Using Docker Compose, you can connect all the isolated containers as a single service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The containers are still segregated, but they can interact with one another. A YAML file makes it possible to configure the services of your application. Then, with one command, you create and start all services from your configuration. With Docker Compose, you get the benefits of single host deployment, great security, and ease of set up &amp; configuration which leads to really high productivity and efficiency.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is Compose file?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>Compose file<\/strong> is a YAML file named:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>docker-compose.yml<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">(Default location: <code>.\/docker-compose.yml<\/code>)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It defines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Services (containers)<\/li>\n\n\n\n<li>Networks<\/li>\n\n\n\n<li>Volumes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Each service definition configures how a container is built, connected, and executed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Docker Compose Benefits:<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list has-normal-font-size\">\n<li>Fast and simple configuration<\/li>\n\n\n\n<li>Secure internal communication<\/li>\n\n\n\n<li>Portability and CI\/CD Support<\/li>\n\n\n\n<li>Efficient use of resources<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Docker Compose Features:<\/strong><\/h2>\n\n\n\n<ul id=\"block-8538b0a5-5268-4197-9644-0c682c21d589\" class=\"wp-block-list has-normal-font-size\">\n<li>Host multiple environments on one machine<\/li>\n\n\n\n<li>Support for environment variables<\/li>\n\n\n\n<li>Persistent volume data<\/li>\n\n\n\n<li>Reuse of existing containers<\/li>\n\n\n\n<li>Simplified multi-container orchestration<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How to Use Docker Compose<\/strong><\/h2>\n\n\n\n<h5 class=\"wp-block-heading\">1.
