## 启动及访问 ##

sudo docker-compose -f docker-compose-grafana-promtail-loki.yml -p grafana_promtail_loki up -d

当使用 `-p` 选项指定了项目名称后，在启动容器时，Docker Compose 会在容器名称前添加该项目名称的前缀。

例如，在你提供的命令中，使用了 `-p grafana_promtail_loki` 指定了项目名称为 “grafana\_promtail\_loki”。如果你在 `docker-compose.yml` 文件中定义了一个名为 `app` 的服务，那么在使用 `docker-compose up` 启动容器后，该容器的名称将会是 “grafana\_promtail\_loki\_app”。

通过添加项目名称的前缀，Docker Compose 可以确保在同一主机上运行多个项目时，每个项目内的容器名称是唯一的，避免了命名冲突。

请注意，项目名称前缀仅适用于容器的名称，不会影响容器内部的主机名或其他配置。
