Overview Swarm with TLS All nodes in a Swarm cluster must bind their Docker daemons to a network port. This has obvious security implications. These implications are compounded when the network in question is untrusted such as the internet. To mitigate these risks, Docker Swarm and the Docker Engine daemon support Transport Layer Security (TLS). Note: TLS is the successor to SSL (Secure Sockets Layer) and the two terms are often used interchangeably. Docker uses TLS, this term is used througho

Understand images, containers, and storage drivers To use storage drivers effectively, you must understand how Docker builds and stores images. Then, you need an understanding of how these images are used by containers. Finally, you’ll need a short introduction to the technologies that enable both images and container operations. Images and layers Each Docker image references a list of read-only layers that represent filesystem differences. Layers are stacked on top of each other to form a base

exec Usage: exec [options] SERVICE COMMAND [ARGS...] Options: -d Detached mode: Run command in the background. --privileged Give extended privileges to the process. --user USER Run the command as this user. -T Disable pseudo-tty allocation. By default `docker-compose exec` allocates a TTY. --index=index index of the container if there are multiple instances of a service [default: 1] This is equivalent of docker e

Best practices for writing Dockerfiles Docker can build images automatically by reading the instructions from a Dockerfile, a text file that contains all the commands, in order, needed to build a given image. Dockerfiles adhere to a specific format and use a specific set of instructions. You can learn the basics on the Dockerfile Reference page. If you’re new to writing Dockerfiles, you should start there. This document covers the best practices and methods recommended by Docker, Inc. and the D

start Usage: docker start [OPTIONS] CONTAINER [CONTAINER...] Start one or more containers -a, --attach Attach STDOUT/STDERR and forward signals --detach-keys Specify the escape key sequence used to detach a container --help Print usage -i, --interactive Attach container's STDIN

start Usage: start [SERVICE...] Starts existing containers for a service.

Deploy your infrastructure In this step, you create several Docker hosts to run your application stack on. Before you continue, make sure you have taken the time to learn the application architecture. About these instructions This example assumes you are running on a Mac or Windows system and enabling Docker Engine docker commands by provisioning local VirtualBox virtual machines thru Docker Machine. For this evaluation installation, you’ll need 6 (six) VirtualBox VMs. While this example uses D

network inspect Usage: docker network inspect [OPTIONS] NETWORK [NETWORK..] Displays detailed information on a network -f, --format= Format the output using the given go template. --help Print usage Returns information about one or more networks. By default, this command renders all results in a JSON object. For example, if you connect two containers to the default bridge network: $ sudo docker run -itd --name=container1 busybox f2870c98fd504370fb86e59f32cd0753b1ac9b69

rm Usage: rm [options] [SERVICE...] Options: -f, --force Don't ask to confirm removal -v Remove any anonymous volumes attached to containers -a, --all Also remove one-off containers created by docker-compose run Removes stopped service containers. By default, anonymous volumes attached to containers will not be removed. You can override this with -v. To list all volumes, use docker volume ls. Any data which is not in a volume will be lost.

Docker Remote API client libraries These libraries make it easier to build applications on top of the Docker Remote API with various programming languages. They have not been tested by the Docker maintainers for compatibility, so if you run into any issues, file them with the library maintainers.
