install chromedriver in docker container

In this article, we are going to learn how we can run our simple Selenium WebDriver Test cases on Docker. There are many docker terms but the most imp is images and containers, you can have a look for all the terms in Docker glossary. They all look same from the outside but can look very different from the inside. Another comparison would be too real containers on the ship.

Compare it to object-oriented programming, then your class would be an image and instance of the class a container. Images are stored in a Docker registry such as #Containers:Ĭontainers are the instantiations or runtime instance of images.

Images are created with the build command, and they’ll produce a container when started with the run. Docker Terminology #Images:Īn Image is an inert, immutable, file that’s essentially a snapshot of a container.An image typically contains a union of layered filesystems stacked on top of each other. Companies use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server. You should find Puppeteer executes successfully, provided proper Chrome flags are used.Docker containers allow you to package up an application with all the basic parts to run, such as libraries and other dependencies, and ship it out as one package.ĭevelopers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Chrome will write into /tmp instead.Īdd your JavaScript to your container with a COPY instruction. disable-dev-shm-usage – This flag is necessary to avoid running into issues with Docker’s default low shared memory space of 64MB.If you’re uncomfortable with this, you’ll need to manually configure working Chrome sandboxing, which is a more involved process. It’s vital you ensure your Docker containers are strongly isolated from your host. Using these flags could allow malicious web content to escape the browser process and compromise the host. no-sandbox and disable-setuid-sandbox – These disable Chrome’s sandboxing, a step which is required when running as the root user (the default in a Docker container).Setting this flag explicitly instructs Chrome not to try and use GPU-based rendering. disable-gpu – The GPU isn’t usually available inside a Docker container, unless you’ve specially configured the host.
