Hi ,

network.host: ["0.0.0.0", 127.0.0.1", "[::1]"]
network.bind_host: 0.0.0.0
network.publish_host: 0.0.0.0
http.host: 0.0.0.0
http.cors.enabled : true
http.cors.allow-origin : "*"
http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length

After adding above in was getting below error

[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

For error reolution , I have configured below

I did try this option and set below property

I did not mean to bypass the bootstrap checks. I think it's important that you fix the actual problems.
So read https://www.elastic.co/guide/en/elasticsearch/reference/current/_file_descriptor_check.html and its solution here: https://www.elastic.co/guide/en/elasticsearch/reference/current/file-descriptors.html

If you still have an error, please share all the logs.
