Loop to echo out container stats to a file

This was helpful to get an initial impression of the resource requirements of a couple of running containers before migration to a new infrastructure environment.

for i in {1..2880}; do
    echo "------ $(date) ------" >> docker_stats_CONTAINER_NAME.txt;
    docker stats $(docker ps --format '{{.Names}}' | grep 'CONTAINER_NAME') --no-stream >> docker_stats_CONTAINER_NAME.txt;
    sleep 300;
done
