我想这样做,我可以在下面的代码中运行多个命令:
db:
image: postgres
web:
build: .
command: python manage.py migrate
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
links:
- db
如何执行多个命令?

这是我解决这个问题的方法:
services:
mongo1:
container_name: mongo1
image: mongo:4.4.4
restart: always
# OPTION 01:
# command: >
# bash -c "chmod +x /scripts/rs-init.sh
# && sh /scripts/rs-init.sh"
# OPTION 02:
entrypoint: [ "bash", "-c", "chmod +x /scripts/rs-init.sh && sh /scripts/rs-init.sh"]
ports:
- "9042:9042"
networks:
- mongo-cluster
volumes:
- ~/mongors/data1:/data/db
- ./rs-init.sh:/scripts/rs-init.sh
- api_vol:/data/db
environment:
*env-vars
depends_on:
- mongo2
- mongo3
我遇到了同样的问题,我想在端口3000上运行我的react应用程序,在端口6006上运行故事书,两者都在同一个容器中。
我尝试从Dockerfile作为入口点命令启动,并使用docker compose命令选项。
在花了一些时间之后,决定将这些服务分离到单独的容器中,这很有吸引力

想好了,使用bash-c。
例子:
command: bash -c "python manage.py migrate && python manage.py runserver 0.0.0.0:8000"
多行中的相同示例:
command: >
bash -c "python manage.py migrate
&& python manage.py runserver 0.0.0.0:8000"
Or:
command: bash -c "
python manage.py migrate
&& python manage.py runserver 0.0.0.0:8000
"
基于@Bjorn答案,docker最近引入了特殊的依赖规则,允许您等待“init容器”成功退出
db:
image: postgres
web:
image: app
command: python manage.py runserver 0.0.0.0:8000
depends_on:
db:
migration:
condition: service_completed_successfully
migration:
build: .
image: app
command: python manage.py migrate
depends_on:
- db
我不确定你是否还需要buildkit,但在我这边,它可以与
DOCKER_BUILDKIT=1 COMPOSE_DOCKER_CLI_BUILD=1 docker-compose up
