GettingStarted.md

Pre-flight Check

List currently running containers:

docker ps

List locally available images:

docker images

Run

Run an nginx container:

docker run --name example1 -d -p 9898:80 nginx

• --name give the container a unique name of example1
• -d run nginx as a daemon
• -p map the container port 80 to the host port 9898

If you navigate to http://localhost:9898, you should be able to see the default nginx page.

Inspect

List currently running containers:

docker ps

Inspect container to get details and properties:

docker inspect example1

Get container logs i.e. your application logs:

docker logs example1

Exec into the container using the provided command. In this case we will launch a bash shell.

docker exec -it example1 /bin/bash

Once in the container, list the running processes, look around and exit:

$ ps auwx
$ ....
$ exit

Stop and remove the container:

docker rm -f example1

Modify

Build a custom image with our Dockerfile to be run as a contianer:

docker build -t myimage .

Our new image by the name of myimage now contains a custom page for nginx. We can now use the run command to launch our newly built image:

docker run --name example2 -d -p 9898:80 myimage
