setting up file.d on k8s

    git clone https://github.com/ozontech/file.d.git
ln -s file.d/charts/filed file-d-helm
cd file-d-helm/
    helm dependency update

    #minikube delete --all
    minikube start --driver=docker --container-runtime=containerd
    kubectx
    kubens -c

kubectl get clusterrole | grep cluster-admin
# same namespace as the one you're going to launch the helm in
namespace=default
    kubectl create clusterrolebinding file-d-test \
            --clusterrole=cluster-admin --serviceaccount=$namespace:file-d-test
kubectl get clusterrolebinding | grep test

vi values-custom.yaml

see file-d-test.yaml

    helm install file-d-test ./ --values=values-custom.yaml
    kubectl get pods | grep test

# sa got created by helm
kubectl get serviceaccount

# pod points to this sa
pod=`kubectl get pods | grep test | head -1 | awk '{print $1}'`
    kubectl get pod $pod -o yaml | grep service

watch -n1 kubectl get pods
watch -n1 kubectl logs $pod --tail=20

    #helm upgrade file-d-test ./ --values=values-custom.yaml
    #helm uninstall file-d-test

additional notes

if you just prefer to decode everything at once, whatever the log field looks like, do not enable error mode

  - type: json_decode
    field: log
    # this produces too much errors when log field is not nested
    #log_json_parse_error_mode: withnode
