Elastic in Docker 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
