class=\"wp-block-paragraph\">Modern applications often consist of multiple components.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a web application may require:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A web server<\/li>\n\n\n\n<li>An application server<\/li>\n\n\n\n<li>A database<\/li>\n\n\n\n<li>A caching service<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Managing each container individually can become difficult as applications grow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Docker Compose simplifies this process by allowing the entire environment to be defined in a single configuration file.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Docker_Compose_Works\"><\/span>How Docker Compose Works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Docker Compose uses a YAML configuration file, typically named:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>docker-compose.yml\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This file defines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Services<\/li>\n\n\n\n<li>Container images<\/li>\n\n\n\n<li>Networks<\/li>\n\n\n\n<li>Environment variables<\/li>\n\n\n\n<li>Volumes<\/li>\n\n\n\n<li>Port mappings<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When Docker Compose starts the application, it automatically creates and connects all required components according to the configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Concepts\"><\/span>Key Concepts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Services\"><\/span>Services<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A service represents a containerized component of an application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Web servers<\/li>\n\n\n\n<li>Databases<\/li>\n\n\n\n<li>Application runtimes<\/li>\n\n\n\n<li>Reverse proxies<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Each service usually runs in its own container.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Networks\"><\/span>Networks<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p

class=\"ez-toc-section\" id=\"Volumes\"><\/span>Volumes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Volumes provide persistent storage that remains available even when containers are recreated.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Environment_Variables\"><\/span>Environment Variables<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Configuration settings can be passed to containers without modifying application code.<\/p>\n\n\n\n<h2

class=\"wp-block-paragraph\"><strong>Docker Compose \u2260 Docker<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Docker is the container platform itself.<\/p>\n\n\n\n<p
