Prometheus Monitoring for Containerized Applications

Monitor your Docker containers using prometheus, cAdvisor , node-exporter and grafana

Prerequisites:

• Docker CE, Docker EE, or Docker Desktop on Windows
• docker-compose

Setup and Deploy the monitoring stack

1. Clone this repo:

   git clone https://github.com/jmb12686/prometheus-monitoring
   cd prometheus-monitoring

2. Change line #5 in the alert.rules.yml file to correspond to a container name that you want to explicitly monitor and fire alerts for. Change name="YOUR-CONTAINER-NAME-HERE" to match your Docker container NAME.

3. Start the stack with docker-compose:

   docker-compose up

   If launching from a Windows host, be sure to set the following Docker-Compose variable in powershell first:

   $Env:COMPOSE_CONVERT_WINDOWS_PATHS=1
