GUI on the Docker 🐋

✨ What is Docker ?

Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines.

Task Description 📄

📌 GUI container on the Docker

🔅 Launch a container on docker in GUI mode

🔅 Run any GUI software on the container

Let’s Begin🤩

Step1 : Install docker

A ] Configure yum for Docker :

Create a file “/etc/yum.repos.d/docker.repo”[docker]name=docker repo baseurl=https://download.docker.com/linux/centos/7/x86_64/stable/
gpgcheck=0

After this verify by “yum repolist” . You see some more software.

B] Install Docker and start service :

# Install docker
yum install docker-ce — nobest # Start Docker service
systemctl start docker# Enable Docker service
systemctl enable docker

Step2 : Pull centos image

docker pull centos:latest

Step3 : Launch a container

docker run -it — name <os_name> — net=host — env=”DISPLAY” — volume=”$HOME/.Xauthority:/root/.Xauthority:rw” <image>:<version>

• We have to provide this as a option to share docker host i.e in our case RHEL8 XServer.

# share the Host’s XServer with the container by creating a volume
--volume="$HOME/.Xauthority:/root/.Xauthority:rw"

# to share the host display environment to the container.
--env="DISPLAY"

# to run container with host network
--net=host

Now, run the container by providing these option.

Step3: Install required packages in container

# python # firefox
yum install python36 firefox -y

# installing required libraries for task
pip3 install jupyter

✨Let’s launch jupyter notebook inside container :
