    Hands-On GitOps Patterns for Helm Users


Install Flux CLI and Kind:
$ brew reinstall flux kind
$ kind --version
kind version 0.10.0
$ flux --version
flux version 0.9.1


Make Personal Access Token for creating repositories

Check all permissions under repo
Copy PAT to buffer


Export env vars locally
$ export GITHUB_TOKEN=[paste PAT]


Create local demo cluster
$ kind create cluster
(took 27s)


Simple bootstrap:
the more complex your org is, the more complex your directory structure and patterns are
there is no gold standard
flux is not opinionated about how directories are structured, rather it tries to be as flexible as possible to accommodate different patterns
$ flux bootstrap github --owner scottrigby --personal  --repository hands-on-gitops-patterns-for-helm-users --branch main --path=clusters/dev
► connecting to github.com
✔ repository created
✔ repository cloned
✚ generating manifests
✔ components manifests pushed
► installing components in flux-system namespace
…
◎ verifying installation
✔ install completed
► configuring deploy key
✔ deploy key configured
► generating sync manifests
✔ sync manifests pushed
► applying sync manifests
◎ waiting for cluster sync
✔ bootstrap finished

Clone the newly created git repo to your local workspace
$ cd ~/code/github.com/scottrigby
$ git clone git@github.com:scottrigby/hands-on-gitops-patterns-for-helm-users.git
$ tree
.
├── README.md
└── clusters
    └── dev
        └── flux-system
            ├── gotk-components.yaml
            ├── gotk-sync.yaml
            └── kustomization.yaml


Create a Source Custom Resource locally
$ flux create source helm podinfo \
--url=https://stefanprodan.github.io/podinfo \
--interval=10m \
--export > clusters/dev/source-helmrepo-podinfo.yaml


Create a Helm Release Custom Resource locally in the "app1" namespace dir
$ flux create hr app1 \
--interval=10m \
--source=HelmRepository/podinfo \
--chart=podinfo \
--chart-version=">4.0.0" \
--export > ./clusters/dev/podinfo-helmrelease.yaml


From this point on, you are now doing GitOps:
$ git add .
$ git commit -m 'Configure podinfo Helm Repo source and app1 Helm Release'
$ git push


Cleanup demo cluster
$ kind delete cluster
