我在私有云主机上启动 docker 并收到下一个错误

sudo docker run hello-world
docker: Error response from daemon: OCI runtime create failed: /var/lib/docker/overlay2/83d55d497417883ea85b63ebe3138e5f5dbc2b3c8b2db663c1a007e7af1757f1/merged 
is not an absolute path or is a symlink: unknown.
ERRO[0000] error waiting for container: context canceled

我显示下一个

ll /var/lib/docker/overlay2                             
lrwxrwxrwx 1 root root 20 Jun 19 15:32 /var/lib/docker/overlay2 -> /dev/docker-overlay2/

有什么办法可以解决吗？

我在Ubuntu 14.04上安装了Gitlab。无法续订我们的加密证书。我已将Ubuntu升级到16.04，然后进行apt-get update和&& apt-get upgrade升级，但似乎它没有将ACME客户端升级到v2，这使我可以更新证书。如何更新证书？

gitlab-cli renew-le-certs 

结果是：

letsencrypt_certificate[elenx.net] (letsencrypt::http_authorization
line 3) had an error: Acme::Client::Error::Unauthorized:
acme_certificate[staging]
(/opt/gitlab/embedded/cookbooks/cache/cookbooks/letsencrypt/resources/certificate.rb
line 20) had an error: Acme::Client::Error::Unauthorized: Account
creation on ACMEv1 is disabled. Please upgrade your ACME client to a
version that supports ACMEv2 / RFC 8555. See
https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430
for details.

我找到了下一个例子

def prepare_retry_requester(retries: int = 5, forcelist: List = (503,)) -> requests.Session:
    requester = requests.Session()
    retry = urllib3.Retry(total=retries, backoff_factor=1, status_forcelist=forcelist)
    for protocol in 'http://', 'https://':
        requester.mount(protocol, requests.adapters.HTTPAdapter(max_retries=retry))
    return requester


with prepare_retry_requester(forcelist=[502, 503, 413]) as requester:
    response = requester.post(url, data=serialized)

但如果我出现502一段时间错误（服务器重新启动 10 秒），它仍然会失败。

升级到 pip-19.3.1 后

 pip-compile requirements.in

    return getattr(imported, package)
AttributeError: module 'pip._internal.download' has no attribute 'is_file_url'

我有下一个错误日志

对原因以及如何解决有什么想法吗？

如何在 pytdantic 浮点验证中过滤掉 NaN？

我有两个任务，我需要调用两个不同的 API 来发送短信和电子邮件。

视图.py

def ...:
    ...
    send_payment_failed_sms.delay(payment_log.id, 1)
    task_send_booking_failed_email(payment_log.id, 1)  

但是我总是在发送短信的任务中遇到以下错误，但发送电子邮件的任务工作正常：

我有

重新部署堆栈时

docker stack deploy -c docker-compose.yml --with-registry-auth monitoring

我想用发送的内容创建LISTE/NOTIFY管道。trigger_functionNOTIFY

在我的中NOTIFY，我想获取表中id任何行的消息。create/delete/update

我怎样才能写这样的通知trigger_function？

到目前为止我有下一次迁移吗？女巫创建没有行的触发器id

CREATE OR REPLACE FUNCTION notify_my_table_update() RETURNS TRIGGER AS $$
    BEGIN
    PERFORM pg_notify('my_table_update','');
    RETURN NULL;
    END;
$$ LANGUAGE plpgsql;

DROP TRIGGER IF EXISTS trigger_my_table_update ON my_table;
CREATE TRIGGER trigger_my_table_update
  AFTER UPDATE OR DELETE OR INSERT OR TRUNCATE
  ON my_table
  EXECUTE PROCEDURE notify_my_table_update();
