For more versions, refer to https://github.com/docker/compose/releases Judge whether the installation is successful or not. If you want the Docker Compose container to start automatically, You need to create a startup script. Create a docker compose start.sh script. The script content is docker compose - f/export/docker/docker compose nginx. yml up - d-f/export/docker/docker compose nginx. yml is to specify the configuration file of docker compose.
