docker compose

安装compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version

docker-compose.yml模板

docker-compose在使用时，一般将微服务jar包、微服务的Dockerfile文件和docker-compose.yml放在同一目录下。将先jar包打包成新镜像，然后运行docker-compose up -d启动所有服务。
