hi, [~Charo Zhang], [~eyang]
{code:java}
+ if (strcasecmp(network_type, "bridge") != 0) {
+ ret = 0;
+ goto cleanup;
+ }{code}
Not a bridge network, should it be able to perform port mapping as well?
We now use docker to create a parallel network via calico.
In the Hadoop submarine project, we still need to expose the services in the
container (for example: tensorboard, zeppelin, etc.).
