I was playing with the Harmony project and they mentioned that it's now achievable since openedx/edx-search#130 and openedx/cs_comments_service#404, but I didn't find any configurations related to a Prefix for elastic indices. Is this feature implemented or only cs_comment support it and should we modify the plugin?
I've got the same question for tutor-discovery and any other plugins which are using Elastic Search.
@ghassanmas please implement the changes recommended in this PR: overhangio/tutor-ecommerce#34
mongodb+srv urls are introduced in this PR: #10
But querystring parameters will not work in the forum because of the way the MONGOHQ_URLvariable is generated:
MONGOHQ_URL="$MONGODB_HOST/$MONGODB_DATABASE"
We need to modify the definition of MONGOHQ_URL such that querystring parameters are supported. If possible, we should take this opportunity to get rid of the forum entrypoint entirely.
See overhangio/tutor#1004 for the context.
I am trying to connect the forum docker with MongoDB cluster.
The configurations are -
environment:
SEARCH_SERVER: "http://elasticsearch:9200"
MONGODB_USERNAME: "mongouser"
MONGODB_PASSWORD: "password"
MONGODB_HOST: "mongo_primary_host_url"
MONGODB_PORT: 27017
MONGODB_DATABASE: "cs_comments_service"
MONGOID_USE_SSL: true
MONGOID_SSL_VERIFY: true
MONGOID_READ_MODE: "primary"
MONGOID_AUTH_MECH: ":mongodb_x509"
MONGOID_SSL_CA_CERT: "My_certificate_path_in_the_forum_docker"
MONGOID_TIMEOUT: 10
This is the error i get in the forum.

Can follow the previous conversation here.
To create a MongoDB cluster
First we need to enable replSet.
mongod --port 27017 --replSet rs0
or you can add it in the configuration file /etc/mongod.conf.
replication:
replSetName: rs0
Make sure the three nodes are having the same replSetName.
Follow this link to setup replset.
Enable authentication and ssl/tls certificated.
security:
authorization: enabled
tls:
mode: requireTLS
certificateKeyFile: /etc/ssl/mongodb.pem
Follow these links to setup authentication and ssl/tls.
https://hevodata.com/learn/mongodb-configuration-file/
https://www.mongodb.com/docs/manual/tutorial/configure-ssl/
Make sure to have all the 3 nodes to have the security, authentication and ssl/tls enabled.
After the nodes are ready to connect in replset state.
Connect the nodes with each other.
To connect all the 3 nodes with each other. Login to one of the Mongodb shell.
rs.initiate()
rs.add('ip1:port1')
rs.add('ip2:port2')
rs.add('ip3:port3')
rs.status()
Follow this to connect all the three nodes.
Note - I am working on a completly cloud based cluster. I do not need to manually setup everything. But for development purposes we need to do them manually.
When we make small changes to the docker-entrypoint.sh script (as we did in this PR #10), the Docker image needs to be rebuilt almost from scratch. This because the following statement:
COPY ./bin /app/bin
is located before the rest of the Dockerfile instructions (including git clone ... etc.).
I suggest either to:
COPY statement closer to the ENTRYPOINT statement.Building the image fails on Arm based arch/(e.g Apple silicon), due to gem lock file not supporting the platform/arch.

To reproduce, just build the image tutor images build forum on a device which is not Arch x86.
The suggested fix above does fix it, however it's better to resolve the issue upstream @ https://github.com/openedx/cs_comments_service.
From https://discuss.openedx.org/t/tutor-cs-comment-service-mongo-and-ruby-upgrade/12472 :
We just tested and landed this change 3 which has confirmed that the latest version of cs_comment_service will work with Ruby 3.3 and Mongo 7.
I don’t know what is involved but the relevant tutor code and images should be updated.
If this is using the same Mongo instance as the LMS/CMS, then maybe hold off on the mongo upgrade there until chore: add mongo 7 to testing matrix by DanielVZ96 · Pull Request #34213 · openedx/edx-platform · GitHub 1 merges which will hopefully be soon!
