Index and Document

• Index and Document
  
• The process of inserting data/documents is called as indexing
• Lets refer the elastic search rest api’s Refer Here
• Refer Here for index apis
• Lets create curl request to create the index

ESPASS='nplUwdODeH4xtPfp=CT2'
SERVER_URL='https://20.198.70.188:9200'
# Checking if the index exists
curl -I -u elastic:$ESPASS "${SERVER_URL}/sample" --insecure
# we got 404 response => index not found

* Lets create one more index with
* name: sample2
* number of shards 1
* number of replicas 1

Exercise:

• Create an index with yourname
• Check if the index exists or not
• delete the index
  
• The commands used are

curl -I -u elastic:$ESPASS "https://20.198.70.188:9200/khajaibrahim?pretty" --insecure
curl -X DELETE -u elastic:$ESPASS "https://20.198.70.188:9200/khajaibrahim?pretty" --insecure
curl -I -u elastic:$ESPASS "https://20.198.70.188:9200/khajaibrahim?pretty" --insecure

• Now let me insert a document about Devops

{
    "name": "DevOps",
    "tools": ["Git", "Ansible", "Jenkins", "Docker", "K8s", "Terraform", "SRE"]
}

• The curl request is

curl -X POST -u elastic:$ESPASS "https://20.198.70.188:9200/khajaibrahim/_doc?routing=kimchy&pretty" -H 'Content-Type: application/json' --insecure -d'
{
    "name": "DevOps",
    "tools": ["Git", "Ansible", "Jenkins", "Docker", "K8s", "Terraform", "SRE"]
}
