Unzipping of plugins fails.

[leon]

I have this strange problem with extracting my plugins.

I've got an image that is based on wordpress:4-fpm which should take all my checked in plugins and add them to the right dir.

FROM wordpress:4-fpm

# Install unzip
RUN apt-get update && apt-get install -y unzip

# Add all plugins from /plugins dir
WORKDIR /var/www/html/wp-content/plugins/

# Copy all plugins, zipped or not to /wp-content/plugins
COPY ./plugins/* ./

# Unzip
RUN unzip "*.zip"

# Permissions on everything
RUN chown -R www-data:www-data .

# Remove plugins
RUN find . -name '*.zip' -delete

The strange thing is that it doesn't work.
If I change from FROM wordpress:4-fpm to FROM debian:jessie it works as expected.

I've done a small repo demonstrating the strange behavior.

Does anyone have a clue as to why this isn't working?
Has it got anything to do with how wordpress copies itself to /var/www/html/?

The problem is that /var/www/html is a volume. I'd recommend expanding your plugins into /usr/src/wordpress/wp-content/plugins to take advantage of the copying step in the entrypoint that you mentioned.

Thanks!
now it's working as expected.
