# By default, only basic components are deployed

# If not already set, set the tag you want to use for your images.

# - If CRDB_DEPLOY_MODE is "single", CockroachDB is deployed in single node mode. It is convenient for
#   development and testing purposes and should fit in a VM. IT SHOULD NOT BE USED IN PRODUCTION ENVIRONMENTS.
# - If CRDB_DEPLOY_MODE is "cluster", CockroachDB is deployed in cluster mode, and an entire CockroachDB cluster
#   with 3 replicas and version v22.2 (set by default) will be deployed. It is convenient for production and
#   provides scalability features. If you are deploying for production, also read the following link providing
