How to Install Docker on Alibaba Cloud ?

To install Docker on Alibaba Cloud, you can follow the steps outlined below:

1. Create an Alibaba Cloud ECS Instance:

Log in to the Alibaba Cloud Console.
Navigate to the Elastic Compute Service (ECS) section.
Click on Create Instance to create a new ECS instance.
Select the desired instance type, region, and other configuration options according to your requirements.
Configure the network settings, storage, and security group for the
Complete the instance creation process by following the on-screen instructions.

2. Connect to the ECS Instance:

Once the ECS instance is created, you need to connect to it using SSH.
Retrieve the SSH key pair associated with the instance or create a new one during instance creation.
Use an SSH client (e.g., PuTTY for Windows or OpenSSH for Linux/macOS) to connect to the ECS instance's public IP address or domain name.

3. Update the System Packages:

After connecting to the ECS instance via SSH, update the system packages to ensure you have the latest versions:

sudo apt update
sudo apt upgrade

4. Install Docker:

Install the Docker dependencies by running the following command:

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Add the Docker GPG key to the system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add the Docker repository to the system's software sources:

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update the package index again:

sudo apt update

Install Docker:

sudo apt install docker-ce docker-ce-cli containerd.io

5. Verify the Docker Installation:

Check the Docker version to confirm the successful installation:

docker version

6. (Optional) Allowing Non-root Users to Use Docker (Recommended):

By default, Docker requires root or sudo privileges to run commands. To allow non-root users to use Docker, you can add them to the "docker" group:

sudo usermod -aG docker <username>

Replace with the actual username of the non-root user.

To apply the changes, either reboot the ECS instance or run the following command:

newgrp docker

That's it! You have successfully installed Docker on your Alibaba Cloud ECS instance. You can now use Docker to deploy and manage containers on your Alibaba Cloud infrastructure.
