docker 注册表_设置docker注册表和docker regui

In this story, we will install Docker Registry on a VM and the cloud and we will add a Docker container to browser the registries from a web browser. From my side, I created an ECS instance on Alibaba Cloud. But we could do it everywhere. After creating the ECS instance, I got its public IP address (8.208.91.39) and I created a security group to authorize the following ports:

在这个故事中，我们将在虚拟机和云上安装Docker Registry，并将添加Docker容器从Web浏览器浏览注册表。 就我而言，我在阿里云上创建了ECS实例。 但是我们可以在任何地方做。 创建ECS实例后，我获得了其公用IP地址( 8.208.91.39 )，并创建了一个安全组来授权以下端口：

• 5000 for the Docker Registry,

  5000用于Docker Registry，

• 8086 for the Docker Registry UI.

  Docker Registry UI的8086 。

设置Docker和Docker Compose (Set up Docker and Docker Compose)

On the VM, if Docker and Docker Compose are not installed, install them:

在VM上，如果未安装Docker和Docker Compose，请安装它们：

• Docker:
  码头工人：

yum install -y yum-utilsyum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repoyum install -y docker-ce docker-ce-cli containerd.iosystemctl start docker

• Docker Compose:
  Docker撰写：

curl -L "https://github.com/docker/compose/releases/download/1.27.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-composechmod +x /usr/local/bin/docker-composeln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

I ran these commands as root.

我以root身份运行了这些命令。

Let’s verify that Docker and Docker Compose are well installed:

让我们验证Docker和Docker Compose的安装是否正确：

docker run hello-worlddocker-compose --version

设置Docker Registry和Docker Registry UI (Set up Docker Registry and Docker Registry UI)

Let’s install a Docker Registry from a Docker image.

让我们从Docker映像安装Docker注册表。

Create a docker_registry directory:

创建一个docker_registry目录：

mkdir docker_registrycd docker_registry

Download the image registry:2:

下载映像registry:2 ：

docker pull registry:2

The output is:

输出为：

2: Pulling from library/registrycbdbe7a5bc2a: Pull complete47112e65547d: Pull complete46bcb632e506: Pull completec1cc712bcecd: Pull complete3db6272dcbfa: Pull completeDigest: sha256:8be26f81ffea54106bae012c6f349df70f4d5e7e2ec01b143c46e2c03b9e551dStatus: Downloaded newer image for registry:2docker.io/library/registry:2

Create a directory to store the Docker images in /tmp/docker_registry:

创建一个目录以将Docker映像存储在/tmp/docker_registry ：

mkdir /tmp/docker_registry

Launch Docker Registry by exposing the ports from5000/tcp to 8888/tcp on the host:

通过在主机上公
