Docker-settings

For changing docker to use another path to save config and volumes follow the steps below:

Stop docker

systemctl stop docker.service docker.socket

Change settings

First create lib's for docker libraries

mkdir -p /mnt/docker/lib

Then edit docker service

vim /lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd -g /mnt/docker/lib -H fd:// --containerd=/run/containerd/containerd.sock

Restart docker

systemctl daemon-reload
systemctl start docker

Cloning project

cd /root
git clone https://github.com/mrunix1998/docker-registry.git

Quick Start

1 - Go to nginx folder :

cd /root/docker-registry/nginx/

• Go to certs file and run bash script to create needed certs for nginx and registry :

cd certs
bash create_certs.sh

Note : Write your domain name in both of common name when creating certs.

• Then got to the conf.d file and change registry.conf ==> (line 11, 12, 17)

• Finally, you can start up your nginx container:

bash setup.sh up

2 - Go to registry folder :

 cd /root/docker-registry/registry/

• Run create_reg_user.sh script file to create registry user :

bash create_reg_user.sh

• Finally, run start up script to run registry and registry ui container:

Note : Notice that on line 22 in registry.yml change registry admin password. Note : After runing registry and registry-ui, restart nginx again.

 bash setup.sh up

On client you should set below command in /etc/docker/daemon.json or update certificate to know your registry's CA.crt :

{
  "insecure-registries": [
    "registry.example.com:443"
  ]
}

systemctl daemon-reload
systemctl restart docker

or

• ssh CA.crt from registry vm and then run :

mkdir /usr/local/share/ca-certificates/docker-cert
cp CA.crt /usr/local/share/ca-certificates/docker-cert

systemctl restart docker

For login and taging and push and pull images in registry you should run following commands :

docker login registry.example.com:443

docker tag <someimage> registry.example.com:443/<someimage>:<tag>

docker push registry.example.com:443/<someimage>:<tag>

docker pull registry.example.com:443/<someimage>:<tag>

You should use registry api in ui with following url :
