/usr/local/bin/docker-entrypoint.sh can not splice command and parameters correctly

[stanxing]

Environment

• Platform: Macos & CentOS
• Docker Version: 19.03
• Node.js Version:
• Image Tag: node:14-slim

Expected Behavior

docker run -it --rm \
    --name "test-slim" \
    --workdir /app \
    -v $(pwd)/:/app \
    node:14-slim \
    dist/index.js

docker run can run correctly.

Current Behavior

The docker command has saome errors as below:

/usr/local/bin/docker-entrypoint.sh: 11: exec: dist/index.js: Permission denied

I debug found that [ -z "$(command -v "${1}")" ] return wrong bool value causing executable command could not patch node prefix. I executed this script in my local env without docker and it worked. My sh version is 3.2, maybe is sh version the root casue in image?

This is docker-entrypoint.sh, https://github.com/nodejs/docker-node/blob/main/docker-entrypoint.sh#L4

#!/bin/sh
set -e

if [ "${1#-}" != "${1}" ] || [ -z "$(command -v "${1}")" ]; then
  set -- node "$@"
fi

exec "$@"
