php - Files changes not reflected in Docker image after rebuild -
i'm trying set 2 docker images php web application (php-fcm) reversed proxied nginx. ideally files of web application copied php-fcm based image , exposed volume. way both containers (web , app) can access files nginx serving static files , php-fcm interpreting php files.
docker-compose.yml
version: '2' services: web: image: nginx:latest depends_on: - app volumes: - ./site.conf:/etc/nginx/conf.d/default.conf volumes_from: - app links: - app app: build: . volumes: - /app dockerfile:
from php:fpm copy . /app workdir /app the above setup works expected. however, when make change files , do
compose --build the new files not picked in resulting images. despite following message indicating image indeed being rebuilt:
building app step 1 : php:fpm ---> cb4faea80358 step 2 : copy . /app ---> using cache ---> 660ab4731bec step 3 : workdir /app ---> using cache ---> d5b2e4fa97f2 built d5b2e4fa97f2 only removing old images trick.
any idea cause this?
$ docker --version docker version 1.11.2, build b9f10c9 $ docker-compose --version docker-compose version 1.7.1, build 0a9ab35
the 'volumes_from' option mounts volumes 1 container another. important word there container, not image. when rebuild image, previous container still running. if stop , restart container, or stop it, other containers still using old mount points. if stop, remove old app container, , start new one, old volume mounts still persist deleted container.
the better way solve in situation switch named volumes , setup utility container update volume.
version: '2' volumes: app-data: driver: local services: web: image: nginx:latest depends_on: - app volumes: - ./site.conf:/etc/nginx/conf.d/default.conf - app-data:/app app: build: . volumes: - app-data:/app a utility container update app-data volume like:
docker run --rm -it \ -v `pwd`/new-app:/source -v app-data:/target \ busybox /bin/sh -c "tar -cc /source . | tar -xc /target"
