If you always want to create the same application (for example, for testing purposes), you need to create the application and specify a 32-character app ID.
Use the following command for that:
$ iectl publisher standalone-app create \
--appid "0c93bc0c96a14ad5a0c68d20d586f9a4" \ # 0c93bc0c96a14ad5a0c68d20d586f9a4 is unique application id of 32 characters, if it is not provided then auto generated application id will be used.
--reponame "mycompany" \ # mycompany relates to the repository name of the docker image.
--appdescription "my cool app" \
--iconpath "/path/to/my/icon.png" \
--appname "my cool app"\
NOTICE
To create always the same app, ensure you are always using the same argument values and app ID.
