Question

我正在尝试使用Docker API检索容器日志。

打开Docker状态的API文档以获取容器日志；应该使用的语法是；

/ containers / {id} / logs

根据文档，可能存在三种响应状态； 200 ， 404 和 500 。

您可以在下面查看文档的一部分；

responses:
        200:
          description: |
                  logs returned as a stream in response body.
                  For the stream format, [see the documentation for the attach endpoint](#operation/ContainerAttach).
                  Note that unlike the attach endpoint, the logs endpoint does not upgrade the connection and does not
                  set Content-Type.
          schema:
            type: "string"
            format: "binary"
        404:
          description: "no such container"
          schema:
            $ref: "#/definitions/ErrorResponse"
          examples:
            application/json:
              message: "No such container: c2ada9df5af8"
        500:
          description: "server error"
          schema:
            $ref: "#/definitions/ErrorResponse"

对我来说有趣的部分是，当我打电话时，我收到400错误，而该错误在文档中不存在。响应消息就像;

{
    "message": "Bad parameters: you must choose at least one stream"
}

如何使用Docker API获取容器日志？

Answer 1

通过发送stdout或stderr查询参数来指定从何处返回日志。示例：

curl --unix-socket /var/run/docker.sock http://localhost/containers/containerId/logs?stdout=true
