- line 3: psql returns 't' for true
- line 6: while loop used to re try uploading the model whenever the dataspace and anchor is ready
- line 8: sleep for number of seconds to allow the liquibase set up of the database via cps-and-ncmp container
- line 10-11: postgres commands to confirm that the needed dataspace and anchor exists (for this POC case subscription model requires the 'NCMP-Admin' dataspace and 'ncmp-dmi-registry' anchor)
- line 17: if condition specifies to only upload the model if dataspace and anchor exists
- line 21: command to get the IP address of 'cps-and-ncmp' docker container via ping's output manipulation and store in a variable; this variable is used in call of curl
- line 23-25: curl 'POST' commands to create dataspace, anchor and upload schemaset
- - model: contains the subscription model
- depends_on:
- -db: healthcheck is added on the db container/service which leaves seconds after the database has started
- -cps-and-ncmp: service should be started before init-db container is brought up
