Jenkins is deployed automatically and cannot connect to the dependent service [solved]

Preface ：Docker Network problems

        If you used Docker Compose Start all dependent services , A network will be created by default , All the dependent services will be in this network , Services in different networks cannot access each other . The network I created here is deploy_default, So you need to specify sh The network on which the service runs in the script , Otherwise, the launched application service will not be able to connect to the dependent service .

• Use docker inspect mysql Order to see mysql The network where the service is located ;

•   adopt docker network ls To see all the networks ;

• Modify all sh Script , Modify the network where the service is running , Add a row  --network deploy_default \ that will do .

Be careful not to add near the command line "#" Note at the beginning of the sign , There will be no --network Wrong command .
