Docker version 1.12 it was the only native Docker option for clustering hosts, and it needed a lot of additional setup for distri buted state, service discovery and security. Serial number for illustrator cc mac. Swarm Mode With Docker 1.12,(is built into Docker Engine) To run a cluster you just need to install Docker on multiple machines, run docker swarm init to switch to Swarm.

Advanced Docker Commands Cheat Sheet. Bellow are some advanced docker commands cheat sheet: 21. Using multiple Docker Compose Files. These Cheat Sheet Docker Commands use multiple docker files a developer must change the application with its environments, staging and production. Docker Cheat Sheet Process Management # Show all running docker containers docker ps # Show all docker containers docker ps -a # Run a container docker run: # Run a container and connect to it docker run -it: # Run a container in the background docker run -d: # Stop a container docker stop.

On the other hand, some misconfigurations can lead to downgrade the level of security or even introduce new vulnerabilities. The aim of this cheat sheet is to provide an easy to use list of common security mistakes and good practices that will help you secure your Docker containers.

Docker’s purpose is to build and manage compute images and to launch them in a container. So, the most useful commands do and expose this information.

Here’s a cheat sheet on the top Docker commands to know and use.

Docker Cheat Sheet 2020

Images and containers

The docker command line interface follows this pattern:
docker <COMMAND>

The docker images and container commands grant access to the images and containers. From here, you are permitted to do something with them, hence:

There are:

• is lists the resources.
• cp copies files/folders between the container and the local file system.
• create creates new container.
• diff inspects changes to files or directories in a running container.
• logs fetches the logs of a container.
• pause pauses all processes within one or more containers.
• rename renames a container.
• run runs a new command in a container.
• start starts one or more stopped containers.
• stop stops one or more running containers.
• stats displays a livestream of containers resource usage statistics.
• top displays the running processes of a container.

View resources with ls

From the container ls command, the container id can be accessed (first column).

Control timing with start, stop, restart, prune

• start starts one or more stopped containers.
• stop stops one or more running containers.
• restart restarts one or more containers.
• prune (the best one!) removes all stopped containers.

Name a container

View vital information: Inspect, stats, top

• stats displays a live stream of container(s) resource usage statistics

• top displays the running processes of a container:

• inspect displays detailed information on one or more containers. With inspect, a JSON is returned detailing the name and states and more of a container.

Additional resources

For more on this topic, there’s always the Docker documentation, the BMC DevOps Blog, and these articles:

This is just a cheat sheet of commands and terminology for Docker and ASP.NET Core; it contains commands that you can find in the original cheat sheet, plus a Dockerfile for ASP.NET Core and a quick guide on how to created one from Visual Studio. Hopefully, both developers that are in the process of getting into the containerize world with Docker and developers that are already in but need a quick recap will find it useful.

Basic terminology

Term	Short explanation
Docker	Docker is a set of platform as a service products that uses OS-level virtualization to deliver software in packages called containers. Download Docker for Windows here.
Image	An image, or more correct, a Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
Container	A container image becomes a container at runtime when they run on Docker Engine
Docker Engine	Docker Engine is a container runtime that runs on various Linux (CentOS, Debian, Fedora, Oracle Linux, RHEL, SUSE, and Ubuntu) and Windows Server operating systems…
Docker Hub	Docker Hub is a service provided by Docker for finding and sharing container images with your team.
Dockerfile	A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image.

Basic commands

Follows, a list of basic commands that you will regularly need. Run them using command line from the root of your application – where the Dockerfile should exists.

Term	Short explanation
docker pull	Retrieve an image from a registry. If you specify only the repository name, Docker will download the image tagged latest from that repository on Docker Hub. e.g. docker pull mcr.microsoft.com/dotnet/core/aspnet:3.1 pulls the 3.1 runtime, where docker pull mcr.microsoft.com/dotnet/core/sdk pulls the latest .NET Core SDK.
docker build	Create a new image by running a Dockerfile. User the -t flag to specify the name of the new image and don’t forget the . (build context for the source files for the COPY command) e.g. docker build -t image.name.for.my.app:v1 .
docker image list	After pulling an image, view the images in your local registry with the docker image list command.
docker ps	View active containers. Use the -a flag to view all. e.g. docker ps -a
docker run	Run an image – it will become a container. Specify the option -p for port mapping (left hand side local port, right hand side port exposed by docker) and -d to run it as a background service. Speficy the --name option to set the name of the container. e.g. docker run -p 8080:80 -d --name container.name image.name.for.my.app
docker stop	Stop an active container by specifying the container ID. Get that with the docker ps command e.g. docker stop elegant_ramanujan
docker start	Restart a stopped container. e.g. docker start elegant_ramanujan
docker container rm	Remove a stopped container. Add the -f flag to force remove a running container (not a graceful shutdown) e.g. docker container rm -f elegant_ramanujan
docker image rm	Remove an image. There is no force flag here, all containers using this image must be stopped. e.g. docker image rm mcr.microsoft.com/dotnet/core/samples:aspnetapp

A Dockerfile sample

Living in the root of the application, a Dockerfile is just a plain text file; you can either use the following command to create it in Windows, or anyway you like: copy NUL Dockerfile. The sample below contains everything necessary to build and run an image. Comments above each command attempt to provide a bit of clarity:

If it happens to have a Visual Studio around, just right click on your main project, select ‘Add’ and then ‘Docker Support…’:

Docker Run Flags

Usually, for ASP.NET Core, I choose ‘Linux’ as Operating System; at the end it comes cheaper if you want to host it, for example, in Azure.
