$ docker run --name some-%%REPO%%2 -d -e CASSANDRA_SEEDS="$(docker inspect --format='{{ .NetworkSettings.IPAddress }}' some-%%REPO%%)" %%IMAGE%%:tag
$ docker run --name some-%%REPO%%2 -d -e CASSANDRA_SEEDS="$(docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' some-%%REPO%%)" %%IMAGE%%:tag
