插件工作原理

Patch argocd-repo-server

挂载 ConfigMap/cmp-plugin
挂载 empty-dir custom-tools

initContainers

通过 curl github 下不动 - 建议做镜像或者自己镜像文件

下载 argocd-vault-plugin 到 custom-tools

curl -L https://github.com/argoproj-labs/argocd-vault-plugin/releases/download/v$(AVP_VERSION)/argocd-vault-plugin_$(AVP_VERSION)_linux_amd64 -o argocd-vault-plugin \
  && chmod +x argocd-vault-plugin \
  && mv argocd-vault-plugin /custom-tools/

ConfigMap/cmp-plugin 配置 argocd - 通过 argocd-vault-plugin generate 生成

avp-kustomize.yaml

ConfigManagementPlugin

# discover.find.command
find . -name kustomization.yaml
# generate.command
kustomize build . | argocd-vault-plugin generate -

avp-helm.yaml

find . -name 'Chart.yaml' && find . -name 'values.yaml'

helm template $ARGOCD_APP_NAME -n $ARGOCD_APP_NAMESPACE ${ARGOCD_ENV_HELM_ARGS} . | argocd-vault-plugin generate -

AVP_VERSION=1.15.0
curl -LO https://github.com/argoproj-labs/argocd-vault-plugin/releases/download/v${AVP_VERSION}/argocd-vault-plugin_${AVP_VERSION}_linux_amd64
