Running Chrome in Docker container

Summer - Task 02 👨🏻‍💻

By default containers don't support GUI, but by some way we can achieve that, let's discuss

Lets start docker

Now lets launch a container (with centos:7 image)

Chrome-Installation

Go to /etc/yum.repos.d and make a file google-chrome.repo and put this ->

[google-chrome]
name=google-chrome
baseurl=http://dl.google.com/linux/chrome/rpm/stable/$basearch
enabled=1
gpgcheck=1
gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

install by

yum install google-chrome-stable

Now update the installation

Now let's try to run chrome

We see the error here because we didn't mention the display variable.

The DISPLAY variable is used by X11 to identify your display. While launching this container I did not specify any DISPLAY Variable. Without the display variable we can't run GUI apps inside a container.

Now let's launch a new container with DISPLAY variable

After configuring yum repo and installing chrome as same we did for first container, now launch chrome in this container

google-chrome --no-sandbox

Now chrome runs inside the container, as we had mentioned DISPLAY variable while launching this container!
