everything Downloaded| Up: Everything Uploaded, status is CONNECTING
+Down: Everything Downloaded| Up: Everything Uploaded, status is SCANNING
+event1073741824
+event1073741825
+Down: Everything Downloaded| Up: Everything Uploaded, status is READY
+^C
+```
+
+This initial run created the directory /pCloud on the host with the .pcloud pCloudDriver directories, though the latter is empty without a running container:
+
+```
+$ ls -la /pCloud/
+total 16
+drwxr-xr-x  4 root root 4096 Jan  2 13:53 .
+drwxr-xr-x 26 root root 4096 Jan  2 13:53 ..
+drwxr-xr-x  3 root root 4096 Jan  2 13:53 .pcloud
+drwxr-xr-x  2 root root 4096 Jan  2 13:53 pCloudDrive
+```
+
+Launch the container as daemon:
+
+```
+docker run --name pcloud -d --privileged -v /pCloud:/root:shared pcloud -u <username>
+```
+
+Verify the content of pCloudDrive:
+
+```
+$ ls /pCloud/pCloudDrive/
+Crypto Folder  My Pictures  Screenshots  pCloud Sync
+My Music       My Videos    Shared       pCloud Help  
+```
+
+### Systemd 
+
+Once an initial password has been set, the container can be managed automatically via systemd using the following service file:
+
+```
+$ cat /etc/systemd/system/pcloud.service
+[Unit]
+Description=pCloud
+After=docker.service
+Requires=docker.service
+
+[Service]
+TimeoutStartSec=0
+ExecStartPre=-/usr/bin/docker kill pcloud
+ExecStartPre=-/usr/bin/docker rm pcloud
+ExecStart=/usr/bin/docker run --name pcloud -i --rm --privileged -v /pCloud:/root:shared pcloud -u <username>
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and run the pcloud service with
+
+```
+sudo systemctl enable /etc/systemd/system/pcloud.service
+sudo systemctl start pcloud.service
+```
+
