Puppeteer docker

It can also be configured to use full non-headless Chrome or Chromium. Most things that you can do manually in the browser can be done using Puppeteer! Here are a few examples to get you started:.

I'm trying to launch puppeteer in an express app that's run in a docker container, using docker-compose.

What is the expected result? Puppeteer can launch a browser in the express app. Run "npm install". I've tried adding a yarn add puppeteer after the yarn install in the Dockerfile. I've also tried replacing yarn install in the Dockerfile with npm install. Neither makes a difference. Assuming your package. Can you docker exec into the container and verify if there's a populated. There is:. That path looks like it's from a mac. If you're in Docker, it should be something like. That's it.

The last line in volumes in the docker-compose. Did you find a solution for this I am experiencing the same issue, what did you have to change in your docker-compose. I am on a windows machine, any ideas how I can fix the issue? But still need a solution to fix it without the manual hassle. If you are connecting to an instance of puppeteer in a linked container, you should use puppeteer.

My quick fix was to manually run install. I don't know where I found this solution it was another GitHub issue. I am running node 12 alpine inside a docker container, and these 3 lines were necessary right before RUN npm install.Not all the features of Chrome, however, are available when running in this mode.

If you want to write a scraper it quickly becomes very annoying to add all these extra steps to your puppeteer scripts.

Running Puppeteer-Sharp on Docker

The same goes for all the adverts you might one to block and not handle individually. There are all kinds of extensions available that can help you with this. The goal is to use an extension to bypass GPDR cookie consent popups.

This script will pull in a web page and show the complete content. But first the project setup…. Start with creating a directory and add the following package. This contains a minimal configuration for our project.

Create a src directory in the new project and in that directory create a file called scrape. We compile the typescript to javascript and run the result. This will pop up a chrome browser window, load the site, wait for loading to be finished, and finally get the page content and dump that to the console. We can run this like so:. But like we mentioned before. Before we can use an extension we need to download it and add it to where our puppeteer instance can find it.

For this we use crxextractorwhich allows us to download an extension. Use this site to download the extension:. Save the downloaded crx file somewhere which is just a zip fileand extract it like this in your project directory:. Now we can configure puppeteer to use these extenstions.

For this we just need to replace the arguments like this:. This will load the extension from the provided path. We need to specify both the --disable-extensions-except and the --load-extension with the path for the extension to be picked up correctly. Note that now headless needs to be set to false. The final property we need to set is --no-sandboxsince else chromium refuses to load the extensions. If puppeteer starts without complaining it usually means the extensions are correctly defined, and as you can see in the previous image, the consent popup we saw is now missing.

Just what we were aiming for. The next step is running this same configuration from a docker file. That way we can just run this script inside a docker container, and have the docker environment provide the windowing system. Quickly summarized xfvb provides this:. Xvfb is an X server that can run on machines with no display hardware and no physical input devices. It emulates a dumb framebuffer using virtual memory.

Product integrations

We could of course also add the tsc and for a real project all the other steps in this, or use a multi-stage docker build. For this example though, just make sure to run tsc before building the docker image.

And with that container build, we can now simply run the container, which will run our script, fire up a full-fledged chromium browser, with our extensions enabled, and output the HTML.

This provides a simple way of running Puppeteer combined with any extension you want, without having to deal with browser windows showing everywhere.Should I use Puppet to deploy Docker on my nodes, and then use Puppet to define container images? Or should I use Docker containers to deploy Puppet so I can test dashboards and other modules without having to build out my infrastructure? In reality, you can do both.

Modern Web Testing and Automation with Puppeteer (Google I/O ’19)

A few handy repositories in the Puppet Forge and GitHub will help get you started. The fact that these modules have been downloaded nearly two million times from the Puppet Forge gives you an idea of their utility. Once deployed to a node, Docker will run and behave just as it would if you installed it manually.

Using Puppet to automate this basic step, though, is a great way to deploy as many instances you want, the same way every time. With Docker installed, you can start running some simple tests, like pulling down the latest version of the Centos image:. For example:.

This is a good way to experiment with and learn Puppet with very little infrastructure or overhead. Instead of building out a full virtual machine and setting it up as a Puppet node, you can use a straightforward Docker command to see how Puppet would make a change or apply some action. If something breaks, you can just remove the containers and start over. You can actually move well beyond launching a handful of containers, and run your Puppet infrastructure on top of a containers-as-a-service platform.

In this example, the Puppet master is created in a container called puppet on a Docker network named "puppet. All the open-source components of a stand-alone Puppet infrastructure are available in this same fashion, including Puppet Server, PuppetDB and various dashboards. You can put them all back together as a stack with Docker Compose.

Compose is a YAML file format that enables you to describe a series of containers in key-value pairs, and define how they should be related and linked. You can manually install docker-compose or install it using the docker::compose class in the docker module mentioned above. To test the power of Docker Compose, create a docker-compose. The file describes several container images, including puppetserver, puppetdb-postgres, puppetboard and puppetexplorer.

These last two are browser-based dashboard components that will become accessible when Docker Compose completes. You can can see all the bits and pieces and see how it works in moments, instead of setting up a series of VMs. Figure 2. The Caddy dashboard for Puppet Explorer, running in a container installed using docker-compose.

At the same time, docker-compose installed PuppetDB and the browser-based dashboard that makes monitoring database activity a snap:. You should now begin to see how the combination of Puppet and Docker gives you new and powerful ways to expand your development environment.

Instead of deploying one Puppet node at a time, you can use simple Docker commands to do the work for you. That means you can spend less time building the platform, and more time developing and testing.

And because these environments are up and running in minutes, you can deploy as many as you want almost anywhere you want — and easily start over with a clean install every time. Build a Puppet environment with a single command You can actually move well beyond launching a handful of containers, and run your Puppet infrastructure on top of a containers-as-a-service platform.

Figure 1. Several Puppet nodes are deployed as containers using docker-compose. Figure 3. The PuppetDB dashboard, running in a container created by docker-compose. Conclusion You should now begin to see how the combination of Puppet and Docker gives you new and powerful ways to expand your development environment.

That would leave our user setup like this:. This is important because BrowserFetcher is not going to download a valid version to be used on Docker.

So, how do we tell Puppeteer-Sharp to use that Chrome?

Running Puppet software in Docker containers

Easy, we can set an environment variable:. We are not going talk about the --no-sandbox on this post. You will find many posts on the internet about the goods and bads of this flag. You can also take a look at the official doc. If you are ok adding the --no-sandbox flag on your app, because you will browse a website you own or trust, you can remove all the user setup.

But if you try to launch Chrome you might get this error:. You will find manymany posts talking about this. I found the solution on this post. After doing all that setup, we need to do a normal.

NET deploy to that Docker. You can copy the source code and make the publish inside the image or copy an existing publish there, just like this:. Does it work? I hope this post helps the community to start using Puppeteer-Sharp on Docker. I will see if I can publish these images to the Docker Repository, stay tuned!

I get many questions about running Puppeteer-Sharp on Docker. FROM nodeslim Install latest chrome dev package and fonts to support major charsets Chinese, Japanese, Arabic, Hebrew, Thai and a few others Note: this installs the necessary libs to make the bundled version of Chromium that Puppeteer installs, work.

If you do, you'll need to launch puppeteer with: browser. FROM nodeslim. FROM mcr. Install latest chrome dev package and fonts to support major charsets Chinese, Japanese, Arabic, Hebrew, Thai, and a few others Note: this installs the necessary libs to make the bundled version of Chromium that Puppeteer installs, work.It can be used to control Headless Chrome over the DevTools protocol.

You can use it for crawling, scraping, automation, generating PDFs, automated testing and much much more. This may lead to a bit of fumbling around, especially if you are on a less-well-supported OS and have to find out the names of all packages by yourself, just to discover that you need to apply all kinds of fixes to make it work properly.

Puppeteer – Headless Chrome in a Container

Docker makes it possible. The following is the result of creating a very quick prototyping environment.

You can find the final code in this GitHub repository. After cloning the GitHub repositoryissue a. The image is based on the official Node image, and contains additional libraries and tools which are needed by Puppeteer and Headless Chrome. What glues everything together, and configures the containers is the docker-compose.

The Node dependencies, reside in the code folder as well, and are ignored by Git. This means, that restarting containers does not require reinstalling everything from scratch, keeping the startup time low and iteration cycles as quick as possible.

Right now, docker-compose. We might add a database or message queue - any supporting services which our code needs. The current Node code, does not require many additional packages or libraries. You can install anything you like, to create a really cool project. If you need system libraries or tools, simply add them to the Dockerfile and execute a.

Of course, the current setup is not meant for anything but development environments. This post introduced my take on a quick dockerized Puppeteer development environmentto work with the Headless Chrome Node API locally. Clone the project and try Headless Chrome and Puppeteer yourself! As stated above, this is my take on a quick dockerized version, which is meant solely for development.

Headless Chrome is started disregarding possible security issues, and your code will run as root within the container. Use it with caution!
