# Nexus Repository Setting

## Docker Proxy

1. 建立 Docker Proxy Repository

- 每個 Repository 都要設定 HTTPS Port 且不能重複。
- Remote storage 設定為: https://registry-1.docker.io/
- Docker Index 設定為: Use Docker Hub


2. Docker Client 設定
- 使用 Nexus Account 登入 Docker Registry

    root@gorilla-System-Product-Name:/home/gorilla# docker login 192.168.0.111:18443
    Authenticating with existing credentials...
    WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
    Configure a credential helper to remove this warning. See
    https://docs.docker.com/engine/reference/commandline/login/#credentials-store

    Login Succeeded
    root@gorilla-System-Product-Name:/home/gorilla#

- 修改 daemon.json

    vim /etc/docker/daemon.json

    {
        "insecure-registries": [
                "192.168.0.111:18443"
        ],
        "registry-mirrors": ["https://192.168.0.111:18443"]
    }

- Pull docker image from nexus docker proxy:

    root@gorilla-System-Product-Name:/home/gorilla# docker pull 192.168.0.111:18443/ubuntu:22.04
    22.04: Pulling from ubuntu
