I'm hoping someone with experience in

问题 According to https://github.com/krallin/tini#using-tini, tini is built into docker, and can be used by passing the --init flag to docker run . In my case I'm using docker-compose and don't invoke docker run directly. How can I pass this flag? 回答1: If you are using version 2 of docker-compose , the configuration parameter is called init .
