# Blue Green
|
|
||||||
|
|
||||||
The blue green strategy is not supported by built-in Kubernetes Deployment but available via third-party Kubernetes controller.
|
|
||||||
This example demonstrates how to implement blue-green deployment via [Argo Rollouts](https://github.com/argoproj/argo-rollouts):
|
|
||||||
|
|
||||||
1. Install Argo Rollouts controller: https://github.com/argoproj/argo-rollouts#installation
|
|
||||||
2. Create a sample application and sync it.
|
|
||||||
|
|
||||||
```
|
|
||||||
argocd app create --name blue-green --repo https://github.com/argoproj/argocd-example-apps --dest-server https://kubernetes.default.svc --dest-namespace default --path blue-green && argocd app sync blue-green
|
|
||||||
```
|
|
||||||
|
|
||||||
Once the application is synced you can access it using `blue-green-helm-guestbook` service.
|
|
||||||
|
|
||||||
3. Change image version parameter to trigger blue-green deployment process:
|
|
||||||
|
|
||||||
```
|
|
||||||
argocd app set blue-green -p image.tag=0.2 && argocd app sync blue-green
|
|
||||||
```
|
|
||||||
|
|
||||||
Now application runs `ks-guestbook-demo:0.1` and `ks-guestbook-demo:0.2` images simultaneously.
|
|
||||||
The `ks-guestbook-demo:0.2` is still considered `blue` available only via preview service `blue-green-helm-guestbook-preview`.
|
|
||||||
|
|
||||||
4. Promote `ks-guestbook-demo:0.2` to `green` by patching `Rollout` resource:
|
|
||||||
|
|
||||||
```
|
|
||||||
argocd app patch-resource blue-green --kind Rollout --resource-name blue-green-helm-guestbook --patch '{ "status": { "verifyingPreview": false } }' --patch-type 'application/merge-patch+json'
|
|
||||||
```
|
|
||||||
|
|
||||||
This promotes `ks-guestbook-demo:0.2` to `green` status and `Rollout` deletes old replica which runs `ks-guestbook-demo:0.1`.

# A chart can be either an 'application' or a 'library' chart.

# to be deployed.
|
|

#
|
|
||||||
# Library charts provide useful utilities or functions for the chart developer. They're included as

# a dependency of application charts to inject those utilities and functions into the rendering
|
|
||||||
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
|
|
||||||
type: application
|

|

||||||
# This is the chart version. This version number should be incremented each time you make changes

# Helm Dependencies
|
|
||||||
|
|
||||||
This example application demonstrates how an OTS (off-the-shelf) helm chart can be retrieved and
|
|
||||||
pinned to a specific helm sem version from an upstream helm repository, and customized using a custom
|
|
||||||
values.yaml in the private git repository.
|
|
||||||
|
|
||||||
In this example, the wordpress application is pulled from the stable helm repo, and pinned to v5.0.2:
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
dependencies:
|
|
||||||
- name: wordpress
|
|
||||||
version: 5.0.2
|
|
||||||
repository: https://charts.helm.sh/stable
|
|
||||||
```
|
|
||||||
|
|
||||||
A custom values.yaml is used to customize the parameters of the wordpress helm chart:
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
wordpress:
|
|
||||||
wordpressPassword: foo
|
|
||||||
mariadb:
|
|
||||||
db:
|
|
||||||
password: bar
|
|
||||||
rootUser:
|
|
||||||
password: baz
|
|
||||||
```
|
|
||||||
|
|
||||||
### Subchart Note
|
|
||||||
|
|
||||||
The wordpress chart referenced in this example contains a subchart for mariadb as specified in the requirements.yaml file of the wordpress chart:
|
|
||||||
```yaml
|
|
||||||
- name: mariadb
|
|
||||||
version: 5.x.x
|
|
||||||
repository: https://charts.helm.sh/stable
|
|
||||||
condition: mariadb.enabled
|
|
||||||
tags:
|
|
||||||
- wordpress-database
|
|
||||||
```
|
|
||||||
|
|
||||||
In order to disable this chart, you must set the value to false for both `mariadb.enabled` and `wordpress.mariadb.enabled`. The first is used by the mariadb subchart condition field, the second is used by the wordpress chart deployment template. An example demonstration is available in the values-nomaria.yaml file:
|
|
||||||
```yaml
|
|
||||||
mariadb:
|
|
||||||
enabled: false
|
|
||||||
|
|
||||||

# Kasane
|
|
||||||
|
|
||||||
[Kasane](https://github.com/google/kasane) is a layering tool for Kubernetes which utilises Jsonnet for deep object modification and patching.
|
|
||||||
|
|
||||||
Use following steps to try the application:
|
|
||||||
|
|
||||||
* Follow instructions from [custom_tools.md](https://github.com/argoproj/argo-cd/blob/master/docs/operator-manual/custom_tools.md) to make sure `kasane` binary is available in `argocd-repo-server` pod.
|
|
||||||
* Register `kasane` plugin `argocd-cm` ConfigMap:
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
apiVersion: v1
|
|
||||||
data:
|
|
||||||
configManagementPlugins: |
|
|
||||||
- name: kasane
|
|
||||||
init:
|
|
||||||
command: [kasane, update]
|
|
||||||
generate:
|
|
||||||
command: [kasane, show]
|
|
||||||
```
|
|
||||||
* Create application using `kasane` as a config management plugin name.
|
|
||||||
|
|
||||||
```
|
|
||||||
argocd app create kasane \
|
|
||||||
--config-management-plugin kasane \
|
|
||||||
--repo https://github.com/argoproj/argocd-example-apps \

# A chart can be either an 'application' or a 'library' chart.

# Library charts provide useful utilities or functions for the chart developer. They're included as

# Helm + Kustomize
|
|
||||||
|
|
||||||
Sometimes Helm chart don't have all required parameters and additional customization is required. This example application demonstrates how to combine Helm and Kustomize and use it
|
|
||||||
as a config management plugin in Argo CD.
|
|
||||||
|
|
||||||
Use following steps to try the application:
|
|
||||||
|
|
||||||
* configure `kustomized-helm` tool in `argocd-cm` ConfigMap:
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
configManagementPlugins: |
|
|
||||||
- name: kustomized-helm
|
|
||||||
init:
|
|
||||||
command: ["/bin/sh", "-c"]
|
|
||||||
args: ["helm dependency build"]
|
|
||||||
generate:
|
|
||||||
command: ["/bin/sh", "-c"]
|
|
||||||
args: ["helm template . --name-template $ARGOCD_APP_NAME --namespace $ARGOCD_APP_NAMESPACE --kube-version $KUBE_VERSION > all.yaml && kustomize build"]
|
|
||||||
```
|
|
||||||
|
|
||||||
Notes:
|
|
||||||
- `$ARGOCD_APP_NAME`, `$ARGOCD_APP_NAMESPACE` and `$KUBE_VERSION` are environment variables that exists in the context of the plugin.
|
|
||||||
- setting `--kube-version` is important as helm template can mock up data which may not match the actual cluster version.
|
|
||||||
|
|
||||||
* create application using `kustomized-helm` as a config management plugin name:
|
|
||||||
|
|
||||||
|
|
||||||
```
|
|
||||||
argocd app create kustomized-helm \
|
|
||||||
--config-management-plugin kustomized-helm \
|
|
||||||
--repo https://github.com/argoproj/argocd-example-apps \

# 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

|

# the image will always be updated at init step, so the one in the
