我在Node.js应用程序中使用Dockerode触发了一些Docker容器。在某些情况下，In会触发错误：Error [ERR_STREAM_WRITE_AFTER_END]: write after end (参见下面的日志)。我有什么地方做错了吗？

下面是Docker的运行代码：

// Create custom resolver to test data source
const triggerTestDataSourceContainer = () => {
    return async (resolve, source, args, context, resolveInfo) => {
        // [...]

        // Instantiate Docker
        var Docker = require("dockerode");
        var docker = new Docker({ socketPath: "/var/run/docker.sock" });

        // Run Docker container
        docker.run(
            "mobydq-scripts",
            ["python", "run.py", authorization, "test_data_source", dataSourceId.toString()],
            [process.stdout, process.stderr],
            { name: "mobydq-test-data-source-" + dataSourceId, Tty: false, HostConfig: { AutoRemove: true, NetworkMode: "mobydq_network" } },
            function(err, data, container) {
                // Do nothing
            }
        );

        return result;
    };
};

下面是错误：

mobydq-graphql | events.js:180
mobydq-graphql |       throw er; // Unhandled 'error' event
mobydq-graphql |       ^
mobydq-graphql |

关于docker.run()方法的Dockerode文档不是很清楚，特别是create_options和start_options的语法几乎没有文档。https://github.com/apocas/dockerode#equivalent-of-docker-run-in-dockerode

我想我在[process.stdout, process.stderr]和Tty: false argument上做错了什么。似乎下面的更改解决了这个问题。

const triggerTestDataSourceContainer = () => {
    return async (resolve, source, args, context, resolveInfo) => {
        // [...]

        // Instantiate Docker
        var Docker = require("dockerode");
        var docker = new Docker({ socketPath: "/var/run/docker.sock" });

        // Run Docker container
        docker.run(
            "mobydq-scripts",
            ["python", "run.py", authorization, "test_data_source", dataSourceId.toString()],
            process.stdout,
            { name: "mobydq-test-data-source-" + dataSourceId, HostConfig: { AutoRemove: true, NetworkMode: "mobydq_network" } }, // Start options
            function(err, data, container) {
                // Do nothing
            }
        );

        return result;
    };
};
