命令在 docker 容器内工作，但因 docker exec 而失败

Question

我正在使用容器化 Vespa.ai 数据库，我想从主机执行以下命令：

vespa-停止服务
vespa-remove-index
vespa-start-services

如果我在附加容器后从我的 shell 执行以下 vespa-stop-services && vespa-remove-index && vespa-start-services，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'

我做错了什么？提前致谢！

Answer 1

从父主机系统运行ning 时需要指定这些命令的位置

以下 works/should 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，在删除数据之前不会要求确认，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"

Command works inside a docker container but fails with docker exec
