Can't access Elastic Search after installing using Docker Desktop on Mac-CodePudding

I'm on mac. Try to run Elastic Search use Docker Desktop. Below is the commands I ran. I have no problem to run query in Kibana, the problem is I can't connect to Elastic Search via localhost:9200. Please help!!

    $docker network create elastic

    $docker pull docker.elastic.co/elasticsearch/elasticsearch:8.1.2 

    $docker run --name es-node01 --net elastic -p 9200:9200 -p 9300:9300 -t docker.elastic.co/elasticsearch/elasticsearch:8.1.2

    $docker pull docker.elastic.co/kibana/kibana:8.1.2

     $docker run --name kib-01 --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:8.1.2

CodePudding user response：

Please remember to be specific in your questions. "Can't connect" - what happens when you try to connect?

If what you get is

curl: (52) Empty reply from server

The problem is that elasticsearch 8.0 defaults to turning security on, so you need a certificate and a password.

Full instructions are on the elasticsearch website

But the two steps that are new are:

Copy the certificate:

docker cp es01:/usr/share/elasticsearch/config/certs/http_ca.crt .

and use the certificate and the password with curl:

curl --cacert http_ca.crt -u elastic https://localhost:9200

You will be prompted for a password. The password is printed when your Elasticsearch instance starts. Yes, it's buried in the log output, but there are blank lines, it's not hard to find. It looks like:

-> Elasticsearch security features have been automatically configured!
-> Authentication is enabled and cluster connections are encrypted.

->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  PLoSd-3iJTncwmdSAwaku

->  HTTP CA certificate SHA-256 fingerprint:
  722460137abbd54249a056698d4ac3d05495de9c18e7ac4aba9e3e07814fe3c79

There is an extra step (and the same user (elastic) and password to access kibana.
