Question

我为在Oracle VM Virtualbox上运行的CentOS 7在PuTTY上创建了SSH连接。在PuTTy上，我已经安装了Docker，然后安装了Docker Compose，它们已经启动并正在运行。但是，当我尝试使用以下命令下载在https://hub.docker.com/r/jenkins/jenkins/上找到的Jenkins Docker映像时遇到错误：

[jenkins@localhost ~]$ docker pull jenkins/jenkins
Using default tag: latest
Error response from daemon: Get https://registry-1.docker.io/v2/jenkins/jenkins/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Ajenkins%2Fjenkins%3Apull&service=registry.docker.io: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

也尝试过：

[jenkins@localhost ~]$  docker pull jenkins/jenkins:lts
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

我的互联网连接正常。有导致解决此问题的线索吗？谢谢。

Answer 1

我相信您尚未在终端上登录到您的Docker Hub帐户。使用命令def getPredictions(df, model, granularity='M1'): dfPredictions = pd.DataFrame() t = datetime.now(timezone.utc).strftime("%Y-%m-%d %H:%M:%S") try: df = generate_features(df) #generate a signal prediction = int(model.predict(x)[-1]) # Return prediction return prediction except: print(t, granularity, "Error Occured") raise登录。

然后尝试pull命令。

Answer 2

尝试先注销，然后使用用户名而不是电子邮件登录。
