Bitcoind docker image not supported on ARM devices
Created by: Technifocal
x86_64-linux
build of Bitcoind is pulled here
Replacing it with https://bitcoincore.org/bin/bitcoin-core-0.18.0/bitcoin-0.18.0-arm-linux-gnueabihf.tar.gz
(and commenting out the SHA256 check) works fine (though then that'd obviously break x86_64 support). This needs to be determined at build time.
