kubectl create namespace argocd helm repo add argo https://argoproj.github.io/argo-helm helm repo update helm install argocd argo/argo-cd --namespace argocd

We will use Helm to install Argo CD with the community-maintained chart from argoproj/argo-helm because The Argo project doesn't provide an official Helm chart. We will render thier helm chart for argocd locally on our side, manipulate it and overrides its default values, and also we can helm lint the chart and templating to see if there is some errors or not, We gonna use the chart version 5.50.0 which matches appVersion: v2.8.6 you can find all details for the chart and also we gonna override some values @ default-values.yaml

resource "helm_release" "argocd" { name = "${var.environment}-argocd" namespace = "${var.environment}-argocd" create_namespace = true repository = "https://argoproj.github.io/argo-helm" version = "${var.helm_version}" chart = "argo-cd" set { name = "server.service.type" value = "LoadBalancer" } set { name = "server.service.loadBalancerIP" value = "${var.loadBalancerIP}" } values = [ <<-YAML --- global: image: tag: "${var.image_tag}" configs: repositories: gitops-homelab: url: [email protected]:myprivaterepo/gitops-homelab.git name: private-repo type: git sshPrivateKey: file("${path.module}/sa_keys/private/${var.environment}_id_rsa") server: extraArgs: - --insecure YAML ] } output "file_location" { value = file("${path.module}/sa_keys/private/${var.environment}_id_rsa") }

"argo-cd" = { repository = "https://argoproj.github.io/argo-helm", chart = "argo-cd", namespace = "argocd" values_file = templatefile("./values/argocd.yml", { ingress_scheme = "internal" #internet-facing or internal elb_name = aws_lb.this["${local.name}-int-a"].name })

repository = "https://argoproj.github.io/argo-helm" chart = "argo-cd" namespace = "argo" version = "5.34.5"

I think your example with the ArgoCD Helm chart says it all. It can get incredibly complicated, and I had tremendous trouble getting it working, it broke all the time, getting the indentation right was a nightmare ... very unpleasant experience. I mean look at that chart, the authors have to constantly specify the indentation level everywhere.

plugin: name: argocd-vault-helm env: - name: release_name value: argocd - name: chart_name value: argo-cd - name: chart_repo value: https://argoproj.github.io/argo-helm - name: chart_version value: 5.17.1 - name: chart_values value: -f applicationset.yaml -f configs.yaml -f controller.yaml -f dex.yaml -f redis.yaml -f reposerver.yaml -f server.yaml -f notifications.yaml - name: args value: --include-crds

Another folder I want to discuss shortly is the Terraform folder. This project was installed by terraform basically but it can deployed easily with simple helm installation of ArgoCD . In the next attachment we can see the relevant values neccesary to apply our ArgoCD system : values-override.tpl

Finally, we have to install ArgoCD from the official Helm Chart but with extra configuration that provides modifications required to install Vault plugin via sidecar container.

This is a GitHub link to my demo app. It’s simple Spring Boot web app used to debugging various stuff. There are many ways to configure JSON logging in Spring Boot. I decided to use Logback because it is easy to configure and one of the most widely used logging library in the Java Community. To enable JSON logging we need to add below dependencies.

My demo app (GitHub Link) uses Spring Boot version 3, or more precisely the latest release from 2022, i.e. 3.0.1. The core monitoring component in Spring Boot is Actuator. If you remember the migration of Spring Boot from version 1 to 2, you’ll probably remember that update brought a lot of breaking changes in Actuator. Fortunately, in the case of version 3, no such changes have been made, so you can apply the following configurations to Spring Boot version 2.x.x
