#Setting up Docker Machine on Raspberry PI

1. SSH into the pi and install docker with curl -sSL https://get.docker.com | sh (If we let Machine try to install the Docker daemon it will fail.)
2. Change the OS's ID so Docker Machine won't throw errors. sudo nano /etc/os-release and change the line that says ID=raspbian to ID=debian
3. From a new terminal window run docker-machine create --driver generic --generic-ip-address YOUR-PIS-IP --generic-ssh-key ~/.ssh/id_rsa --generic-ssh-user pi --engine-storage-driver overlay2 MACHINE-NAME

Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

• -r 24 - output frame rate
• -pattern_type glob -i '*.JPG' - all JPG files in the current directory
• -i DSC_%04d.JPG - e.g. DSC_0397.JPG
• -s hd1080 - 1920x1080 resolution
