> docker container run --name web -p 5000:80 alpine:3.9Run a container from the Alpine version 3.9 image, name the running container “web” and expose port 5000 externally, mapped to port 80 inside the container.
> docker container start webStart a stopped container named web.
> docker container lsList all running containers
> docker container ls -aList all containers (running and stopped)
> docker container run -it --name webserver nginxRun docker container nginx in interactive mode (-it). This allows to see the image output directly in the shell.
To have the complete control of the image (accessing it shell), we need to pass an argument (bash) to the image:
> docker container run -it --name webserver nginx bashTo access an already running docker image, we need to use exec command:
> docker container exec -it webserver bash-p source:dest makes a port forwarding from the image to localhost, so we can expose a port inside docker image (the port where the app/db/whatever is running inside the image) to a local port, and access to it.
> docker container port webservershows the port mapping of that container.
> docker container inspect webserverReturns a json formatted list of informations about selected container (config, newtwork, etc)it.
To filter only some needed informations, we can use --format argument:
docker container inspect --format '{{ .NetworkSettings.IPAddress}}' webhostReturn only the container's ip addres (see the json structure to understand how to get other infos).
