Hi, everybody.

I have a problem with elasticsearch 8 and docker, which I am sitting on last 3-4 hours.

I have next docker compose configuration which consist of php symfony application and elasticsearch single node with security enabled options.

```auto
version: '2.2'

services:

  php_symfony_application:
    build: ./ci/php
    container_name: "php_symfony_application"
    volumes:
      - .:/var/www/php_symfony_application

  setup:
    image: docker.elastic.co/elasticsearch/elasticsearch:${STACK_VERSION}
    container_name: "udemy_phpes_setup"
    volumes:
      - certs:/usr/share/elasticsearch/config/certs
    user: "0"
    command: >
      bash -c '
        if [x${ELASTIC_PASSWORD} == x]; then
          echo "Set the ELASTIC_PASSWORD environment variable in the .env file";
          exit 1;
        fi;
        if [! -f certs/ca.zip]; then
          echo "Creating CA";
          bin/elasticsearch-certutil ca --silent --pem -out config/certs/ca.zip;
          unzip config/certs/ca.zip -d config/certs;
        fi;
        if [! -f certs/certs.zip]; then
          echo "Creating certs";
          echo -ne \
          "instances:\n"\
          " - name: elasticsearch8\n"\
          " dns:\n"\
          " - elasticsearch8\n"\
          " - localhost\n"\
          " ip:\n"\
          " - 127.0.0.1\n"\
          > config/certs/instances.yml;
          bin/elasticsearch-certutil cert --silent --pem -out config/certs/certs.zip --in config/certs/instances.yml --ca-cert config/certs/ca/ca.crt --ca-key config/certs/ca/ca.key;
          unzip config/certs/certs.zip -d config/certs;
        fi;
        echo "Setting file permissions"
        chown -R root:root config/certs;
        find . -type d -exec chmod 750 \{\} \;;
        find . -type f -exec chmod 640 \{\} \;;
        echo "Waiting for Elasticsearch availability";
        until curl -s --cacert config/certs/ca/ca.crt https://elasticsearch8:9200 | grep -q "missing authentication credentials"; do sleep 30; done;
        echo "All done!";
      '
    healthcheck:
      test: ["CMD-SHELL", "[ -f config/certs/elasticsearch8/elasticsearch8.crt]" ]
      interval: 1s
      timeout: 5s
      retries: 120

  elasticsearch8:
    depends_on:
      setup:
        condition: service_healthy
    image: docker.elastic.co/elasticsearch/elasticsearch:${STACK_VERSION}
    container_name: "elasticsearch8"
    volumes:
      - certs:/usr/share/elasticsearch/config/certs
      - ./ci/data/es/db:/usr/share/elasticsearch/data
    ports:
      - ${ES_PORT}:9200

    environment:
      - node.name=elasticsearch8
      - cluster.name=${CLUSTER_NAME}
      - cluster.initial_master_nodes=elasticsearch8
      - ELASTIC_PASSWORD=${ELASTIC_PASSWORD}
      - bootstrap.memory_lock=true
      - xpack.security.enabled=true
      - xpack.security.http.ssl.enabled=true
      - xpack.security.http.ssl.key=certs/elasticsearch8/elasticsearch8.key

      - xpack.security.transport.ssl.verification_mode=certificate
      - xpack.license.self_generated.type=${LICENSE}
    ulimits:
      memlock:
        soft: -1
        hard: -1
    healthcheck:
      test:
        [
            "CMD-SHELL",
            "curl -s --cacert config/certs/ca/ca.crt https://localhost:9200 | grep -q 'missing authentication credentials'",
        ]
      interval: 10s
      timeout: 10s
      retries: 120

volumes:
  certs:
    driver: local

```

I can connect from local machine with curl using certificate:

```auto
 curl --cacert path/to/ca.crt -u elastic:test1234 https://localhost:9202/_cluster/health?prett

```

All works in that case as it should be.

But while being inside php application container and running the curl with certificate:

```auto
curl --cacert path/to/ca.crt -u elastic:test1234 https://elasticsearch8:9200/_cluster/health?pretty

```

I am getting the error:

**curl: (35) error:14094417:SSL routines:ssl3\_read\_bytes:sslv3 alert illegal parameter**

As result (at least I suppose it is the reason) while trying to connect to the cluster via elasticsearch-php client with next code:

```auto
$client = ClientBuilder::create()
    ->setHosts(['https://elasticsearch8:9200'])
    ->setBasicAuthentication('elastic', 'test1234')
    ->setCABundle('path/to/http_ca.crt')
    ->build();

```

I am getting the error: "No alive nodes. All the 1 nodes seem to be down."

Seems it is some issue related to the docker,dns and certificates altogether. I completely stuck with that and have no more ideas how to resolve the problem.

Can anybody save my day? I would be very grateful for any ideas.  
Thanks
