sudo<\/code> privileges<\/li>\n<\/ul>\n\n\n\nDocker supports multiple architectures, including x86_64<\/code>, armhf<\/code>, arm64<\/code>, s390x<\/code>, and ppc64le<\/code>.\n\n\n\nStep 1: Update Your System<\/h2>\n\n\n\n Before installing any new software, it’s a good practice to update your system’s package list. Open a terminal and run the following command:\n\n\n\n
\n
sudo apt-get update<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis command updates the list of available packages and their versions.\n\n\n\n
Step 2: Install Required Packages<\/h2>\n\n\n\n To set up Docker on your system, you need to install a few prerequisite packages. These packages help in adding the Docker repository and managing the keys securely:\n\n\n\n
\n
sudo apt-get install ca-certificates curl gnupg<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis command installs ca-certificates<\/code>, curl<\/code>, and gnupg<\/code>, which are required for Docker installation.\n\n\n\nStep 3: Add Docker\u2019s Official GPG Key<\/h2>\n\n\n\n Next, you need to add Docker\u2019s official GPG key to your system. This key ensures that the software you\u2019re about to install is authentic and hasn\u2019t been tampered with:\n\n\n\n
\n
sudo install -m 0755 -d \/etc\/apt\/keyrings\ncurl -fsSL https:\/\/download.docker.com\/linux\/ubuntu\/gpg | sudo gpg --dearmor -o \/etc\/apt\/keyrings\/docker.gpg\nsudo chmod a+r \/etc\/apt\/keyrings\/docker.gpg<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis will download the GPG key and place it in the appropriate directory on your system.\n\n\n\n
Step 4: Set Up Docker Repository<\/h2>\n\n\n\n With the GPG key added, you can now add the Docker repository to your system\u2019s list of repositories:\n\n\n\n
\n
echo \\\n "deb [arch=$(dpkg --print-architecture) signed-by=\/etc\/apt\/keyrings\/docker.gpg] https:\/\/download.docker.com\/linux\/ubuntu \\\n $(. \/etc\/os-release && echo "$VERSION_CODENAME") stable" | \\\n sudo tee \/etc\/apt\/sources.list.d\/docker.list > \/dev\/null<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis command sets up the repository from which Docker can be installed and updated.\n\n\n\n
Step 5: Install Docker Engine<\/h2>\n\n\n\n With the repository set up, you can now install Docker Engine and its associated components:\n\n\n\n
\n
sudo apt-get update\nsudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis installs the latest version of Docker, including the Docker Engine, Docker CLI, and additional plugins.\n\n\n\n
Step 6: Verify Docker Installation<\/h2>\n\n\n\n After the installation is complete, you can verify that Docker was installed correctly by running the hello-world<\/code> image:\n\n\n\n\n
sudo docker run hello-world<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nIf everything is working properly, you should see a message that says “Hello from Docker!” This confirms that Docker is installed and running.\n\n\n\n
Step 7: Post-Installation Steps (Optional)<\/h2>\n\n\n\n7.1 Run Docker Commands Without Sudo<\/h3>\n\n\n\n By default, Docker commands require sudo<\/code> privileges. If you want to allow your user to run Docker commands without sudo<\/code>, follow these steps:\n\n\n\n\n
sudo groupadd docker\nsudo usermod -aG docker $USER\nnewgrp docker\n#restart your pc<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nAfter running these commands, log out and log back in to apply the changes.\n\n\n\n
7.2 Enable Docker to Start on Boot<\/h3>\n\n\n\n To ensure that Docker starts automatically when your system boots, run the following command:\n\n\n\n
\n
sudo systemctl enable docker<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis will configure Docker to start automatically each time your system starts up.\n\n\n\n
Step 8: Upgrading Docker Engine<\/h2>\n\n\n\n To upgrade Docker Engine to a newer version, simply update your package index and install the latest version:\n\n\n\n
\n
sudo apt-get update\nsudo apt-get upgrade docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nThis will upgrade Docker to the latest version available in the repository.\n\n\n\n
Uninstalling Docker Engine<\/h2>\n\n\n\n If you ever need to uninstall Docker, you can do so with the following command:\n\n\n\n
\n
sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nIf you want to remove all Docker data, including images, containers, and volumes, you can do so by running:\n\n\n\n
\n
sudo rm -rf \/var\/lib\/docker\nsudo rm -rf \/var\/lib\/containerd<\/code><\/pre>\n \n Copy<\/button>\n <\/amp-iframe>\n <\/div>\n\n\n\nConclusion<\/h2>\n\n\n\n Congratulations!
