I've installed the DataDog agent on my Kubernetes cluster using the Helm chart (https://github.com/helm/charts/tree/master/stable/datadog).
This works very well except for one thing. I have a number of Redis containers that have passwords set. This seems to be causing issues for the DataDog agent because it can't connect to Redis without a password.
I would like to either disable monitoring Redis completely or somehow bypass the Redis authentication. If I leave it as is I get a lot of error messages in the DataDog container logs and the redisdb integration shows up in yellow in the DataDog dashboard.
What are my options here?
I am not a fan of helm, but you can accomplish this in 2 ways:
via env vars: make use of DD_AC_EXCLUDE variable to exclude the Redis containers: eg DD_AC_EXCLUDE=name:prefix-redis
via a config map: mount an empty config map in /etc/datadog-agent/conf.d/redisdb.d/, below is an example where I renamed the auto_conf.yaml to auto_conf.yaml.example.
apiVersion: v1
data:
auto_conf.yaml.example: |
ad_identifiers:
- redis init_config: instances:
## @param host - string - required
## Enter the host to connect to.
#
- host: "%%host%%" ## @param port - integer - required
## Enter the port of the host to connect to.
#
port: "6379"
conf.yaml.example: |
init_config: instances: ## @param host - string - required
## Enter the host to connect to.
