This guide will walk you through the installation of FleetMD using Helm, including the setup of Redis and MySQL. You will prepare your Kubernetes environment, install Redis and MySQL using values.yaml, and finally deploy FleetMD.
Fleet is the main service that will be deployed as part of the FleetMD setup. It handles the core functionalities of FleetMD and interacts with both MySQL and Redis to store and retrieve data.
MySQL is used to store persistent data for FleetMD, including metadata, application data, and other critical records. A PersistentVolume and PersistentVolumeClaim are required for storing MySQL data.
Redis is used as a caching layer for FleetMD to improve performance. It stores temporary data like session information and other cached content.
Before installing FleetMD, ensure that your Kubernetes cluster is up and running and that Helm is installed.
First, create a dedicated Kubernetes namespace for FleetMD:
kubectl create namespace fleetChange HostPath path respectively to your environment.
Apply configuration for Redis and MySQL:
kubectl apply -f mysql/volume.yaml
kubectl apply -f redis/volume.yamlFleetMD requires Redis and MySQL secrets for secure access. You will need to create secrets for both services.
To create the Redis secret with the password, use the following command:
kubectl create secret generic redis-secrets \
--from-literal=redis-password=changemeCreate the MySQL secret for the root, user, and replication passwords:
kubectl create secret generic mysql-secrets \
--from-literal=mysql-root-password=changeme \
--from-literal=mysql-password=changeme \
--from-literal=mysql-replication-password=changemeYou can modify the changeme password to a more secure value of your choice.
Instead of passing parameters via the command line, you can use values.yaml files to configure the installations of Redis and MySQL.
helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update
helm install redis bitnami/redis --namespace fleet -f redis-values.yamlhelm install mysql bitnami/mysql --namespace fleet -f mysql-values.yamlThis will deploy MySQL with the specified root, user, and replication passwords, and will use the PersistentVolumeClaim mysql-pvc created earlier for storage.
Once the namespace, PV/PVC, secrets, and Redis/MySQL services are up and running, you can proceed with installing FleetMD.
First, add the Helm chart repository for FleetMD:
helm repo add fleetmd https://charts.fleetmd.io
helm repo updateNow, install the FleetMD Helm chart in the fleet namespace:
helm install fleetmd fleetmd/fleetmd --namespace fleetCheck the status of your deployment to ensure everything is running as expected:
kubectl get pods -n fleetOnce the installation is complete, you can access FleetMD using the appropriate service (e.g., via a load balancer, ingress, or NodePort). Refer to the FleetMD documentation for additional configuration steps.
This guide has provided the steps to install FleetMD, along with Redis and MySQL, on Kubernetes using Helm and values.yaml for configuration. Be sure to customize your passwords and storage paths as needed for your environment.
