在Ubuntu环境下使用Docker容器,可以按照以下步骤进行:
sudo apt update sudo apt install apt-transport-https ca-certificates curl software-properties-common curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" sudo apt update sudo apt install docker-ce sudo systemctl start docker sudo systemctl enable docker sudo docker --version 或者运行一个简单的Docker容器来测试Docker是否正常工作:
sudo docker run hello-world docker pull hello-world docker run -itd --name my_container hello-world docker ps docker stop my_container docker rm my_container docker rmi hello-world sudo curl -L "https://github.com/docker/compose/releases/download/1.28.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose docker-compose.yml):version: '3.8' services: web: image: nginx:alpine ports: - "80:80" db: image: postgres:latest environment: POSTGRES_DB: mydatabase POSTGRES_USER: user POSTGRES_PASSWORD: password docker-compose up -d docker-compose ps docker-compose down 以上步骤涵盖了在Ubuntu环境下安装Docker、使用Docker容器以及使用Docker Compose的基本流程。
