Solr6 Behind NgInx

[rstoops]

Hi guys,

I'm attempting to work with a docker-compose file to put 2 solr6s behind it.

I've added another NgInx to the compose file for the purposes of load balancing the solrs. Everything starts but looking at the admin console, it is not showing Tracking status for solr.

I'm looking to see if someone has an example of this.  My nginx.conf file for solr looks as follows:

worker_processes  1;

events { 
    worker_connections 1024; 
}

http {
    upstream solrlb {
        server solr6-1:8084;
    }

    server {
        listen *:8983;
        server_name solrlb;

        location / {
            proxy_pass http://solrlb;
            proxy_set_header Host $host;
            #proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
    }
}

My section for solr in the compose file (3.7 level)

    solr6-1:
        image: alfresco/alfresco-search-services:1.4.2
        deploy:
            resources:
                limits:
                    memory: 2048M
                reservations:
                    memory: 2048M
        environment:
            #Solr needs to know how to register itself with Alfresco
            - SOLR_ALFRESCO_HOST=alfresco
            - SOLR_ALFRESCO_PORT=8080
            #Alfresco needs to know how to call solr
            - SOLR_SOLR_HOST=solr6-1
            - SOLR_SOLR_PORT=8983
            #Create the default alfresco and archive cores
            - SOLR_CREATE_ALFRESCO_DEFAULTS=alfresco,archive
            #HTTP by default
            - ALFRESCO_SECURE_COMMS=none
            - "SOLR_JAVA_MEM=-Xms2g -Xmx2g"
        ports:
            - 8084:8983 #Browser port

    solr-balancer:
        image: alfresco/alfresco-acs-nginx:3.0.1
        deploy:
            resources:
                limits:
                    memory: 128M
                reservations:
                    memory: 128M
        depends_on:
            - solr6-1
        ports:
            - 8983:8983
        volumes:
            - type: bind  
              source: /Users/rstoops/dev/projects/alfresco6_docker_compose/solr-nginx.conf
              target: /etc/nginx/nginx.conf

Thanks in advance.

You can use https://github.com/Alfresco/alfresco-docker-installer as reference.

Thanks Angel.  I ran the utility and even though solr is behind nginx my goal is to have multiple solr6 which is why I was heading do the path of nginx "upstream" to add a 2nd solr box once I got the first one working.

Can you help with or another resource for this problem?

Thanks again.

Angel,

Disregard, I've got it configured.

Hi @rstoops 

Great news! If you have time to update us on how you resolved it that would be great too!

This is what is working for the moment but I need to do more testing.
