@girish said in Custom app container startup arguments:
these variables can then be configured by UI ? Also, I guess you are expecting these variables to become exposed as environment variables to the app?
I like the way this is implemented in the univention app center. The format of the settings (there they use the ini format) is explained in https://docs.software-univention.de/app-provider-5.0.html#app-settings:reference. It defines different types of settings and allows to template default values (even custom drop downs). The values are then stored in a file in the container and scripts can be triggered inside and outside of the container to react on changes. Outside is probably not necessary here.
