Podman : Use Docker Compose

	To Install Docker Compose, it's easy to configure and run multiple containers as a Docker application.
[1]	Install Podman-docker, refer to here.
[2]	Install Docker Compose.

root@dlp:~#  curl -L https://github.com/docker/compose/releases/download/v2.35.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose root@dlp:~#  chmod 755 /usr/local/bin/docker-compose root@dlp:~#  /usr/local/bin/docker-compose --version Docker Compose version v2.35.1

[3]	For example, Configure an application that has Web and DB services with Docker Compose.

# start podman.socket root@dlp:~#  systemctl start podman.socket # define Web service container root@dlp:~#  vi Dockerfile FROM debian MAINTAINER ServerWorld <admin@srv.world> RUN apt-get update RUN apt-get -y install nginx RUN echo "Compose Test on Nginx" > /var/www/html/index.html EXPOSE 80 CMD ["/usr/sbin/nginx", "-g", "daemon off;"] # define application configuration root@dlp:~#  vi docker-compose.yml services: db: image: docker.io/library/mariadb volumes: - /var/lib/containers/disk01:/var/lib/mysql environment: MYSQL_ROOT_PASSWORD: password MYSQL_USER: debian MYSQL_PASSWORD: password MYSQL_DATABASE: debian_db user: 0:0 privileged: true ports: - "3306:3306" web: build: . ports: - "80:80" volumes: - /var/lib/containers/disk02:/usr/share/nginx/html privileged: true # build and run root@dlp:~#  /usr/local/bin/docker-compose up -d ..... ..... ✓ web Built ✓ Network root_default Created ✓ Container root-db-1 Started ✓ Container root-web-1 Started root@dlp:~#  podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 211a549dc2bd docker.io/moby/buildkit:buildx-stable-1 About a minute ago Up About a minute buildx_buildkit_default c822c61bd9a7 docker.io/library/root-web:latest /usr/sbin/nginx -...

[4]	Other basic operations of Docker Compose are follows.
