# How to install Docker
|
||
|
|
|
||
|
|
This guide provides step-by-step instructions for installing Docker Community Edition (CE) on Ubuntu, specifically tested on version 22.04. Docker is a powerful tool for containerization, allowing you to separate different services into individual containers and offering better resource efficiency compared to virtual machines.
|
||
|
|
|
||
|
|
* Begin by updating your apt repository to ensure you have the latest package information and dependencies. Open a terminal and run the following command:
|
||
|
|
```
|
||
|
|
apt update
|
||
|
|
```
|
||
|
|
This command will refresh the package lists and update any outdated packages on your system.
|
||
|
|
|
||
|
|
* Next, you need to ensure that the curl utility is installed. This tool is used to transfer data to or from a server using various protocols. If you already have curl installed, you can skip this step. Otherwise, execute the following command in the terminal to install it:
|
||
|
|
```
|
||
|
|
apt install curl
|
||
|
|
```
|
||
|
|
This command will download and install curl from the Ubuntu repositories.
|
||
|
|
|
||
|
|
* Now, you can proceed with the installation of Docker. Docker provides a convenient installation script that you can run to automatically set up the necessary components. Execute the following command in the terminal:
|
||
|
|
```
|
||
|
|
curl -sSL https://get.docker.com/ | CHANNEL=stable bash
|
||
|
|
```
|
||
|
|
This command downloads the Docker installation script and pipes it to the bash shell, which executes the script. The CHANNEL=stable option ensures that the stable version of Docker is installed.
|
||
|
|
|
||
|
|
* Once the installation process is complete, you can verify that Docker is working correctly. Run the following command in the terminal:
|
||
|
|
```
|
||
|
|
docker --version
|
||
|
|
```
|
||
|
|
|
||
|
|
This command displays the version of Docker installed on your system. You should see an output similar to the following:
|
||
|
|
```
|
||
|
|
➜ ~ docker --version
|
||
|
|
Docker version 23.0.6, build ef23cbc
|
||
|
|
```
|
||
|
|
|
||
|
|
Congratulations! You have now installed Docker Community Edition on your Ubuntu machine. Docker is ready to be used, allowing you to leverage the power of containerization for your projects and applications.
