Building a Container using kaniko

  1. Go into the proper folder

    cd ~/gitops-demo/docker-build-kaniko

  2. First create a kubernetes secret with docker registry credentials

    kubectl create secret docker-registry regcred --docker-server=<your-registry-server> --docker-username=<your-name> --docker-password=<your-pword> --docker-email=<your-email>
    • Expected Output:
    secret/regcred created

  3. Deploy the pod

    kubectl create -f build-kaniko.yaml
    • Expected Output:
    pod/kaniko created

  4. Test during build process

    kubectl logs pod/kaniko
    • Expected output:

Counting objects: 100% (14/14), done.
Compressing objects: 100% (11/11), done.
