pull image from remote registry - docker

Question

I have installed docker 1.11.2, I am trying to make one private registry for our office.

I followed this link to make private registry, I have successfully pull from localhost but I stuck trying to pull from remote machine.

Short Description of what I have done

Step1 :

docker run -d -p 5000:5000 --restart=always --name registry registry:2

step2:

[root@raj raj]# docker images
REPOSITORY          TAG                 IMAGE ID                   CREATED             SIZE
hello-world         latest              c54a2cc56cbb        11 days ago         1.848 kB
registry            2                   8ff6a4aae657        4 weeks ago         171.5 MB

step3: (for localhost)

[root@raj raj]# docker tag hello-world localhost:5000/hello-world

[root@raj raj]# docker push localhost:5000/hello-world
The push refers to a repository [localhost:5000/hello-world]
a02596fdd012: Pushed 
latest: digest: sha256:a18ed77532f6d6781500db650194e0f9396ba5f05f8b50d4046b294ae5f83aa4 size: 524

step4:

[root@raj raj]# docker pull localhost:5000/hello-world
Using default tag: latest
latest: Pulling from hello-world

Digest: sha256:a18ed77532f6d6781500db650194e0f9396ba5f05f8b50d4046b294ae5f83aa4
Status: Image is up to date for localhost:5000/hello-world:latest

It is working fine

I am trying to pull the image from private registry from remote machine so I have altered the step 3 like below

step3:

[root@raj raj]# docker tag hello-world 192.168.1.23:5000/hello-world

[root@raj raj]# docker push 192.168.1.23:5000/hello-world
The push refers to a repository [192.168.1.23:5000/hello-world]
Get https://192.168.1.23:5000/v1/_ping: tls: oversized record received with length 20527

but it throws error tls:oversized

I have some links related to this issue link1, link2 but it does not resolve my problem

I have some doubt about this link

1) I could not found any docker file in that location /etc/sysconfig/docker, /etc/default/docker for changing –insecure-registry

2) docker -d --insecure-registry 10.11.12.0:5000 (this command is not working it throws below error.

[root@raj raj]# docker -d --insecure-registry 192.168.1.23:5000
flag provided but not defined: -d
See 'docker –help'.

Please help to get pull request from remote machine to private registry.

Answer 1

Follow the sequence of docker command for making private registry

Server Side

docker daemon --insecure-registry server-ip:5000
docker run -d -p 5000:5000 --restart=always --name registry registry:2
docker tag hello-world server-ip:5000/hello-world
docker push server-ip:5000/hello-world

Client side

docker daemon --insecure-registry server-ip:5000
docker pull server-ip:5000/hello-world

Now you can pull/push from your remote repositories, for more detail of registry you can use this command docker inspect registry it will show where the images get store and more info.

Answer 2

Update docker config to add "--insecure-registry", usually the file is located in /etc/default/docker, if you use docker-machine the file is located in /var/lib/boot2docker/profile
