Deployment on a Raspberry Pi

First, install the cross-compilation toolchain:

rustup target add armv7-unknown-linux-gnueabihf
sudo apt-get install gcc-arm-linux-gnueabihf

Now build the binary and prepare the deployment bundle:

make xcompile-arm
make prepare-deployment-bundle

Copy files to the Raspberry Pi:

scp -r './deployment-ef' pi@<rpi ip address>:

Finally, add the following lines to /etc/rc.local (sudo vim /etc/rc.local):

export ROCKET_ENV=production
cd /home/pi/deployment-ef && ./emoji-feedback en.toml &

Remotely accessing the log file

You have to generate an access token with python generate_auth.py (you will need Python >= 3.6). Add the auth.toml snippet to the configuration file and use the token in a GET request to /log_file/<token>, e.g. for the example config files use:

curl -X GET localhost:8000/log_file/9nmU49b8yqybNjUmkHDrPZNn

You can reset the log file by sending a DELETE request to /log_file/<token>. The log file will be moved to the location specified as backup_file in the config file.
