Hi,
I am using docker-compose to start a minio service and minio/mc container to create a default bucket. I cannot seem to be able to get the createbuckets service to return an exit code of any value other than 0 when a command in the entrypoint command string fails…anyone spot why this error is occurring?
For info…the entrypoint checks the success of the command to add minio as a host to the mc command client config. I have specified a restart policy of on on-failure so that I can signal a failure exit code of 1 if this fails, thus restarting the createbuckets service until it can connect to the minio service.
I am running docker-compose in MacOS. I have tried the script in a Linux OS environment and it works if I issue the command docker-compose -f myfile.yaml up minio createbuckets. In this case an exit with status 1 occurs in the event that createbuckets service fails to connect to the minio service. If I issue docker-compose -f myfile.yaml up in a Linux OS environment then the createbuckets service exits with status code 0 and no retry occurs. Why?
Any ideas?
Kind regards
