-------------------------------------
Yes, agree
we have a private implementation to use self-defined environment variables such
as LINKER_CONF_SCRIPT and LINKER_CONF_PARAMS to handle the postconfig scripts.
But I do not think this is a standard implementation, we 100% agree that the
preconfig and postconfig should be put into TaskInfo.

> there should be one way to execute some scripts before and after the docker
> is created.
> Preconfiguration: for example, check the environments (IP addresses,
> Hostnames, Bridges, Volume directories) of the hosts where docker will run,
> and form the ENV for the docker and then run the docker with those
> environments.
> Postconfiguration: for example, use pipework to configure the docker, get the
> ports allocated and reports to another docker to configure relationships
> between applications between dockers.
> another postconfiguration example, after docker is shutdown, cleanup some
> data in the volumes
