Dockerfile for Laravel app to install libraries

Asked by Abzor

Hello,

The package spatie/laravel-pdf requires underlying Browshershot and Puppeteer. Missing libraries must be installed for this, like libnss3.

[2024-09-06 09:35:03] production. ERROR: The command "PATH=$PATH:/usr/local/bin:/opt/homebrew/bin NODE_PATH=`npm root -g' node '/workspace/vendor/spatie/browsershot/src/ .. /bin/browser.cjs' '{"url":"file:\/\/\/tmp\/1167844844-0405832001725615302\/index.html","action":"pdf","options": {"args": [" -- no-sandbox" ], "viewport": {"width": 800, "height":600},"displayHeaderFooter":false, "printBackground" : true}}'" failed.

Working directory: /workspace/public

Error: Failed to launch the browser process!
/workspace/.cache/puppeteer/chrome/linux-127.0.6533.88/chrome-linux64/chrome: error while loading shared libraries: libnss3
cannot open shared object file: No such file or directory

If I understand correctly, you have to create your own Dockerfile for this. I use App Platform so I didn’t have to do this, so I don’t know how to get this done.

Is there a Dockerfile example for a Laravel app?

Hello @abzor

You could use serversideup/php Docker images as a starting point for your project. In particular the 8.4-fpm-nginx tag which integrates nginx and fpm.

An example of a simple Dockerfile using this image and installing the libnss3 package could be the following:

FROM serversideup/php:8.4-fpm-nginx

# Switch to root so we can do root things
USER root

# Install nss3 library
RUN apt update && apt install -y libnss3

# Drop back to our unprivileged user
USER www-data

COPY --chown=www-data:www-data . /var/www/html
RUN composer install --optimize-autoloader --prefer-dist --no-dev --no-interaction

Let me know if this works for you.
