yku Leave a comment

眾所周知，Docker容器是IT世界中技術需求量很大。在 Docker Container協助下，開發人員和基礎設施管理員可以打包他們的應用程式及其依賴項目，並可以在一個computer將其deploy，換到另一個computer中一樣可行。

以下將介紹如何逐步在Rocky Linux 8(AlamLinux)上安裝Docker和Docker Compose。

Step 1 安裝所需套件及repository

 sudo yum install -y yum-utils
 sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

Step 2 安裝docker 及docker compose

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Step 3 啟動docker

sudo systemctl start docker

Step 4 測試一下

sudo docker run hello-world

設定啟動Linux自動啟動

sudo systemctl enable docker
