ubuntu - Error with docker login: no such host -


after starting private docker registry registry docker image, doing login registry

docker login http://docker.mydomain.com:5000

causes following error after typing in name, password , email:

fata[0007] error response daemon: v1 ping attempt failed error: https://docker.mydomain.com:5000/v1/_ping: dial tcp: lookup docker.mydomain.com: no such host. if private registry supports http or https unknown ca certificate, please add `--insecure-registry docker.mydomain.com:5000` daemon's arguments. in case of https, if have access registry's ca certificate, no need flag; place ca certificate @ /etc/docker/certs.d/docker.mydomain.com:5000/ca.crt

trying insecure login not work too:

docker login --insecure-registry http://docker.mydomain.com:5000

any suggestions? thanks!

you misunderstanding --insecure-registry flag - daemon not client. stated in error message:

please add --insecure-registry docker.mydomain.com:5000 daemon's arguments.

you need add daemon , restart if want use insecure private registry. otherwise, put behind web server uses https , proxy it.
