Configuring SSL for Shinydocs Indexer

Requirements

• Elasticsearch & Kibana Free Tier (non-oss)

• Either:

  • .pk12 SSL certificate (preferred)

  • Generate a self-signed certificate with Elasticsearch

Steps for existing PK12 certificate

1. Create a folder called “certs” in ..\indexer\config\

   1. You should now have the path ..\indexer\config\certs

2. Add the following to elasticsearch.yml
   Replace elastic-certificates.p12 with the organizations .p12 file
   

   xpack.security.http.ssl.enabled: true
   xpack.security.http.ssl.keystore.path: certs/elastic-certificates.p12 
   xpack.security.http.ssl.truststore.path: certs/elastic-certificates.p12 
   

   
   

3. If the certificate has a password:

   1. Open CMD

   2. Use the cd command to navigate into ..\indexer\bin

   3. Run the following two commands, and provide the password each time
      

      elasticsearch-keystore.bat add xpack.security.http.ssl.keystore.secure_password
      elasticsearch-keystore.bat add xpack.security.http.ssl.truststore.secure_password
      

      
      

4. Restart Elasticsearch

Steps for generating a self-signed certificate with Elasticsearch

1. Create a folder called “certs” in ..\indexer\config\

   1. You should now have the path ..\indexer\config\certs

2. Open CMD and cd to ..\indexer\bin

3. Run the following to initiate key generation:
   

   elasticsearch-certutil.bat ca
   

   
   

4. Provide a name (that ends in .pk12) or press enter to use the default elastic-stack-ca.p12

5. Enter the desired password for the certificate (optional)

6. There will be a new file in ..\indexer\bin called elastic-stack-ca.p12, copy that file into ..\indexer\config\certs

7. Add the following to elasticsearch.yml
   

   xpack.security.http.ssl.enabled: true
   xpack.security.http.ssl.keystore.path: certs/elastic-stack-ca.p12 
   xpack.security.http.ssl.truststore.path: certs/elastic-stack-ca.p12
   

   
   

8. If the certificate has a password:

   1. Open CMD

   2. Use the cd command to navigate into ..\indexer\bin

   3. Run the following command, and provide the password for the key
      

      elasticsearch-keystore.bat add xpack.security.http.ssl.keystore.secure_password
      elasticsearch-keystore.bat add xpack.security.http.ssl.truststore.secure_password
      

      
      

9. Restart Elasticsearch

Adjust Kibana Config for SSL Elasticsearch

Now that Elasticsearch is on SSL, Kibana’s config will need to be updated to work with HTTPS

1. Change elasticsearch.hosts URL to https and uncomment the line if commented
   eg. elasticsearch.hosts: ["https://localhost:9200"]

2. If the certificate is self-signed, you will need to tell Kibana that it is okay to proceed. Modify elasticsearch.ssl.verificationMode to none
   eg. elasticsearch.ssl.verificationMode: none

3. Restart Kibana
