Unlike virtual machines, containers share the host OS kernel, making them faster to start, smaller in size, and more resource-efficient.</p> <p>A Docker container bundles:</p> <ul> <li>Application code</li> <li>Runtime environment</li> <li>System libraries and dependencies</li> <li>Configuration files</li> </ul> <p>This means: <em>&ldquo;Build once, run anywhere.&rdquo;</em></p>
