Add Insecure Registry to Docker

docker insecure-registry centos 7
docker pull --insecure-registry
docker insecure-registry windows
docker login insecure-registry command line
docker insecure-registry mac
docker multiple insecure registries
unknown flag: --insecure-registry
ubuntu 18.04 docker add insecure-registry

I have a docker 1.12 running on CentOS. I am trying to add insecure registry to it and things mentioned in documentation just don't work. The system uses systemd so I created a /etc/systemd/system/docker.service.d/50-insecure-registry.conf file.

$ cat /etc/systemd/system/docker.service.d/50-insecure-registry.conf
[Service]
Environment='DOCKER_OPTS=--insecure-registry="hostname.cloudapp.net:5000"'

After loading daemon and restarting docker service, systemd shows that the environment variable is there

$ sudo systemctl show docker | grep Env
Environment=DOCKER_OPTS=--insecure-registry="hostname.cloudapp.net:5000"

But when I run docker info I don't see that insecure registry added

$ docker info
........
Registry: https://index.docker.io/v1/
WARNING: bridge-nf-call-iptables is disabled
WARNING: bridge-nf-call-ip6tables is disabled
Insecure Registries:
    127.0.0.0/8

Pushing images to hostaneme.cloudapp.net fails with

Pushing application     (hostname.cloudapp.net:5000/application:latest)...
The push refers to a repository     [hostname.cloudapp.net:5000/mozart_application]
ERROR: Get https://hostname.cloudapp.net:5000/v1/_ping: http: server gave HTTP response to HTTPS client

Is there something that could be done ? Am I missing something ?

UPDATE

Resolved the issue by adding a file /etc/docker/daemon.json with following content

{
    "insecure-registries" : [ "hostname.cloudapp.net:5000" ]
}

And then restart docker

sudo systemctl daemon-reload
sudo systemctl restart docker

After that insecure registry hostname.cloudapp.net:500 works.

To add an insecure docker registry, add the file /etc/docker/daemon.json with the following content:

{
    "insecure-registries" : [ "hostname.cloudapp.net:5000" ]
}

and then restart docker.

Add Insecure Registry to Docker, 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  Use self-signed certificates. Generate your own certificate: $ mkdir -p certs $ openssl req \ -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \ -x509 -days 365 -out Use the result to start your registry with TLS enabled . Instruct every Docker daemon to trust that certificate. The way

The solution with the /etc/docker/daemon.json file didn't work for me on Ubuntu.

I was able to configure Docker insecure registries on Ubuntu by providing command line options to the Docker daemon in /etc/default/docker file, e.g.:

# /etc/default/docker    
DOCKER_OPTS="--insecure-registry=a.example.com --insecure-registry=b.example.com"

The same way can be used to configure custom directory for docker images and volumes storage, default DNS servers, etc..

Now, after the Docker daemon has restarted (after executing sudo service docker restart), running docker info will show:

Insecure Registries:
  a.example.com
  b.example.com
  127.0.0.0/8

For me the solution was to add the registry to here:

Add Insecure Registry to Docker, Hello, I wanted to ask if it is possible to add an insecure registry during a github action. I have to push a docker image to a registry and it's. By default, docker uses  https to connect to the docker registry. But there can be use cases to use an insecure registry, especially if you’re on a trusted network. This eliminates the need for a CA-signed certificate for internal use or to trust self-signed certificate in all docker nodes.

Comments
  • While someone beat you to it in this case (after giving you a generous grace period), this would've been an excellent case for a self-answer.
  • excellent! I had this error message while "oc cluster up" with Openshift javamonamour.org/2017/12/docker-insecure-registry.html and your fix solved it!
  • I know you explicitly asked for this in relation to CentOS in your question, but to anyone who lands here looking for an macOS solution like I did, it can be done through the GUI now, as mentioned in the answer on this question.
  • I believe that's the right solution on debian-likes. On Red Hat likes you want to add it to /etc/sysconfig/docker as one of the options, e.g. from an Openshift installation: OPTIONS='--insecure-registry=172.30.0.0/16 --others [...]' On Suse-likes I don't know.
  • On DigitalOcean, the 1 click Docker image still thinks use use DOCKER_OPTS versus the daemon.json file version. Thanks!
  • @erikbwork On Fedora 28 with Docker 1.13.1 from the default package repos, the approach with /etc/docker/daemon.json works fine.
  • cannot restart docker after creating this daemon.json, showing error: Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. @matt
