我正在使用容器化的 Vespa.ai DB，我想从主机执行以下命令：

  1. vespa 停止服务
  2. vespa 删除索引
  3. vespa 启动服务

vespa-stop-services && vespa-remove-index && vespa-start-services如果我在附加容器后从我的 shell执行以下操作，它工作正常。但是当我使用 docker exec 时它失败了。

我尝试了以下命令：

docker exec bash -c 'vespa-stop-services && vespa-remove-index && vespa-start-services'

docker exec bash -l 'vespa-stop-services && vespa-remove-index && vespa-start-services'

我成功执行这些命令的唯一方法是按顺序执行它们，我想避免这种情况：

docker exec bash -l 'vespa-stop-services'

docker exec bash -l 'vespa-remove-index'

docker exec bash -l 'vespa-start-services'

我究竟做错了什么？提前致谢！

从父主机系统运行时，您需要指定这些命令的位置

以下工作/应该工作：

docker exec vespa bash -c "/opt/vespa/bin/vespa-stop-services && /opt/vespa/bin/vespa-remove-index -force && /opt/vespa/bin/vespa-start-services"

注意 -force，它不会在删除数据之前要求确认，还要注意索引不是唯一的持久数据，配置状态仍然保留。

名为“vespa”的 docker 容器的示例运行：

docker exec vespa bash -c "/opt/vespa/bin/vespa-stop-services && /opt/vespa/bin/vespa-remove-index -force && /opt/vespa/bin/vespa-start-services"
Executing /opt/vespa/libexec/vespa/stop-vespa-base.sh
