Run OpenSearch for Marqo on a port other than 9200 about marqo HOT 2 CLOSED

I found 3 solutions:

1. Change the host port to a port of your preference: docker run -p <host port>:<container port> -p 9600:9600 -e “discovery.type=single-node” opensearchproject/opensearch:2.1.0. In my case I ran: docker run -p 9000:9200 -p 9600:9600 -e “discovery.type=single-node” opensearchproject/opensearch:2.1.0. (this is my preferred option)
2. Or, configure the http.port attribute in elasticsearch.yml that’s usually found in /etc/elasticsearch/elasticsearch.yml.
3. Or, you can temporarily stop Elasticsearch service running on port 9200 using sudo kill -9 $(sudo lsof -t -i:9200). Then proceed with running the docker OpenSearch command found in the README

I changed the port used in the marqo client as well. In my case I did mq = marqo.Client(url='https://localhost:9000/', main_user="admin", main_password="admin").

from marqo.

Thanks Vivien, option 1 is probably the easiest for users, as the fix is to change the docker run port binding!
