Docker networks feature overview This sections explains how to use the Docker networks feature. This feature allows users to define their own networks and connect containers to them. Using this feature you can create a network on a single host or a network that spans across multiple hosts. Understand Docker container networks Work with network commands Get started with multi-host networking If you are already familiar with Docker’s default bridge network, docker0 that network continues to be

Seccomp security profiles for Docker Secure computing mode (Seccomp) is a Linux kernel feature. You can use it to restrict the actions available within the container. The seccomp() system call operates on the seccomp state of the calling process. You can use this feature to restrict your application’s access. This feature is available only if Docker has been built with seccomp and the kernel is configured with CONFIG_SECCOMP enabled. To check if your kernel supports seccomp: $ cat /boot/config-

Install Docker Machine On OS X and Windows, Machine is installed along with other Docker products when you install the Docker Toolbox. For details on installing Docker Toolbox, see the Mac OS X installation instructions or Windows installation instructions. If you want only Docker Machine, you can install the Machine binaries directly by following the instructions in the next section. You can find the latest versions of the binaries are on the docker/machine release page on GitHub. Installing

Provision a Swarm cluster with Docker Machine You can use Docker Machine to provision a Docker Swarm cluster. Machine is the Docker provisioning tool. Machine provisions the hosts, installs Docker Engine on them, and then configures the Docker CLI client. With Machine’s Swarm options, you can also quickly configure a Swarm cluster as part of this provisioning. This page explains the commands you need to provision a basic Swarm cluster on a local Mac or Windows computer using Machine. Once you u

Frequently Asked Questions (FAQ) If you don’t see your question here, feel free to submit new ones to docs@docker.com. Or, you can fork the repo and contribute them yourself by editing the documentation sources. How much does Engine cost? Docker Engine is 100% free. It is open source, so you can use it without paying. What open source license are you using? We are using the Apache License Version 2.0, see it here: https://github.com/docker/docker/blob/master/LICENSE Does Docker run on Mac OS X

Evaluate Swarm in a sandbox This getting started example shows you how to create a Docker Swarm, the native clustering tool for Docker. You’ll use Docker Toolbox to install Docker Machine and some other tools on your computer. Then you’ll use Docker Machine to provision a set of Docker Engine hosts. Lastly, you’ll use Docker client to connect to the hosts, where you’ll create a discovery token, create a cluster of one Swarm manager and nodes, and manage the cluster. When you finish, you’ll have

Store images on Docker Hub So far you’ve learned how to use the command line to run Docker on your local host. You’ve learned how to pull down images to build containers from existing images and you’ve learned how to create your own images. Next, you’re going to learn how to use the Docker Hub to simplify and enhance your Docker workflows. The Docker Hub is a public registry maintained by Docker, Inc. It contains images you can download and use to build containers. It also provides authenticati

Exoscale Create machines on exoscale. Get your API key and API secret key from API details and pass them to machine create with the --exoscale-api-key and --exoscale-api-secret-key options. $ docker-machine create --driver exoscale --exoscale-api-key=API --exoscale-api-secret-key=SECRET vm Options: --exoscale-url: Your API endpoint. --exoscale-api-key: required Your API key. --exoscale-api-secret-key: required Your API secret key. --exoscale-instance-profile: Instance profile. --exoscale-

list — List the nodes in a cluster Use list to display a list of the nodes in a cluster. To list the nodes in a cluster, use the following syntax: docker run swarm list [OPTIONS] <discovery> The following examples show a few different syntaxes for the <discovery> argument: etcd: swarm list etcd://<etcd_addr1>,<etcd_addr2>/<optional path prefix> <node_ip:port> Consul: swarm list consul://<consul_addr>/<optional path prefix> <node_ip:port>
