Promtail 以二进制形式分布在 Docker 容器中，或者有一个 Helm chart 可以将其安装在 Kubernetes 集群中。

二进制

每个 Grafana Loki 版本都包含 Promtail 的二进制文件，可以在 发布页面上找到它作为发布资产的一部分。

码头工人

modify tag to most recent version

docker pull grafana/promtail:2.0.0

舵
确保已安装 Helm。请参阅安装 Helm。然后就可以将Grafana的chart仓库添加到Helm中了：

helm repo add grafana https://grafana.github.io/helm-charts
并且可以通过运行更新图表存储库：

helm repo update
最后，可以使用以下方式部署 Promtail：

$ helm upgrade –install promtail grafana/promtail –set “loki.serviceName=loki”

DaemonSet（推荐）
ADaemonSet将在 Kubernetes 集群中的每个节点上部署 Promtail。

DaemonSet 部署可以很好地收集集群内所有容器的日志。这是单租户模型的最佳解决方案。替换{YOUR_LOKI_ENDPOINT}为您的 Loki 端点。
