Docker

Below are the instructions to install the Aperture Agent on Docker.

Prerequisites

1. Install Docker on your system.

Installation

1. Create a file named agent.yaml with below content for passing the configuration to the Aperture Agent:

   etcd:
     endpoints:
       - "ETCD_ENDPOINT_HERE"
   prometheus:
     address: "PROMETHEUS_ADDRESS_HERE"
   agent_functions:
     endpoints: ["CONTROLLER_ENDPOINT_HERE"]
   log:
     level: info
     pretty_console: true
     non_blocking: false
   otel:
     disable_kubernetes_scraper: true
     disable_kubelet_scraper: true
   auto_scale:
     kubernetes:
       enabled: false
   service_discovery:
     kubernetes:
       enabled: false

   Replace the values of ETCD_ENDPOINT_HERE and PROMETHEUS_ADDRESS_HERE with the actual values of etcd and Prometheus, which are also being used by the Aperture Controller you want these Agents to connect to. CONTROLLER_ENDPOINT_HERE should point to Aperture Controller. If you skip it, some sub-commands aperturectl commands won't work.

   If you have installed the Aperture Controller on the same Docker environment, with etcd and Prometheus, the values for the values for ETCD_ENDPOINT_HERE, PROMETHEUS_ADDRESS_HERE and CONTROLLER_ENDPOINT_HERE would be as below:

   etcd:
     endpoints:
       - "http://etcd:2379"
   prometheus:
     address: "http://prometheus:9090"
   agent_functions:
     endpoints: ["aperture-controller:8080"]
     client:
       grpc:
         insecure: true
   log:
     level: info
     pretty_console: true
     non_blocking: false
   otel:
     disable_kubernetes_scraper: true
     disable_kubelet_scraper: true
   auto_scale:
     kubernetes:
       enabled: false
   service_discovery:
     kubernetes:
       enabled: false

   All the configuration parameters for the Aperture Agent are available here.

2. Run the below command to start the Aperture Agent container:

   docker run -d \
   -p 8081:8080 \
   --name aperture-agent \
   --network aperture \
   -v "$(pwd)"/agent.yaml:/etc/aperture/aperture-agent/config/aperture-agent.yaml:ro \
   docker.io/fluxninja/aperture-agent:2.7.0

3. Verify that the Aperture Agent container is in the healthy state:

   docker run -it --rm \
   --network aperture curlimages/curl \
   sh -c \
   'while [[ \"$(curl -s -o /dev/null -w %{http_code} aperture-agent:8080/v1/status/system/readiness)\" != \"200\" ]]; \
   do echo "aperture-agent is starting"; sleep 1; done && \
   echo "aperture-agent is now healty!"'

Uninstall

1. Run the below command to stop and remove the Aperture Agent container:

   docker rm -f aperture-agent
