我有一个与memcached和Docker一起使用的Django项目.当我在开发中使用sudo docker-compose up时,我希望清除整个缓存.除了在开发模式下禁用批发缓存外,还有一种方法可以在每次重新运行sudo docker-compose up时运行this question中所述的cache.clear()吗？
我不确定这是否应该输入：
> docker-entrypoint.sh
> Docker文件
> docker-compose.yml
>还有其他地方吗？
docker-compose.yml：
version: "3"
services:
redis:
image: "redis:alpine"
command: "redis-server --requirepass ${REDISPASS} --bind 0.0.0.0"
ports:
- '6379:6379'
memcached:
image: "memcached:latest"
ports:
- '11211:11211'
nginx:
image: nginx:latest
volumes:
- ./configuration/nginx/conf.d/:/etc/nginx/conf.d
- ./configuration/nginx/realtime:/etc/nginx/realtime
- ./static_cdn/static_root/static:/static
ports:
- 80:80
- 443:443
depends_on:
- app_main
- app_async_app1
- app_async_app2
app_main:
command: "djangoAppName.settings.prod ${SECRET_KEY} 1 ${DB_PASS} ${REDISPASS}"
image: "django_image_name"
ports:
- 0003:0003
volumes:
- ./static_cdn/static_root/:/static_cdn/
depends_on:
- redis
- memcached
app_async_app2:
command: "djangoAppName.settings.prod ${SECRET_KEY} 2 ${DB_PASS} ${REDISPASS}"
image: "django_image_name"
ports:
- 0002:0002
depends_on:
- redis
- memcached
- app_main
app_async_app1:
command: "djangoAppName.settings.prod ${SECRET_KEY} 3 ${DB_PASS} ${REDISPASS}"
image: "django_image_name"
depends_on:
- redis
- memcached
- app_main
ports:
- 0001:0001
react:
command: "npm run"
image: "django_image_name"
volumes:
- ./static_cdn/static_root/:/static_cdn/
depends_on:
- memcached
- app_main
根据this answer,您可以添加在清除缓存的memcached服务之前执行的服务.看起来您正在使用Linux Alpine,可以将此服务添加到docker-compose.yml中：
clearcache:
command: [sh,-c,"python manage.py clear_cache"]
然后添加到memcached：
memcached:
...
depends_on:
- clearcache
那里还有一个示例,它在同一命令中执行此操作,而不依赖于单独的服务(尽管我个人不喜欢这样做).
对于缓存清除命令,this answer提供了一些有用的讨论和帖子.
clear_cache.py：
from django.core.management.base import BaseCommand
from django.core.cache import cache
class Command(BaseCommand):
def handle(self,*args,**kwargs):
cache.clear()
self.stdout.write('Cleared cachen')
