In this guide we're going to take you through the fundamentals of 9 using Docker and integrating it into your environment. 10 11 We’ll teach you how to use Docker to: 12 13 * Dockerize your applications. 14 * Run your own containers. 15 * Build Docker images. 16 * Share your Docker images with others. 17 * And a whole lot more! 18 19 We've broken this guide into major sections that take you through 20 the Docker life cycle: 21 22 ## Getting started with Docker Hub 23 24 *How do I use Docker Hub?* 25 26 Docker Hub is the central hub for Docker. It hosts public Docker images 27 and provides services to help you build and manage your Docker 28 environment. To learn more: 29 30 Go to [Using Docker Hub](/userguide/dockerhub). 31 32 ## Dockerizing applications: A "Hello world" 33 34 *How do I run applications inside containers?* 35 36 Docker offers a *container-based* virtualization platform to power your 37 applications. To learn how to Dockerize applications and run them: 38 39 Go to [Dockerizing Applications](/userguide/dockerizing). 40 41 ## Working with containers 42 43 *How do I manage my containers?* 44 45 Once you get a grip on running your applications in Docker containers 46 we're going to show you how to manage those containers. To find out 47 about how to inspect, monitor and manage containers: 48 49 Go to [Working With Containers](/userguide/usingdocker). 50 51 ## Working with Docker images 52 53 *How can I access, share and build my own images?* 54 55 Once you've learnt how to use Docker it's time to take the next step and 56 learn how to build your own application images with Docker. 57 58 Go to [Working with Docker Images](/userguide/dockerimages). 59 60 ## Linking containers together 61 62 Until now we've seen how to build individual applications inside Docker 63 containers. Now learn how to build whole application stacks with Docker 64 by linking together multiple Docker containers. 65 66 Go to [Linking Containers Together](/userguide/dockerlinks). 67 68 ## Managing data in containers 69 70 Now we know how to link Docker containers together the next step is 71 learning how to manage data, volumes and mounts inside our containers. 72 73 Go to [Managing Data in Containers](/userguide/dockervolumes). 74 75 ## Working with Docker Hub 76 77 Now we've learned a bit more about how to use Docker we're going to see 78 how to combine Docker with the services available on Docker Hub including 79 Trusted Builds and private repositories. 80 81 Go to [Working with Docker Hub](/userguide/dockerrepos). 82 83 ## Docker Compose 84 85 Docker Compose allows you to define a application's components -- their containers, 86 configuration, links and volumes -- in a single file. Then a single command 87 will set everything up and start your application running. 88 89 Go to [Docker Compose user guide](/compose/). 90 91 ## Docker Machine 92 93 Docker Machine helps you get Docker Engines up and running quickly. Machine 94 can set up hosts for Docker Engines on your computer, on cloud providers, 95 and/or in your data center, and then configure your Docker client to securely 96 talk to them. 97 98 Go to [Docker Machine user guide](/machine/). 99 100 ## Docker Swarm 101 102 Docker Swarm pools several Docker Engines together and exposes them as a single 103 virtual Docker Engine. It serves the standard Docker API, so any tool that already 104 works with Docker can now transparently scale up to multiple hosts. 105 106 Go to [Docker Swarm user guide](/swarm/). 107 108 ## Getting help 109 110 * [Docker homepage](http://www.docker.com/) 111 * [Docker Hub](https://hub.docker.com) 112 * [Docker blog](http://blog.docker.com/) 113 * [Docker documentation](http://docs.docker.com/) 114 * [Docker Getting Started Guide](http://www.docker.com/gettingstarted/) 115 * [Docker code on GitHub](https://github.com/docker/docker) 116 * [Docker mailing 117 list](https://groups.google.com/forum/#!forum/docker-user) 118 * Docker on IRC: irc.freenode.net and channel #docker 119 * [Docker on Twitter](http://twitter.com/docker) 120 * Get [Docker help](http://stackoverflow.com/search?q=docker) on 121 StackOverflow 122 * [Docker.com](http://www.docker.com/) 123
