docker-compose up問題

docker-compose up問題

> docker-compose up

Pulling PostgreSQL (postgre:latest)...ERROR: pull access denied for postgre, repository does not exist or may require 'docker login'

可能image名稱有誤，或沒登入docker hub

> docker-compose up

ERROR: for app  Cannot create container for service app: b'Conflict. The container name "/app" is already in use by container "bdf09cf31fe5f808c4493915ac9f33886fa460659473a7fdc071cd40a0d2e101". You have to remove (or rename) that container to be able to reuse that name.'

docker rm bdf09cf31fe5f808c4493915ac9f33886fa460659473a7fdc071cd40a0d2e101

重新build image並執行container

>docker-compose build && docker-compose up
