Push Images

cd /opt/lighthouse/downloads   #/opt/lighthouse is the directory where Lighthouse platform is located
# Note: Please replace the registry address (need to add project name, e.g., 192.168.2.99/light-agent); if username and password are required, add -u and -p parameters
REGISTRY_REPO=your_docker_registry_url ./image-pusher.sh -- -u <username> -p <password>

Deploy light-agent

Execute the following operations in the Kubernetes environment to deploy light-agent

Get Kubernetes Deployment Script Template light-agent-template.yaml

curl -O http://<Lighthouse IP>/downloads/k8s/light-agent-template.yaml

Get Docker Configuration Secret

  1. Create Secret
Note
  • --docker-email: Please replace with your email
  • --docker-username: Please replace with your username
  • --docker-password: Please replace with your password
  • --docker-server: Please replace with your registry address (no need to add project name, e.g., 192.168.2.99)
kubectl create secret docker-registry dockerconfig-secret \
  --docker-email=<email> \
  --docker-username=<username> \
  --docker-password=<password> \
  --docker-server=<registry_url>
  1. Get Secret

  • REGISTRY_CRED: Please replace with the dockerconfig-secret obtained in the previous step
  • envsubst: Environment variable replacement tool. Variables contained within do not need to be modified
COLLECTOR_SERVER_IP=<Lighthouse IP> REGISTRY_REPO=<your_docker_registry_url> REGISTRY_CRED=<registry_crea_str> envsubst '${REGISTRY_REPO} ${COLLECTOR_SERVER_IP} ${REGISTRY_CRED}' <light-agent-template.yaml >light-agent.yaml

Execute Installation

kubectl apply -f light-agent.yaml

Check Status
