Create a Dockerfile using the uppercase "D"

FROM nginx:latest
MAINTAINER Big Whale

ADD ./index.html /usr/share/nginx/html/index.html
EXPOSE 80

Create a sample index file to copy into the container

Build an image using the Dockerfile.

$ docker build .                     
Sending build context to Docker daemon  64.99MB

Check if container exists. Will not at this stage, you have only built the image.

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

Check images. You can see the unlabelled images.

$ docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             SIZE
<none>                             <none>              f6de3106be76        19 seconds ago      109MB

Create a container using the image you have built.

$ docker run -d -p 80:80 f6de3106be76
df1103871cb2b6a15b33aa9e24f0669e193fcfe52ef79d739ae90223c067ebf9

Check your index.html file was copied to the container.

$ curl http://localhost:80
