Step 4: add users to dockeroot group. Initially it is easier to do via vi

 usermod -G dockerroot hussaif1
dockerroot:x:979:bezroun,hussaif1,sanchers,jablonke,wangs90,saklotks

Change ownership of the docker daemon socket

Edit (or create) /etc/docker/daemon.json

1

2

3

4

{

    "live-restore": true,

    "group": "dockerroot"

}

And then restart the docker daemon

1

systemctl restart docker

 

Step 5 enable docler.service

root@lustwzib33:/root # systemctl start docker.service
root@lustwzib33:/root # systemctl enable docker.service

Step 5: Setup PROXY

Restart docker after modification proxy variables via /etc/sysconfig/docker file
HTTP_PROXY=http://USERNAME:[email protected]:8080/
HTTPS_PROXY=https://USERNAME:[email protected]:8080/
NO_PROXY= hostname.example.com,172.30.123.45
  • Without authentication
HTTP_PROXY=http://10.0.1.1:8080/
HTTPS_PROXY=10.0.0.1:8080/
NO_PROXY= hostname.example.com,172.30.123.45

 

 

Enable and start docker-distribution.service

systemctl enable docker-distribution.service
Created symlink from /etc/systemd/system/multi-user.target.wants/docker-distribution.service to /usr/lib/systemd/system/docker-distribution.service.
systemctl start docker-distribution.service

Test the registry

root@lustwzib33:/root # docker pull registry.access.redhat.com/rhel

access.redhat.com

As of RHEL 7.3.5, the registry.access.redhat.com/rhel7-init container image is available, and it is pre-configured to run systemd properly.
 

Environment

  • Red Hat Enterprise Linux 7

Issue

  • I would like to setup and install a docker registry, can this be done?

Resolution

  1. Install the Docker Registry
    Raw 
    # yum install docker-distribution
  2. Start the Docker Registry Service
    Raw 
    # systemctl start docker-distribution.service
    • You may want to have this start by default on boot, if so make sure you enable the service on.
    Raw 
    # systemctl enable docker-distribution.service

Interacting and using your private registry

Getting an image from a registry

  1. Pull an image from the Public Repository or use registry.access.redhat.com to get images directly from Red Hat.
    Raw 
    docker pull registry.access.redhat.com/rhel
    • You can also pull from your private registry (after images have been uploaded by specifying the registry location at the end of the pull command):
    Raw 
    docker pull myregistry.example.com:5000/rhel7
  2. Then, find the image id that corresponds to the fedora repository, and pull the latest tag'ed image.
    Raw 
    docker images | grep rhel | grep latest
registry.access.redhat.com/rhel                   latest              db7a70a0414e        3 hours ago         195.9 MB

Pushing an Image to a registry

  1. Create a tag for this image and point it at your private registry
    Raw 
    docker tag db7a70a0414e myregistry.example.com:5000/rhel7
  2. Push the image to the new registry to store it in its new home location.
    Raw 
    docker push myregistry.example.com:5000/rhel7

Listing images in a private docker registry

Diagnoiswtics

Diagnostic Steps

From the output of the docker pull that gave the forbidden error below, you can attempt to access the data the GET operation is running against using the curl command.

Raw 
# docker --log-level=debug pull registry.access.redhat.com/openshift3/metrics-hawkular-metrics:3.5.0 | tee dockerpull.out
Trying to pull repository registry.access.redhat.com/openshift3/metrics-hawkular-metrics ...
Get https://registry.redhat.io/containers/content/dist/rhel/server/7/7Server/x86_64/ose/3/containers/registry/openshift3/metrics-hawkular-metrics/manifests/3.5.0: Forbidden

# curl -vv https://registry.redhat.io/containers/content/dist/rhel/server/7/7Server/x86_64/ose/3/containers/registry/openshift3/metrics-hawkular-metrics/manifests/3.5.0

[Jan 27, 2019] If you are using the Docker package supplied by Red Hat / CentOS, the dockerroot group is automatically added to the system. You will need to edit (or create) /etc/docker/daemon.json to include the following: group : dockerroot

Highly recommended!
Jan 27, 2019 | rancher.com

If you are using the Docker Docker package supplied by Red Hat / CentOS, the package name is docker . You can check the installed package by executing:

rpm -q docker

If you are using the Docker package supplied by Red Hat / CentOS, the dockerroot group is automatically added to the system. You will need to edit (or create) /etc/docker/daemon.json to include the following:

{
    "group": "dockerroot"
}

Restart Docker after editing or creating the file. After restarting Docker, you can check the group permission of the Docker socket ( /var/run/docker.sock ), which should show dockerroot as group:

srw-rw----. 1 root dockerroot 0 Jul  4 09:57 /var/run/docker.sock

Add the SSH user you want to use to this group, this can't be the root user.

usermod -aG dockerroot <user_name>

To verify that the user is correctly configured, log out of the node and login with your SSH user, and execute docker ps :

ssh <user_name>@node
$ docker ps
CONTAINER

[Jan 26, 2019] You need to add user to dockerroot group and create daemon.json file to be able to use docker from a regular user account after Docker installation from Red Hat executables by Aslan Brooke

Highly recommended!
It is better to stop docker and start it after change of daemon.json. Restart does not always work as intended and socket can remain owned incorrectly.
Oct 15, 2018 | blog.aslanbrooke.com

Originally from Run Docker Without Sudo – Aslan Brooke's Blog

Update the /etc/docker/daemon.json as follow (will require root priveleges): 
{
"live-restore": true,
"group": "dockerroot"
}

Add user (replace ) to "dockerroot" group using the below command and then restart the docker service. 

usermod -aG dockerroot <user name> 
restart docker service
