+* Notes
+- Taints and tolerations will likely not work without at least 2 nodes.
+- Affinities based on hostnames will fail require matching names
+- Secrets are stored in [[https://app.infisical.com/][Infisical]] so the similar secret structure is required.
+
+** Software requirements
+- New enough ~kubectl~ to use ~kubectl ... -k~ for kustomize
+- [[https://github.com/casey/just][just]] to run deploy/redeploy commands
+- [[https://github.com/gopasspw/gopass][gopass]] with infisical ID+Secret under ~homelab/infisical/{id,secret}~
+
+** Usage
+These all leverage the kustomizations and shell scripts in ~deploy/~
+- ~just diff~     :: shows all changes based on kustomize
+- ~just apply~    :: apply all changes
+- ~just deploy~   :: apply all changes including infisical bootstrap secret
+- ~just redeploy~ :: as above but recreates the bootstrap secret from keepass
+- ~just infisical_bootstrap_secret [--recreate]~ :: Bootstrap secret but no
+  other steps
+
+Per namespace/app can be diff'd or applied via ~kubectl {diff, apply} -k
+namespaces/[<namespace>/[<appName>/]]~
