Raspberry Pi 3 Installation Help

Hi there, I’d like to try and run this on my Raspberry Pi 3 running the lastest Raspian OS. I have docker installed and I ran the docker-compose build; I get to step 2 and then get this error:

Step 2/8 : RUN localedef -i de_DE -c -f UTF-8 -A /usr/share/locale/locale.alias de_DE.UTF-8
 ---> Running in 7d5ad4e57deb
standard_init_linux.go:211: exec user process caused "exec format error"
ERROR: Service 'db' failed to build : The command '/bin/sh -c localedef -i de_DE -c -f UTF-8 -A /usr/share/locale/locale.alias de_DE.UTF-8' returned a non-zero code: 1

I went into the db folder and commented out both lines similar to that command. The process then ran until:

2.4: Pulling from library/elasticsearch
ERROR: Service 'search' failed to build : no matching manifest for linux/arm/v7 in the manifest list entries

Is there any way I can continue, or will I have to install a flavour of Ubuntu to continue? If so, suggested flavours?
