Deployment for 2021

Requirements

• OpenShift Cluster 4.6+
• OpenShift CLI (oc)
• Knative CLI (kn)
• Make

Usage

1. Create an Environment File

Copy the .env.example into a file named .env. This will be used by the various scripts to inject variables into their deployments.

The OC_ variables require a token and cluster API URL. This is the target OpenShift cluster that services will be deployed onto.

OC_URL=https://the-cluster.openshiftapps.com:6443
OC_TOKEN=sha256~thisis-atoken-itsrandom # to be used instead of OC_USER and OC_PASSWORD

The cluster name is important for a multi-cluster demo. It will be used to tag outgoing payloads, i.e data sent to an off-cluster Kafka instance will be tagged as being from the "Americas" cluster.

CLUSTER_NAME="Americas"

Variables used to connect to the (possibly external) Kafka service.

KAFKA_SVC_USERNAME=srvc-acct-xxx-yyy-zzz-123
KAFKA_BOOTSTRAP_URL=some-name-abc.kafka.devshift.org:443
KAFKA_SVC_PASSWORD=1pass2goes-here-abcd-1b743

This controls Node.js application behaviours. Specifically, the game WebSocket Server will send game records to S3 (if AWS variables are defined), enable trace logging, and enable player vs. player matches if this is set to "dev"

NODE_ENV="prod"
AWS_ACCESS_KEY_ID=abc123
AWS_SECRET_ACCESS_KEY=123+abc

The admin application is used to control game state, e.g for dramatic pause during a demo. This is protected via basic authentication with a username and password.

ADMIN_USERNAME=admin
ADMIN_PASSWORD=secretsauce

2. Deploy the Services

Make is used to deploy everything. It's important that Data Grid is deployed prior to the backend and frontend components.

make datagrid && \
make serverless && \
make backend && \
make ai && \
make kafka-forwarder \
make frontend

3. Deploy Kafka Streams

This service only needs to be deployed in a single cluster since it aggregates data from all of the clusters.

If using a Kafka instance with self-signed certificates you'll need to copy a trustore containing the certificate to the kafka-streams/ folder.

NOTE: All jks files in the repo are ignored by gitignore.

cp $PATH_TO_A_TRUSTSTORE kafka-streams/truststore.jks

Update the .env with TRUSTSTORE_PASSWORD set to the password for the truststore.jks you copied, then run:

make kafka-streams
