We’re using 3 containers, which are [a] primary container (Ubuntu), [b] MySQL and [c] private container of related private app, and [c] is used to initialize MySQL database schema/data by running
rake db:migrate or similar commands. Of course, it requires connection between [c] and [b]. After initialization, tests are executed on primary container.
Two week ago (when we started to use this configuration), this configuration works well.
But 9 hours ago, the connection between [b] and [c] seems to become unavailable.
Is this a kind of bug? Or results of intentional CircleCI update?
This is strongly required for us to use different container images from testing repository to test on schema/data defined by different repository.
It is impossible as documented to use remote docker environment, so that the current configuration is only a hack to do it for us.
