Ansible 错误：在 prometheus-community 索引中找不到匹配 50.3.1 的图表“kube-prometheus-stack”

Question

我尝试安装

kube-prometheus-stack

版本为

50.3.1

这里是图表的链接

但是 Ansible 正在崩溃并抱怨

Error: chart "kube-prometheus-stack" matching 50.3.1 not found in prometheus-community index. (try 'helm repo update'): no chart version found for kube-prometheus-stack-50.3.1

我确实跑了

helm repo update

，但没有帮助。另外，如果我手动运行该命令，它就可以工作。

helm upgrade -i --reset-values --atomic --create-namespace prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --version 50.3.1 -f roles/shlomo/monitoring/files/values-prometheus-stack.yaml

有人可以帮我解决发生的事情吗？

组件名称

珍藏版

kubernetes.core 2.4.0

配置

CONFIG_FILE() = /code/infrastructure/ansible/ansible.cfg
DEFAULT_FILTER_PLUGIN_PATH(/code/infrastructure/ansible/ansible.cfg) = ['/code/infrastructure/ansible/plugins/>
DEFAULT_HOST_LIST(/code/infrastructure/ansible/ansible.cfg) = ['/code/infrastructure/ansible/inventories/sorte>

DEFAULT_VAULT_PASSWORD_FILE(/code/infrastructure/ansible/ansible.cfg) = /root/.vault_pass
HOST_KEY_CHECKING(/code/infrastructure/ansible/ansible.cfg) = False

操作系统/环境

在 Docker 上运行

Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:        11
Codename:       bullseye

重现步骤

- name: Add kube prometheus stack chart repo
  kubernetes.core.helm_repository:
    repo_name: prometheus-community
    repo_url: https://prometheus-community.github.io/helm-charts

- name: Install kube prometheus stack chart
  kubernetes.core.helm:
    atomic: true
    name: prometheus
    chart_ref: prometheus-community/kube-prometheus-stack
    chart_version: 50.3.1
    create_namespace: true
    release_namespace: monitoring
    # values: "{{ lookup('file', 'files/values-prometheus-stack.yaml') | from_yaml }}" # i includeded this for completnes but you can ignore this

预期结果

helm 应该已经安装了指定版本的 kube-prometheus-stack 图表

实际结果

Ansible 未能安装图表

添加

update_repo_cache: true

解决问题。

这是它的样子

- name: Install kube prometheus stack chart
  kubernetes.core.helm:
    atomic: true
    name: prometheus
    chart_ref: prometheus-community/kube-prometheus-stack
    chart_version: 50.3.1
    update_repo_cache: true # <--------------------------This is the solution
    create_namespace: true
    release_namespace: monitoring
    values: "{{ lookup('file', 'files/values-prometheus-stack.yaml') | from_yaml }}" # i includeded this for completnes but you can ignore this
