Hello,
I am following this guide in order to get SSL installed:
> **[Configuring SSL, TLS, and HTTPS to secure Elasticsearch, Kibana, Beats, and...](https://www.elastic.co/blog/configuring-ssl-tls-and-https-to-secure-elasticsearch-kibana-beats-and-logstash)**
>
> Feeling insecure about your Elastic Stack security? Run through these step-by-step instructions for setting up TLS encryption and https on Elasticsearch, Kibana, Logstash, and Beats to shore up your stack's defenses. Highly recommended for end-to-end...
When I reach to point 2-4 and run the following command:
bin/elasticsearch-certutil cert ca --pem --in ~/tmp/cert\_blog/instance.yml --out ~/tmp/cert\_blog/certs.zip
I get the following exception:
```

HI, welecome
Can you provide your instance.yml file please ?
