-                  ## Health Strategy
-                  The :health strategy enables support for Docker's healthcheck feature,
-                  whereby you can directly leverage the healthy state of your container as your wait condition.

-                  (wait {:wait-strategy :health
-                         :startup-timeout 60} container)

-                  ## Log Strategy
-                  The :log strategy accepts a message which simply causes the output of your
-                  container's log to be used in determining if the container is ready or not.
-                  The output is `grepped` against the log message.
