+# nix
+
+[nix](https://nixos.org/) is a tool that takes a unique approach to package
+management and system configuration.
+
+This setup is based on the [NixCon 2023 talk](https://www.youtube.com/watch?v=SEA1Qm8K4gY).
+
+## Set up the argo-cd installation for nix support
+
+This setup uses the stock `nixos/nix:latest` image without any modifications.
+That requires some changes in runtime, as nix cannot run as user 999 our of the
+box.
+
+Add the following bits to the values.yaml of your helm deployment:
+
+```yaml
+repoServer:
+  volumes:
+    - name: nix-cmp-config
+      configMap:
+        name: nix-cmp-config
+    - name: nix-cmp-tmp
+      emptyDir: {}
+    - name: nix-cmp-nix
+      emptyDir: {}
+    - name: nix-cmp-home
+      emptyDir: {}
+  initContainers:
+    - name: nix-bootstrap
+      # the init container copies the whole nix store and profiles into the
+      # temporary volume and makes sure the permissions are correct
+      command:
+        - "sh"
+        - "-c"
+        - "cp -a /nix/* /nixvol && chown -R 999 /nixvol/*"
+      image: nixos/nix:latest
+      # the image will always be updated at init step, so the one in the
+      # extraContainers must have the policy of Never to always be the same
+      # exact image.
+      imagePullPolicy: Always 
+      volumeMounts:
+        - mountPath: /nixvol
+          name: nix-cmp-nix
+  extraContainers:
+    - name: nix-cmp-plugin
+      command:
+        - /var/run/argocd/argocd-cmp-server
+      image: nixos/nix:latest
+      imagePullPolicy: Never
+      securityContext:
+        runAsNonRoot: true
+        runAsUser: 999
+      volumeMounts:
+        - mountPath: /var/run/argocd
+          name: var-files
+        - mountPath: /home/argocd/cmp-server/plugins
+          name: plugins
+        - mountPath: /home/argocd/cmp-server/config/plugin.yaml
+          subPath: plugin.yaml
+          name: nix-cmp-config
+        - mountPath: /etc/passwd
+          subPath: passwd
+          name: nix-cmp-config
+        - mountPath: /etc/nix/nix.conf
+          subPath: nix.conf
+          name: nix-cmp-config
+        - mountPath: /tmp
+          name: nix-cmp-tmp
+        - mountPath: /nix
+          name: nix-cmp-nix
+        - mountPath: /home/nix
