# The above installation puts a default config file in
|
|
# /etc/mongodb-mms/monitoring-agent.config
|
|
# It should contain a line like: "mmsApiKey="
|
|
# i.e. with no value specified.
|
|
# We need to set that value to the "agent API key" value from Cloud Manager,
|
|
# but of course that value varies from user to user,
|
|
# so we can't hard-code it into the Docker image.
|
|
|
|
# Kubernetes can set an MMS_API_KEY environment variable
|
|
# in the container
|
|
# (including from Secrets or ConfigMaps)
|
|
# An entrypoint bash script can then use the value of MMS_API_KEY
|
|
# to write the mmsApiKey value in the config file
|
|
# /etc/mongodb-mms/monitoring-agent.config
|
|
# before running the MongoDB Monitoring Agent.
|
|
|
|
# The MongoDB Monitoring Agent has other
|
|
# config settings besides mmsApiKey,
|
|
# but it's the only one that *must* be set. See:
|
|
# https://docs.cloudmanager.mongodb.com/reference/monitoring-agent/
