Docker is a powerful tool that lets you package and run applications in lightweight, portable containers.<\/strong><\/p>\n\n\n\n Instead of installing software directly on your system, Docker lets you run everything in isolated environments\u2014so it\u2019s cleaner, faster, and works the same on any machine. Whether you’re building apps, testing code, or deploying to production, Docker simplifies the process and saves you tons of setup time.<\/p>\n\n\n\n To install Docker Engine, you\u2019ll need a 64-bit version<\/strong> of one of the following Ubuntu releases<\/strong>:<\/p>\n\n\n\n Docker supports multiple system architectures, including:<\/p>\n\n\n\n Make sure your system matches one of these versions and architectures before proceeding with the installation.<\/p>\n\n\n\n Ensure your system packages are up to date before installing Docker.<\/p>\n\n\n\n Install tools needed to work with external repositories over HTTPS.<\/p>\n\n\n\n Add Docker\u2019s secure key to verify packages from their repository.<\/p>\n\n\n\n Add the Docker repository to your system\u2019s software sources.<\/p>\n\n\n\n Update your system again to include Docker\u2019s packages.<\/p>\n\n\n\n Install the Docker runtime and command-line tools.<\/p>\n\n\n\n Verify that Docker was installed successfully.<\/p>\n\n\n\n Make sure Docker is working by running the Hello World image.<\/p>\n\n\n\n Starting with Docker might feel like learning a new language at first, but once you get the basics, it becomes an incredibly powerful tool in your development toolkit.PREREQUISITES:<\/strong><\/h2>\n\n\n\n
