Setup Docker service to use insecure(http) registry instead of https

May 17, 2021 Leave a Comment

By default docker use https to connect to docker registry. But there can be use cases to use insecure registry. Here are the steps to use insecure registry.

In ubuntu
edit the file /etc/default/docker and update DOCKER_OPTS e.g

DOCKER_OPTS='--insecure-registry 15.206.81.210:9000'

where 15.206.81.210 is ipaddress of registry and 9000 is your port on which registry is configured.

In Centos
Edit the file /etc/docker/daemon.json e.g.

$ vi /etc/docker/daemon.json

{
"insecure-registries" : ["15.206.81.210:9001"]
}

$ service docker restart

where 15.206.81.210 is ipaddress of registry and 9001 is your port on which registry is configured.
