Argo installation (locally)

Prerequisites

Minikube with VirtualBox

Argo

Getting started

In brief:

Download Argo

On Mac: brew install argoproj/tap/argo

On Linux: curl -sSL -o /usr/local/bin/argo https://github.com/argoproj/argo/releases/download/v2.1.1/argo-linux-amd64 && chmod +x /usr/local/bin/argo

Install the Controller and UI

argo install

Configure the service account to run workflows

kubectl create rolebinding default-admin --clusterrole=admin --serviceaccount=default:default

Launch UI

kubectl patch svc argo-ui -n kube-system -p '{"spec": {"type": "LoadBalancer"}}'

minikube service -n kube-system --url argo-ui

Artifacts repository (Minio)

We need a repository for artifacts in order to donwload the sources and to share them between the different steps of a workflow.

Prerequisites

Helm

install Minio

helm init
helm install stable/minio --name argo-artifacts --set service.type=LoadBalancer

Create a bucket named my-bucket from the Minio UI.

Reconfigure the workflow controller to use the Minio artifact repository

Edit the workflow-controller config map to reference the service name (argo-artifacts-minio) and secret (argo-artifacts-minio) created by the helm install:

kubectl edit configmap workflow-controller-configmap -n kube-system

...
    executorImage: argoproj/argoexec:v2.1.1
    artifactRepository:
      s3:
        bucket: my-bucket
        endpoint: argo-artifacts-minio.default:9000
        insecure: true
        # accessKeySecret and secretKeySecret are secret selectors.
        # It references the k8s secret named 'argo-artifacts-minio'
        # which was created during the minio helm install. The keys,
        # 'accesskey' and 'secretkey', inside that secret are where the
        # actual minio credentials are stored.
        accessKeySecret:
          name: argo-artifacts-minio
          key: accesskey
        secretKeySecret:
          name: argo-artifacts-minio
          key: secretkey

Minio UI

minikube service --url argo-artifacts-minio

AccessKey: AKIAIOSFODNN7EXAMPLE

SecretKey: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

Basic worflow definition to build

the worflow definition submit basic-gradle-build.yaml gets 2 parameters as input:

• the repo URL (public)
• the refs to build

These parameters must have a default value

By default it checkout the master branch of https://github.com/SonarSource/sonar-dummy-oss.git

Build master branch of sonar-dummy-oss

argo submit basic-gradle-build.yaml

Build tag 2.5.0.985 of sonar-dummy-oss

argo submit basic-gradle-build.yaml -p revision=refs/tags/2.5.0.985

Build sonar-go

argo submit basic-gradle-build.yaml -p repo=https://github.com/SonarSource/sonar-go.git

Build sonarqube

argo submit basic-gradle-build.yaml -p repo=https://github.com/SonarSource/sonarqube.git

Basic worflow definition to build and conditionally (using a parameter) run QA

Tests reports are archived in a Minio bucket.

By default it checkout the master branch of https://github.com/SonarSource/sonar-go.git

Limitations: sharing gradle project cache dir and sources between build and QA steps with a volume (Gradle specific)

K8s created volumes in container with root ownership and stric permissions

SQ (specificaly ES) cannot run with root user. So we cannot run tests with the default user of openjdk images

Gradle run with user gradle and then cannot:

• initiate the project (<project root dir>/.). Workaound is to use the CLI option --project-cache-dir=<other dir>
• write in the volume

Then we have to send artifacts to Artifactory in the build step and retrieve them in QA step.

As an other consequence of the permission on volume permission (and then artifacts management by Argo) and that we cannot run QA with root user, we have to checkout the sources by our own in QA step.

Using Secrets to push to Artifactory

Create a new secret named artifactory with url=http://localhost:8081, repo=libs-snapshot-local, user=admin, password=admin APIkey=key:

kubectl create secret generic artifactory --from-literal=url=http://localhost:8081 --from-literal=repo=libs-snapshot-local --from-literal=user=admin --from-literal=password=admin --from-literal=APIkey=key

Build master branch of sonar-go

argo submit basic-gradle-build-contitional-qa.yaml

Build and qualified master branch of sonar-go

argo submit basic-gradle-build-contitional-qa.yaml -p qa=true
