Error getting v2 registry: Get net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)"


Known Issue


Release : 10.4


1. sudo mkdir -p /etc/systemd/system/docker.service.d

2. create a file named /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:


Please replace with customer proxy URL. First line after [Service] is for HTTP proxy and second line is for HTTPS proxy. If customer has only one of them (for example HTTPS PROXY), then he can delete line with HTTP_PROXY.

4. Restart Docker

sudo systemctl daemon-reload
sudo systemctl restart docker

5. Verify that the configuration has been loaded and matches the changes you made, for example:

sudo systemctl show --property=Environment docker
Environment=HTTP_PROXY= HTTPS_PROXY= NO_PROXY=localhost,,,.corp

Please first follow above steps with customer, because I think that the problem is in fact, that the Docker doesn't use customer's proxy server pro communication with public registry.
