安装插件方式来运行grafana-image-renderer

安装可以使用命令：

grafana-cli plugins install grafana-image-renderer

如果不能正常访问网络，或者下载速度太慢，可以使用离线包：到这里https://grafana.com/grafana/plugins/grafana-image-renderer/?tab=installation下载离线包，然后放到 plugins 文件夹下。需要注意下 plugins 文件夹的位置，可能使用命令安装的路径和真实的 plugins 目录不一致。

如果插件启动失败，报错：可以检查下 plugins/grafana-image-renderer/chrome-headless-shell/linux-136.0.7101.0/chrome-headless-shell-linux64 这个程序能否正常运行，如果报错

需要安装 apt install -y libasound2t64

kubernetes 部署配置

k8s 运行的时候，需要配置 root_url 被这个坑了很久，完整的配置文件如下：

  ldap.toml: |
    [[servers]]
    host = "1.1.1.1"
    port = 389
    use_ssl = false
    start_tls = false
    ssl_skip_verify = false
    bind_dn = "cn=admin,dc=example,dc=com"
    bind_password = "example"
    search_filter = "(uid=%s)"
    search_base_dns = ["dc=example,dc=com"]
    [servers.attributes]
    member_of = "memberOf"
    email =  "uid"
    name = "cn"
    username = "uid"
