Dockerfile RUN - file not found

Question

I'm trying to execute (RUN) a script but I'm getting a not file found error:

The line is: RUN settings/certs/install-certs.sh

The other lines that use files from the same path don't cause any issues.

What Am I missing here?

Dockerfile:

FROM container-registry.foo.net/maven:3.6.1-alpine as build
WORKDIR /app
COPY . .
RUN chmod +x settings/certs/install-certs.sh
RUN settings/certs/install-certs.sh
RUN mvn clean install -s settings/maven/docker-settings.xml

Output:

Answer 1

It turn out the line separator was the reason of the failure, replacing CRLF to LF did the trick.

Hard to identify when the error says "file not found".
