Overview of catching yaml issues for kubernetes

Automating the use of Linting Tools

With a custom YAML check

Many linters are external (shell) commands you can invoke with a filename, and which exit with non-zero status-codes on failure.

The problems a given linter will report upon will obviously vary, but actually executing a linter automatically is broadly tool-agnostic, so automating is pretty simple:

  • When you save a file, and it is of a type which has a linter associated with it:
  • Run the external linter command passing the filename as an argument.

Simple alternative to /usr/bin/lsb_release
#!/bin/sh
#
# This is a simple alternative to /usr/bin/lsb_release which
# doesn't require python.
#
# If /etc/os-release exists then we use that to output data
# in a compatible format to the original lsb_release utility.
#
# I consider this script trivial enough to be in the public-domain,
# but any patches or suggestsions will be welcome.

Linux Security Module - hashcheck - which checks that files have known-good hashes prior to command execution.
/*
* hashcheck_lsm.c - Steve Kemp
*
* This is a security module which is designed to prevent
* the execution of unknown or (maliciously) altered binaries.
*
* This is achieved by computing an SHA1 digest of every
* binary before it is executed, then comparing that to the
* (assumed) known-good value which is stored as an extended
* attribute alongside the binary.
