Get container name inside the docker container

Docker-compose can easily launch multi-container with the config file (default: docker-compose.yml ). For example, we have the following files.

node
├── docker-compose.yml
└── get_name.sh

In docker-compose.yml

version: '2.3'
services:
    node:
      image: alpine:3.13
      volumes:
        - ./:/root:z
      entrypoint: /bin/sh
      command: /root/get_name.sh

In get_name.sh

echo "hello world"
