Installation of Docker software

To install Docker and configure the necessary repository on your system, execute the following commands with root or sudo privileges [ For Linux environment ] :

1. Install the yum-utils package

sudo dnf install -y yum-utils

2. Add the Docker repository

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

3. Install Docker Engine and related components

sudo dnf install -y docker-ce docker-ce-cli containerd.io

4. Enable the Docker service to start on boot

sudo systemctl enable docker

5. Start the Docker service

sudo systemctl start docker

6. Verify the Docker installation

docker –version

For Ubuntu based system use apt-get command.

Docker Installation on Ubuntu

Follow the steps below to install Docker Engine and related components on an Ubuntu-based system :

Update the Package Index.

1. Run the following command to ensure your package index is up to date :

sudo apt update

2. Install Required Packages for necessary certificates, tools, and libraries :

sudo apt install ca-certificates curl gnupg lsb-release -y

3. Add Docker's GPG Key and Create the keyrings directory and add Docker’s official GPG key :

sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

4. Set Up the Docker Repository and add Docker’s repository to your sources list :

echo \   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \   $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

5. Update the Package Index again and refresh the package index to include the Docker repository :

sudo apt update

6. Install Docker Components like Docker Engine, CLI, containerd, Buildx plugin, and Compose plugin :

sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

7. Verify Docker Installation

docker –version

These steps will ensure Docker is installed and operational on your Ubuntu system.

These steps ensure that Docker is properly installed and operational on your Linux as well as Ubuntu system, which is required for the Helyx replication setup.
