1. The following command demonstrates how to create a user.

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem https://xxx.xxx.xxx.xxx:9200/_plugins/_security/api/internalusers/my_user -H 'Content-Type: application/json' -d'
{
    "password": "my_password",
    "backend_roles": [],
    "attributes": {
        "attribute1": "value1",
        "attribute2": "value2"
    }
}'

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem https://xxx.xxx.xxx.xxx:9200/_plugins/_security/api/internalusers/my_user -H 'Content-Type: application/json' -d'

{

"password": "my_password",

"backend_roles": [],

"attributes": {

"attribute1": "value1",

"attribute2": "value2"

}

2. The following command demonstrates how to map a role to the user created above.

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem https://xxx.xxx.xxx.xxx:9200/_plugins/_security/api/rolesmapping/readall_and_monitor -H 'Content-Type: application/json' -d'
{
    "users" : [ "my_user" ]
}'

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem https://xxx.xxx.xxx.xxx:9200/_plugins/_security/api/rolesmapping/readall_and_monitor -H 'Content-Type: application/json' -d'

{

"users" : [ "my_user" ]

3. The following command demonstrates how to change the password for a user.

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem https://xxx.xxx.xxx.xxx:9200/_plugins/_security/api/internalusers/my_user -H 'Content-Type: application/json' -d'
{
    "password": "my_new_password"
}'

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem https://xxx.xxx.xxx.xxx:9200/_plugins/_security/api/internalusers/my_user -H 'Content-Type: application/json' -d'

{

"password": "my_new_password"

4. The following command demonstrates how to index a document (The index ‘testing’ will automatically be created if it does not exist).

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem "https://xxx.xxx.xxx.xxx:9200/testing/_doc/1?pretty" -H 'Content-Type: application/json' -d'
{
"description" : "this is a test",
"timestamp" : "2020-01-16T04:32:49"
}'

curl -X PUT -u icopensearch:<Password> --cacert cluster-ca-certificate.pem "https://xxx.xxx.xxx.xxx:9200/testing/_doc/1?pretty" -H 'Content-Type: application/json' -d'

{

"description" : "this is a test",

"timestamp" : "2020-01-16T04:32:49"

5. The following command demonstrates how to retrieve the document indexed in the previous step.

curl -u icopensearch:<Password> --cacert cluster-ca-certificate.pem "https://xxx.xxx.xxx.xxx:9200/testing/_doc/1?pretty"
