On Docker's documentation page, there's an entry for docker builder which is the parent command of docker builder build. docker builder build seems like the exact same command as docker build, and the documentations provides no information about it. Are they literally the same thing?
Yes, currently they are behaving the same and builder is an alias. To understand why builder subcommand was presented, look at the commit message:
Add new
buildersubcommand and implementbuilder pruneto prune build cache.This patch adds a new builder subcommand, allowing to add more builder-related commands in the future. Unfortunately
buildexpects an argument so could not be used as a subcommand.This also implements
docker builder prune, which is needed to prune the builder cache manually without having to calldocker system prune.Today when relying on the legacy builder, users are able to prune dangling images (used as build cache) by running
docker image prune. This patch allows the same usecase with buildkit.
