Additonal Configurations and Information:

Docker Hub Proxy

To set up a proxy to Docker Hub:

For the blob storage

• Click the config (gear) icon.
• Navigate to 'Blob Stores'.
• Create a new Blob Store of type File.
  • You can name it whatever you like, but a good choice is docker-hub.
• Click 'Create Blob Store'.

For the Security Realm

• Click Security > Realms
• Add the 'Docker Bearer Token Realm'
• Click 'Save'

For the repo itself

• Click 'Repositories'
• Click 'Create Repository' and select 'docker (proxy)'
• Give it some name (docker-hub-proxy)
• Check 'HTTP' and give it a valid port (8082)
• Check 'Allow anonymous docker pull'
• Under Proxy > Remote Storage, enter this url: https://registry-1.docker.io
• Under Docker Index, select 'Use Docker Hub'
• Under Storage > Blob Store, select the blob store you created earlier (docker-hub)
• Click 'Create Repository'

Docker configuration

For Docker Desktop (Windows or macOS), open your Docker Preferences, and select 'Docker Engine'.

Add this sections into the json file /etc/docker/daemon.json:

{
  "insecure-registries": ["IP_ADDRESS:8082"],
  "registry-mirrors": ["http://IP_ADDRESS:8082"]
}

{
  "registry-mirrors": ["https://docker-proxy.domain.net"]
}

Apply & Restart

sudo systemctl restart docker && sudo systemctl daemon-reload 

Pulling Through the Proxy

You can now pull images via your repository. If the image you want is not in your local repo, it'll be pulled from docker hub and cached into your repo for the default amount of time (24 hours) before being re-checked.

An example pull:

docker pull IP_ADDRESS:8082/ubuntu

Private Docker Repository

For the blob storage

• Click the config (gear) icon.
• Navigate to 'Blob Stores'.
• Create a new Blob Store of type File.
  • You can name it whatever you like, but a good choice is docker-private.
• Click 'Create Blob Store'.

For the repo itself

• Click 'Repositories'
• Click 'Create Repository' and select 'docker (hosted)'
• Give it some name (docker-private)
• Check 'HTTP' and give it a valid port (8083)
• Under Docker Index, select 'Use Docker Hub'
• Under Storage > Blob Store, select the blob store you created earlier (docker-private)
• Click 'Create Repository'

Docker Config

Make sure you add the new url and port to the insecure-registries section of the docker config.

Eg:

  "insecure-registries": [
    "IP_ADDRESS:8082",
    "IP_ADDRESS:8083"
  ],

Docker Login

To connect to the repository, you will need to login using the docker cli:

docker login IP_ADDRESS:8083

You can then provide user credentials (eg. - the admin user will work).

Tagging private images

When you build a docker impage you'd like to push to the private registry, be sure to prefix the image name with the registry url.

Example:

docker build -t IP_ADDRESS:8083/myimage:latest .

Once it has been built, you can push it to the registry:

docker push IP_ADDRESS:8083/myimage:latest

for composer .json

update composer.json file in your project root directory and add the following lines in the:

"repositories": [
	{
	  "type": "composer",
	  "url": "https://composer-proxy.youdromin.com/repository/composer-proxy/"
	},
	{
	  "packagist.org": false
	}
]

for npm and yarn:

in nexus side use This Link

for client side use this link

npm config --location=project set registry https://registry.npmmirror.com
npm config --location=global set registry https://registry.npmmirror.com
or
npm config --location=project set registry http://your-nexus-ip:8081/repository/npm-proxy/

if using nginx-proxy-manager :

# set a proxy domain https://nexus.your-domain.com
# path to http schema and ip then port 8081
# add these codes to advanced tab:

rewrite ^(.*)$ /repository/npm-proxy/$1;
if ($request_uri ~ ^/*$|^/[^/.]+$) {
	return 404; 
}
