Shell Dep Download File

Let’s build one step by step. Assume we want to download kubectl version 1.28.0.

For developers, combining make with shell download creates reproducible builds.

Example Makefile:

DEP_URL = https://github.com/example/cli/releases/download/v2.0/cli_linux_amd64
CHECKSUM = a3b4c5d6...
bin/cli:
mkdir -p bin
curl -L -o bin/cli $(DEP_URL)
echo "$(CHECKSUM) bin/cli" | sha256sum -c -
chmod +x bin/cli
clean:
rm -rf bin
.PHONY: clean

Run make and the shell dep download happens automatically.
