Miscellaneous hooks for pre-commit.

• check-zero-width-spaces - Forbid files which have one or more zero width spaces (U+200B).

• hadolint - Run Hadolint on Dockerfiles.

  • You may use any Hadolint CLI argument, e.g. --config example.yaml, --ignore RULE, --trusted-registry REGISTRY, etc. See the example below.

• nomad-fmt - Run nomad fmt on Nomad manifests.

• packer-validate - Run packer validate on JSON files.

1. Install dependencies:

   • pre-commit
   • Hadolint (for hadolint)
   • Packer (for packer-validate)

2. Install the pre-commit hook globally:

   $ pre-commit init-templatedir -t pre-commit ~/.git-template

3. Create the .pre-commit-config.yaml file:

   $ cd /path/to/my/repo/
   $ vim .pre-commit-config.yaml

   Tip: use the example from the next section as a start point.

4. Run:

   $ pre-commit run -a

# .pre-commit-config.yaml
