You should also set up Chrome Launch arguments so that the browser works properly in your documented environment. Your container needs to have the right dependencies installed.

It also helps you isolate your environment during development, so you donвЂ™t need to install Chrome locally. Running a puppet in a docker container allows you to automate your websites as part of your CI pipelines and production infrastructure. COPY Instructions You must execute the puppet successfully, provided appropriate chrome flags are used. tmp InsteadДЄdd your javascript to your container with a. disable-dev-shm-usage вЂ“ This flag must ensure that DockerвЂ™s default low shared memory space of 64MB is not compromised.If you are worried about this, you will need to manually configure working chrome sandboxing, which is a more involved process. It is important that you make sure that your docker containers are firmly isolated from your host. The use of these flags allows bad web content to evade the browser process and compromise with the host. no-sandbox And disable-setuid-sandbox вЂ“ Disables ChromeвЂ™s sandboxing, a step that is required when root User (default in docker container).Configuring this flag explicitly instructs Chrome not to attempt GPU-based rendering. disable-gpu вЂ“ The GPU is usually not available inside the docker container, unless you have specifically configured the host.The main section is a list of arguments that have been moved as part of Chromium. The browser then shuts down so that system resources are not wasted. It demonstrates a simple script that starts a head Chrome instance, goes to the URL, and gets a screenshot of the page. One minimal example of using puppets inside your container is:Д¬onst puppeteer = require ( 'puppeteer' ) const browser = await puppeteer. Despite installing all the dependencies, the environment still looks different from most regular Chrome installations, so additional launch flags are needed. When you are using Puppet in a docked environment, there are some special ideas for launching Chrome. This is a large construction process that can take several minutes on a slow internet connection. This helps reduce your last image.ДЄt this point you should be ready to create your image: docker build.

To arrange PUPPETEER_SKIP_CHROMIUM_DOWNLOAD Environmental variables before running npm ci Puppeteer will disable your browser download during installation. You may want to manually install a specific version of Chrome in a custom environment. RUN chmod -R o+rwx node_modules/puppeteer/.local-chromium Otherwise, whenever you try to start Puppet Chrome, you may encounter permissions errors. The final step is to make the puppet bundle chromium binary work properly. In your docker file, copy and use these files in the container. package.json And package-lock.json For your use. npm install puppeteer In your local working directory. This ensures consistency between puppet releases and avoids the possibility of new chrome releases that arrive with puppet-breaking inconsistencies. Reliance is being installed manually to facilitate the use of Chromium Binary, which is bundled with Puppet. All this needs to be installed in your docker file.ДЄt the time of writing, the current dependency list looks like this: FROM node:latest npm install puppeteer Will force you to run In practice, a clean docker environment will lack the dependence that you need to run Chrome.ДЄs it is usually a heavyweight GUI program, it depends on the Chrome font, graphics, configuration, and window management libraries. It bundles the latest chromium builds inside its package, so theoretically one. Puppet is distributed through Npm, Node.js Package Manager.
