Docker : Opensearch拒绝与docker中opensearch文档中的示例连接。

Question

我在docker容器上运行openSearchv1.0.0，在localhost上使用以下命令。请考虑这个问题，不是和这篇文章一样，未能建立新连接：[Errno 111]连接被拒绝)是因为失败的原因不同。

docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:1.0.0

我试图在opensearch 文档，中运行示例中的代码，而不使用ca_certs和ssl。

from opensearchpy import OpenSearch

host = 'localhost'
port = 9200
auth = ('admin', 'admin') # For testing only. Don't store credentials in code.
# ca_certs_path = '/full/path/to/root-ca.pem' # Provide a CA bundle if you use intermediate CAs with your root CA.

# Optional client certificates if you don't want to use HTTP basic authentication.
# client_cert_path = '/full/path/to/client.pem'
# client_key_path = '/full/path/to/client-key.pem'

# Create the client with SSL/TLS enabled, but hostname verification disabled.
client = OpenSearch(
    hosts = [{'host': host, 'port': port}],
    http_compress = True, # enables gzip compression for request bodies
    http_auth = auth,
    # client_cert = client_cert_path,
    # client_key = client_key_path,
    use_ssl = False,
    verify_certs = False,
    ssl_assert_hostname = False,
    ssl_show_warn = False,
    # ca_certs = ca_certs_path
)

# Create an index with non-default settings.
index_name = 'python-test-index'
index_body = {
  'settings': {
    'index': {
      'number_of_shards': 4
    }
  }
}

response = client.indices.create(index_name, body=index_body)
print('\nCreating index:')
print(response)

它给了我以下的错误。

ConnectionError: ConnectionError(('Connection aborted.', RemoteDisconnected('Remote end 
closed connection without response'))) caused by: ProtocolError(('Connection aborted.', 
RemoteDisconnected('Remote end closed connection without response')))

在此之后，我在终端上运行了以下命令，它给出了预期的输出，即OpenSearch在docker中运行得很好。

$ curl -XGET https://localhost:9200 -u 'admin:admin' --insecure

如何解决这个问题。

Answer 1

您正在设置use_ssl=False，但默认情况下，opensearch Docker映像似乎会创建opensearch服务器。当您尝试建立非SSL连接时，如果您查看容器日志，您可以看到这一点：

io.netty.handler.codec.DecoderException: io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record

如果我修改您的代码使其具有use_ssl=True，那么它将成功运行：

$ python opensearch_test.py
Loading .env environment variables...

Creating index:
{'acknowledged': True, 'shards_acknowledged': True, 'index': 'python-test-index'}
