How to run Docker nginx image

Now you pulled image, it is time to run it:
docker run --name my-nginx-c1 --detach nginx
Say you want to host simple static file hosted in /home/vivek/html/ using nginx container:
docker run --name my-nginx-c2 -p 80:80 -v /home/vivek/html/:/usr/share/nginx/html:ro -d nginx
Where,

--name my-nginx-c1 : Assign a name to the container
--detach : Run container in background and print container ID
-v /home/vivek/html/:/usr/share/nginx/html:ro : Bind mount a volume
-p 80:80 : Publish a container's port(s) to the host i.e redirect all traffic coming to port 80 to container traffic

Go ahead and create a file named index.html in /home/vivek/html/:
echo 'Welcome. I am Nginx server locked inside Docker' > /home/vivek/html/index.html
Test it:

curl http://your-host-ip-address/
curl 192.168.122.188

Sample outputs:

Welcome. I am Nginx server locked inside Docker

How to list running Docker containers

docker ps
docker ps -a

Sample outputs:

CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                NAMES

You can use CONTAINER ID to stop, pause or login into the container.

How to run a command in a running container

Run ls /etc/nginx command for my-nginx-c1 container
docker exec fe0cdbc0225a ls /etc/nginx
OR
docker exec my-nginx-c1 ls /etc/nginx
Want to gain bash shell for a running container and make changes to nginx image?
docker exec -i -t fe0cdbc0225a bash
OR
docker exec -i -t my-nginx-c1 bash

How to stop running containers

OR
docker stopfe0cdbc0225a
