Would be very handy to be able to connect to a running container from within a withRun block. I'm thinking it would behave exactly like inside(), except that it would run docker exec to run a command in the container. For example, if you needed to run a Postgres server with an extension installed, you could do it something like this:
script { image('postgres:10').withRun('-p 5432:5432') { c -> c.inside { // Attached to the Postgres container. sh "apt-get update" sh "apt-get install hypopg" } // Do stuff that relies on Postgres with hypopg } }
I would think there would be plenty of use cases for spinning up a container and doing a bit of configuration on it before using a service it provides.
