启动 docker 服务时运行多个命令

Question

I am trying to run two different commands when doing docker-compose up.

My command: parameter looks like:

gunicorn --reload analytics_api:api --workers=3 --timeout 10000 -b :8083 && exec python /analytics/model_download.py

But when I run this the container fails with the error:

gunicorn: error: unrecognized arguments: && exec python /analytics/model_download.py

The second part of the command python /analytics/model_download.py , is used to download some dependencies from a sharedpath to a directory inside the container.

I want to run it while the service is up, not during the build.

What is going wrong here?

Answer 1

One way can be to have a startup shell script as the command which has both these entries

startup.sh

#start this in background if the other process need not wait for completion
exec python /analytics/model_download.py &
gunicorn --reload analytics_api:api --workers=3 --timeout 10000 -b :8083

while true 
 do
   sleep 5
done

Answer 2

Adding bash -c before the command solved the problem.

The command value will look like:

bash -c "python model_download.py && gunicorn --reload analytics_api:api -- workers=3 --timeout 10000 -b :8083"
