I am following the course on Docker, and on the lesson “The Sample Web Application” when I run the “docker-compose up”, I get the following error.
Cannot start service db: Ports are not available: listen tcp 0.0.0.0:27017: bind: address already in use.
Can someone help me. Thanks in advance.
I solved the problem by changing the port for now from 27017 to 27018 in two files.
And, also, solved the permission issue for sh file.
Made it executable.
chmod +x docker-entrypoint.sh
Additionally, if you are a mac user, change “./docker-entrypoint.sh” to “sh ./docker-entrypoint.sh” in docker-compose.yml
