Deploy Morfeu in Kubernetes, using argo and argocd, tested on microk8s. Heavily leveraging workflow templates in Argo
To deploy on Kubernetes, using MicroK8s (https://microk8s.io/) on Ubuntu (v1.20.13), but it should work in any other Kubernetes setup.
Make sure the basic add-ons like dns, storage, registry and ingress are enabled. For reference, this is the list of add-ons:
`microk8s enable dashboard dns ha-cluster ingress metrics-server registry hostpath-storage`
First install argocd following the installation instructions in argocd/scratchpad.sh
Secondly install Argo workflows following the scratchpad at argo/scratchpad.sh
There are the following steps
- load-source
- checkout
- buildld
- redeploy
In this step, we use the artifact configuration to load the source folder from S3 (Minio) into a volume mount /source
The first time it will be empty and we create a /source/{{workflow.parameters.appName}}-source path inside, in
this way, we can support multiple application builds, though this can be changed if more separation of concerns is
needed.
The second time the workflow is executed, the source will already be there which we can re-use to just do a git pull
on and update the source as needed (see next step).
Make sure you create the target namespace first, namely:
kubectl create namespace morfeu
