I have multiple servers for processing on workspace container

[seth-shi]

my servers:

api-1
api-2
api-3
admin

---

now, i need update code, first , I'm going to go to the admin server(enter workspace container exec command? or have more good idea)

git pull
docker-compose exec workspace bash
composer install
php artisan migrate
php artisan db:seed

i see workspace container have crontab job, but i run at only admin server.
in api server need composer install

git pull
docker-compose exec workspace bash
composer install

api-1, api-2, api-3 run worksapce(composer install need workspace), This results in the workspace container having four server running. crontab have four server run. but crontab should only one server run.
i think should stop workspace in api server.

Can you give me some idea?
