[Docker] EISDIR: illegal operation on a directory, read

[ReganRyanNZ]

Detailed description

I am trying to run this line in gitlab ci:

docker run -v $(pwd)/crewmeister.yaml:/crewmeister.yaml wework/speccy lint /crewmeister.yaml

And it crashes with these logs:

$ docker run -v $(pwd)/crewmeister.yaml:/crewmeister.yaml wework/speccy lint /crewmeister.yaml
Could not open file: EISDIR: illegal operation on a directory, read
ERROR: Job failed: exit code 1

I have tried:

• Specifying a speccy version
• Mounting the volume under /project
• Using .yml instead of .yaml
• Using absolute paths instead of $(pwd)

And none of the above have changed the error.

Is there any way to fix this? Or even just get more information? What file is it trying to read?

I guess you are missing the /project part in the target, for me it works like this:

docker run -v $(PWD)/openapi.yml:/project/openapi.yml wework/speccy lint openapi.yml

Same error here.

The issue was: -v seems to expect an abolute path.

My solution to the "issue" is to have a bash wraper, so that I can call it with speccy MySpec.yaml

#!/bin/bash -e

dir="$( dirname "$1" )"
name="$( basename "$1" )"
cd "$dir"

docker run \
  -v "$PWD/$name":/project/"$name" \
  wework/speccy lint "$name"
