Docker : Solr not getting deployed UnknownHostError

flowthinks — Sun, 01 Nov 2020 22:41:17 GMT

Hi Everyone!

I am just trying to get this project going for a POC. But I am having trouble with solr. It keeps throwing errors. I followed the instructions stated on this read me https://github.com/Alfresco/alfresco-docker-installer but I end up getting the error below

2020-11-01 22:15:50.018 ERROR (org.alfresco.solr.AlfrescoCoreAdminHandler@648ee871_Worker-27) [ ] o.a.s.t.ShardStatePublisher Unable to publish this node state. A failure condition has been met during the outbound subscription message encoding process. See the stacktrace below for further details.
java.net.UnknownHostException: alfresco
...

Please see ther solr portion of the docker-compose file below. What should the property SOLR_ALFRESCO_HOST be assigned to? alfresco is definately not a host, I see where the error is going with this.

solr6:
        build:
          context: ./search
          args:
            SEARCH_TAG: $SEARCH_CE_TAG
            SOLR_HOSTNAME: solr6
            ALFRESCO_HOSTNAME: localhost
            ALFRESCO_COMMS: none
            CROSS_LOCALE: "true"
        mem_limit: 1184m
        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"
            SOLR_SOLR_PORT: "8983"
            #Create the default alfresco and archive cores
            SOLR_CREATE_ALFRESCO_DEFAULTS: "alfresco,archive"
            SOLR_JAVA_MEM: "-Xms928m -Xmx928m"
            SOLR_OPTS: "
                -XX:NewSize=336m
                -XX:MaxNewSize=336m
            "
        volumes: 
            - ./data/solr-data:/opt/alfresco-search-services/data

I can't figure out what is missing.

I initially followed the solution that I accepted here. That document at least got me to the point of actually reaching the login screen but I could not login because of the same exception that I posted above.

Need to move forward with this. SEND HELP!

Hi @flowthinks

This is looking more like an Alfresco repo rather than a SOLR issue.

Could you report on what the Alfresco log is reporting?

Thanks,

Can you share the full docker-compose.yml file generated via alfresco-docker-installer tool?

I would recommed to use this docker-compose.yml file: https://github.com/Alfresco/acs-community-deployment/blob/master/docker-compose/docker-compose.yml

and see if everything works as expected. Then go back to the tool only if you have requirement such as ssl, proxy, ftp etc. types of specific needs.

Hi @EddieMay Below is the installer input I gave. Initially the acs version was 6.2. Downgraded but that did not help.

This is the output when I ran the start script

I am not sure how you checked the docker-compose.yml living here: https://github.com/Alfresco/acs-community-deployment/blob/master/docker-compose/docker-compose.yml

There is a major difference between what you shared and this

However, based on the logs you have shared it looks like the alfresco container did not start correctly. This could be likely due to memory issues.

Can you run following commands and share what you see?

To see what all containers running:

docker ps

OR To see all containers including the exited containers:

docker ps -a

check resources:

docker stats

Minimum 12GB or more, memory is required depending on the memory limits set in the docker compose file.

Some details can be found here as well:

That is correct. Thank you. My RAM allocation to docker is inefficient.

Glad to hear that you are able to figure out the issue. Good luck.

I had similar issues. Using the current specifications for community-docker-compose.yml solved it for me. Also if the docker engine is having less space then maybe increasing the resource space can also help.
