Currently such syntax is supporting by hadolint for Inline ignores:

# hadolint ignore=DL3003,SC1035

When I use Shellcheck, I prefer expanding a comment with text description, which is more human-readable:

# shellcheck disable=SC1091  # File not included in mock

Can we have similar logic for hadolint: to ignore whitespaces and custom text (for example, starting with #) in the same line after ignore=ID1,ID2?

Expected behavior

Line

# hadolint ignore=SC1091  # File not included in mock

makes hadolint ignore SC1091 in the next line.

Actual behavior

Code

# hadolint ignore=SC1091  # File not included in mock
RUN python3 -m venv .venv && . .venv/bin/activate && pip3 install --no-cache-dir -r requirements.txt

gives a message like: "Dockerfile:7 SC1091 info: Not following: File not included in mock."

Steps to reproduce the behavior

Create a Dockerfile like

FROM python:3

RUN groupadd -r myapp && useradd --no-log-init --system --gid myapp --create-home myapp
USER myapp

# hadolint ignore=SC1091  # File not included in mock
RUN python3 -m venv .venv && . .venv/bin/activate && pip3 install --no-cache-dir -r poetry

Check it with hadolint, it will give you a message: "Dockerfile:7 SC1091 info: Not following: File not included in mock."

Output of hadolint --version:

Haskell Dockerfile Linter 2.12.0

Dockerfile (if relevant)

# hadolint ignore=SC1091  # File not included in mock
RUN python3 -m venv .venv && . .venv/bin/activate && pip3 install --no-cache-dir -r requirements.txt

Additional environment details (OS, stack version, etc.)

Probably my request may also close #997.
