shellcheck/build/README.md

This directory contains Dockerfiles for all builds.

A build image will:

• Run on Linux x86_64 with vanilla Docker (no exceptions)
• Not contain any software that would restrict easy modification or copying
• Take a cabal sdist style tar.gz of the ShellCheck directory on stdin
• Output a tar.gz of artifacts on stdout, in a directory named for the arch

This makes it simple to build any release without exotic hardware or software.

An image can be built and tagged using build_builder, and run on a source tarball using run_builder.

Tip: Are you developing an image that relies on QEmu usermode emulation? It's easy to accidentally depend on binfmt_misc on the host OS. Do a echo 0 | sudo tee /proc/sys/fs/binfmt_misc/status before testing.
