docker build speed up with tmpfs
stop your docker service and create tmpfs disk on
/etc/fstab tmpfs /var/lib/docker/tmp tmpfs defaults,size=8G 0 0 tmpfs /var/lib/docker/containers tmpfs defaults,size=8G 0 0 tmpfs /var/lib/docker/aufs tmpfs defaults,size=8G 0 0 mount -a
start your docker service. This should speedup your docker build process significantly!
“docker build” takes usually a very long time, even if it is just a COPY or a RUN. Before the tmpfs change my docker builds did take about ~15 min, now its just 2-4 min! Keep in mind that you need a farly amount of ram in your Server/PC/Notebook for this to work eg min 16GiB in this setup!
