I use Windows 8.1 for Docker.
After installation when I tried to run docker, for example docker run hello-world from cmd I received the following error:
C:\Program Files\Docker Toolbox\docker.exe: An error occurred trying to connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.23/containers/create: open //./pipe/docker_engine: The system cannot find the file specified..
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
Run docker on Windows with start.sh script from Docker installation directory.
Output would be like following:
## .
## ## ## ==
## ## ## ## ## ===

docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com
Start interactive shell
devneo@host MINGW64 ~
$
If you get error about certification, try to regenerated them (default is the default VM name):
$ docker-machine regenerate-certs -f default
When I tried to access terminal on a container I got following error:
$ docker run -it hello-world
cannot enable tty mode on non tty inputTo solve this problem I logged into default VM via ssh using docker-machine, then run container from there:
$ docker-machine ssh default

| `docker commit <shortId | name> repo/image:tag` | commits container changes as an image |
| `docker stop <shortId | name>` | stops container, useful to stop detached container |
docker exec -i -t repo/image:tag cmd |
start a new process for container, when exits doesn't stops main container with PID 1 | docker exec -i -t ubuntu:latest bash |
| `docker rm <shortId | name>` | removes a container |
docker tag image:tag repo/user/image:tag |

docker load -i image.tar |
loads saved image into docker | docker load -i my_webserver_1.0.tar |
docker build -t image:tag path |
build image according to Dockerfile located in path | docker build -t umidjons/myapp:latest . |
docker run -v locPath:contPath image cmd |
mounts local path to the specified container's path | docker run -i -t -p 3000:3000 -v /c/Users/umidjons/projects/myapp/:/var/www/myapp umidjons/myapp:4.7 node /var/www/myapp/server.js |

docker run -d --net=<networkName> --name <containerName> <image> |
run container with specifying network | docker run -d --net=mynetwork --name mymongodb mongo docker run -d --net=mynetwork --name nodeapp -p 80:3000 node from now inside nodeapp container we can use host name mymongodb as they are in the same network |
docker-compose build |
build containers from docker-compose.yml file |
|

up built containers according to docker-compose.yml |
|
docker-compose up -d |

|
docker-compose down |
tear down (also removes containers) running containers | |
docker-compose ps |
show information about running containers | |
docker-compose logs |
show logs from all running containers |
Run docker on external 8080 port, map that port into internal 3000 port on the container, create volum that points current directory into containers /var/www directory, then with -w set working directory in the container to /var/www, run node image with command node app.js:
docker run -p 8080:3000 -v $(pwd):/var/www -w "/var/www" node:6 node app.js
many tanks for tips 😄 👍
