DockerfileのRUNとCMD、docker-compose.yaml内のマウントタイミング

例えば

docker-compose.yml
build: './test'
volumes:
  - ./:/var/www/html
test/Dockerfile
RUN chmod +x /var/www/html     # var/www/html not found
CMD chmod +x /var/www/html     # 思い通りに動く

docker-compose.yamlでマウントしたファイルに対して、Dockerfileで操作したいときは
RUNではなくCMDを使う。

順番は、RUNvolumesCMDだ。
