application together with all of its dependencies, libraries, and configuration files into a single container.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A container runs consistently regardless of where it is deployed, whether on a developer&#8217;s computer, a testing environment, or a production server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key Docker components include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Docker Engine \u2013 the software that runs containers<\/li>\n\n\n\n<li>Docker Images \u2013 templates used to create containers<\/li>\n\n\n\n<li>Docker Hub \u2013 a public repository of ready-to-use container images<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Docker is commonly used for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Local development environments<\/li>\n\n\n\n<li>Testing applications<\/li>\n\n\n\n<li>Running websites and web applications<\/li>\n\n\n\n<li>Hosting databases and supporting services<\/li>\n\n\n\n<li>Simplifying software deployment<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">One of Docker&#8217;s biggest advantages is that it eliminates the classic &#8220;it works on my machine&#8221; problem by ensuring applications run the same way everywhere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Kubernetes\"><\/span>What Is Kubernetes?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Kubernetes (often abbreviated as K8s) is a container orchestration platform originally developed by Google.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of managing individual containers manually, Kubernetes automates deployment, scaling, monitoring, networking, and recovery across multiple servers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kubernetes can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deploy containers automatically<\/li>\n\n\n\n<li>Restart failed containers<\/li>\n\n\n\n<li>Distribute traffic between instances<\/li>\n\n\n\n<li>Scale applications up and down<\/li>\n\n\n\n<li>Manage updates with minimal downtime<\/li>\n\n\n\n<li>Maintain high availability<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Kubernetes is typically used in larger environments where applications consist of multiple services and need to remain available even during heavy traffic or hardware failures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

containers on a server<\/li>\n\n\n\n<li>Isolating applications from the host system<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Docker is ideal when you want to run one application or a small

of Docker as a shipping container.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The container packages everything needed to transport goods safely and consistently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kubernetes is the logistics company that manages thousands of those containers, deciding:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Where they should

uploaded to a container registry such as Docker Hub.<\/li>\n\n\n\n<li>Kubernetes retrieves the image and deploys containers across a cluster.<\/li>\n\n\n\n<li>Kubernetes monitors the containers and automatically responds to failures or traffic increases.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">In this process:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Docker provides the

Docker packages and runs applications in containers, while Kubernetes manages those containers across one or more servers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For most developers and hosting users, Docker provides everything needed to deploy and run applications efficiently. Kubernetes becomes valuable when applications grow in complexity and require automated scaling, fault tolerance, and large-scale infrastructure management.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than replacing one another, Docker and Kubernetes are often used together, with Docker handling application packaging and Kubernetes handling deployment, scaling, and orchestration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"template":"","format":"standard","manualknowledgebasecat":[28],"manual_kb_tag":[4347,4348,4349,4350,4351,4352,4353,4354,4355,4356],"class_list":["post-10510","manual_kb","type-manual_kb","status-publish","format-standard","hentry","manualknowledgebasecat-others","manual_kb_tag-docker","manual_kb_tag-kubernetes","manual_kb_tag-containerization","manual_kb_tag-container-orchestration","manual_kb_tag-containers","manual_kb_tag-docker-engine","manual_kb_tag-docker-images","manual_kb_tag-docker-hub","manual_kb_tag-container-registry","manual_kb_tag-microservices"],"_links":{"self":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/10510","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb"}],"about":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/types\/manual_kb"}],"author":[{"embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":1,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/10510\/revisions"}],"predecessor-version":[{"id":10511,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/10510\/revisions\/10511"}],"wp:attachment":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/media?parent=10510"}],"wp:term":[{"taxonomy":"manualknowledgebasecat","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manualknowledgebasecat?post=10510"},{"taxonomy":"manual_kb_tag","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb_tag?post=10510"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
