ElasticSearch Container Exercise

Login into your sandbox

Shutdown host services to release memory:

sudo service elasticsearch stop
sudo service kibana stop
sudo service filebeat stop
sudo service logstash stop

Since previously installed Elastic is running, we will use a different port: 9201 for api

 sudo docker run -d -p 9201:9200 -e "http.host=0.0.0.0" -e "transport.host=127.0.0.1" docker.elastic.co/elasticsearch/elasticsearch:5.4.1

-d: run detached not to take over command prompt
-e: parameters accepted/expected by the image
Give it few moments to start and then test:

 curl elastic:changeme@localhost:9201

Expected output:

{
  "name" : "3kMnHFQ",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "E7Ag9a_1SX2FVPsMQGUCng",
  "version" : {
    "number" : "5.4.1",
    "build_hash" : "2cfe0df",
    "build_date" : "2017-05-29T16:05:51.443Z",
    "build_snapshot" : false,
    "lucene_version" : "6.5.1"
  },
  "tagline" : "You Know, for Search"
}

Using docker cli to list containers:
```
sudo docker ps -a
```
Expected output is list with two containers: hello-world and elastic
To stop running container, copy container id to replace in the command below:
```
sudo docker stop 8ed07e81b59c
```
Using docker cli to list containers to confirm none are running:
```
sudo docker ps -a
```
Expected output is a list of two containers previously launched: hello-world and elasticsearch
