Docker Registry Manager is a golang written, beego driven, web interface for interacting with multiple docker registries (one to many).

Service	Master	Develop

Coverage

1. Support for docker distribution registry v2 (https and http)
2. Viewable image/tags stages, commands, and sizes.
3. Bulk deletes of tags
4. Registry activity logs
5. Comparison of registry images to public Dockerhub images

1. Authentication for users with admin/read only rights using TLS
2. Global search
3. List image shared layers
4. Event timeline

The below steps assume you have a docker registry currently running (with delete mode enabled (https://docs.docker.com/registry/configuration/). To add a registry to manage, add via the interface... or via the registries.yml file

Install compose (https://docs.docker.com/compose/install/), and then run the below commands

 git clone https://github.com/snagles/docker-registry-manager.git && cd docker-registry-manager
 vim registries.yml # add your registry
 vim docker-compose.yml # Edit application settings e.g log level, port
 docker-compose up -d
 firefox localhost:8080

• MANAGER_PORT: Port to run on inside the docker container
• MANAGER_REGISTRIES: Registries.yml file location inside the docker container
• MANAGER_LOG_LEVEL: Log level for logs (fatal, panic, error, warn, info, debug)
• MANAGER_ENABLE_HTTPS: true/false for using HTTPS. When using HTTPS the below options must be set
• MANAGER_KEY: key file location inside the docker container
• MANAGER_CERTIFICATE: Certificate location inside the docker container

With a working kubernetes cluster and helm installation, run the following:

 git clone https://github.com/snagles/docker-registry-manager.git && cd docker-registry-manager
 vim helm/values.yaml # configure with your cluster specifics and add registries
 helm install --name docker-registry-manager helm/

   git clone https://github.com/snagles/docker-registry-manager.git && cd docker-registry-manager
   vim registries.yml # add your registry
   cd app && go build . && ./app --port 8080 --log-level warn --registries "../registries.yml"
   firefox localhost:8080

• port, p: Port to run on
• registries, r: Registrys.yml file location
• log-level, l: Log level for logs (fatal, panic, error, warn, info, debug)
• enable-https, e: true/false for using HTTPS. When using HTTPS the below options must be set
• tls-key, k: key file location inside the docker container
• tls-certificate, cert: Certificate location inside the docker container

   vim registries.yml # add your registry
   docker run --detach --name docker-registry-manager -p 8080:8080 -e MANAGER_PORT=8080 -e MANAGER_REGISTRIES=/app/registries.yml -e MANAGER_LOG_LEVEL=warn docker-registry-manager
   firefox localhost:8080

• MANAGER_PORT: Port to run on inside the docker container
• MANAGER_REGISTRIES: Registries.yml file location inside the docker container
• MANAGER_LOG_LEVEL: Log level for logs (fatal, panic, error, warn, info, debug)
• MANAGER_ENABLE_HTTPS: true/false for using HTTPS. When using HTTPS the below options must be set
• MANAGER_KEY: key file location inside the docker container
• MANAGER_CERTIFICATE: Certificate location inside the docker container

registries:
  localRegistry:
    displayname: registry.example.com:5000
    url: http://localhost # Example https://localhost, http://remotehost.com
    port: 5000  # Example: 443, 8080, 5000
    username: exampleUser
    password: examplePassword
    refresh-rate: "5m" # Example: 60s, 5m, 1h
    skip-tls-validation: true # REQUIRED for self signed certificates
    dockerhub-integration: true # Optional - compares to dockerhub to determine if image up to date
