Docker delivers software in containers, which simplifies the process by packaging everything it takes to run an application. With Docker growing in popularity, it becomes necessary to understand it before using it on your own or for a business. Windows Containers (personal) cheat sheet. The container had nothing exposed to the standard output, so when you started the container or tried to see the logs via docker logs nothing was there. Build docker image PS cd path to Dockerfile PS docker build. View running processes. PS docker ps View all processes. PS docker ps -a Run an image in a new container daemonized. PS docker run -d Run an image in interactive mode with the command powershell.exe. PS docker run -i -t powershell.exe. Docker cheat sheet Introduction. Docker is a tool for bundling together applications and their dependencies into images that can than be run as containers on many different types of computers.
Docker command:docker run [options] image-name [command] [arg]
Example: Running a container from the image alpine.
| docker run image-name | docker run image-name command | docker run image-name command arg |
docker run alpine | docker run alpine ls | docker run alpine ping 192.168.3.1 |
Common options:

Example. Building an image from a Dockerfile in the current directory:docker build .
- The command assumes that a file named Dockerfile is in the current directory.
Common options:
| Tag the image | Name of the Dockerfile |
docker build -t my-image:latest . | docker build -f my-dockerfile . |
| List all images | List images (no intermediate) | Remove an image |
docker image ls -a | docker image ls | docker image rm my-image |
| Remove dangling images | Remove unused images | Show the history of an image |
docker image prune | docker image prune -a | docker history my-image |
In a Dockerfile the following main keywordsare used:
