run an nginx container v

From your bash terminal, run an NGINX container and expose it at port 8080

docker container run -p 8080:80 -d nginx

test it:

Find the public IP of your Cloud9 environment:
Cloud9 environments are basically EC2instances. So, go to AWS https://eu-central-1.console.aws.amazon.com (you may have to change the region to the region where you started the Cloud9 environment) and find the EC2 instance that starts with "aws-cloud9-"
Find its IP address at the bottom half of the page under Details -> Instance summary
An easier way may be to run the following in your Cloud9 shell

myip="$(dig +short myip.opendns.com @resolver1.opendns.com)"
echo "My WAN/Public IP address: ${myip}"

In the Security Group for that EC2 instance, open port 8080 and port 8000 (for the next lab)
For the Source select "My IP", not "anywhere"
AWS Services -> ec2 -> select the EC2 instance of your cloud9 environment -> at the bottom part of the screen: open the Security tab -> click on the Security group -> Inbound Rules -> Edit inbound rules -> Add Rules
Save Rules securityGroups

From our workstation, browse to it: http://MY_IP:8080
welcomeToNginx

Find the container-ID of that container

docker ps

Run an Alpine container

docker run -d alpine
docker ps

Why don't you see the Alpine container?
try docker ps -a

docker ps -a

Can you explain what happened?

Find the images on your host

docker image ls

Let's deploy Splunk

Browse to https://hub.docker.com/ search for splunk
Locate the image splunk/splunk and click on it Scroll down to the "Quick Start" section and read it
Now, let's deploy it locally. For the password, use e.g. "Tr3ndm1cr0!"

$ docker run -d -p 8000:8000 -e "SPLUNK_START_ARGS=--accept-license" -e "SPLUNK_PASSWORD=Tr3ndmicro!" --name splunk splunk/splunk:latest

Port 8000 should already be opened in the Security Group in the previous step.
From your workstation, browse to it
It will be on the same IP as the Nginx, but on port 8000 splunk

Cleanup (optional)

Stop and delete all running containers

docker ps
docker stop [CONTAINER-ID]
docker rm [CONTAINER-ID] [CONTAINER-ID] [CONTAINER-ID]

Delete the images that you have created earlierGjensidige

docker image ls
docker rmi [IMAGE-ID] [IMAGE-ID] [IMAGE-ID]
